These are plugins for the monitoring tool Munin which can be used to monitor the number of active drones for any OpenSRF service. There are three graphs available:
This graph is quite messy but useful for an overview of services.
This graph represents the max_children as a red line and the number of drones in use as a green line.
This graph represents a single service's drones as a percentage of the max_children.
Place somewhere with executable permissions for munin user, symlink to your munin plugins directory (/etc/munin/plugins)
Place somewhere with executable permissions for munin user, symlink to your munin plugins directory (/etc/munin/plugins). The symlink should be named after the service you wish to monitor, for example:
ln -sf /opt/eg-munin/openils-percent.pl /etc/munin/plugins/openils_cstore
That's it. Then restart your munin-node and wait about a half hour for data to accumulate. See the source of the files to adjust the warnings or adjust the warnings in your munin.conf
