NAME
pmdaib - Infiniband performance metrics domain agent (PMDA) SYNOPSYS
$PCP_PMDAS_DIR/infiniband/pmdaib [-c configFile] [-D debug] [-d domain] [-l logfile] [-w] DESCRIPTION
pmdaib is a Performance Metrics Domain Agent (PMDA) which exports information and performance metrics about local Infiniband HCAs and local or remote Infiniband GUIDs. A brief description of the pmdaib command line options follows: -c Location of the config file. By default, the config file is named $PCP_PMDAS_DIR/infiniband/config. See CONFIG FILE for more infor- mation. -D A debug values, as specified by pmdbg (1) -d Specify an alternate performance metrics domain number. Almost never necessary. -l Location of the log file. By default, a log file named ib.log is written to $PCP_LOG_DIR/pmcd. If the log file cannot be created or is not writable, output is written to the standard error instead. -w Write out the default config file to $PCP_PMDAS_DIRS/infiniband and exit immediately. The written config file will contain the local HCA ports. It will not overwrite an existing file. This argument should only be used to create the template config file and should never appear in pmcd.conf. See CONFIG FILE for more information on the file format and on monitoring remote GUIDs. CONFIG FILE
By default, the PMDA will operate without using a config file. In this mode of operation the local HCA ports will be monitored. Note that if a new HCA is added to the machine that instance domain naming may change because it will always be based on the kernel's naming. In cases where this is not acceptable, or in the case where monitoring remote Infiniband ports is required, a config file must be created. A "template" file can be created by running the pmdaib daemon with the -w argument. This will create a config file with the local ports and GUIDs. If the config file is executable then it will be run and the output will be used as the config file. The config file is composed of line-based records. Blank lines and everything after the hash (#) character are ignored. Each line has 6 fields: [instName] [portGUID] [portNum] via [localPortName]:[localPortNum] The first field is used to give a static instance name to the Infiniband port that has a specific GUID. All of the other fields must be properly specified in order to monitor a particular port. For example, to monitor port 1 of the local HCA called 'mthca0' a possible config file line would be: myPort1 0xdeadbeef01234567 1 via mthca0:1 Remote ports can be easily monitored by specifying the GUID of the HCA or switch and specifying the remote port number. The localPort- Name:localPortNum tuple specifies which local HCA and port to use as the "first hop" in contacting the remote GUID. E.g., to monitor port 13 of a remote switch which is connected to the fabric on the first port of the second HCA: switch13 0xfeeffeefabcdabcd 13 via mthca1:1 LOCAL CONTEXT
The Infiniband pmda also supports accessing the metrics via PM_CONTEXT_LOCAL when using the PMAPI interface. In order to use the Infini- band pmda in this way, set the environment variable PMDA_LOCAL_IB prior to calling pmNewContext(3). SEE ALSO

NAME
pmdaapache - Apache2 web server performance metrics domain agent (PMDA) SYNOPSIS
$PCP_PMDAS_DIR/apache/pmdaapache [-d domain] [-l logfile] [-U username] [-S server] [-P port] [-L location] DESCRIPTION
pmdaapache is a Performance Metrics Domain Agent (PMDA) which extracts performance metrics describing the state of an Apache web server. The apache PMDA exports metrics that measure the request rate, cumulative request sizes, uptime and various connection states for active clients. This information is obtained by performing a HTTP request to the server status URL, which must be enabled in the httpd.conf configuration file. ExtendedStatus on <Location /server-status> SetHandler server-status Order deny,allow Deny from all Allow from localhost </Location> A brief description of the pmdaapache 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 apache.log is written in the current directory of pmcd(1) when pmdaapache 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. -S Query the Apache status information from the named server rather than the local host. -P Query the Apache status information from the given port rather than the default (80). -L Specify an alternative location for finding the server-status page. -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 apache performance metrics, do the following as root: # cd $PCP_PMDAS_DIR/apache # ./Install If you want to undo the installation, do the following as root: # cd $PCP_PMDAS_DIR/apache # ./Remove pmdaapache 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
$PCP_PMCDCONF_PATH command line options used to launch pmdaapache $PCP_PMDAS_DIR/apache/help default help text file for the apache metrics $PCP_PMDAS_DIR/apache/Install installation script for the pmdaapache agent $PCP_PMDAS_DIR/apache/Remove undo installation script for the pmdaapache agent $PCP_LOG_DIR/pmcd/apache.log default log file for error messages and other information from pmdaapache PCP ENVIRONMENT
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
