--data.retention --log.level
alertmanager -h
usage: alertmanager [<flags>]
Flags:
-h, --[no-]help Show context-sensitive help (also try --help-long and --help-man).
--config.file="alertmanager.yml"
Alertmanager configuration file name.
--storage.path="data/" 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.
--silences.max-silences=0 Maximum number of silences, including expired silences. If negative or
zero, no limit is set.
--silences.max-silence-size-bytes=0
Maximum silence size in bytes. If negative or zero, no limit is set.
--alerts.gc-interval=30m Interval between alert GC.
--[no-]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. Examples: `:9100` or `[::1]:9100` for http,
`vsock://:9100` for vsock
--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.
--auto-gomemlimit.ratio=0.9
The ratio of reserved GOMEMLIMIT memory to the detected maximum
container or system memory. The value must be greater than 0 and less
than or equal to 1.
--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.
--[no-]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="" Comma-separated experimental features to enable. Valid options:
receiver-name-in-metrics, classic-mode, utf8-strict-mode,
auto-gomemlimit, auto-gomaxprocs
--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]
--[no-]version Show application version.
