DESCRIPTION

OPTIONS

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

       --config.file="/etc/prometheus/alertmanager.yml"
              Alertmanager configuration file name.

       --storage.path="/var/lib/prometheus/alertmanager/"
              Base path for data storage.

       --data.retention=120h
              How long to keep data for.

       --data.maintenance-interval=15m
              Interval  between  garbage  collection and snapshotting to disk of the silences and
              the notification logs.

       --alerts.gc-interval=30m
              Interval between alert GC.

       --web.systemd-socket
              Use systemd socket activation listeners instead of port listeners (Linux only).

       --web.listen-address=:9093
              Addresses on which to expose metrics and web  interface.  Repeatable  for  multiple
              addresses.

       --web.config.file=""
              [EXPERIMENTAL]  Path  to  configuration file that can enable TLS or authentication.
              See:           https://github.com/prometheus/exporter-toolkit/blob/master/docs/web-
              configuration.md

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

       --web.route-prefix=WEB.ROUTE-PREFIX
              Prefix   for   the   internal   routes  of  web  endpoints.  Defaults  to  path  of
              --web.external-url.

       --web.get-concurrency=0
              Maximum number of GET requests processed concurrently. If  negative  or  zero,  the
              limit is GOMAXPROC or 8, whichever is larger.

       --web.timeout=0
              Timeout for HTTP requests. If negative or zero, no timeout is set.

       --web.ui-path="/usr/share/prometheus/alertmanager/ui/"
              Path to static UI directory.

       --cluster.listen-address="0.0.0.0:9094"
              Listen address for cluster. Set to empty string to disable HA mode.

       --cluster.advertise-address=CLUSTER.ADVERTISE-ADDRESS
              Explicit address to advertise in cluster.

       --cluster.peer=CLUSTER.PEER
              Initial peers (may be repeated).

       --cluster.peer-timeout=15s
              Time to wait between peers to send notifications.

       --cluster.gossip-interval=200ms
              Interval  between  sending  gossip messages. By lowering this value (more frequent)
              gossip messages are propagated across the cluster more quickly at  the  expense  of
              increased bandwidth.

       --cluster.pushpull-interval=1m0s
              Interval  for  gossip state syncs. Setting this interval lower (more frequent) will
              increase convergence speeds across larger clusters  at  the  expense  of  increased
              bandwidth usage.

       --cluster.tcp-timeout=10s
              Timeout  for  establishing  a stream connection with a remote node for a full state
              sync, and for stream read and write operations.

       --cluster.probe-timeout=500ms
              Timeout to wait for an ack from a probed node before assuming it is unhealthy. This
              should be set to 99-percentile of RTT (round-trip time) on your network.

       --cluster.probe-interval=1s
              Interval  between random node probes. Setting this lower (more frequent) will cause
              the cluster to detect failed  nodes  more  quickly  at  the  expense  of  increased
              bandwidth usage.

       --cluster.settle-timeout=1m0s
              Maximum   time  to  wait  for  cluster  connections  to  settle  before  evaluating
              notifications.

       --cluster.reconnect-interval=10s
              Interval between attempting to reconnect to lost peers.

       --cluster.reconnect-timeout=6h0m0s
              Length of time to attempt to reconnect to a lost peer.

       --cluster.tls-config=""
              [EXPERIMENTAL] Path to config yaml file that  can  enable  mutual  TLS  within  the
              gossip protocol.

       --cluster.allow-insecure-public-advertise-address-discovery
              [EXPERIMENTAL] Allow alertmanager to discover and listen on a public IP address.

       --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]

       --version
              Show application version.
