Network Metrics of HTTPS Software Service which without SSL keys imported into NAM Probe.

I do understand if no SSL key is loaded into the NAM Probe, the HTTPS Software Service configured would not have URL breakdown (and thus, no information on response time, application performance, availability etc.)


But what about network metrics (e.g number of packets transferred, loss rate, rtt, bandwidth usage, network time etc.)? are those metrics able to be trusted even without SSL key loaded? or they are just like other metrics where they can't be trusted if no SSL key is loaded?


Best Regards,

Hi,

All network metrics will be reported as usual and will carry their respective value even when SLS decryption is not configured (or not possible).

Please note that the SSL layer operations will also be measured without decryption and they are valuable to monitor performance and availability of the SSL layer (and thus, indirectly, the app itself). See https://www.dynatrace.com/support/doc/nam/shortlink/id-monitoring-ssl-encoded-traffic-without-decryption and https://community.dynatrace.com/community/display/PUBDCRUM/SSL+Monitoring+and+Decryption+FAQ#SSLMonitoringandDecryptionFAQ-WhatdoestheDCRUMreportinpresenceofDiffie-Hellmanencryption?
