How do I improve poller performance?

If polling times are too long and some graphs do not update correctly, it may be because RTM's default poller cmd.php cannot handle the high workload of larger LSF grid environments.

About this task

RTM comes installed with two main pollers:
  1. The LSF poller (lsfpollerd) for collecting LSF grid data from LSF management host daemons.
  2. The Cacti poller (cmd.php) for updating the time series graphs (that is, RRDtool graphs).
For small to medium grid environments, cmd.php works well. For larger environments, Cacti's Spine poller is recommended. The Spine poller can improve the polling and graphing performance of RTM (see the Cacti User Manual). This is discussed in the following topics:
