lustrecomm PMDA
===============
This PMDA collects statistics common to all lustre implementations,
the statistics found in /proc/lustre and /proc/lnet
Note:
This PMDA may be remade from source and hence requires IDO (or
more specifically a C compiler) to be installed.
Uses of make(1) may fail (without removing or clobbering files)
if the C compiler cannot be found. This is most likely to
happen when running the PMDA ./Install script.
The only remedial action is to install the C compiler, or
hand-craft changes to the Makefile.
Metrics
=======
The file ./help contains descriptions for all of the metrics exported
by this PMDA.
Once the PMDA has been installed, the following command will list all
the available metrics and their explanatory "help" text:
$ pminfo -fT lustrecomm
Installation
============
+ # cd $PCP_PMDAS_DIR/lustrecomm
+ Check that there is no clash in the Performance Metrics Domain
defined in ./domain.h and the other PMDAs currently in use (see
$PCP_PMCDCONF_PATH). If there is, edit ./domain.h to choose another
domain number.
+ Then simply use
# ./Install
and choose both the "collector" and "monitor" installation
configuration options -- everything else is automated.
De-installation
===============
+ Simply use
# cd $PCP_PMDAS_DIR/lustrecomm
# ./Remove
Troubleshooting
===============
+ After installing or restarting the agent, the PMCD log file
($PCP_LOG_DIR/pmcd/pmcd.log) and the PMDA log file
($PCP_LOG_DIR/pmcd/trivial.log) should be checked for any warnings
or errors.
