7. Setup automated rules to write to the system log¶
Open the command shell and start pmieconf as the superuser:
$ cd /var/lib/pcp/config/pmieconf $ sudo su # mkdir mounts # cd mounts # [save the below code here in a file named as 'available']
#pmieconf-rules 1 # --- DO NOT MODIFY THIS FILE --- see pmieconf(5) # rule mounts.available default = "$rule$" predicate = "some_inst ( mounts.up $hosts$ $interfaces$ != 1 )" enabled = yes version = 1 help = "For at least one monitored mount point, a filesystem has not been detected mounted at the configured path for that mount."; string rule default = "Mount point is not available" modify = no display = no; instlist interfaces default = "" help = "May be set to a list of configured mount points for which the rule will be evaluated, as a subset of all configured pmdamounts(1) mount points. Mount points should be separated by white space and may be enclosed in single quotes, eg. \"/var /home\". Use the command: $ pminfo -f mounts.up to discover the names of all currently configured mount points."; string action_expand default = "[%i]@%h" display = no modify = no; string email_expand default = "host: %h mount %i is not available" display = no modify = no; # # --- DO NOT MODIFY THIS FILE --- see pmieconf(5)
To locate the mount points:
# pmieconf help mounts rule: mounts.available [Mount point is not available] help: For at least one monitored mount point, a filesystem has not been detected mounted at the configured path for that mount.
Start pmieconf interactively (as the superuser).
# pmieconf -f /var/lib/pcp/config/pmie/config.default
To enable the rules:
pmieconf> enable mounts
Quit the pmieconf:
pmieconf> quit /var/lib/pcp/config/pmie/config.default is in use by 1 running pmie process: 526929
Restart this process for the configuration change to take effect:
Use kill(1) to stop; e.g.
kill -INT 526929
Refer to pmie_check(1) for a convenient mechanism for restarting pmie daemons launched under the control of /etc/pcp/pmie/control; e.g.
# systemctl restart pmie
Check the status again:
# pmieconf status -f /var/lib/pcp/config/pmie/config.default verbose: off enabled rules: 21 of 29 pmie configuration file: /var/lib/pcp/config/pmie/config.default pmie process (PID) using this file: 749473
Search for the messages:
# grep pcp-pmie /var/log/messages
