DNS errors number

Hello,

Where does Dynatrace get the 80% errors from, sometimes this number changes per minute?

From the network monitoring module and does it by network packet capture.

Hi Julius,

Sorry about  the unclear question, my mistake. I should have asked something like how is this number calculated , or something like that...

Thanks for your fast reply!

Further to what Julius already mentioned, the value seen on the tab, is the last captured value, meaning if you see 80%, that's the last seen value - it is not an average or similar across the timeframe.

To my knowledge, the % is calculated based on the total nr of DNS queries, divided by the nr of errors/failures. Hence: if you had 5 queries, and 4 resulted in NXDomain(3) errors, that's 80% errors.
