checkperf (Check System Performance)

The checkperf utility checks system performance in terms of CPU, memory, I/O, and network TCP. The default warning threshold for each of these items can be changed. Whenever one of the thresholds is reached, checkperf sends a warning email to a specified recipient. The email might include suggestions about how to improve system performance. This script is described and explained in the BigAdmin Tech Tip: Automating a System Performance Check Using the checkperf Utility http://www.sun.com/bigadmin/content/...perf_check.jsp

NAME
envmond - Environmental Monitoring daemon SYNOPSIS
/usr/sbin/envmond DESCRIPTION
Environmental Monitoring provides a means of detecting system threshold conditions, that if exceeded, could result in a loss of data or damage to the system itself. Using the envmond daemon, thresholds levels can be checked and corrective action can ensue before any damage occurs. The envmond daemon performs the following: Queries the system for exceeded threshold levels. Broadcasts a message to users warning of high threshold conditions or fan failure, and suggests corrective action. Sends a message to users when a high temperature condition has been resolved. Notifies all users that an orderly shutdown is to be initiated if recovery is not possible. To enable Environmental Monitoring, the envmond daemon must be started during the system boot, but after the eSNMP and Server System MIB agents have started. Before starting Environmental Monitoring, a system check is performed. If the system hardware does not support Envi- ronmental Monitoring, the envmond daemon and Server System MIB are not started. You can customize, start, and stop the envmond daemon using the envconfig utility. For more information, see the envconfig reference page. FILES
