Monitoring adaptive load reduction

[henk_stobbe]

Hello,

From the documentation I understad that you are warned if ALR kicks in:

    You are informed about the reduction of processed data by

• An alert message in the Dynatrace web UI: Server [amount] activated adaptive load reduction

• A message in the distributed trace list: [amount] more like this   

 Does this simply mean that whan a service exceeds 1000 request/s this happens. Or in other words can you monitor this number with a threshold of 900 if you want to prevent this from happening?

"Adaptive load reduction" and "Adaptive traffic management" are sometimes treated equally, despite being a little bit different. You quoted the following page, which also mixes these two concepts:

If we're talking about a Managed environment, ALR is more adequate. There have been discussions here in the past, and I would suggest the following two threads:

• https://community.dynatrace.com/t5/Dynatrace-Managed-Q-A/ALR-and-controlling-server-resources/m-p/11...
• https://community.dynatrace.com/t5/Dynatrace-tips/Understanding-and-fighting-ALR/m-p/172092

If we're talking SaaS, then this thread might also be interesting:

https://community.dynatrace.com/t5/Open-Q-A/The-Problems-with-Adaptive-Traffic-Management-Version-2/...

Additionally, if talking SaaS, I believe Grail will impact the way traces are stored. but this has not been anounced, to my knowledge.
