prometheus-alertmanager - Man Page

prometheus-alertmanager [<flags>]

-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=""

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.

--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.

--cluster.label=""

The cluster label is an optional string to include on each packet and stream. It uniquely identifies the cluster and prevents cross-communication issues when sending gossip messages.

--enable-feature=""

Experimental features to enable. The flag can be repeated to enable multiple features. Valid options: receiver-name-in-metrics, classic-mode, utf8-strict-mode

--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.
