'k, I'm terrible at 'reports', but ... to be totally honest, this has gotta be one of the nicer pieces of software I've played with as far as documentation *especially* for OSS ... I installed it out of ports, initially directly on one of our servers, mistakenly thinking I needed to do one install per server ... ended up moving it into a vServer so that I can easily move it around as I get more powerful servers, instead of having it tied to a specific machine ... On all our other servers, I just had to install the net-snmp port, to give it something to talk to ... The hardest part about setting things up with setting up snmpd, but ended up running snmpconf -i to do this (snmpconf -g basic is apparently slightly easier too) ... once I built the initial snmpd.conf file, I just copied that to the other servers, instead of building one for each ... The Cacti port ends up with a short message that tells you step by step what needs to be done ... it has one "error", in that the crontab entry it tells you to create appears to be wrong ... does Linux support a 'user to run as' arg within their crontab? After that, so far, I've just used the 'default net-snmp' settings that come with Cacti ... haven't had a chance to dive into snmp yet, to figure out what else can be monitored ... I currently have it monitoring CPU, Load, Traffic and Memory Usage You can setup "Graph Trees", so you can group Graphs together .. ie. all the CPU Usage graphs for all (or groups of) servers, so that you can compare them ... So far, at least, definitely a tool I'd recommend ... so far, seems to work well ... ---- Marc G.
