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 Watchdog Cluster Information Total Nodes : 3 Remote Nodes : 2 Quorum state : QUORUM EXIST Alive Remote Nodes : 2 VIP up on local node : NO Master Node Name : Linux_host2.localdomain_9992 Master Host Name : localhost Watchdog Node Information Node Name : Linux_host1.localdomain_9991 Host Name : host1 Delegate IP : 192.168.1.10 Pgpool port : 9991 Watchdog port : 9001 Node priority : 1 Status : 7 Status Name : STANDBY Node Name : Linux_host2.localdomain_9992 Host Name : host2 Delegate IP : 192.168.1.10 Pgpool port : 9992 Watchdog port : 9002 Node priority : 1 Status : 4 Status Name : MASTER Node Name : Linux_host3.localdomain_9993 Host Name : host3 Delegate IP : 192.168.1.10 Pgpool port : 9993 Watchdog port : 9003 Node priority : 1 Status : 7 Status Name : STANDBY
