Specific Alert Notification in vROPS

As many times this question is asked "Is it possible to get the notification only for specific alert/alerts". My answer is YES for this. Then how one can achieve this. Let me explain this in the following screenshots

1. Log in to your vROPS console > Open the Content Page > Click on Notifications > Click on the Green Plus sign from the right hand side panel to create the new notification rule.

2. Select the appropriate options as per you rule requirement and select the specific alert as i selected in the below given screenshot > Click on save.
Note: Screenshot that i shared here is not the perfect rule as you notice some error. So what i just want to show here that you can achieve this with notification rule in vROPS.

This is how you can only configure the notification for the specific alert/alerts.

Patch for these Known Issue of vROPS in 6.1

The following issues are known to occur on VMware vRealize Operations Manager 6.1.
  • The object type that is returned from the MethodInstances parameter value is different from earlier versions.
  • Outbound SNMP messages do not contain alert messages when events are alerted via SNMP traps.
  • Upgrade from vRealize Operations Manager 6.0.x to 6.1 fails with the following error: Cluster offline: PAK install failed.
  • Dashboards do not display when the cluster is restarted.
  • A null point exception occurs when you stop the collection of an object.
  • Log Insight 3.0 cannot send alerts to a version of vRealize Operations Manager that is upgraded to 6.1.
  • When new alert notifications are created with a filter, no new alerts are sent out even though new alerts exist. Only canceled alerts are sent out.
  • When you configure outbound plug-ins, a null point exception occurs for instance level metrics.
  • If the description in an alert definition is empty, it results in an error from SNMP messages. This occurs in the Hyperic adapter.
To resolve these issues Public Patch is available. Download this patch from here. Patch name is vRealize_Operations_Manager-cluster type-6.1.0.3294016.pak

Deprecated VMFS volume(s) found on the host. Please consider upgrading volume(s) to the latest version in vSphere 6.0

Issue :- Deprecated VMFS volume(s) found on the host. Please consider upgrading volume(s) to the latest version
Reason :- This is known Issue in vSphere 6.0. This issue occurs because the version of the filesystem is not known during the initial detection. Therefore, comparing it against the list of valid filesystems does not return a match.
 
Solution :- Currently there is no solution.


Workaround:- Restart the Management Agents of the affected ESXi hosts to clear the Warning

Source: VMware KB 2109735

How to findout all the unregistered VM's in a specific ESXi Host?

1. First Connect with ESXi Shell (Local or Remote) Let's assume hostname of esxi is ESXi-a-01
2. Then execute this command to findout all the .vmx files visible to particular esxi host example :- ESXi-a-01
find -iname \*.vmx 

3. Then execute  another command to list all the running vm's on the esxi host example :- ESXi-a-01
vim-cmd vmsvc/getallvms
4. Now compare both the outputs and you will get the info what all the vms are not registered on this ESXi. Now as you can see in this example Linux-a-02, Linux-a-07, Linux-a-09, Linux-a-010 are not registered on this esxi host.


How to Findout the UUID of all the VMs

Today someone asked me that how to find out the UUID of all the VM's. I thought i should share it with everyone. Here is command to find out this detail:-

Changes in vSphere 6.0 Logs details as compared to vSphere 5.x

In vSphere 6.0 any action perform against the ESXi hosts from vCenter Server listed as [user=vpxuser:DOMAIN\user]as given in the screenshot:-
In vSphere 5.5 any action perform against the ESXi hosts from vCenter Server listed as [user=vpxuser] as given in the screenshot:-

What should i do after changing the Logging Level in vCenter?

Everyone knows in vCenter we can change the logging level from Info to Trivia or Verbose for the troubleshooting purpose. But the question that is asked to me "I enabled Trivia or Verbose but i am not getting detailed info in the log messages"

Answer = Restart the vCenter Server Service after each change made in the logging level Settings

These are the logging levels we have in VMware vCenter:-


Note:- VMware recommendation is to enable the trivia or verbose only when you are doing troubleshooting. Once troubleshooting is done, revert it back to the default settings. Don't keep it enabled in the production environment.

User Interfaces in vROPS (vRealize Operations Manager)

vROPS provides two interfaces:-
1. Administration Interface
2. Product User Interface
In the Diagram that is given below both are interfaces are explained and where we can use these interfaces

What is vROPS a.k.a vCOPS?

vRealize Operations Manager (vROPS) a.k.a vCenter Operations Manager (vCOPS) is provides visibility and insights in to Capacity, Performance & Health of your environments.

Benefits of vROPS:-

1. Cloud Operations Console = It is console from where you can do the centralized management of your environment.

2. Less Administration overhead to investigate and resolve issues = It can reduce the administration overhead that is needed to investigate and resolving the issues by providing the recommendations and sometimes can provide the action button to apply those recommendations.

3. Predicitive Capacity Modeling = you can visualize changes and even schedule the prospective changes in your environent with it.

4. Integrated Compliance = Once vSphere solution is integrated with vROPS it provides the hardening guide with vSphere solution as well and due to this auto integration of hardening guide it can generate alert symptoms. Although you can create custom symptoms as well.

5. Better Operations Visibility = Once vSphere Solution or any other solution is integrated with vROPS, it provides the visibility across all the layers of the infrastructure in the form of Health, Risk and Efficiency category.

6. Management Pack for All Domains = It provides management pack for all the domains like Cloud, Virtual, Application, Storage, Networking etc. For more info you can refer https://solutionexchange.vmware.com. Management Pack is the way of integrating a solution with vROPS.

In the upcoming blog posts i will try to give more info about these features. Stay tuned for the more updates.
