Scale Problems

Hello, I got a template from a dev forum that graphs DNS requests on my BigIP devices. The person who made the template is using the exact same Cacti version.

The graphs come up but the vertical scale is wrong. I'm not even sure where it's grabbing the units from. I've spent many hours in the graph template of this DNS graph changing around in just about everything. The problem still remains.

The top pic is a screen shot from his graph using the template he posted. The bottom two are mine, using the same exact template.

Why am I getting units (m) on one and none on the other. Why are the vertical scales so different in numbers? How can I set the vertical scale so it's like his? I've already chatted with the person who made the templates, he doesn't know what I should do. He recommended that I seek the Cacti forums.

It's an auto scaling issue. If you want a fixed scale, you have to modify the Graph Template to do so. Editing Graph Templates is pretty harmless, if you know what you are doing.

As I've mentioned in my initial post, I've been in the graph template for hours trying to get the vertical scale to work correctly. Sadly, haven't been able to fix it yet.

What baffles me is two things:
1) I'm using the same exact template that the author used, but yet get a different scale than him. Doesn't the graph template import his settings also when I import his template?

2) Why does one of my graphs have units (m) and my other one does not? Why is one of my graphs using totally different scaling increments than my other graph? Both my graphs are using the same exact graph template.

m stands for "milli", aka very little. If you disable autoscale and set the max value to, say 100, then you will not see milli, but your graphs might appear blank.

Sorry, but I'm still confused on why my graph scale units are all weird. I understand m if for milli, but that doesn't make any sense on the graph. There is no such thing as a milli query.

It seems to be graphing is correct, but the scale is off. How do I get the same scale as the top graph?

Likely you apply a CDEF or find out what's wrong with your script.

Found this post while investigating the same problem. Yes turning autoscale off and setting a logical upper-limit gets rid of the "milli' units, but how do you get rid of them for your GPRINT values?

Thanks.

Nevermind, I forgot to use the "Load Average" GPRINT preset. This gets rid of the scaling .
