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
