Application alert become active unexpectedly for 2 or more https check scripts configured on telegraf

Products

• VCF Operations

Issue/Introduction

In Aria Operations, installation of Telegraf agent for application monitoring is successfully and the first custom http monitoring check is configured for website A and it creates new alert to get warning alarm when availability is 0, defined on that particular object (self) and works well.

However, creating another http monitoring check for website B on the same Telegraf Agent will result in website B monitoring check affecting alert for website A.

Environment

Aria Operations 8.18.x

Cause

Creating an alert that will trigger only for a specific http check object is not possible as if there are 2 or more http check objects for a single VM, there is no reliable name property for that object type.

However, there is a name property but depending on the OS type, the collection can be skipped.

Resolution

The general thought is to create an alert for each custom group and a child policy for each custom group, and then enable the corresponding alerts for the corresponding policies.

Follow KB: How to create Custom Groups and Alerts in Aria Operations to create custom group in the above sceanerio.

Additional Information

In the Symptoms/Condition tab (Step 2), selecting Select Specific Object as shown in the picture below, will not create an alert for that object because it is independent from object type
