Command: serf monitor

The serf monitor command is used to connect and follow the logs of a running Serf agent. Monitor will show the recent logs and then continue to follow the logs, not exiting until interrupted or until the remote agent quits.

The power of the monitor command is that it allows you to log the agent at a relatively high log level (such as "warn"), but still access debug logs and watch the debug logs if necessary.

» Usage

Usage: serf monitor [options]

The command-line flags are all optional. The list of available flags are:

  • -log-level - The log level of the messages to show. By default this is "info". This log level can be more verbose than what the agent is configured to run at. Available log levels are "trace", "debug", "info", "warn", and "err".

  • -rpc-addr - Address to the RPC server of the agent you want to contact to send this command. If this isn't specified, the command will contact "" which is the default RPC address of a Serf agent. This option can also be controlled using the SERF_RPC_ADDR environment variable.

  • -rpc-auth - Optional RPC auth token. If the agent is configured to use an auth token, then this must be provided or the agent will refuse the command. This option can also be controlled using the SERF_RPC_AUTH environment variable.
