Is there an optimal polling frequency for the LogFilter agent?
RESOLUTION:
There is no optimal polling frequency for Log filter.
It’s all depends on your log and how often that log is written. For example, if you have a very idle log which only writes a line every 10 min, then set up 300 sec (5 min) is more than enough.
On other hand, if you have a very busy website like Google and you use log filter to monitor an access log, even 1 sec polling frequency could be bad.
So it’s all depends on your log and how often you wrote to that log.
