Threshold Interface In/Out in Gigs instead of Megs

[Nopales]

Just installed thold and am attempting to set up my first threshold for an interface on network devices. (I've tried both an HP Procurve Switch and PaloAlto firewall) The process of adding a non-templated threshold, selecting the device, graph, and data source. I set the Warn and Alert thresholds, see them in the correct location on the graph, but when it starts grabbing data it is calculating it as Gigs instead of Megs, and I'm assuming this may be some mis-calculation/translation from bits to bytes somewhere. I'm fairly new to the nuts and bolts (I have no idea what a CDEF is). This is a Gigabit interface, so there's no way it's doing 9.91Gigabits of traffic, and of course, that's over the warn and alert thresholds so I'm getting alerted. I see other posts that look similar but none of the ones I've looked at have a solution, or the solution they have is for something other than what is in the subject.

It seems like a common enough issue, is there a goto thread or resource you can point me to?

Thanks so much for the quick response. Here are some additional screenshots of the process. It looks like the graphing function is using the correct units (Megabits) and even showing the HRULEs in the correct location relative to the traffic in the graph, but the "Current" value is incorrect in both the management and view interfaces, as well as being used for generating the statuses, alerts, and warnings. This happens for interfaces on different devices types as well. Is there someplace where the values are being calculated or formatted? I've seen some suggestions to change a row in the mysql database to fix the issue, but I'm not sure if that applies to this situation or if that would have unexpected negative consequences. I'm comfortable with mysql and using the command-line if that would be helpful in generating diagnostic information.

What happens if you change the Data Manipulation to CDEF and the CDEF to Turn Bytes to Bits?

Nice looking graphs by the way. I need to get back to working on Thold as the bugs and feature requests are stacking up. My problem is that there are not enough hours in the day.

[Nopales]

I changed the the Data Manipulation to CDEF and the CDEF to Turn Bytes to Bits and it had no effect. (screenshot below)

When I look at the data source I get numbers:

Max: 2,000,000,000
Last DS: 185,331,699,840,686
Value: 228,425,384

So I'm trying to figure out how we are getting to the numbers in the thold plug-in. Is this configured somewhere? I looked at the tables in the DB plugin_thold* and nothing jumped out for me.

Scratching my head on this as well. I've been meaning to get back into Thold issues, just lacking time. Pull requests are welcome of course.

[Nopales]

Ah, Ok, thanks for scratchin'!

I think that all of my graphs are using 64bit counters and already have the bytes to bits CDEF applied, perhaps thold is applying the cdef again or expecting the number to be in bytes when it's already converted to bits? If this is the case, how do I fix this? Create another CDEF to / 8 and apply that somehow?

Another thought I had was that creating the thold from the create graphs interface might have a different result? Also, each interface datasource looks like it has a "Max" limit, I wonder if one could detect that, and if the thold current value is greater than the max value, provide some path to changing a setting. I'll submit a pull request if I get that far.

Just learn to use the cacti_log() function and put a bunch of cacti_log() statements in the code to see where the display conversion is happening. It's not that difficult. You will figure it out quickly. It'll take a while if you are not used to writing code, or used to basic problem flow.

Hello, I have the same problem. I would like to know if this problem has already been solved?

[TheWitness]

I'm pretty sure that macan fixed this some time ago. Maybe check out the latest tagged release. Tholds is in a bit of flux right now as we are doing some major plumbing work for the 2.0 release. It's going to be a big one, but not as big as the release after that though.
