Jason,
For a first time poster this is a good question! :) Unfortunately
the answer is that we currently can't do this. Zenoss has simple max/
min thresholds. These can be based on model attributes (the
FileSystem template is a good example of this). Clearly we want to
add more types of thresholds. I think this would be a great
candidate. I have opened a ticket for it.

You could hack a solution for this by writing a zencommand (nagios or
cacti format plugin) that reads the two rrd files and outputs the
division of the two values to create a new data point which you can
create a threshold against.

Hello all,
First Time poster here, obviously. I like zenoss a lot but I have a
question on PerfConf Thresholds.
Ok I am monitoring a CMTS, I have two data sources total modems on
an upstream port and online modems on an upstream port. I want to
compare these two numbers and if online modems drops below 90% of
total modems then set off a warning. I have the Data Sources
working and Can Graph them without problem. But the min threshold
eludes me.
I have tried several different methods and had no luck so far.
Here are my data sources
Online_Modems 1.3.6.1.4.1.9.9.116.1.4.1.1.5
Data Point
Online Gauge
Total_Modems 1.3.6.1.4.1.9.9.116.1.4.1.1.3
Data Point
Total Gauge
I want to set a min threshold that if "Online/Total < 90 " (i.e. if
the number of online modems is less than 90% of the total modems)
then set off a warning.
Thanks,
Jason
