vROps summary view of OS per vCenter and Cluster and the same for VMware Tools

February 6, 2018, 5:49 pm

Hi, I need a View in vRealize Operations Manager that shows me how many VMs of each operating system are in each vCenter, and inside each vCenter, divided per Cluster.

I imagine something like: On the left lines, the OS names. On the top of the columns, the names of the clusters. And inside each cell, the number of VMs that has that OS and belong to that cluster.

 

And I also need the exact same report but for VMware Tools.

 

I could not find the way of creating the correct super metric for it.

 

Any suggestion will be really apreciated!

Best regards

i cannot find any info on this question i was asked but my guess is that it's possible if there is a 'remote collector adapter' supported by VMware.

Identify VMs with increased disk usage

March 6, 2018, 10:01 am

I'm looking for suggestion on how to identify VMs in a cluster that have increased disk usage during a specific time frame.  The situation is that the ESXi cluster is served by a single array with over 1000 VMs in the cluster. That array has performance issues every week or so. There isn't a single or group of VM's that I can find which is causing a higher usage on the array that would cause the performance issues.  I'm looking for ideas on how to get a list of VM's in a two hour window that have increased their disk usage by a specified ammount. Or even better would be giving the standard deviation for the VMs. I have some limitations due to the vRops environment being licensed at standard.

Monitor connection between vROps and vCenter servers

Hi all,

 

 

After an issue we had a few weeks ago, VMware noticed this from the logs:

2018-01-24 10:37:42,038 ERROR [VMVI RetrieverThread Datacenter Watcher:1]  (82850) com.vmware.vcops.vlsi.VcSessions.terminateSession - Unable to logout from VC

   faultCause = null,

   faultMessage = null,

   object = ManagedObjectReference: type = Folder, value = group-d1, serverGuid = null,

   privilegeId = System.View

 

.....

And further down, it looks like it tried to reconnect but could not:

2018-01-24 10:37:42,038 WARN  [VMVI RetrieverThread Datacenter Watcher:1]  com.vmware.vim.vmomi.client.http.impl.HttpConfigurationCompilerBase$ConnectionMonitorThreadBase.shutdown - Shutting down the connection monitor.

   faultCause = null,

   faultMessage = null,

   privilegeId = System.View

 

 

I was informed this was a disconnect between vROps and the vCenter server.

 

 

Question:

I wanted to ask if there was any type of monitoring that I could create when vROps loses connection to a vCenter server?

How can I monitor for the disconnect?

     - By a specific alert

     - By a port disconnect

     - By a ping/SNMP trap?

 

 

Thanks for any and all help!

Old Data Receiving

Hi all,

 

I have a Large 6.6.1 cluster. We have 5 Master/Data nodes and 4 Remote Collectors. There are 4 vCenter adapters and 1 vSAN adapter.

I switched from the MPSD to the vSAN adapter this past Monday. I have removed the old MPSD adapter and have confirmed the objects it monitored have been removed as well.

 

Since switching over to the vSAN adapter, I have noticed that pretty much all of the objects in that instance have a collection status of "Old Data Receiving". Some objects are collecting, some have old data. I know the "Old Data Receiving" means data is not current and it is behind by 5 polling cycles.

 

 

My questions:

- Does this status simply mean there is no new data?

- Should I be concerned with not receiving actual data to trigger the alerts?

 

 

Thanks for any and all help!

"Error synchronizing user privilege information with VMware Virtual Center instance"

Hi All.

 

I'm in the middle of doing a vSphere Optimisation Assessment (VOA) for a customer and had a weird problem today. I started to notice intermittent health issues with the vROps server itself. An error would appear occasionally saying "Error synchronizing user privilege information with VMware Virtual Center instance". Sometimes the problem was resolving itself after about 15 minutes but sometimes it would last for hours. It happened while I was onsite today so I had a look at the recommendations for the alert. That suggested that I should look at the setup of the vCenter Server connection.

 

I went to the settings for the vCenter adapter and clicked on the test button to check the credentials I was using. The first time I clicked the test failed. The second time the test was successful. But now the adapter stopped collecting. Eventually the appliance stopped responding entirely and wouldn't even respond to pings.

 

I jumped onto the console of the vROps appliance and saw this error message "Authentication token is no longer valid; new one required". At this stage I decided that the only option was to restart the appliance.

 

Has anyone seen this sort of problem before? I've attached a couple of screen shots.

 

Cheers,

Neil.

Custom Dashboard: use a view as source for widget interaction

Hi

 

I want to create a new dashboard with a view as datasource for another widget, which is an object list. My view has a list of vSphere datastores with columns for write/read latency and so on. My idea is to click on one of these datastores in this view and then all VMs of this datastore should appear in the second widget (objectlist). I can't choose the view as a source in the widget interaction tab and I don't understand why. What do I have to do, to get a view as a datasource for another widget. The view widget is "Self Provider" in my case, and the object list should be "children", or am I wrong?

 

thx

Alert vs Symptom Wait Cycles

When creating symptom definitions, an advanced setting is given to change the Wait and Cancel cycle.  However when creating alert definitions, there is also a configuration field to set the Wait and Cancel cycles.  I'm a little confused with which one I should set.  If I set a Wait Cycle of 3 for the symptom and a Wait Cycle of 2 for the alert, does that mean I need to wait 30 minutes of seeing the symptom (3 symptom wait cycles x 5 minutes x 2 alert wait cycles) before seeing an alert?

We have deployed new 6.6.1 vrops and the latest version of vRLI as part of our 6.0 windows to 6.5 vcsa migration and we were looking into deploying vidm so that we get SSO between vrops and vrli but when i look at adding users i dont see the vidm listed when adding a user in the access control after i configure vidm in authentication sources in vrops

 

How do you grant access to vrops for vidm users? Am i being stupid?

Problem with Disabling Default Policy Alerts & Setting up New Cascading Policy & Alerts

February 27, 2018, 8:15 am

I've setup a couple new policies and I'm not getting very far with the inheritance / priorities.  It's setup (as below) the way I thought it was supposed to work, yet my Alerts keep firing.

 

My objective here is to turn off ALL Default Alerts, except one new User Defined Alert (Datastore Cluster Capacity Alert), and then block that new alert on a few specific objects defined in a custom group.  I'm attempting to leave the Alerts as defined in the "vSphere Solution's Default Policy" completely alone (ie, enabled/defaults).

 

So I created a new "COMPANY - Default Policy with Custom Baseline Alerts" where that used the Solution's Default as its base.  I disabled all but this one alert (Datastore Cluster Capacity Alert) and applied this policy to the "Product Licensed" default group.

From there I created another new "COMPANY - Default Policy Alert Override for X Datacenter" using the "COMPANY - Default Policy with Custom Baseline Alerts" as my base for this new Policy and I disabled the (Datastore Cluster Capacity Alert), and lastly applied this policy to a Custom Group that has the Datastore Clusters I wish to exclude from the alert.

 

The Policy Priorities are:

1 - COMPANY - Default Policy Alert Override for X Datacenter

2 - COMPANY - Default Policy with Custom Baseline Alerts

D - vSphere Solution's Default Policy

 

I'm able to validate the various objects all now show defined by #2 above except for the Datastore Clusters I want excluded via my group.  Those properly show the #1 policy above.  So everything LOOKS right, YET I'm still getting all the alerts!  Very frustrating.

 

Any ideas?

Hello,

I have a problem with one of my super metric. I tried to count all hosts in cluster which have active hypertreading.

So, On every host we have properties: adaptertype=VMWARE, objecttype=HostSystem, attribute=config|hyperThread|active

So i tried to build metric with look like:

${adaptertype=VMWARE, objecttype=HostSystem, attribute=config|hyperThread|active, depth=2,where = "==true"}

 

But "where" clause has problem with "true" statement. Is there any other possibilities to count ESXi hosts with HT active ?

previous vrops versions did not so using esxi shell or powercli was best methods

 

it's interesting that the original version of the old vkernel tool which i had licensed for enterprise use in 2009 provided zombie info so i'm surprised that i've heard vROps does not do that?

Hi Team,

We are working on one solution where we are supposed to fetch all the alert details and summary specific to input Alert ID.

we are getting all the alert details via /api/alerts/{id}. But not able to find any api to fetch the symptoms associated with alertID.

Stress - Analysys window for interactive/batch workloads

March 9, 2018, 4:05 am

Hello!

 

I am on a path of understanding really well vRealize Operations so I can make better use of the solution. In my studies I realized that the Stress badge is really important as it is used to calculate capacity/time remaining and all of those recommendations for oversized/undersized virtual machines.

 

So, out-of-the-box, the stress is calculated by looking for the worst hour in a 30 day window. So the analysys windows is one hour. If we change this window to a bigger size, we get a more normalized average (and maybe a lower score badge).

 

What I'm having trouble understanding is why an interactive workload (so, pretty constant but it may have spikes if there is too much requests) would require a one hour analysys windows and a batck workload would require a bigger window, let's say, 240 minutes windows.

 

Can someone explain to me the relation between type of workload and the size of analysys window?

 

Thanks!!

The screenshoot below indicates that I'm you if memory. But I dont get it. If I look at the numbers it says that only 84,35% or 1,33TB memory of the usable capacity of 1,57TB used. Then why is it red ? Is it a bug or am I missing something ?

Clone Alert: Fully-automated DRS-enabled cluster has CPU contention caused by less than half of the virtual machines

Hi all,

 

We have been receiving this alert on some of the DRS-enabled clusters. We want to be alerted when we have an Immediate/Critical issue. I have tried to clone the above Alert and remove the Warning symptoms for each symptom set. I am receiving an error when trying to clone the alert. I have tried to clone it first, before removing the Warning symptoms, still does not work.

We are using a standard license and should be able to clone/create new alerts.

 

I am not able to set the symptoms in the policy to Disabled, it keeps forcing the symptoms back to Enabled. I cannot negate the symptoms in the original alert, nor do I want to, as it will reset OOB definitions when I next upgrade.

 

Is anyone able to successfully clone the above alert and remove just the Warning symptoms? Is there anyway to accomplish this?

 

Alert:  Fully-automated DRS-enabled cluster has CPU contention caused by less than half of the virtual machines

 

EDIT: I am using the admin when I try to clone the alert. I have also tried to create the alert from scratch, but that does not seem to work. I have also been able to create the alert without the DRS symptom set, but this would not help me as I want to see the Immediate/Critical alerts for a DRS-enabled cluster.

 

 

 

 

Thanks!

"Not Exiting" objects and alerts not showing

March 11, 2018, 10:52 am

We had an issue with a host losing connectivity to the vCenter server over this weekend. I have confirmed the host was removed and re-added within vCenter.

When looking in vROps, I am seeing 2 objects for the host and 2 objects for the local datastore. One set of objects are set to "Not Exisiting" due to the removal of the host from vCenter. The other set is collecting/receiving metrics. I believe this is the correct process for vROps as it no longer saw the original object and removed it, then created a new object when it saw it in vCenter.

 

When I try and view the alerts to see if we received the "Host has lost connection to vCenter" alert, I am not able to as this object is "Not Existing". All I can see for this object are the metrics, which does not tell me if we did or did not receive that alert.

 

We have our Global settings set to retain deleted objects for 72 hours, the Object History for 300 days, and Symptoms/Alerts for 90 days.

I have been playing around with the API/PowerCli commands, but I am no expert, far from it.

I have been using Postman to try some of the API commands out, but I am not find the exact command to retrieve this information. I have also been looking/reviewing some blogs from:

http://vman.ch/

https://docs.vmware.com/en/vRealize-Operations-Manager/6.6/vrealize-operations-manager-66-api-guide.pdf

Straight-Up Flying with the vRealize Operations REST API - VMware Cloud Management

But I have been able find anything definitive, possibly due my lack of skills with API/PowerCLI.

 

Question: Is there a way to pull this information via the API/PowerCLI commands to see if we did receive that alert for that host object? Anyway to get historical data of a "Not Existing" object in vROps? Surely there should be something available that can aid me in this process?

We are using a Standard license, so I am unable to create a report, and not sure if I can create a report for an object that is "Not Existing".
