Hello Team,

I have a view with view elements using the same protocol for different regions

I need to group the alarm based on the below combination for each element under this view using alarm correlation.

I am not sure whether it can be done using

i. Group these alarms by alarms

ii.Group these alarms by elements

Also how we can create an alarm filter because we are filtering various alarm combination

Hi Ramesh,

I believe that should work fine with grouping by element. And your filtering should use and OR between the 2 filters on parameter descriptions.

So, something like this:

I hope this helps!

Hello Bert,

I am afraid I won't be able to use the "or" condition because as you can see below each alarm group has almost 2 or 3 alarms with same description(excluded the label because it is based on the element name).

The requirement is to group the alarms based on the combination of the alarms description.

Bert Vandenberghe [SLC] [DevOps Enabler] commented 23rd January 2025

Ah ok, this means you don't want to group on elements, but within one element you could have multiple groups based on the parameter description… There is a possibility to group on parameter, but I believe that won't work in your case because it looks like you want to group it based on a wildcard…

My suggestion would be to try this by splitting up this correlation rule in separate rules per parameter description wildcard. So, basically the screenshot I created before, but you remove the or-combination with that second parameter description wildcard filter. And then you duplicate the correlation rule and you change the parameter wildcard filter in the second correlation rule to the second filter. This way you need to create a correlation rule for each parameter description wildcard filter, but it should nicely take those alarms and group those alarms together per element.

If no grouping is needed per element, you can still remove that 'group these alarms by element' option. Then the alarms would be grouped across elements, purely based on the parameter description wildcard filter.

I hope this makes sense.
