                                 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.
