There is no doubt that vRealize Operations Manager (vROps) is a very powerful tool that helps you with monitoring, troubleshooting, and planning your datacenter workloads and components. You can find a lot of blog posts, webcasts, presentations, and recordings on how the product can be used because it benefits both worlds—both technical folks and the management layers of the organization. vROps provides high-level dashboards, details on specific objects, the history, and trends.
In my experience, the customers who get the most out of a product are the ones who have vROps dashboards displayed on big TV screens inside their IT staff areas where they can view the current health status of their environment. Then as soon as the dashboard turns yellow or red, they can jump in to start a troubleshooting analysis and investigate the reasons for the “not-so-green” dashboard on their workstations.
There is another group of customers who rolls out vROps to collect data and never return to it unless a problem is reported. Even though it’s not the ideal scenario, it’s a common and understandable way of using the product. What has happened a few times during my years as a VMware TAM, however, is that when vROps runs a high number of statistics for a while, metrics and analytics can fill up the product internal database. So when you’re having a bad day in the datacenter, or your manager asks when new hardware needs to be ordered to increase your datacenter capacity—you go back to vROps only to discover that no data has been collected for the past few days or even weeks, and therefore you don’t have an answer!
After discussing this recurring problem, I received guidance from my colleagues: Oleg Ulyanov, VMware Senior Consultant, and Frank Escaros-Buechsel, VMware Solution Architect. After putting together all of this information, they developed a recommendation that enables VMware customers to avoid situations when running out of space goes unnoticed. This solution adds storage capacity to the vROps appliance before it runs out of room to collect more data.
We recommend that you do the following:
• During deployment, properly size your vROps appliance based on the number of objects you will be monitoring. The details on how to do this are located at: https://kb.vmware.com/kb/2093783?src=vmw_so_vex_pmcas_1152
• Make sure you know how to add space to your appliance: https://kb.vmware.com/kb/2016022?src=vmw_so_vex_pmcas_1152
Also, check the vROps documentation at: http://pubs.vmware.com/vrealizeoperationsmanager
• Create a vROps Alert Notification based on pre-defined Alert that is called,“Fsdb is estimated to run out of disk space soon”. View it by going to the Alert Definitions screen:
Also check that the Alert is enabled in the default policy, and that the policy is applied to the fsdb object.
• Now create the Notification Rule by accessing the follow documentation: https://pubs.vmware.com/vrealizeoperationsmanager- 6/index.jsp?topic=%2Fcom.vmware.vcom.core.doc%2FGUID-AE26F747-EBC7-44DE-BACB- 6B0B8593546C.html?src=vmw_so_vex_pmcas_1152
• Then, navigate to Content > Notifications:
As you can see, we selected all the parameters that we’d like the Notification Rule to follow according to our organizational policies—such as who receives the alert, how many times we need to be reminded, etc. Also, the Alert Definition described previously is specified here as the Notification Trigger.
We hope this blog post will save VMware customers from discovering that the environment data is not collected because the vROps database has run out of space.
One more thing:
Please look at VMware Hand-on Labs (HOLs), which are FREE of charge: http://labs.hol.vmware.com/?src=vmw_so_vex_pmcas_1152
Search for vRealize Operations Manager—you will find multiple labs covering basic and advanced topics. Also, you should look in specific use cases covered by HOLs that might match your current needs. The screenshots for this article were created in an HOL environment!
