VMWare V5.5 performance monitoring

Hi all,

I need to produce some performance stats for a vSphere 5.5 cluster of 6 hosts. SNMP isn't enabled so when I go to performance tab and select time range for anything such as one day or one week all I get is the current live reading for CPU, memory etc and no historical data. Anyone aware of how I can get this data and am I right that if no if SNMP isn't enabled I can't pull historical data?

Hi both,
When I select cluster node, performance tab and then advanced I get a blank screen that reads "Performance data is currently not available for this entity". And I get the same thing if I try and change the chart options to include "this week" under each of the ESXi hosts.

The only performance statistics I can see is "real Time".

This is why I asked, if performance information is being logged correctly?

if you look at a VM, do you have any history you can display, or just real time?

Anyone have any ideas? I need to report on past performance but looks like the environment has not been setup to record historical data?

And also when I log on to each individual host using vsphere client I get the same thing. I go to performance, chart options but when I select a counter the only option available to me is Real-Time, actually the option to select a date range is greyed out? . I have checked plugins and the hardware plugin is enabled.

Here is a screen shot to illustrate. I only get the days data no matter I go to the cluster or individual ESXi host.

Firstly, individual hosts will only give Real Time, this is by design, because they have no database to store the information.

The performance information is stored in the vCenter SQL Database, and Summary SQL Jobs run on the data, to give you the information, something has gone wrong with your Summary jobs.....

see these VMware Article for the fix

vCenter Server Performance Graphs only show real time data

Sorry, I made one BIG mistake. I'm working with ESXi 5.1. Sorry about that and hope it doesn't make a difference.

Hi Andrew - many thanks. Point one above is understood.

First link - The database was not migrated but still worth checking this out?

I wait to see what you say about "worth checking this out" and then speak to the SQL guy for assistance.

Andrew, just to be clear. Is performance logging turned on by default? Or could it have been turned off? I'm just trying to make sure that if I report a fault with the system that actually it isn't a fault and it is something that needs to be turned on....

Yes, logging is enabled by default always, it cannot be turned off.

You should have all the performance data, if you do not have history, only realtime there is an issue, as per articles.
