[WhatsUp Forum] Monitoring queues in a Barracuda Spam firewall

[Grant Griffith]

Well, here is some info from the Barracuda forums.  Does anyone have any idea on how we can convert the string to int inside WhatsUp?   Hello, I am trying to get this working with WhatsUp Pro 2006 and am not able to find these OID's when using their graphing utility. Has anyone successfully monitored these using WhatsUp? Thanks, Grant Griffith WhatsUp seems to have problems graphing and monitoring numeric strings. The BSF uses the NetSNMP external command functionality to present this data and the OID enterprises.ucdavis.extTable.extEntry.extOutput.x is typed as a string. I haven't found any way to force WhatsUp to do a string -> int conversion, though it does seem to treat a string with a value of 0 the same as the int "0". So if your queue size is generally zero you can set a service up to monitor enterprises.ucdavis.extTable.extEntry.extOutput.x and tell it that 0 = up and it will monitor it as up when the queue size empty. However, since you cannot seem to force it to do the string -> int conversion you cannot set up a service that monitors enterprises.ucdavis.extTable.extEntry.extOutput.x for values between 0 and 500 (or whatever you think is a queue size that should alert you). The best course of action for Barracuda Networks, IMHO, is to get a SMI enterprise code and return all of their Barracuda specific items there. That way they can set up the MIB however they like and these type of problems won't crop up. Though, for the most part this isn't really a problem for people because most monitoring platforms can figure out how to deal with ints in a string field. I was fairly suprised when I saw that WhatsUp had this issue, as I'd been graphing my queue sizes with Cacti for some time and didn't expect to run into any problems define a service in WhatsUp.   Thanks, Grant Griffith Web Application Developer Enhanced Telecommunications Corp.
