Issue/Introduction

The url_response Timeout setting is set to 30 seconds (default) when you create a new profile. Some customers see timeout errors due to this out of the box default setting.

When a timeout occurs, the probe inserts a NULL value in the database, therefore, any related SLA calculations can potentially be impacted.

The alarms seem to come in waves: Server A will have 4 alarms from 4 of the 14 websites, but then work for another few hours with no problem. Usually, but not always, Server B will throw some alarms, but never from the same servers at the same time.

Often their presence in the alarm console/sub-console is short-lived as it can clear quickly.They are only visible via email alert or via nas Transaction history using a filter.

Environment

- Any UIM Release

Resolution

Set the Timeout for the profile(s) to 90 or higher. If this does not resolve the issue, you will likely need to investigate from the network/firewall side.

the following command can be helpful if you are running url_response from a Linux machine:

curl -v -i https://(url to test)

If "curl" cannot connect to the URL, neither can url_response.
