pgpool-II plugin for munin
Perl version implementation of munin_pgpool(Python) in repository https://github.com/vpetersson/munin_pgpool .
Copy pgpool2_connections into munin plugins directory such as /usr/share/munin/plugins and make symbolic link to the file like following commands:
# install -o root -m 0755 ./pgpool2_connections /usr/share/munin/plugins # ln -s /usr/share/munin/plugins/pgpool2_connections /etc/munin/plugins/
Configuration and Run
Edit plugin config file
# vi /etc/munin/plugin-conf.d/pgpool [pgpool2_*] env.host 127.0.0.1 env.port 9898 env.user munin env.userpwd password env.pcppath /path/to/pcp_pool_status
If "env.pcppath" is not defined, the plugin finds "pcp_pool_status" command from directories listed in $PATH environment variable. When the command is not installed your system, for example installed pgpool-II is 3.0 or older, the plugin gets the value of "num_init_children" from pgpool.conf file.
Run with munin-run command
# cd /etc/munin/plugins/ # munin-run ./pgpool2_connections wait.value 32 idle.value 88 max.value 120
