NAME¶

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

Path to static assets/templates directory.

--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.
