Veeam One doesn't display data at intervals

[adiaz]

Hi everyone,

I'm a Technical Consultant and I usually install Veeam Backup and Replication to customers. In a lot of cases I have an issue (not an error) when I try to monitor with Veeam One. In the Infrastructure View, when I select a host to see, for example, CPU usage, and I change the period of monitoring, I can see intervals where there is no data, so the line of the chart is cut across that period and continues later.

So, there are some periods that no data is available, and customers ask why. What is the reason of this, and how could I fix it?

Thank you very much.

Antonio,

If you see gaps in historical monitoring period, then it means that there were issues with collecting data at that time and you should have received an alert on this.

How often do you see this situation? Is it specific to some platform (Hyper-V/vSphere)?

Thanks!

Hi Antonio and welcome to the forums!
Once you install Veeam ONE, give it some time to download historical data to show. It can take time depending on the infrastructure size.
Another possible reason is a lack of data or if the host was powered-off/disconnected.
Do you experience it just after the installation?
Thanks!

Hi again,

Thank you very much for your replies and for your warm welcome.

If you see gaps in historical monitoring period, then it means that there were issues with collecting data at that time and you should have received an alert on this.

Vitaliy S., as you say, there are some gaps without data available, and more over here in my office I usually receive some alarms about data collection failure (here the network fails very often), but I have no evidence that my customers also have those alarms, because I usually receive their Veeam One notifications and there is no trace of this kind of alarms.

How often do you see this situation? Is it specific to some platform (Hyper-V/vSphere)?

I always see this issue when I change the visualization period from past hour to past week, for example. And we just work with Hyper-V, so I don't know if vSphere platform has also this issue.

Sherstakov, unfortunately I was not the technical who installed Veeam One in those places. And those hosts work 24/7, so probably hosts have been powered-on along the whole period. However, thanks to your comments I tend to think that it's a data collection issue with the network, despite not having received alarms (or not having had evidence of them).

So the next step I'm goint to do is to verify that the data collection across the network is correct, and then I will tell you the veredict.

Thank you very much!

Indeed, in a case of connection failure you should get Performance data collection failure alarm.

I always see this issue when I change the visualization period from past hour to past week, for example. And we just work with Hyper-V, so I don't know if vSphere platform has also this issue.

Have you tried to generate a report for with the same interval and performance used? So we can find out if it`s Monitor or common problem.
Thanks.

Hi again to everybody,

I've been delving a little and definitely I often get Performance Data Collection Failure alarms, but until now I have not been able to see them because the technician who installed Veeam disabled them. So probably it's a data collection issue, but I don't know how to fix it.

On the other hand I've tried to generate a report from Veeam One, but the option to generate them doesn't work (it launches a browser with a web page that shows error 404).

Thank you very much to everybody.

That`s not a good practice to disable alarm if you can`t resolve it. There is Knowledge Base for each alarm with the issue description and resolution steps. If you or customer can`t resolve it, it`s highly recommended to contact technical support team.

Do you generate it from Veeam ONE Monitor or Reporter? What is the name of the report?
Thanks!

All right, I'll look for information about this alarm and how to resolve it.

I have tried to generate reports from Veeam ONE, I've never tried with Reporter, is it worth?

Thanks a lot again.

[Shestakov]

Veeam ONE consists of 3 parts: Monitor, Reporter and Business View. That`s why it`s called ONE, by the way, historically these were separate products
Looks like you generate the reports from Monitor. Try to start Veeam ONE Reporter and generate reports there.
I`m still curious what kind of report gave you error 404, they should work wherever you generate them from.
Thanks!

[adiaz]

Well, after fighting hard against Veeam One, I have found out that the reason why Veeam One Monitor gave me a 404 error was that it was not able to connect neither Reporter nor database. I have fixed it by checking credentials in Veeam ONE Settings. Now, reports work ok in Veeam ONE and also in ONE Report. So, now I have both tools working thank to all of you, thank you very much!

On the other hand, both reports, those generated by ONE Monitor and those generated by ONE Reporter, show gaps on lines where supposedly there is no info available. In this way we may think that this is not a reporter problem, but a collection data problem.

So, what may be the process to find out how to resolve this issue? Customers is pressing me more and more with this matter.

Thanks a lot, seriously!

[Vitaliy S.]

If there are gaps in performance graphs, then indeed there was a data collection problem. To confirm that, please review internal alarms on the Veeam ONE Monitor Server, you should see something similar to this "Performance data collection failure" in the list of triggered alarms. The best thing to do in this case is to monitor this alarm and when it happens try to resolve connection issues. Hope this helps!

[Shestakov]

By the way, do you have these performance gaps for ESX(i) or Hyper-V hypervisor?
Thanks!

[adiaz]

Hyper-V, all of them.

The best thing to do in this case is to monitor this alarm and when it happens try to resolve connection issues

All right, I will monitor that alarm and then I will tell you.

Thank you very much again!

[Shestakov]

That`s interesting. Could you describe the issue a bit?
Do you have Veeam ONE server installed on a VM running on the hypervisor which has the performance gaps?
Does it miss particular metrics or all the performance?
Thanks!

[adiaz]

That`s interesting. Could you describe the issue a bit?

Of course, please look at the following screenshot of Veeam One with gaps:



Moreover and as all of you said, at the top of the screen there is a "Configuration issue" that tells there is a Backup performance data collection failure.

Do you have Veeam ONE server installed on a VM running on the hypervisor which has the performance gaps?

In this case, Veeam Backup and Veeam ONE are installed in a physical machine that runs some Hyper-V virtual machines (it's not a dedicated virtual machine to run Veeam, as we usually do), but there are two more servers that also run Hyper-V machines and also have the performance data collection issue.

Does it miss particular metrics or all the performance?

Gaps appear in all of metrics that Veeam ONE Monitor can show on every machine, i.g. CPU, Memory, Network, Disk, but all of them in the same intervals.

Thanks a lot

[Shestakov]

Thanks for the comprehensive reply, Antonio.

If the gaps are caused by the performance collection failure, that`s expected.
I was curious if there were any gaps unrelated to those issues, in that case further investigation is needed.
But since it was caused by issues which are already fixed, we are good.

Let me know if any assistance is required in future.

[adiaz]

I was curious if there were any gaps unrelated to those issues, in that case further investigation is needed.

Exactly, I think we need further investigation, specially because a lot of customers have this issue, and all of them receive the performance data collection alarm. In fact, the screenshot I uploaded in my previous post is just one of many. However, the other services in the network work perfectly, and I would have been warned if not.

So, could it be a Veeam ONE issue? Evidence suggests so.

Thanks a lot again.

[Shestakov]

I see, so the best you can do is to contact Veeam support for detailed logs review etc.

Troubleshooting you can do in such cases when the performance data is absent with no Veeam ONE alarm is:
1. Check if metrics exist on the Hyper-V host running Perfmon tool.
2. Open perfmon tool on the machine where Veeam ONE installed, connect to the Hyper-V host from perfomon and review if it shows the desired performance.

If the performance is shown in both cases, but not in Veeam ONE Monitor, that`s probably Veeam ONE issue, otherwise it`s Hyper-V(step 1) or network issue(step 2)
Thanks!
