Folks,
I think this is where the logic problem lies within
/usr/local/zenoss/Products/ZenModel/RRDGraph.py
--
def graphOpts(self, context, rrdfile, template):
"""build the graph opts for a single rrdfile"""
gopts = self.graphsetup()
if self.custom:
gopts = self.buildCustomDS(gopts, rrdfile)
res = talesEval("string:"+self.custom, context)
gopts.extend(res.split("\n"))
gopts = self.addSummary(gopts)
else:
gopts = self.buildDS(gopts, rrdfile, template,
self.summary)
gopts = self.thresholds(gopts, context, template)
return gopts
--
IF custom graph THEN
Build graph
Add summary at the end
ELSE
Build graph
Add threshold
END
If I am correct then the above logic does not allow thresholds to
be set
for custom graphs and when building custom graphs it has this anoying
summary at the end.
MY SOLUTION
Comment out the summary and add thresholds.
def graphOpts(self, context, rrdfile, template):
"""build the graph opts for a single rrdfile"""
gopts = self.graphsetup()
if self.custom:
gopts = self.buildCustomDS(gopts, rrdfile)
res = talesEval("string:"+self.custom, context)
gopts.extend(res.split("\n"))
# gopts = self.addSummary(gopts)
gopts = self.thresholds(gopts, context, template)
else:
gopts = self.buildDS(gopts, rrdfile, template,
self.summary)
gopts = self.thresholds(gopts, context, template)
return gopts
//D

Subject: RE: [zenoss-users] Custom thresholds problem
I've read the documentation on thresholds and understand how the Disk
Utilization works. 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

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,
Thanks for the previous patch. It fixed the minimum value problem
with our thresholds. I've found another bug, but I'm not sure where
it is.
I now have a custom rrd datasource and a corresponding graph which
both work perfectly. However, I have been unsuccessful in getting a
threshold to work. I have tried setting the min, max and both at the
same time. There aren't any errors in the web gui, but an event is
never generated. I've turned on verbosity (-v 10) on all of the
daemons, but there aren't any errors in the any of the logs
indicating
any sort of error. I'm not sure why this is causing me so much grief
since I've setup other thresholds which work perfectly. I've
tried to
delete and re-create the threshold, graph, and the rrd source (all
with different names too), but nothing has worked.
Thanks.

Hey Jared,
That error message *is* pretty ugly. I've improved it somewhat:
lappytop test threshold of 3500000 exceeded: current value
3682304.00
lappytop test threshold restored current value: 3158016.00
lappytop test threshold of 3000000 not met: current value
2629632.00
The following change to the 0.22 branch fixes the check against
minimum
thresholds:

Has anyone else had a problem with custom thresholds working? I've
been successful with creating them and having the lines show upon the
graphs, however, I have run into two problems.
1. Thresholds with only a min defined never generate events (no
event
in the app or via email) 2. Thresholds with a min AND a max defined
generate events for both cases, but if the polled value is less than
the min, then the message looks something like this (min=9, max=11):
"[servername] [threshold name] threshold of 2 exceeded:
current value 10.00"
Also, thresholds with only a max defined work as expected.
Thanks in advance.
