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

pmdamounts - filesystem mounts performance metrics domain agent (PMDA) SYNOPSIS
$PCP_PMDAS_DIR/mounts/pmdamounts [-d domain] [-l logfile] [-U username] DESCRIPTION
pmdamounts is a simple Performance Metrics Domain Agent (PMDA) which monitors availability of a given set of filesystem mounts. The mounts PMDA exports metrics that reflect whether the configured filesystems are mounted ("up") or not. The list of mount points to monitor is specified via the $PCP_PMDAS_DIR/mounts/mounts.conf file which simply contains one line for each mount point. Note that the platform kernel PMDA exports a more extensive set of filesystem metrics for every mounted filesystem - this PMDA is primarily intended for availability monitoring using the mounts.up metric. A brief description of the pmdamounts 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 mounts.log is written in the current directory of pmcd(1) when pmdamounts 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. -U User account under which to run the agent. The default is the unprivileged "pcp" account in current versions of PCP, but in older versions the superuser account ("root") was used by default. INSTALLATION
If you want access to the names, help text and values for the mounts performance metrics, do the following as root: # cd $PCP_PMDAS_DIR/mounts # ./Install If you want to undo the installation, do the following as root: # cd $PCP_PMDAS_DIR/mounts # ./Remove pmdamounts is launched by pmcd(1) and should never be executed directly.
