NAME
pmdasystemtap - Systemtap performance metrics domain agent (PMDA)
DESCRIPTION
pmdasystemtap is a Performance Metrics Domain Agent (PMDA) which exports metric values from the Linux Systemtap dynamic tracing toolkit. This implementation uses the stap(1) tool, which is a front-end to the Systemtap toolkit.
INSTALLATION
In order to access performance data exported by Systemtap from with PCP, it is necessary to perform two configuration steps: 1. Configure Systemtap probes, and verify them with stap(1). These should be produced in a format that is easily parsed, and then stored in the $PCP_PMDAS_DIR/systemtap/probes.stp file. 2. Configure pmdasystemtap to extract the values from the text produced by stap. Two example probes are implemented in the default systemtap PMDA script - readdir and sync traces (see $PCP_PMDAS_DIR/systemtap/pmdasystemtap.pl for details). # cd $PCP_PMDAS_DIR/systemtap # [ edit probes.stp, test /usr/bin/stap probes.stp ] # [ edit pmdasystemtap.pl ] Once this is setup, you can access the names and values for the systemtap performance metrics by doing the following as root: # cd $PCP_PMDAS_DIR/systemtap # ./Install If you want to undo the installation, do the following as root: # cd $PCP_PMDAS_DIR/systemtap # ./Remove pmdasystemtap is launched by pmcd(1) and should never be executed directly. The Install and Remove scripts notify pmcd(1) when the agent is installed or removed.
