Network Interface Connectivity Representation

Dear All,

Why the connectivity representing 0% while you can see a lot of traffic on the interface?

Hi @Babar Q.

Its look like all your connections are being refused.

Check also the Quality tab.

Hello @Yos N.

From where to where connections refused, because there is no issue with the monitoring?

Go to connectivity from process perspective of this host

Hello @Yos N.

My question is different than this. Have a look at the below screenshot. Its a 4 hosts group, 2 are showing 0% connectivity and the other 2 are showing 100% connetivity while the traffic is almost similar.

Let's try to check first what causing those hosts to show 0% connectivity by checking the processes connectivity.

Can you please show the connectivity of the processes of one of the hosts with 0% connectivity, sort the processes by the connectivity to see which of the processes are refusing connection ...

And also take a look a this thread which explain what is the meaning of Host connectivity metric.

Hello @Yos N.

Than you for sharing the thread.

The below host showing 0% connectivity while you can see that maximum retransmission is 0.85% for one of the following processes, but the connectivity is 100%.

The host which is showing 100% connectivity has a maximum retransmission of 0.93% for one of the processes.

HI @Babar Q.

So its look like your application processes are connected OK, that the good part. Are there other processes down under the list of processes?

Hello @Yos N.

As I shared earlier that everything is similar among 0% connectivity and 100% connectivity hosts.

Ammm its look like the blame here is on Host connections good question for dynatrace one I think

Hello @Yos N.

Yes. It seems time to go to Dynatrace ONE/or Support to understand such type of cases.
