Description
The IBM rPerf and SPEC CPU2006 extensions (maximum of 5 metrics) are contained in a separate DSO module (written in C) called mod_ibmrperf
. If installed, this DSO module is loaded during runtime/startup of gmond.
This DSO can be used to monitor the used physical CPUs in terms of rPerf and SPEC CPU2006 quantities. The SPEC CPU2006 values are calculated from the rPerf value.
Platform availability:
- AIX: minimum AIX5L V5.1 ML04 level or higher required
- Linux: SLES 9 or higher required, RHEL 4 Update 3 or higher required
Config file: /etc/ganglia/conf.d/ibmrperf.conf
Available metrics
The following 5 additional metrics are available:
rperf
- Currently used physical cores in units of
rPerf
(relative performance indicator for IBM Power Systems)
SPECint_rate2006
- Currently used physical cores in units of
SPECint_rate2006
value of SPEC CPU2006 benchmark suite
SPECint_base_rate2006
- Currently used physical cores in units of
SPECint_base_rate2006
value of SPEC CPU2006 benchmark suite
SPECfp_rate2006
- Currently used physical cores in units of
SPECfp_rate2006
value of SPEC CPU2006 benchmark suite
SPECfp_base_rate2006
- Currently used physical cores in units of
SPECfp_base_rate2006
value of SPEC CPU2006 benchmark suite
