NAME

       corosync-qnetd-tool - corosync-qnetd control interface.

SYNOPSIS

       corosync-qnetd-tool [-Hhlsv] [-c cluster_name] [-p qnetd_ipc_socket_path]

DESCRIPTION

       corosync-qnetd-tool  is a frontend to the internal corosync-qnetd IPC. Its main purpose is
       to show important information about the current internal state of corosync-qnetd.

OPTIONS

       -H     Properly shutdown the corosync-qnetd process

       -h     Display a short usage text

       -l     List all clients connected to the corosync-qnetd process. The output  is  described
              in its own section below.

       -s     Display status of the corosync-qnetd process.

       -v     Display more verbose output for options -l and -s

       -c     Used  only  with  the -l option. By default, information about all clients from all
              clusters is displayed, with this option it's possible to filter information from  a
              single cluster given the cluster_name.

       -p     Path to the corosync-qnetd communication socket.

LIST COMMAND OUTPUT

       Cluster "Cluster":
           Algorithm:          Fifty-Fifty split (KAP Tie-breaker)
           Tie-breaker:        Node with lowest node ID
           Node ID 1:
               Client address:         ::ffff:127.0.0.1:52000
               HB interval:            8000ms
               Configured node list:   1, 2
               Ring ID:                1.a00000000021b40
               Membership node list:   1, 2
               TLS active:             Yes (client certificate verified)
               Vote:                   No change (ACK)
        ...

       The  output  contains  a  list  of  clusters.  Each cluster has the cluster common options
       Algorithm (optionally with Keep Active Partition Tie Breaker information) and  Tie-breaker
       as  configured in the corosync.conf file. Information about nodes follows.  Client address
       is the IP address and port of the client.  HB interval is the heartbeat  interval  between
       corosync-qnetd   and   corosync-qdevice   client.   This   option  can  be  configured  in
       corosync.conf.  Configured node list is the list of  nodes  configured  in  corosync.conf.
       Ring  ID  and  Membership  node  list  are  self-explanatory.   TLS active describes if an
       encrypted transport is used between  server  and  client.   Vote  is  last  vote  sent  to
       corosync-qdevice client. The last ACK/NACK vote (if it exists) is in parentheses.
