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.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.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.  Units
              supported:  KB,  MB,  GB,  TB,  PB. 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.

       --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]
