Re: [Devmon] Host with multiple snmp strings

[Ken C. <kco...@ry...>]

I've had no luck with the "snmp:cid(my2ndstring)" with this one...

I do have other deivices that are monitored with a different strings with the "tag" and it works just fine.

I ended up just writing an external script to fetch that data and update Xymon.
