Hope you are enjoying the What’s New with vROps 6.6 series. With this post, I wanted to share a little gem of a configuration which has not been in the lime-light with all the new and cool things available with this new release of vRealize Operations 6.6.
This feature is about data retention which has not changed much since the initial days of vROps (infact it was called vCOps back then). If you remember, Time Series Data Retention is one of the key features of vROps which allows you to retain the metrics data in the FSDB for upto 10 years. This means that you can retain data without any rolls ups for months and go back in time whenever you want to.
While I have never seen a customer with a requirement of 10 year data retention, I have often come across customers who have a 2 year worth data retention policy. Specially in the healthcare or government space where historical data retention is a compliance requirement. In such cases, your storage requirement for saving all this data increases exponentially.
I have had a number of customers ask if we can purge or archive this data or even create roll ups to minimize the disk space requirements while ensuring compliance requirements of long term data retention.
This will also help with reduction of their backup and DR foot print which is key to enterprises running vRealize Operations Manager in a large scale production environment. With the release of vRealize Operations Manager 6.6, you now get a couple of options for data retention. You can find these options under the Global Settings option.
Let’s find these settings and drill down into the meaning of these:
1- Login to vRealize Operation with admin privelleges.
2- Click on Administration -> Management -> Global Settings
3- Click on the Edit icon to view the settings in edit mode.
Here you can see 2 settings:
Time Series Data Retention : This is the existing setting from the previous versions and is set to 6 months by default for 5 minutes interval data retention.
Additional Time Series Retention : This is a NEW setting with vROps 6.6. This is set to 36 months by default. This setting will ensure that after 6 months of normal retention (5 minutes), the 7th month data is rolled up into a ONE HOUR (1 Hour) roll up. You can set up this option upto 120 months for data roll ups.
With this setting in place, one can easily, setup the 5 minute interval data to 3 months which is enough for capacity predictions and performance troubleshooting and use the additional retention setting to 3 months or more based on the compliance requirements.
So go ahead, re-think your data retention policy and see how you can make the footprint of your vROps instances smaller with the benefit of longer term data retention.
More to come.. Stay Tuned!!
