What does Network IO time mean?

Hi,
We encountered problem with our application. During investigation we've seen long "Network IO" time.

What this time exactly means?

Thanks

Network Input/Output is essentially just time attributed to sending data between monitored processes. If it's a slow network, there's large data transfers, or it's very talkative that can be high. I'd look at some individual PurePaths to see exactly where all of that time is spent.

Also keep in mind that the network i/o split comes from calls to specific packages/classes/methods like for example calls in the java.net/java.nio

Hi all,

Just want to double-confirm my hypothesis:

Can I say that the 'network-IO-time' in Dynatrace is the same/analogous to 'IO-time' in AppMon?
