Alarm Table Performance

Solved1.12K views19th January 2023

Tiago Pinhao [SLC] [DevOps Enabler]813 5th January 2023 5 Comments

Hello all

Iv've created a simple dashboard that has a Time Range Feed and an alarm table from historical that will filter from a Saved Filter for SLA Protocol.

I find this to have some performance issues, when i try to get last 24Hours it will take 8 minutes to do so.

Any tips to improve this (Or potential known issues)

Hi Tiago,
Two questions in order to help you further:
Do you have an Elastic Db linked to DataMiner?
What version of DataMiner are you running?
Thx

Tiago Pinhao [SLC] [DevOps Enabler] commented 10th January 2023

Hello Pieter
Yes we have a 3 Elastic Server Cluster (Elastic 6.8.23) and we are running in Dataminer Feature 10.2.9.0-12190-CU1

I’ve also notice an issue on the network interface(Link at 10Mbps, probably cable issue) of one of the Elastic Servers, and the one that has the issue is the elected Master, I’m also waiting for them to fix that to get more deep analisys.

Let me know if there is any known issue also

Pieter Van Compernolle [SLC] [DevOps Enabler] commented 12th January 2023

Thx Tiago,
One more thing, do you have any idea about how many alarms you have in the cluster in 24 hours? Because I assume the protocol filtering will be a post filter on the server.

Tiago Pinhao [SLC] [DevOps Enabler] commented 12th January 2023

For the filter yes, they have for the last 24 Hours about 158000 Alarms

Pieter Van Compernolle [SLC] [DevOps Enabler] commented 19th January 2023

GQI will have a better performance then indeed like Rene mentioned.

Tiago,

If you are looking to load large number of alarms into the dashboard, I'd recommend using GQI (Link) and the table component (Table | DataMiner Docs). This combination allows you to make use of lazy loading which is much better for when large data sets need to be interfaced by the dashboard's module.

The regular alarm component could indeed be less performant for larger number of alarms.

Thank you,
