mrtg-misc-probe probes different system features for mrtg to graph. It can probe percent usage of disk space and inodes for UFS and VxFS filesystems, number and total size of incoming and outgoing mail messages on a sendmail mail server, network delay using NTP peers/servers, number of clearcase vobs and views, number of Rational ClearCase and MultiSite licenses available and used, network device reachability (ping success), number of active and disconnected sessions of a Citrix Metaframe server, and number of hosts in a given network range.
mrtg-ntap-probe is a probe for MRTG 2.x. It retrieves the disk and file (inode) utilization by volume or quota tree name from Network Appliance Filers and NetCache Appliances. You do not need to find the right OID, which might change over time as you add and/or remove volumes and quota trees. It now also retrieves the disk space saved by A-SIS de-duplication by volume name.
