Performance Alerts

Configuring IP Resource Monitoring › Performance Alerts

Performance Alerts

You can configure the CA NetMaster NM for TCP/IP region to raise alerts on any performance attribute samples when certain criteria are met. The alert is then displayed on the alert monitor.

Alerts can be raised on a performance attribute when the following occurs:

A sample value is above or below an absolute threshold value, for example, PINGRTT for IP host SERVER01 exceeds 2000ms
A sample value differs from a moving average by more or less than a specified percentage, for example, ConBytes for IP application APPL01 is more than 80% above what it usually is for this hour of this day
An enumerated value is or is not a specified character value, for example, NETSTATUS=SNMPERROR

Performance data attributes generally fall into the following categories:

Availability, Stability, and Reliability: Specifies whether the resource is active, reachable, and responsive.
Throughput: Specifies how many bytes, packets, datagrams, segments went through, in an interval.
Errors: Specifies how many errors occurred in an interval.
Response Time: Specifies the actual response time. Possibly the lowest, highest, average, in an interval.
Workload: Specifies how much work an application user did in an interval.
Capacity and Utilization: Specifies how much of its internal resources a device is using.
Resource Usage: Specifies how much of the external system resources a device is using.
Configuration: Specifies device and environmental configuration.

Define a Performance Alert

You can define a performance alert after you have defined performance monitoring. The process is the same for stack resources and other IP resources; however, the procedure to access the Monitoring Definition list differs.

To define a performance alert

From the Monitoring Definition list, enter U beside the attribute for which you want to raise an alert.
The Alert Control Details panel appears.
Enter U beside the type of alert that you want to raise.
The Alert Details panel appears.
Enter the details of the alert and then press F3 (OK).
Note: For information about the fields, press F1 (Help).
Press F3 (OK).
The details are saved.

Example: Define a Performance Alert

This example shows how to raise a severity 3 alert when the total number of FTP failures on STACK01 exceeds 100 per hour. You want the text on the alert monitor to say, Excessive FTP Failures.

To define the alert

Enter /IPMON at the command prompt.
The IP resource monitor appears.
Enter UM beside the stack for which you want to define monitoring.
The Monitoring Definition panel appears.
Enter U beside FTP Workload Monitoring.
The Monitoring Definition List appears.
Press F4 (Add).
The Selectable Attributes List appears.
Enter S beside FTPTotalFailures.
The Monitoring Definition List appears.
Enter U beside FTPTotalFailures.
The Alert Control Details panel appears.
Enter U beside High Rate Alert.
The High Rate Alert Details panel appears.

Enter the alert details as follows:
