Graph Proftpd metrics.

[btimby]

I found the following post regarding graphing the number of proftpd users.

However, I have a couple of problems with this solution.

1. It only graphs the number of users.
2. It uses a two-phase process whereby a cron job writes stats to a text file and SNMPD reads from that file.
3. It had a bug that if no users were connected, the output was "no" rather than 0.

Therefore I reworked the script and Cacti templates to gather data directly via SSH and it now returns 4 metrics:

- user count: number of authenticated users connected (same as other script).
- uniq user count: number of authenticated users connected with different names.
- ftp uploads: number of uploads (STOR/STOU/APPE).
- ftp downloads: number of downloads (RETR).

I placed the script, templates and a README into the attached tarball. I hope somebody finds this useful!

*** UPDATE 10/30/2009 ***
I have uploaded a new tarball, it contains a fix for proftpd_users.sh, there was a "|" char missing in the UPLOADS calculation. "STO[RU]APPE" -> "STO[RU]|APPE"... Or just download the new tarball.
