FILEBEATS CPU OVERHEAD CODE

In addition to that we're always selecting our default configurations to be as low-overhead and as production-ready as possible while still providing valuable information. Also, we're always trying to make the Agents even more robust also in terms of overhead.

FILEBEATS CPU OVERHEAD CODE

around Auto-Sensor overhead limitations) and are implemented in the Agent code itself. Some of those turned out to be effective (e.g. However, over the years we investigated multiple approaches to try to estimate and limit the Agent overhead. The only really reliable way to measure the overhead is and always will be to make reasonable load tests with an external tool including reproducible load and warmup/cooldown phases executed multiple times with and without the Agents. Measuring the overhead is also non-trivial, as the Agent itself is part of the whole system and can as such not easily measure itself.

level of detail of captured information.

number of placed sensors & instrumented methods.

type of Agent (OS Agent, Java Agent, Network Agent, Log Agent.

from the Agent & configuration perspective:.

inter-process mutexes and other dependencies.

amount of remote communication and IO interaction.

number of concurrently executed threads.

requests per second (or some other load indicator).Such factors include, but are not limited to e.g.: The overhead of the Agent (regarding response time, CPU, memory & network traffic) depends on so many factors and their correlations that it's just impossible to estimate it upfront. I'll paste the responses with information from dev directly form a support case where this was asked:
