No way I could of done most of it without it. My cacti system collects more than 10 million data points a day, on one dual proc quad core box. More than 95% of the stuff I put into cacti comes from scripts I wrote(I write the scripts to gather many data points simultaneously to reduce the amount of RRD data files stored improving performance by more than 10x.) If someone knows of a better MIB browser I'd certainly be open to checking it out, having looked around quite a bit the past couple years I haven't found anything better myself that runs on Linux. I certainly do agree that SNMP is a black art, not sure why it is so complicated, perhaps it just helps to sell those $100k enterprise monitoring packages because there's little hope for the average admin to figure out how to do it on their own. At my current job(started in March), before I came on they were telling me how the previous admin setup CPU monitoring in cacti, and yet the CPU graphs never seemed to go above 25%. They weren't aware that the CPU usage reported by the snmp daemon used in linux returns useless, completely inaccurate data(this is documented pretty clearly in the daemon documentation but doesn't seem to be common knowledge). I've refined my data collection scripts over the past 5 years or so, they work great now. CPU usage for my cacti systems is sourced from 'sar'. I really hate how sar has gone down hill as far as ability to parse it. RHEL 3 was great, RHEL 4 was ok, and RHEL 5 is almost useless, don't know what I'll do when RHEL 6 comes out. nate
