vCOPS: Empty Dashboard after the upgrade to version 5.6


After the upgrade of vCenter Operations 5.0.3 (vAPP) to vCenter Operations 5.6 I got an empty screen when I started the vCenter Operations Manager website and the Dashboard view:

So I started to troubleshoot and a Goolge search. When I found the following thread on the VMware communities: http://communities.vmware.com/message/2158059. The fix is really easy. Just clear your browser cache and after that, the Dashboard view will work again.

vCenter Operations: Disable the default web timeout


Just a quick note to remember how to disable the default web timeout of 30 minutes in vCenter Operations.

  1. Login as root on the UI VM.
  2. Open the the web.xml file with VI: vi/usr/lib/vmware-vcops/tomcat/webapps/vcops-vsphere/WEB-INF/web.xml
  3. Change the default value 30 to –1 to disable the timeout completely.

  5. Save the changes via ESC, :wq
  6. restart the vcopsweb service via:  service vcopsweb restart
  7. Wait until the service is ready again.

Login to vCenter Operations and enjoy the view of your dashboards Smile

So I checked if the services where running at the time. You can do this with the vcops-admin status command:

The next thing to check is the free disk space with the df –h command:

The disk seems to be full. To fix this issue, You can follow the steps from KB2016645:

To add a new virtual disk to the virtual machine:

  1. Power off the vApp.
  2. In the vSphere Client, right-click the virtual machine and click Edit Settings.
  3. Add the additional virtual disk.
    Note: Ensure to consider the future growth while selecting the disk size.
  4. Power on the vApp. The virtual machine automatically configures the newly added disk at boot time.

When the VM starts the disk is added to the VM and the LVM logical group will be configured with the new disk:
