The Libipmimonitoring implements a high level sensor monitoring API for IPMI sensors. The goal of this library is to abstract away all of the underlying IPMI details away from the user and map IPMI sensor readings into NOMINAL, WARNING, or CRITICAL states. By mapping sensor readings into NOMINAL, WARNING, or CRITICAL states, it makes monitoring sensors easier across large numbers of nodes. An iterator interface is also provided that allows the user to iterate through sensor values, types, units, and states.

In order to improve efficiency, SDR data will be cached on the host. By default it is cached in /var/cache/ipmimonitoringsdrcache.

Interpretation rules have not been written for all sensors permutations and types. If sensor interpretation rules are needed, please contact the developers as listed below.


The interpretation of sensors is configurable via the configuration file stored at /etc/ipmi_monitoring_sensors.conf. See ipmi_monitoring_sensors.conf(5) for more information on configuring sensor interpretations.
