# from its README: If running Alertmanager in high availability mode is not
#  desired, setting --cluster.listen-address= prevents Alertmanager from
#  listening to incoming peer requests.
# Why the fuck is that in the readme, not the docs below?
# If you don't add that, it will fail to start on boot because
# it doesn't wait for network.target, and gives this error message:
#  component=cluster err="couldn't deduce an advertise address: no private IP found, explicit advertise addr not provided"

# config.file and storage.path are set to match the debian package

# The alert manager supports the following options:


# --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.
# --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.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.
# --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.
