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. FILES

NAME
pmdaroomtemp - room temperature performance metrics domain agent (PMDA) SYNOPSIS
$PCP_PMDAS_DIR/roomtemp/pmdaroomtemp [-d domain] [-l logfile] DESCRIPTION
pmdaroomtemp is a Performance Metrics Domain Agent (PMDA) which exports the temperature from one or more sensors built using the DS2480 and DS1280 chipsets and MicroLAN technology from Dallas Semiconductor Corporation. The roomtemp PMDA exports metrics that reflect the temperatures from one or more of these devices, in both degrees Celcius and Fahrenheit. Each metric has one instance for each temperature sensor device. The external instance identifiers are the serial numbers (in hex) of the DS1280 chips discovered when the MicroLAN was probed. A brief description of the pmdaroomtemp command line options follows: -d It is absolutely crucial that the performance metrics domain number specified here is unique and consistent. That is, domain should be different for every PMDA on the one host, and the same domain number should be used for the same PMDA on all hosts. -l Location of the log file. By default, a log file named roomtemp.log is written in the current directory of pmcd(1) when pmdaroomtemp is started, i.e. $PCP_LOG_DIR/pmcd. If the log file cannot be created or is not writable, output is written to the standard error instead. INSTALLATION
If you want access to the names, help text and values for the roomtemp performance metrics, do the following as root: # cd $PCP_PMDAS_DIR/roomtemp # ./Install If you want to undo the installation, do the following as root: # cd $PCP_PMDAS_DIR/roomtemp # ./Remove pmdaroomtemp 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. FILES

Environment variables with the prefix PCP_ are used to parameterize the file and directory names used by PCP. On each installation, the file /etc/pcp.conf contains the local values for these variables. The $PCP_CONF variable may be used to specify an alternative configura- tion file, as described in pcp.conf(5). SEE ALSO
