Possible change to multiplier

[andydouth]

Is it possible to make a suggestion, as when adding a mulitplier I would actually like to divide the values collected. This would be a useful feature for me so that I could calculate the Bandwidth utilization percentage as the only way I can think for producing the values using SNMP v2 values.

Or have I missed something and is there an area somewhere where I can perform calculations on the data collected?

Do you want to delete by 8? Use multiplier 0.125, by 10 - 0.1, etc.

on this subject. could we get a formula instead of multplier?

so we could enter say ... -100 or -1 or *100 or /5 or +8

The only need i can think of now is that there isn't a total CPU usage for unix. Only a idle,wait,user,system,etc. 100-idle would be the answer for total, but that isn't possible.

I haven't thought of how this would be done internally, but probably not as easy as just "multiplier"

I have tried using a decimal fraction i.e. 0.125 but this just returns 0 constantly, when I can see the item without the multiplier is something like 450 K.

That is my problem if it worked it would be fine, although not ideal. I could then work out the fraction I needed to mulitply by in order to return a percentage of the total bandwidth used.

Cheers.

I agree i bbrendon I think this would be quite useful as I am only interested in using the SNMP values therefore I could calculate a lot of useful values with a formulae capability

Cheers

This is the feature I need zabbix to do, With cacti I am able to perform just about any conceivable calculation on the data in order for example to convert a voltage or mA output from a sensor into a real value such as temperature, pressure, humidity etc. It is often the case that to calibrate the output value to correct units one needs to add, or subtract a value and then multiply by some factor.
Some additional calculating capacity would definitely be of real benefit to zabbix users.
