ESXi 5.1 View Percentage of Reads / Writes on the Datastore

Do the performance charts have the ability to list the percentage of reads and writes per datastore?

I noted all of my performance charts of any of my 100+ datastores are listed as No Data Available and believe this relies on a SQL job to pull the information correct?

Averages and Summations of datastores metrics are generally what is available in realtime.

For data recorded, highest latency and average usage is recorded in the summaries.

1) Open VIClient to connect to vCenter
2) Change to the Datastore View
3) Select a datastore and click the performance tab
4) from the drop down menu change it to performance... and nothing

we have real time statistics...and when we click day, week, month...

Data is not collected for the current statistics level. Increase the statistics level to view the graphs.

I know were are running 5.1 GA and planning to upgrade to 6.0 very soon hopefully this will fix it. Also performance charts on host and Vm works just fine and seems to only be an issue if you view the performance chart on a datastore

ANything I can do in the mean time

Sometimes, reports can timeout, we've have seen this on under resourced SQL servers.

The data will be resident in the SQL tables, if you have the skills to extract the data.

but back to the original question, they will only show the data for the datastores, by design, and not by your specific % read and % write requirements.

The lack of data being returned highlights another issues.

Thank you for your insight as always.. I know I have problems with vcenter and it needs some TLC and hope things will improve a bit with housekeeping and upgrade to 6.0 update 1 when it is out.

Think carefully about your design, with vCenter Server 6.0 and standalone Plarform Service Controller, or installed with vCenter Server.

and also whether you want to create new install or update the existing database. (and carry the issues!)
