How to Increase Server Performance by Disabling Cisco Transport Manager Performance Monitoring Alarms
February 1, 2008
This document explains how to disable the Cisco Transport Manager (CTM) threshold alarm for performance monitoring (PM) data collection.
CTM R8.0 and earlier has a built-in mechanism to monitor the collection of PM data from individual network elements (NEs). In the Control Panel > Alarm Configuration > Thresholds EMS Alarms tab, there is a threshold alarm variable named "PM Collection Time (seconds)." This threshold was designed to generate a minor, major, or critical EMS alarm if it takes CTM longer than the configured number of seconds to collect PM data for each NE. However, it was discovered that this threshold check generates an excessive number of Oracle triggers and creates a burden on the server. Consequently, this threshold was removed from CTM R8.5. It is recommended that you disable this EMS threshold in CTM R8.0 and earlier.
To disable the threshold, complete the following steps:
Step 1 Launch the CTM client and choose Administration > Control Panel > Alarm Configuration.
Step 2 In the Thresholds EMS Alarms tab, uncheck the Enable check box for the "PM Collection Time (seconds)" alarm.
Step 3 Click Save.
Note If PM data collection is disabled on the CTM server, there is no performance impact when enabling or disabling the PM Collection Time alarm. However, it is recommended that you disable this alarm even if PM data collection is disabled. Disabling the alarm improves performance if you decide later to collect PM data.
