Demystifying vRealize Operations Data Collection

Around 3 years ago I wrote an article explaining the data collection process of vRealize Operations Manager. In that article, I wrote about the path followed by the data from source to destination. Fast forward 3 years and I still get questions about vROps data collection process and granularity.

People have different notions about this, so let me share the secret sauce:

vRealize Operations Manager Out of the Box, is configured to collect data every 5 (FIVE) minutes form the source. The collector wakes up every 5 minutes and gets last 15 samples of 20 seconds interval from the source.


15 Data Points X 20 Seconds = 300 Seconds ( 5 minute collection cycle)


Once the 20 samples are in, we go ahead and average them out to come up with the value which is saved in the FSDB (File System Database) of vROps. In parallel, operations such as threshold checking, computed metric calculation etc. take place.

As we all know you can further transform this data in views and super metrics by using functions such as Min, Max, Standard Deviation etc. All these functions run on the data saved in FSDB which is the 5 minute data point explained above.

These transformations are NOT ran on the 20 seconds samples. The 20 seconds samples infact are used to do calculations of the 5 minutes data points and are dropped as soon as that calculation is done. This reduces the storage requirement drastically.

Also, it is possible to change this default collection cycle from 5 minutes down to 1 minute, however it is not recommended to do that unless you understand the overall impact on Compute and Storage for increased collection and processinh.

Hope this helps!!

vRealize Operations Manager 6.6.1 Released

VMware just announced the release of vRealize Operations Manager 6.6.1. This is a maintenance release which has the minor bug fixes which were reported with vRealize Operations 6.6. If you are looking to upgrade to vRops 6.6. I would highly recommedn to move to 6.6.1 so that you can benefit from these minor bug fixes.

As per the release notes, here are the lists of issues which have been taken care off with this maintenance release:

  • The Total Reclamation Opportunity widget in the Capacity Overview dashboard now displays the correct Reclaimable Capacity metric value.

  • The VM percentage metric values for the idle, wait, system, iowait, and swapwait metrics have been corrected.

  • Issues with View rendering where resource and aggregation filtering options have both been set, has been resolved.

  • Issues with report generation for reports created in earlier versions has been resolved.

  • Improved Cluster resilience in case of packet drop spikes in the network.

  • Intermittent End Point Operations adapter install/upgrade failures has been fixed.

  • The vSAN World object shows the correct number of VMs using vSAN datastore.

  • vRealize Operations user interface displays correct information when custom attribute is updated directly in vCenter Server.

  • Imported vIDM user preserves all assigned groups.

  • Users can enter FQDN as part of the vIDM redirect URL.

  • Endless analytics restarts caused by a empty file is fixed.

  • Only vSAN enabled host are counted in the vSAN World object.

  • The issue with empty Cassandra file has been resolved.

  • Intermittent REST authentication issues has been fixed.

  • vSphere tags are no longer cleared if tag query fails.

Part 10 - VM Mobility gets a whole new meaning with Workload Balance in vROps 6.6

Hope you are enjoying the vROps 6.6 Whats's New Series. I took a little break from writing, but I am back with some more goodness around vROps 6.6. One of the key features which was shipped out in this realese is called the Workload Balance.

In my first post of this What's New Series, I wrote in brief about Fully Automated Workload Balance. Here is a quick recap of what I highlighted about this feature.

  • Fully Automated Workload Balancing:
    • Ensures performance across the datacenter's with fully automated workload balancing, across clusters and across data stores.
    • Ensures DRS Configurations and provides the option to set DRS automation level for individual objects.
    • Predictive DRS takes action to preempt resource contention.
    • Utilizes operations analytics to optimize initial placement of workloads through vRealize Automation.

In the upcoming vROps Webinar Series, I will go deep into this topic to explain how vROps Workload Balance can help you proactively avoid performance problem by using the Mobility Aspects of a VM with time trusted technologies such as vMotion and Storage vMotion.

Apart from being proactive on moving virtual machines across clusters, Workload Balance also helps you track the configuration of DRS which plays a big role in moving virtual machines within the cluster.

With Custom Datacenters (a construct of vRealize Operations Manager), you can create your mini datacenters of your favorite clusters with like properties and move virtual machines between these clusters to avoid any performance bottlenecks and effectively utilize the capacity.

Watch out for the announcement for the next webinar episode where we will see all this goodness in action.

In the mean-time, see this video from Matt Bradford who works as a Technical Account Manager at VMware and also runs a wonderful blog named vmspot.com 

Matt explains both Workload Balance and Predictive DRS with some great examples. See him in action below:
