Getting started with thresholds
Example scenarios
Threshold settings can be used to regulate the generation of a number of significant events that need immediate attention. There could be many different situations that might need your immediate attention, to understand the basics consider the following example scenario:
Example scenario: When the total CPU utilization of a Windows system crosses 80%, it may result in performance issues. In this case, you can specify an absolute threshold of 80% for the CPU Utilization attribute. Once the CPU utilization crosses the 80% limit, an event is triggered based on the combination of severity, minimum duration of breach, and other threshold settings.
Threshold management and user roles
To monitor and manage the thresholds settings, you must have the required permissions. Use this table to understand the mapping between areas and roles:
TrueSight console page | User role |
---|---|
Agent Thresholds (Both at monitor type and instance level) | Solutions Administrator and Tenant Administrator |
Server Global Thresholds | Solutions Administrator, Tenant Administrator, and Operations user |
Server Instance Thresholds | Solutions Administrator and Tenant Administrator |
Views to configure and manage thresholds from TrueSight console
- The agent thresholds (both instance and global) can be configured from the Agent Threshold tab under TrueSight console Configuration > Infrastructure Policies > Create Policies > Create Monitoring Policy page.
- The server-side instance thresholds can be configured from the Server Threshold tab under TrueSight console Configuration > Infrastructure Policies > Create Policies > Create Monitoring Policy page.
- The server-side global thresholds can be configured from the TrueSight console Configuration > Global Thresholds page.
Setting the upper and lower limit for thresholds
Infrastructure Management generates alarms when the set threshold of percentage of monitored instances is reached. You can set the upper limit and lower limit for these thresholds. The limits are based on the size of the environment: small, medium or large.
