Incorrect graph data?

[jordanr]

Hi All,

I'm new to cacti, have just set it up with three hosts and with great thanks to these forums - am now graphing what I need to.

However some of the data is definitely wrong, and because of that I can't trust any of it. Can anyone tell me how I can check to ensure values are correct, and if not, fix it so they are? I will attach a picture of all graphs for one host (all three hosts have the same graphs) inline.

I am using:

Debian Etch/Lenny
Cacti 0.8.7b
Net-snmp 5.2.3-7

Any help is greatly appreciated.

Cheers

I think you use UNIX* Graph Templates for all of that three hosts.
On one (localhost) works fine, couse UNIX* Templates you can only use to the local machine.
To monitor remote hosts use other like ucd-net or Host MIB Graph Templates.

Alex.

Cheers for the tip Alex, however I've added all these graphs using ucd/net (I believe).
