# The alert manager supports the following options:
# --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.
# --log.level=info
# Only log messages with the given severity or above.
# --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.
