Is this a new environment? Can you some details about your environment. Especially when you talking about node04, etc.
And what exactly is internet traffic? Is it a dedicated network interface?
Hi @cwiechmann, can you gently provide your Axway business mail so that we can communicate more details on that channel?
Thanks Gianmario
Hi @giancolli, Please check the behavior of Logstash and if it caches API-Details properly. Please check this video if you haven't done yet to understand what to look for: https://youtu.be/rLT84dkgGAE?t=290
Let us know, the metrics you see in Stack-Monitoring.
Hi @cwiechmann, Logstash seems to be fine, especially after starting the second node at around 11:00
FYI, we also have opened a corresponding Axway Case (01384086) and a meeting is scheduled for Monday, 14:00 CEST.
Yes, that looks perfect! And what about the APM Details for the API-Builder API requests?
Sorry, I missed that part
If I get this right, this indicated that we're not caching enough paths again?
I just checked the APM dependencies and found that the above mentioned node04 is having lots of requests:
This should also explain the higher load (its basically the admin node manager of the secondary cluster) - interestingly node01 is not listed as a dependency...
Edit: the second listed one is a different hub altogether

Question
Hi @cwiechmann, this issue is a follow-up of issue #180 .
After your analysis we applied suggested cache configurations on the envSettings, acting on the _CACHE_APIPATHS parameter.
Nevertheless, we still face a very high amount of Cassandra Mismatch blocking when the API Builder is running.
Other interesting point is the following: Considering this configuration (EMEA)
ADMIN_NODE_MANAGER=EMEA|https://node01.***.net:8090,EMEA|https://node04.***.net:8090
We noticed that when the API Builder is on, ONLY node04 faces a high increase in:
CPU Usage
Internet traffic received (normal amount is about 5 GB/hour, with the builder goes over 50GB hour)
Note: API Builder was on from around 10 to around 18
Can you gently help us to:
Thanks Gianmario
