I have UCD-SNMP (now known as Net-SNMP) running as a NMS (snmptrapd, trap recv). The daemon is configured to run a custom script (which I wrote) every time a trap is received. The script handles all kinds of events (UPS, AuthFail, and Filer).
I run a similar setup at my PPOE.
The daemon (part of Net-SNMP), and the script (written in Perl) are "free", as in "free beer".
...and that's a "good thing".
I also have some nifty polling goin' on with a polling script (again, which I wrote in Perl) which queries the filer, stores the data in RRDs and graphs the data...
I do that too. Unfortunately, with ONTAP 6.3.2 the order in which the variables are placed into the MIB tables changed from the way it worked in 6.1. In 6.1, volumes showed up in the order in which they were created; in 6.3 (and, I'm assuming, onward) the order is based on the order in which the disks in each volume are detected at boot-time. This, of course, made a real mess of my nice long-term data in the RRDs. Has anyone come up with a way to clear that "mess" up? It's a special nuisance when one is trying to manage and gather data from multiple filers....
