[analog-help] using cache files, REQUEST report too big

[Kevin Creason]

I update the cache files at the end of month when we roll a new log.
Our logs are ~1gb a month, so cache significantly helps.

I have a wrapper script that I use to regenerate cache files with the 
new parameters when needed, and update on the first of a month. I was 
amused with 7day figure when it was working on older log files.

Before the cache files, they were just boring independent monthly 
reports, no history between months. The cache is great, just getting 
there has been a challenge.

Thanks for all your help.
