Threshold number conversion strangeness

[krash]

I'm running cacti 0.8.6h with the thold plugin. Everything seems to be running fine, but I am having a problem making since of the Threshold current values.

Basicly, I see no way to convert the numbers thold is showing under current into the corasponding numbers showing up on the graph.
I have attached some pics to show what I mean.

These graphs are using the 'Bits per second / Total bandwith' data querry.

Is something wrong with my setup? Is thold using wrong data?

Any help would be appreicated.

This should be the equation you are looking for

((CURRENT * 8 ) / 1024) / 1024

So for instance, in the first graph for the Current Threshold value
((132759.0137 * 8 ) / 1024) / 1024 = 1.0128
which is basically what the graph is showing (I assume blue line = outbound)

So if you want to set the threshold to a 3 Megs limit
((3 * 1024) * 1024) / 8 ) = 393216

I should also probably note that you can create a CDEF for this, and then have cacti use the CDEF. It should work without any issues, but I haven't tested it yet. Threshold CDEFs are only "halfway" working at this point, so no promises.

Thank you for the equations there. Now the numbers make sense.
I havn't tried messing around with the CDEFs, but I will give it a shot.


Thanks again!

I wondering the 'current' value in the threshold plugin displayed. For instance, I added an Disk Used Space threshold, the actual free space on the graph is 3.92G (bytes), while the 'current' value in threshold shows 1262127112200, how can I determine which 'current' value in threshold represents the actural free space value 3.0G (bytes)? In addition, others like traffic in/out bitrate, CPU utilization etc., also have this convertion algorithm question. Thanks a lot.
