  1. Comment from Tom Lobato

    It`s worth to comment that the error:

    mobile:~# php /usr/share/cacti/site/poller.php

    Fatal error: Call to undefined function: mysql_pconnect() in
    /usr/share/php/adodb/drivers/ on line 367

    is not solved in debian etch (at least) with the instruction above. I had to tell
    php CLI to load to get it working.
    In my case, I created the file /etc/php5/cli/conf.d/mysql.ini and added the line:

    Remember, “your mileage may vary”, maybe you have to add this line in another file,
    study your distribution and version.

    After this, I get:

    mobile:~# php /usr/share/cacti/site/poller.php
    01/07/2008 05:18:55 PM – SYSTEM STATS: Time:1.0205 Method:cmd.php Processes:1
    Threads:N/A Hosts:2 HostsPerProcess:2 DataSources:5 RRDsProcessed:5

    OK u:0.00 s:0.00 r:0.00
    OK u:0.00 s:0.00 r:0.00

    and the graphs appears nicely, so my customer can smile happy =)

    i’m fix this error via “apt-get install php5-cli”

    It’s work.

  3. The hardware requirements are very minimal.. a SNMP query is an extremely easy task to do. There is very little SQL work being done; the only CPU or memory intensive operation is when a client is viewing graphs.

    My Cacti box is a (Linux) machine with dual 600mhz CPUs, and 256MB ram.
