The index of other Pgpool-II to get information for.
Index 0 gets one's self watchdog information.
If ommitted then gets information of all watchdog nodes.
See pcp_common_options.
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
