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
