after a success testing and poc of elastic APM in many components and technologies, we are now testing it integrated with all components and thinking what should be decent settings for agents to have good performance of the apm components but enough data for troubleshooting as well.
Firsts tests seems quite heavy because we generated too much data (several GBs for a couple of hours) when we expected to have 10 at most for a day.
So I will start tuning the agent settings as the defaults seem too much but I'd like to ask to community first what is the configuration you have that is valid to you?
transaction_sample_rate: default is 1.0. I reduced initially to 0.5 because I thought 100% was too much, still should be reduced? 10% even 5% should be significant enough, what you think?
span_frames_min_duration: default is 5ms I haven't touched it but seems is commented by default so not applying, I'll play around with it
So, any recommendation on good values for performance but keeping a good instrumentation as well?
