Filter Entries from going into Apache Logs

Question

I have a setup where heartbeat is grabbing a website every couple seconds. I would like to filter out these entries from the Access Logs.

Are there any apache directive or modules that will make so I can keep these entries from ever being written to the log in the first place?

Answer 1

Yup, use SetEnvIf along with CustomLog

e.g.

## Ignore anything from 127.0.0.1
SetEnvIf Remote_Addr "127\.0\.0\.1" nolog
CustomLog logs/access_log common env=!nolog

Answer 2

Looks like I might want 'Piped Logs'.

Although if anyone has a better solution, or any caveats to watch out for when using that, I would appreciate that. The major caveat mentioned on ths site I see is:

"Piped log processes are spawned by the parent Apache httpd process, and inherit the userid of that process. This means that piped log programs usually run as root. It is therefore very important to keep the programs simple and secure."
