Performance Manager User's Guide

Threshold Environment Variables

These environment variables are set up internally to retrieve threshold information from commands that you create. For example, the ./var/opt/pm/SMscripts/pm_mailer script sends detailed mail about the crossed threshold that uses this information. You can create your own shell script that acesses these values using the $ symbol in front of the variable, for example, $PMTHRESH_DESCRIPTION. These variables are helpful in creating your own logging script tht tracks thresholds and rearms of Performance Manager's metrics.
