NAME

       prometheus-alertmanager - The Prometheus alert manager

SYNOPSIS

       prometheus-alertmanager [<flags>]

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.

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

       --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.listen-address=":9093"
              Address to listen on for the web interface and API.

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

       --template.default="/usr/share/prometheus/alertmanager/default.tmpl"
              Path to default notification template.

       --cluster.listen-address="0.0.0.0:9094"
              Listen address for cluster.

       --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.

       --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.
