SYNOPSIS¶

prometheus [<flags>]

DESCRIPTION¶

The Prometheus monitoring server

OPTIONS¶

-h, --help

Show context-sensitive help (also try --help-long and --help-man).

--version

Show application version.

--config.file="/etc/prometheus/prometheus.yml"

Prometheus configuration file path.

--web.listen-address="0.0.0.0:9090"

Address to listen on for UI, API, and telemetry.

--web.config.file=""

[EXPERIMENTAL] Path to configuration file that can enable TLS or authentication.

--web.read-timeout=5m

Maximum duration before timing out read of the request, and closing idle connections.

--web.max-connections=512

Maximum number of simultaneous connections.

--web.external-url=<URL>

The URL under which Prometheus is externally reachable (for example, if Prometheus is served via a reverse proxy). Used for generating relative and absolute links back to Prometheus itself. If the URL has a path portion, it will be used to prefix all HTTP endpoints served by Prometheus. If omitted, relevant URL components will be derived automatically.

--web.route-prefix=<path>

Prefix for the internal routes of web endpoints. Defaults to path of --web.external-url.

--web.local-assets="/usr/share/prometheus/web/"

Path to static asset/templates directory.

--web.user-assets=<path>

Path to user asset directory, available at /user.

--web.enable-lifecycle

Enable shutdown and reload via HTTP request.

--web.enable-admin-api

Enable API endpoints for admin control actions.

--web.console.templates="/etc/prometheus/consoles"

Path to the console template directory, available at /consoles.

--web.console.libraries="/etc/prometheus/console_libraries"

Path to the console library directory.

--web.page-title="Prometheus Time Series Collection and Processing Server"

Document title of Prometheus instance.

--web.cors.origin=".*"

Regex for CORS origin. It is fully anchored. Example: 'https?://(domain1|domain2).com'

--storage.tsdb.path="/var/lib/prometheus/metrics2/"

Base path for metrics storage.

--storage.tsdb.retention=STORAGE.TSDB.RETENTION

[DEPRECATED] How long to retain samples in storage. This flag has been deprecated, use "storage.tsdb.retention.time" instead.

--storage.tsdb.retention.time=STORAGE.TSDB.RETENTION.TIME

How long to retain samples in storage. When this flag is set it overrides "storage.tsdb.retention". If neither this flag nor "storage.tsdb.retention" nor "storage.tsdb.retention.size" is set, the retention time defaults to 15d. Units Supported: y, w, d, h, m, s, ms.

--storage.tsdb.retention.size=STORAGE.TSDB.RETENTION.SIZE

[EXPERIMENTAL] Maximum number of bytes that can be stored for blocks. A unit is required, supported units: B, KB, MB, GB, TB, PB, EB. Ex: "512MB". This flag is experimental and can be changed in future releases.

--storage.tsdb.use-lockfile

Create a lockfile in data directory.

--storage.tsdb.allow-overlapping-blocks

[EXPERIMENTAL] Allow overlapping blocks, which in turn enables vertical compaction and vertical query merge.

--storage.tsdb.wal-compression

Compress the tsdb WAL.

--storage.remote.flush-deadline=<duration>

How long to wait flushing sample on shutdown or config reload.

--storage.remote.read-sample-limit=5e7

Maximum overall number of samples to return via the remote read interface, in a single query. 0 means no limit. This limit is ignored for streamed response types.

--storage.remote.read-concurrent-limit=10

Maximum number of concurrent remote read calls. 0 means no limit.

--storage.remote.read-max-bytes-in-frame=1048576

Maximum number of bytes in a single frame for streaming remote read response types before marshalling. Note that client might have limit on frame size as well. 1MB as recommended by protobuf by default.

--rules.alert.for-outage-tolerance=1h

Max time to tolerate prometheus outage for restoring "for" state of alert.

--rules.alert.for-grace-period=10m

Minimum duration between alert and restored "for" state. This is maintained only for alerts with configured "for" time greater than grace period.

--rules.alert.resend-delay=1m

Minimum amount of time to wait before resending an alert to Alertmanager.

--alertmanager.notification-queue-capacity=10000

The capacity of the queue for pending Alertmanager notifications.

--alertmanager.timeout=10s

Timeout for sending alerts to Alertmanager.

--query.lookback-delta=5m

The maximum lookback duration for retrieving metrics during expression evaluations and federation.

--query.timeout=2m

Maximum time a query may take before being aborted.

--query.max-concurrency=20

Maximum number of queries executed concurrently.

--query.max-samples=50000000

Maximum number of samples a single query can load into memory. Note that queries will fail if they try to load more samples than this into memory, so this also limits the number of samples a query can return.

--log.level=info

Only log messages with the given severity or above. One of: [debug, info, warn, error]

--log.format=logfmt

Output format of log messages. One of: [logfmt, json]
