Example

Here is an example output:

    $ pcp_watchdog_info -h localhost -U postgres

    3 NO Linux_host1.localdomain_9991 host1

    Linux_host1.localdomain_9991 host1 9991 9001 7 STANDBY
    Linux_host2.localdomain_9992 host2 9992 9002 4 MASTER
    Linux_host3.localdomain_9993 host3 9993 9003 7 STANDBY
   

The result is in the following order:

    The first output line describes the watchdog cluster information:

    1. Total watchdog nodes in the cluster
    2. Is VIP is up on current node?
    3. Master node name
    4. Master node host
   

    Next is the list of watchdog nodes:

    1. node name
    2. hostname
    3. pgpool port
    4. watchdog port
    5. current node state
    6. current node state name
   

The --verbose option can help understand the output. For example:

   $ pcp_watchdog_info -h localhost -v -U postgres
