More Utilization Graphs

Playing around more with RRDtool and SNMP stuff I ran across Cacti as a front end for both. Tweaking, tweaking and more tweaking. I also have noticed a difference in the queries … Some report higher volumes than others, and I haven’t looked into the “meat” of this yet. Getting the graphs to work and accumulate data has been the main focus of direction thus far. I was able to make immediate modifications that were important to me. I will dive into the accuracy later. But, whether completely accurate or not, it does show a trend based on whatever data it is collecting. In the case of the routers and switches, I have MRTG graphs to compare it too. I am sure as I play more with these technologies, I will create custom graphs to show what I need. Only other thing I might mention is that Windows again is reluctant to play along in this endeavor. I had SNMP already installed and running on one of the oldest servers I brought up (imagine that), but on another I had to install it. After installing it (and it touching things I didn’t want it to), it surprisingly didn’t ask for a reboot, but I got an alert about it wanting to act as a server. So I said yes and immediately was graced with a BSOD. After a very long time of letting it dump, I gave up and banged the reset key. While it appears to be a functioning server at this point, SNMP data polled from this machine is incomplete. There is hardly any disk information at all, and that’s something I want to monitor. Oh well … The Windows portion of the network is going to be rebuilt at some point, so this is just another reason why.
