I have one comment regarding the sensor polling speed. With ipmitool you can generate a SDR cache that can be re-used to greatly speed up the reading of sensors over slow interfaces. (system interfaces and some lan interfaces) First, generate a cache: ipmitool sdr dump cache.sdr Then have ipmitool read it in for future queries: ipmitool -S cache.sdr sdr type temperature ipmitool -S cache.sdr sdr type voltage ipmitool -S cache.sdr sdr type fan These accesses should be much faster. Hopefully this can help address the slow polling speed but results will vary from system to system. -duncan |
