Andy, wonderful to hear from you. And thanks for your method of getting snmp traps into Hobbit. It is a bit of a feather in my cap that I can do so. My boss is anxious to get rid of our highly priced NetCool monitoring package, but we needed to be able to monitor traps, at least from our F5 devices.
I haven't modified trap.pl in a very *long* time. Hmm... (I'm still using it.)
Going back over the code, I'm running hobbitdboard so I can get the validtime field for the test: "$BB $BBDISP \"hobbitdboard test=trap fields=hostname,validtime,color\" "
In case there's a host that doesn't send a trap that often, I wanted to change the color to green instead of having it go purple and generate an alert. So to get the time left for a test, I needed the hobbitdboard results. A side-effect is that the column won't appear until the device sends it's first trap.
Yes, I looked again at the code and realized that I was mistaken, and have already apologized to Henrik for having the temerity to suggest that there might be a bug in his code.
For the problem device, is the log from SEC showing a hostname or IP address for the device sending the trap?
Yes, but that was sometime ago. Maybe before I made some other corrections to get things working. I'm tempted to just down a server to cause a trap.
There may be a problem if it's sending a status message to Hobbit with an IP address instead of a hostname. I don't think trap.pl does a good job (or at all) of trying to resolve an IP address to a hostname that's in bb-hosts.
Yes, I've seen that. In order to get things to work, I've had to make /etc/host file entries and make sure that the sending devices are configured to send their traps via certain interfaces so that the IP address will correspond to the host file address.
Hope that helps, Andy

The trap.pl uses hobbitboard to find all the hosts that have the "trap" test defined.
Bad idea - there's a chicken-and-egg problem here.
Columns do not appear in the hobbitdboard output until they exist, i.e. a status has been reported to Hobbit. So if *something* must report a "trap" status to Hobbit before the trap.pl script sees that it should do the "trap" thing ... well, I guess you can tell where I'm going.
Scripts that implement custom tests should use the "bbhostgrep" utility to scan the bb-hosts file for the hosts that have a specific tag defined.
There is actually another way it can be done, but it's not yet documented: You can send a "hostinfo" command to hobbitd, and it will return a pre-parsed version of the bb-hosts file - one line per hosts, with the fields delimited by '|' characters, eg: mail.hswn.dk|172.16.10.2|NET:intern|COMMENT:Internal mail server|smtp|pop3|imap
