Essbase Statistics DW: How to automatically administrate Essbase using ODI (Part 9: Analyzes)


Hey guys, how are you? Continuing the Essbase Statistics DW: How to automatically administrate Essbase using ODI series (Part 9 Here), today we’ll talk about the analyzes we can do with all the data we have so far.

With all this information in our DW we can do a lot of things. We could automatically set the caches using ODI and Maxl or Esscmd but change settings in Essbase is more complicated than just an update.

We need to restart the applications, we need to take in consideration the design of each cube, we need the feeling and knowledge of the administrators, but can be done.

In fact, we can create thresholds to see if the cache is 20% off what it supposed to be and then apply the changes at night. We can also start to record the sessions (be aware that the tables get very big very quick), and analyze the retrieve/calculation times to see if the performance is getting better or not and them send a alert in case it was not after a automatic chance or something like that.

But what we can really do is provide precise information about each cube. We send a daily email for each administrator saying the actual stats for each cube, the actual setting of each cache, the recommended size, and we also send a table with more information about that application.

Attached we can add an excel with the raw data for further analysis.

This helps a lot the administrators to have a better understanding of our cubes and to decide and plan better maintenance strategies.

Of course, we can have a dashboard (and this would be the best approach) with all the statistics there showing the growing of the cube, projections, alerts of when the cubes will reach the maximum cache size, well, anything that could be needed.

The important thing here is to realize how useful this DW would be for keep our Essbase cubes healthy. And keep in mind that is a lot of other stats that can be gathered from Essbase that can do a lot for us.

For example, we can get the dimension settings and number of members and use ODI (or any language like java) to manipulate the outline and test the best Sparse/Dense settings for our cubes.

I hope you guys enjoy our series, be safe and see you soon.
