A.2. PCP Deployment

To monitor an entire cluster, the recommended approach is to install and configure PCP so that the GFS2 PMDA is enabled and loaded on each node of the cluster along with any other PCP services. You will then be able to monitor nodes either locally or remotely on a machine that has PCP installed with the corresponding PMDAs loaded in monitor mode. You may also install the optional pcp-gui package to allow graphical representation of trace data through the pmchart tool
For additional information, see the pcp-doc package, which is installed to /usr/share/doc/pcp-doc by default. PCP also provides a man page for every tool.
