Recently, while testing after upgrading Aria Operations 8.16 to 8.17.1 Hotfix1, I found that I could not forward alerts via API to a remote monitoring system.
While testing an alert notification (Test Notification in a random alert). We see an error message at ‘Endpoint Receives Notification’.
After investigation, the problem appears to be in the JSON code in the payload template. Nothing had changed here and we may be dealing with a bug here. Let’s take a look at the payload template.
Payload Template working fine in 8.16 and is broken in 8.17.1 Hotfix1
In the payload template sample, we see in the JSON code section highlighted in green that the new line character ‘\n’ is used.
Payload Template working fine in 8.17.1 Hotfix1
In the next payload template sample, we see in the JSON code section highlighted in green that the new line character ‘\n’ is not used.
After we apply another test alert notification using the payload template without the new line character “\n” everything works fine.
I opened a ticket by VMware/Broadcom GSS and they confirmed the bug. It is now waiting for an update that fixes this issue. As soon as there is an update I will report it here.
