No Data displayed in vCops

I am using vCenter Operations for a approx. 2-3 weeks on one of our lab environments, however I am not sure when it started, but most metrics are now saying: No Data

I have attached a screenshot showing what I mean.

Anybody able to give me an idea on why this fails? In the beginning we had data in!

Hello.

Verify that the timezone information is consistent on the vCenter Operations appliance and the vCenter Server.

Good Luck!

Hi,

sorry to say, I checked it and both vCenter as well as vCops and CapIQ as all others are set to Europe/Berlin. I also checked the time and it is in sync.

Any further idea?

Thanks

Just curious.  How many VMs do you have managed by vC Ops?

There are only 46 VMs, as said this is a demo/lab center, so should be fine.

It ran also fine in the beginning, must have stopped at one point, not sure when, just saw it yesterday when trying to demonstrate it to a customer...

ysandfort,

Was the vCenter Operations virtual appliance configured with DHCP? Has the lease expired on the IP address and now the virtual appliance has a different IP address?

Did you check if the following was applicable?

Hi James,

the box has a static IP address. We did some analysis and found out that data is displayed once you restart the vcops appliance. We will check this now every few hours and see if we can figure out when it stops to present data...

It is weird...

Could it be that vcops appliance needs a restart after a vcenter restart?

Thanks

ysandfort,

Is there anything in your 46 VM environment that you might think is atypical?

Examples:

1) Each VM has many virtual disks (e.g. > 5) that span many datastores;

2) There is a high rate of VMotion activity (high number of VMotions in a relatively short period of time) perhaps caused by DPM/DRS and the likes;

3) There is a high rate of creation and destruction of VMs (high number of creation/deletion in a relatively short period of time);

4) There is a high rate of power-on/power-off activity;

What about memory usage within the vCenter Operations virtual appliance? Does the guest OS have enough free memory? What about free disk space? Do we have any disk I/O bottlenecks?

Hi James,

nothing very abnormal...

1) Only 2 VMs which have 3 or more disks and they are on 2 datastores, but have low IO

2) Nothing abnormal, below 20 per day

3) No big create/destruct going on

4) Nothing big here either.

The Host has enough memory, memory usage on Appliance is low, active memory is below 1 GB. Configuration is default.

It has a dedicated LUN on a Clariion, which is as of cap iq low used...

Any further ideas?

Hi,

we are also experiencing these issues: Each time the vCenter service restarts vCenter Ops will stop collecting data (until you restart the vCenter Ops service or the whole appliance).

We currently have this under investigations with VMware support. If there are any results I will post them here.
