Description
Recently, I've been experiencing problems with some customers associated with file descriptors on the machine running either OpenNMS or Minion.
It turns out that via JMX it is possible to get the number of used FDs, and the allocated maximum, which is what you usually control via MAXIMUM_FILE_DESCRIPTORS in OpenNMS through $OPENNMS_HOME/etc/opennms.conf, or via MAX_FD in /etc/sysconfig/minion for Minion.
For this reason, I found very useful to be able to store and graph those metrics.
