I have gone through couple of forums and articles to identify these thresholds, could someone please advise if this can be used as a general best practice, leaving out the business requirement whether it is business critical workloads or not.
Please view the attached spreadsheet for the metrics.
Hopefully this helps.
I am still wondering are there official VMware documentation to advise the thresholds for these parameters.
I have gone across performance troubleshooting, performance best pratices documentation but finidng it hard to find the thresholds as a good advise from vmware.
The best I've seen is the Performance Troubleshooting Guide. Its last iteration was for vSphere 4.1, but it is largely still accurate, particularly the mentioned thresholds. Anything you do not find in that guide (or that deviates from the guide) is found by personal experience or amongst the blogs of the many VMware experts out there.
Thank you, i was doing that only and have found all these thresholds. It would be good to have a documentation from VMware outlining these thresholds as best practices.
Cheers and i think this is going to be a dead thread after this.....was really keen to get some pointers from the community.....
All your network and disk values are worthless without an understanding of the application's requirements.
Most many of the DBs I work with, anything over 2ms disk response time is catastrophic. For some of the big data ones, anything under 30ms is basically unachieveable. I might as well suggest that every speed limit in the country should be 35 MPH, without regard to the nature of the road.
Also, it doesn't make sense to measure IO in KBps with a critical value of '75%'.
