Fleet server configuration

Fleet server configuration options update the internals of the Fleet server (MySQL database, Redis, etc.). Modifying these options requires restarting your Fleet server.

Only self-managed users and customers can modify this configuration. If you're a managed-cloud customer, please reach out to Fleet about modifying the configuration.

You can specify configuration options in the following formats:

YAML file
Environment variables
Command-line flags

All duration-based settings accept valid time units of s, m, h.
Command-line flags can also be piped in via stdin.

MySQL

This section describes the configuration options for the primary. Suppose you also want to set up a read replica. In that case the options are the same, except that the YAML section is mysql_read_replica, and the flags have the mysql_read_replica_ prefix instead of mysql_ (the corresponding environment variables follow the same transformation). Note that there is no default value for mysql_read_replica_address, it must be set explicitly for Fleet to use a read replica, and it is recommended in that case to set a non-zero value for mysql_read_replica_conn_max_lifetime as in some environments, the replica's address may dynamically change to point from the primary to an actual distinct replica based on auto-scaling options, so existing idle connections need to be recycled periodically.

mysql_address

For the address of the MySQL server that Fleet should connect to, include the hostname and port.

Default value: localhost:3306
Environment variable: FLEET_MYSQL_ADDRESS
Config file format:
```
mysql:

```
FLEET_MYSQL_MAX_OPEN_CONNS * (max number of fleet servers) * 4
```

Fleet uses 3 prepared statements for authentication (used by Fleet API) + each database connection can be using 1 additional prepared statement.

Default value: intermediate
Environment variable: FLEET_SERVER_TLS_COMPATIBILITY

Config file format:

server:
  tls_compatibility: intermediate

server_url_prefix

Sets a URL prefix to use when serving the Fleet API and frontend. Prefixes should be in the form /apps/fleet (no trailing slash).

Note that some other configurations may need to be changed when modifying the URL prefix. In particular, URLs that are provided to osquery via flagfile, the configuration served by Fleet, the URL prefix used by fleetctl, and the redirect URL set with an identity provider.

Default value: Empty (no prefix set)
Environment variable: FLEET_SERVER_URL_PREFIX

Config file format:
```
server:
  keepalive: true
```

server_websockets_allow_unsafe_origin

Controls the servers websocket origin check. If your Fleet server is behind a reverse proxy, the Origin header may not reflect the client's true origin. In this case, you might need to disable the origin header (by setting this configuration to true) check or configure your reverse proxy to forward the correct Origin header.

Setting to true will disable the origin check.

Default value: false
Environment variable: FLEET_SERVER_WEBSOCKETS_ALLOW_UNSAFE_ORIGIN

Config file format:

server:
  websockets_allow_unsafe_origin: true

server_private_key

This key is required for enabling macOS MDM features and/or storing sensitive configs (passwords, API keys, etc.) in Fleet. If you are using the FLEET_APPLE_APNS_* and FLEET_APPLE_SCEP_* variables, Fleet will automatically encrypt the values of those variables using FLEET_SERVER_PRIVATE_KEY and save them in the database when you restart after updating.

The key must be at least 32 bytes long. Run openssl rand -base64 32 in the Terminal app to generate one on macOS.

Default value: ""
Environment variable: FLEET_SERVER_PRIVATE_KEY

Config file format:

server:
  private_key: 72414F4A688151F75D032F5CDA095FC4

Environment variable: FLEET_AUTH_BCRYPT_COST
Config file format:
```
auth:
  bcrypt_cost: 14
```

auth_salt_key_size

The key size of the salt which is generated when hashing user passwords.

Note: Fleet uses the bcrypt hashing algorithm for hashing passwords, which has a 72 character input limit. This means that the plaintext password (i.e. the password input by the user) length + the value of auth_salt_key_size cannot exceed 72. In the default case, the max length of a plaintext password is 48 (72 - 24).

Default value: 24
Environment variable: FLEET_AUTH_SALT_KEY_SIZE
Config file format:
```
auth:
  salt_key_size: 36
```

App

app_token_key_size

Size of generated app tokens.

Config file format:

app:
  enable_scheduled_query_stats: true

License

license_key

The license key provided to Fleet customers which provides access to Fleet Premium features.

Default value: 24
Environment variable: FLEET_OSQUERY_NODE_KEY_SIZE
Config file format:
```
osquery:
  node_key_size: 36
```

osquery_host_identifier

The identifier to use when determining uniqueness of hosts.

Options are provided (default), uuid, hostname, or instance.

This setting works in combination with the --host_identifier flag in osquery. In most deployments, using uuid will be the best option. The flag defaults to provided -- preserving the existing behavior of Fleet's handling of host identifiers -- using the identifier provided by osquery. instance, uuid, and hostname correspond to the same meanings as osquery's --host_identifier flag.

Users that have duplicate UUIDs in their environment can benefit from setting this flag to instance.

If you are enrolling your hosts using Fleet generated packages, it is reccommended to use uuid as your indentifier. This prevents potential issues with duplicate host enrollments.

Default value: provided
Environment variable: FLEET_OSQUERY_HOST_IDENTIFIER
Config file format:
```
osquery:
  host_identifier: uuid
```

osquery_enroll_cooldown

The cooldown period for host enrollment. If a host (uniquely identified by the osquery_host_identifier option) tries to enroll within this duration from the last enrollment, enroll will fail.

This flag can be used to control load on the database in scenarios in which many hosts are using the same identifier. Often configuring osquery_host_identifier to instance may be a better solution.

Default value: 0 (off)
Environment variable: FLEET_OSQUERY_ENROLL_COOLDOWN
Config file format:
```
osquery:
  enroll_cooldown: 1m
```

osquery_label_update_interval

The interval at which Fleet will ask Fleet's agent (fleetd) to update results for label queries.

Setting this to a higher value can reduce baseline load on the Fleet server in larger deployments.

Setting this to a lower value can increase baseline load significantly and cause performance issues or even outages. Proceed with caution.

Valid time units are s, m, h.

Default value: 1h
Environment variable: FLEET_OSQUERY_LABEL_UPDATE_INTERVAL
Config file format:
```
osquery:
  label_update_interval: 90m
```

osquery_policy_update_interval

The interval at which Fleet will ask Fleet's agent (fleetd) to update results for policy queries.

Setting this to a higher value can reduce baseline load on the Fleet server in larger deployments.

Setting this to a lower value can increase baseline load significantly and cause performance issues or even outages. Proceed with caution.

Valid time units are s, m, h.

Default value: 1h
Environment variable: FLEET_OSQUERY_POLICY_UPDATE_INTERVAL
Config file format:
```
osquery:
  policy_update_interval: 90m
```

osquery_detail_update_interval

The interval at which Fleet will ask Fleet's agent (fleetd) to update host details (such as uptime, hostname, network interfaces, etc.)

Setting this to a higher value can reduce baseline load on the Fleet server in larger deployments.

Setting this to a lower value can increase baseline load significantly and cause performance issues or even outages. Proceed with caution.

Valid time units are s, m, h.

Default value: 1h
Environment variable: FLEET_OSQUERY_DETAIL_UPDATE_INTERVAL
Config file format:
```
osquery:
  detail_update_interval: 90m
```

osquery_status_log_plugin

Options are filesystem, firehose, kinesis, lambda, pubsub, kafkarest, and stdout.

Default value: filesystem
Environment variable: FLEET_OSQUERY_STATUS_LOG_PLUGIN
Config file format:
```
osquery:
  status_log_plugin: firehose
```

osquery_result_log_plugin

This is the log output plugin that should be used for osquery result logs received from clients. Check out the reference documentation for log destinations.

Options are filesystem, firehose, kinesis, lambda, pubsub, kafkarest, and stdout.

Default value: filesystem
Environment variable: FLEET_OSQUERY_RESULT_LOG_PLUGIN
Config file format:
```
osquery:
  result_log_plugin: firehose
```

osquery_max_jitter_percent

Given an update interval (label, or details), this will add up to the defined percentage in randomness to the interval.

The goal of this is to prevent all hosts from checking in with data at the same time.

So for example, if the label_update_interval is 1h, and this is set to 10. It'll add up a random number between 0 and 6 minutes to the amount of time it takes for Fleet to give the host the label queries.

Default value: 10
Environment variable: FLEET_OSQUERY_MAX_JITTER_PERCENT
Config file format:
```
osquery:
  max_jitter_percent: 10
```

osquery_enable_async_host_processing

Experimental feature. Enable asynchronous processing of hosts' query results. Currently, asyncronous processing is only supported for label query execution, policy membership results, hosts' last seen timestamp, and hosts' scheduled query statistics. This may improve the performance and CPU usage of the Fleet instances and MySQL database servers for setups with a large number of hosts while requiring more resources from Redis server(s).

Note that currently, if both the failing policies webhook and this osquery.enable_async_host_processing option are set, some failing policies webhooks could be missing (some transitions from succeeding to failing or vice-versa could happen without triggering a webhook request).

It can be set to a single boolean value ("true" or "false"), which controls all async host processing tasks, or it can be set for specific async tasks using a syntax similar to an URL query string or parameters in a Data Source Name (DSN) string, e.g., "label_membership=true&policy_membership=true". When using the per-task syntax, omitted tasks get the default value. The supported async task names are:

label_membership for updating the hosts' label query execution;
policy_membership for updating the hosts' policy membership results;
host_last_seen for updating the hosts' last seen timestamp.
scheduled_query_stats for saving the hosts' scheduled query statistics.

Default value: false
Environment variable: FLEET_OSQUERY_ENABLE_ASYNC_HOST_PROCESSING

Config file format:

osquery:
  enable_async_host_processing: true

Fleet tested this option for policy_membership=true in this issue and found that it does not impact the performance or behavior of the app.

osquery_async_host_collect_interval

Applies only when osquery_enable_async_host_processing is enabled. Sets the interval at which the host data will be collected into the database. Each Fleet instance will attempt to do the collection at this interval (with some optional jitter added, see osquery_async_host_collect_max_jitter_percent), with only one succeeding to get the exclusive lock.

It can be set to a single duration value (e.g., "30s"), which defines the interval for all async host processing tasks, or it can be set for specific async tasks using a syntax similar to an URL query string or parameters in a Data Source Name (DSN) string, e.g., "label_membership=10s&policy_membership=1m". When using the per-task syntax, omitted tasks get the default value. See osquery_enable_async_host_processing for the supported async task names.

Default value: 30s
Environment variable: FLEET_OSQUERY_ASYNC_HOST_COLLECT_INTERVAL

Config file format:

osquery:
  async_host_collect_interval: 1m

Default value: 10
Environment variable: FLEET_OSQUERY_ASYNC_HOST_COLLECT_MAX_JITTER_PERCENT

Config file format:

osquery:
  async_host_collect_max_jitter_percent: 5

osquery_async_host_collect_lock_timeout

Applies only when osquery_enable_async_host_processing is enabled. Timeout of the lock acquired by a Fleet instance to collect host data into the database. If the collection runs for too long or the instance crashes unexpectedly, the lock will be automatically released after this duration and another Fleet instance can proceed with the next collection.

It can be set to a single duration value (e.g., "1m"), which defines the lock timeout for all async host processing tasks, or it can be set for specific async tasks using a syntax similar to an URL query string or parameters in a Data Source Name (DSN) string, e.g., "label_membership=2m&policy_membership=5m". When using the per-task syntax, omitted tasks get the default value. See osquery_enable_async_host_processing for the supported async task names.

Default value: 1m
Environment variable: FLEET_OSQUERY_ASYNC_HOST_COLLECT_LOCK_TIMEOUT

Config file format:

osquery:
  async_host_collect_lock_timeout: 5m

osquery_async_host_collect_log_stats_interval

Config file format:

osquery:
  async_host_redis_scan_keys_count: 100

osquery_min_software_last_opened_at_diff

The minimum time difference between the software's "last opened at" timestamp reported by osquery and the last timestamp saved for that software on that host helps minimize the number of updates required when a host reports its installed software information, resulting in less load on the database. If there is no existing timestamp for the software on that host (or if the software was not installed on that host previously), the new timestamp is automatically saved.

Upgrades

allow_missing_migrations

If set then fleet serve will run even if there are database migrations missing.

Default value: false
Environment variable: FLEET_UPGRADES_ALLOW_MISSING_MIGRATIONS

Config file format:

upgrades:
  allow_missing_migrations: true

Vulnerabilities

databases_path

The path specified needs to exist and Fleet needs to be able to read and write to and from it. This is the only mandatory configuration needed for vulnerability processing to work.

When disable_schedule is set to false (the default), Fleet instances will try to create the databases_path if it doesn't exist.

Default value: /tmp/vulndbs
Environment variable: FLEET_VULNERABILITIES_DATABASES_PATH

Config file format:

vulnerabilities:
  databases_path: /some/path

periodicity

How often vulnerabilities are checked. This is also the interval at which the counts of hosts per software is calculated.

Default value: 1h
Environment variable: FLEET_VULNERABILITIES_PERIODICITY
Config file format:
```
vulnerabilities:
  periodicity: 1h
```

cpe_database_url

You can fetch the CPE dictionary database from this URL. Some users want to control where Fleet gets its database. When Fleet sees this value defined, it downloads the file directly. It expects a file in the same format that can be found in https://github.com/fleetdm/nvd/releases. If this value is not defined, Fleet checks for the latest release in Github and only downloads it if needed.

Default value: ""
Environment variable: FLEET_VULNERABILITIES_CPE_DATABASE_URL
Config file format:
```
vulnerabilities:
  cpe_database_url: ""
```

cpe_translations_url

You can fetch the CPE translations from this URL. Translations are used when matching software to CPE entries in the CPE database that would otherwise be missed for various reasons. When Fleet sees this value defined, it downloads the file directly. It expects a file in the same format that can be found in https://github.com/fleetdm/nvd/releases. If this value is not defined, Fleet checks for the latest release in Github and only downloads it if needed.

Default value: ""
Environment variable: FLEET_VULNERABILITIES_CPE_TRANSLATIONS_URL

Config file format:

vulnerabilities:
  cpe_translations_url: ""

cve_feed_prefix_url

Like the CPE dictionary, we allow users to define where to get the legacy CVE feeds from. In this case, the URL should be a host that serves the files in the legacy feed format. Fleet expects to find all the GZ and META files that can be found in https://nvd.nist.gov/vuln/data-feeds#JSON_FEED. For example: FLEET_VULNERABILITIES_CVE_FEED_PREFIX_URL + /nvdcve-1.1-2002.meta

When not defined, Fleet downloads CVE information from the nvd.nist.gov host using the NVD 2.0 API.

Default value: ""
Environment variable: FLEET_VULNERABILITIES_CVE_FEED_PREFIX_URL

Config file format:

vulnerabilities:
  cve_feed_prefix_url: ""

disable_schedule

When running multiple instances of the Fleet server, by default, one of them dynamically takes the lead in vulnerability processing. This lead can change over time. Some Fleet users want to be able to define which deployment is doing this checking. If you wish to do this, you'll need to deploy your Fleet instances with this set explicitly to true and one of them set to false.

Similarly, to externally manage running vulnerability processing, set the value to true for all Fleet instances and then run fleet vuln_processing using external tools like crontab.

Default value: false
Environment variable: FLEET_VULNERABILITIES_DISABLE_SCHEDULE

Config file format:

vulnerabilities:
  disable_schedule: false

disable_data_sync

Fleet by default automatically downloads and keeps the different data streams needed to properly do vulnerability processing. In some setups, this behavior is not wanted, as access to outside resources might be blocked, or the data stream files might need review/audit before use.

In order to support vulnerability processing in such environments, we allow users to disable automatic sync of data streams with this configuration value.

To download the data streams, you can use fleetctl vulnerability-data-stream --dir ./somedir. The contents downloaded can then be reviewed, and finally uploaded to the defined databases_path in the fleet instance(s) doing the vulnerability processing.

Default value: false
Environment variable: FLEET_VULNERABILITIES_DISABLE_DATA_SYNC

Config file format:

vulnerabilities:
  disable_data_sync: true

recent_vulnerability_max_age

Maximum age of a vulnerability (a CVE) to be considered "recent". The age is calculated based on the published date of the CVE in the National Vulnerability Database (NVD). Recent vulnerabilities play a special role in Fleet's automations, as they are reported when discovered on a host if the vulnerabilities webhook or a vulnerability integration is enabled.

Default value: 720h (30 days)
Environment variable: FLEET_VULNERABILITIES_RECENT_VULNERABILITY_MAX_AGE

Config file format:

vulnerabilities:
     recent_vulnerability_max_age: 48h

disable_win_os_vulnerabilities

If using osquery 5.4 or later, Fleet by default will fetch and store all applied Windows updates and use that for detecting Windows vulnerabilities — which might be a writing-intensive process (depending on the number of Windows hosts in your Fleet). Setting this to true will cause Fleet to skip both processes.

Default value: false
Environment variable: FLEET_VULNERABILITIES_DISABLE_WIN_OS_VULNERABILITIES

Config file format:

vulnerabilities:
  disable_win_os_vulnerabilities: true

GeoIP

database_path

The path to a valid Maxmind GeoIP database (mmdb). Support exists for the country & city versions of the database. If city database is supplied then Fleet will attempt to resolve the location via the city lookup, otherwise it defaults to the country lookup. The IP address used to determine location is extracted via HTTP headers in the following order: True-Client-IP, X-Real-IP, and finally X-FORWARDED-FOR headers on the Fleet web server.

You can get a copy of the Geolite2 database for free by creating an account on the MaxMind website, navigating to the download page, and downloading the GZIP archive. Decompress it and place the mmdb file somewhere fleet can access.

It is also possible to automatically keep the database up to date, see the documentation from MaxMind.

GeoIP databases can find what general area a device is from, but not the exact location. They work by collecting which IP addresses ISPs use for different cities and countries and packaging them up into a list mapping IP address to city.

You've likely seen services use GeoIP databases if they redirect you to a site specific to your country. e.g. Google will redirect you to google.ca if you visit from Canada or Mouser will change to your local currency if you view an electronic component.

This can be useful for your fleet install if you want to tell if a device is somewhere it shouldn't be. If a desktop machine located at a site in New York suddenly appears in London, then you can tell that something is wrong. It can also help you differentiate machines if they have similar names, e.g. if you have two computers "John's MacBook Pro".

While it can be a useful tool, an unexpected result could be an error in the database, a user connecting via a mobile network which uses the same IP address for a wide area, or a user visiting family. Checking on the location of devices too often could be invasive to employees who are keeping work devices on them for e.g. oncall responsibilities.

Default value: none
Environment variable: FLEET_GEOIP_DATABASE_PATH

Config file format:

geoip:
  database_path: /some/path/to/geolite2.mmdb

Sentry

DSN

If set, then Fleet serve will capture errors and panics and push them to Sentry.

Default value: ""
Environment variable: FLEET_SENTRY_DSN

Config file format:

sentry:
  dsn: "https://somedsnprovidedby.sentry.com/"

Prometheus

basic_auth.username

This is the username to use for HTTP Basic Auth on the /metrics endpoint.

If basic_auth.username is not set, then:

If basic_auth.disable is not set then the Prometheus /metrics endpoint is disabled.
If basic_auth.disable is set then the Prometheus /metrics endpoint is enabled but without HTTP Basic Auth.
Default value: ""
Environment variable: FLEET_PROMETHEUS_BASIC_AUTH_USERNAME

Config file format:

prometheus:
  basic_auth:
    username: "foo"

basic_auth.password

This is the password to use for HTTP Basic Auth on the /metrics endpoint.

If basic_auth.password is not set, then:

If basic_auth.disable is not set then the Prometheus /metrics endpoint is disabled.
If basic_auth.disable is set then the Prometheus /metrics endpoint is enabled but without HTTP Basic Auth.
Default value: ""
Environment variable: FLEET_PROMETHEUS_BASIC_AUTH_PASSWORD

Config file format:

prometheus:
  basic_auth:
    password: "bar"

basic_auth.disable

This allows running the Prometheus endpoint /metrics without HTTP Basic Auth.

If both basic_auth.username and basic_auth.password are set, then this setting is ignored.

Default value: false
Environment variable: FLEET_PROMETHEUS_BASIC_AUTH_DISABLE

Config file format:

prometheus:
  basic_auth:
    disable: true

Mobile device management (MDM)

The server_private_key configuration option is required for macOS MDM features.

The Apple Push Notification service (APNs), Simple Certificate Enrollment Protocol (SCEP), and Apple Business Manager (ABM) certificate and key configuration are deprecated as of Fleet 4.51. They are maintained for backwards compatibility. Please upload your APNs certificate and ABM token. Learn how here.

mdm.apple_dep_sync_periodicity

The duration between DEP device syncing (fetching and setting of DEP profiles). Only relevant if Apple Business Manager (ABM) is configured.

Default value: 1m
Environment variable: FLEET_MDM_APPLE_DEP_SYNC_PERIODICITY
Config file format:
```
mdm:
  apple_dep_sync_periodicity: 10m
```

mdm.windows_wstep_identity_cert_bytes

The content of the Windows WSTEP identity certificate. An X.509 certificate, PEM-encoded.

Default value: ""
Environment variable: FLEET_MDM_WINDOWS_WSTEP_IDENTITY_CERT_BYTES

Config file format:

mdm:
 windows_wstep_identity_cert_bytes: |
    -----BEGIN CERTIFICATE-----
    ... PEM-encoded content ...
