usage: prometheus [<flags>]

The Prometheus monitoring server

Flags:
  -h, --help                     Show context-sensitive help (also try --help-long and --help-man).
      --version                  Show application version.
      --config.file="prometheus.yml"
                                 Prometheus configuration file path.
      --web.listen-address="0.0.0.0:9090"
                                 Address to listen on for UI, API, and telemetry.
      --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.user-assets=<path>   Path to static 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="consoles"
                                 Path to the console template directory, available at /consoles.
      --web.console.libraries="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="data/"
                                 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.
      --storage.tsdb.retention.size=STORAGE.TSDB.RETENTION.SIZE
                                 [EXPERIMENTAL] Maximum number of bytes that can be stored for blocks. Units supported: KB, MB, GB, TB, PB. This flag is experimental and can be changed in future releases.
      --storage.tsdb.no-lockfile
                                 Do not create 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.
      --storage.remote.read-concurrent-limit=10
                                 Maximum number of concurrent remote read calls. 0 means no limit.
      --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.
      --query.timeout=2m         Maximum time a query may take before being aborted.
      --query.max-concurrency=20
                                 Maximum number of queries executed concurrently.

                                 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]
