If you are using or have used Operations Manager i (OMi), then you might be familiar with the Correlation Composer or ECS Designer functionality which was used to correlate events within OVO. Similarly you can use Stream-Based Event Correlation (SBEC) in the OMi world.
The following are the three different types of rules you can use to correlate events in OMi:
- Repetition Rules
- Combination Rules
- Missing Recurrence Rules
To create a SBEC rule from OMi console, you can launch Stream-Based Event Correlation from Administration -> Event Processing -> Correlation -> Stream-Based Event Correlation.
Once you launch this page you can click on the yellow star and you will see three options to create new SBEC rule.
Today we will cover the Repetition Rule.
To create a Repetition Rule, click on New Repetition Rule and it will open up new window which will allow you to create new Repetition Rule.
Enter the name of Repetition Rule you want to create. (I would not check Activate rule at this point. Don't activate the rule until you are ready to test it.)
Click Next which will take you to next screen.
In this window you can create a new filter or choose existing filter you want to use for this rule.
Click on the ellipses to create new event filter.
Click on the yellow star to create new event filter. In OMi 10.12 and earlier, you will see two options—simple filter and advanced filter.
You can start with Simple Filter and then if needed you can convert it to Advanced Filter. (Note: Once you convert to Advanced Filter you cannot go back to simple filter.)
Once you click on New Simple Filter, it will open up the window which will allow you to create new filter.
Please enter a display name for the new filter you want to create.
Here you can select what criteria you want to use to filter out events.
We selected severity Minor. The title equals Test Foo message and category Test. You can click on the Additional Event Properties tab which allows you to use other attributes of events to use as filter criteria. Once you selected criteria’s then click OK to finish.
You can test the filter by clicking magnify.
Once the event filter is created, you can then select other criteria of the SBEC rule.
You can select number of events within specific time window and how you want to execute. Options include “first time’ or “every time” and how to handle subsequent events within remaining or sliding time window.
Then click next.
Now you can configure the action. You can edit attributes of same event and create a new event which you want to display in OMi event browser. Once you decide then you can click on Edit attributes which allows you to use existing attributes of event or replace it with some other value.
Once you finish this, click on OK. Then from previous window click on Finish.
Now new SBEC repetition rule is created and ready to use.
You can click on the blue circle to activate the rule. Now you can see the magic of repetition SBEC rule!
Instead of seeing many events, you will see one single event.
I hope this blog has helped you understand how to use this functionality for yourself.
