Server Status

The server status can be obtained by executing a kill -5 <server-pid>. The status will be written to the standard output, by default the console output of the server. The dump contains the following information:

  • Current settings
  • Stack Trace of all the threads
  • Replication latency (if running in HA mode)
  • Replication messages statistics (if running in HA mode)
  • Distributed resources locked (if running in HA mode)
  • Record locks per database (if running in HA mode)

Below an example of a dump.
