Use Events to Monitor Device Performance

capm can be configured to generate events when devices deviate from normal performance expectations. These events help you monitor the health of your network and react to correct performance issues.

CA Performance Management
can be configured to generate events when devices deviate from normal performance expectations. These events help you monitor the health of your network and react to correct performance issues.
CA Performance Management
generates events using monitoring profiles. Monitoring profiles contain a set of event rules. Using metrics, these rules define the conditions that trigger events. To implement your event rules, associate the monitoring profile with a device collection.
Example:
An organization recently virtualized several business critical applications. The IT Architect and the Operations Center Manager want to monitor their virtual servers to ensure that the servers can handle the load from these applications. They create a monitoring profile, and they add event rules to find over-utilized CPUs and virtual memory issues for the collection of virtual devices. They associate the collection that includes the virtual servers with the monitoring profile.
CA Performance Management
automatically evaluates all the devices in the collection after every poll for each device. If needed,
CA Performance Management
raises or clears events when the devices trigger event rule conditions.
You can generate user-visible alarms in CA Spectrum from events that are processed and logged in
CA Performance Management
. For more information, see the CA Spectrum documentation.
To monitor device performance against specific thresholds, complete the following process:
Create a Custom Device Collection
The device collection defines which devices
CA Performance Management
monitors with a monitoring profile. To create a device collection that includes the target devices, create a custom group and add the devices to the group. Use group rules, or manually add the devices to the group.
For more information, see Groups.
Create a Monitoring Profile and Add Event Rules
To specify the conditions that generate an event, create a monitoring profile and add event rules to the profile.
For more information, see Configure Threshold Profiles.
Example:
The IT Architect and the Operations Center Manager define the threshold criteria. You add the following event rules:
  • Add a VMware memory utilization rule, as follows:
    • Violation occurs when memory utilization is above 80 percent for 300 seconds (5 minutes) within a 900-second (15-minute) window.
    • Clear the violation when the memory utilization is equal to or below 75 percent for 300 seconds within a 900-second window.
  • Add a VMware CPU utilization rule, as follows:
    • Violation occurs when both of the following conditions are met:
      • Condition 1: CPU utilization is above 70 percent.
      • Condition 2: CPU utilization is above one standard deviation.
    • These conditions occur for 300 seconds within a 900-second window.
Assign the Monitoring Profile to the Custom Device Collection
To begin monitoring the devices, and to activate event rules, assign the monitoring profile to the custom device collection.
Follow these steps:
  1. Navigate to the Data Aggregator data source.
  2. Click
    Monitoring Configuration
    ,
    Collections
    .
  3. Select the device collection, and click the
    Monitoring Profiles
    tab.
  4. Click
    Manage
    .
  5. Click and drag the monitoring profile to the
    Assigned Monitoring Profiles
    list.
  6. Click
    Save
    .
    CA Performance Management
    begins monitoring this collection of devices using the monitoring profile and event rules. Events that are generated appear in the Events Display dashboard.
    You can configure notifications for the threshold events. For more information, see Configure Notifications.
