Sorry, I posted too soon. I made the code change, but never re-compiled the binary. I'm happy to test this if someone can tell me how to re-compile just the RRDGraph.pyc file.

However, all I'm doing is comparing my max with the polled value. The source is a custom snmp script on the client which returns the size of the mail queue. It ranges from zero to thousands depending on the state of the server and the mail load. All I'm trying to do is get an email if it goes over 5000. The graph's scale is 0 to 20k and the RRD file is recording values like 1.1406796517e+04, 5.8250000000e+03, 1.7240000000e+0, 0.0000000000e+00 and NaN. I'm looking into why I don't get a valid value sometimes. My min on the threshold is empty and my max is 5000. It is enabled and is indicated on the perf graph. I'm running 0.22.4 if that helps at all. If I'm not specifying the max in the proper format, please let me know. But from what I've read, this should work. Thanks for the assistance. - Jared -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Eric Newton Sent: Wednesday, October 11, 2006 5:04 PM To: General discussion of using zenoss system Subject: Re: [zenoss-users] Custom thresholds problem Hi Jared, Custom thresholds are very tricky. The RRD graphs can be coerced into producing nice human-readable values like percentages. For example, the Disk Utilization graph that is part of the default /Device/Server/FileSystem performance statistics does this. But ultimately, the number collected for this metric is usedBlocks, and that is what the threshold needs to be against. Of course Zenoss can provide some context, like the total number of blocks available, but the value measured on the device "usedBlocks". I recommend you take a look at the custom threshold on Disk Utilization to see how to construct such a threshold. -Eric Jared Meeker wrote: > Eric, > > Thanks for the previous patch.
