Slow alarm cleaning from OneClick in Spectrum

Products

• CA Spectrum

Issue/Introduction

We have a problem deleting alarms, the clear is very slow, it takes a long time for the alarm to be deleted from the oneclick console, it takes about 15 or 20 seconds.
We were testing how to resolve it and in one test we stopped DNS and the issue was resolved, but we need to have the DNS started.
How we can resolve It?

 

Environment

Release : 21.2.x

Component : Spectrum Alarm

Cause

When Clear Alarm Action is triggered, login user  email id or user name is passed as part of host name which is internally passing to VBrokerCorbaHelper  to prepare appname and using InetAddress.getByName( hostName ), which is calling through DNS and causing delay.

Resolution

Will be fixed in the next Spectrum release to be out of box in 22.2.1

Cause:
When Clear Alarm Action is triggered, login user  email id or user name is passed as part of host name which is internally passing to VBrokerCorbaHelper  to prepare appname and using InetAddress.getByName( hostName ), which is calling through DNS and causing delay.

 

Solution

Provided support to pass user email id which is used to send email (From), so it will not effect host name/DNS call

If email id is not provided or not available(null), then logged in user name will be used as email id.
