Help adding Network Interfaces

atomsk47 · Post by **atomsk47** » Mon Jul 06, 2009 7:07 pm

Hello I am very new to Cacti and I have added several linux servers. The only thing I have left is adding their network interfaces to monitor traffic. I really need this but I just haven't been able to figure out how to do it I have been searching for the past 2 hours with no luck. I have a feeling it is something really simple but I just haven't figured it out yet.

Thanks,
Grant

Well, if it is properly configured, just go to Console/Devices/{Device Name}, then click 'Create Graphs', then select the interface.

If not:

Which template did you use to create the device?

When viewing the device, what is under 'Associated Data Queries'?

If SNMP - Interface Statistics under Associated Data Queries, what does it say in the status column?

The Template I used was Local Linux Host
The only thing under Associated Data Queries is "Unix - Get Mounted Partitions"
Here is the Querey Debug Info

Code: Select all

Okay so I try adding SNMP - Interface Statistics while also having "Unix - Get Mounted Partitions" "SNMP - Interface Statistics" returns 0 Items and 0 Rows. If it is just by itself it works and reports 35 Items and 4 Rows.

I could have been a delay in retrieving the information. Try adding the Unix template again.

The "Local Linux Host" template is for exactly that - the local linux host (i.e. the one running Cacti). It uses scripts, so you can't use it for remote servers.

So does that mean the data being recorded for all the servers will just be data taken from the localhost and not the remote server?

Yes. You can prove this for yourself by looking at (for example) the load average graph on all the servers.

To measure the remote servers without writing your own scripts, you need to install net-snmp's snmpd on each server, and then use the 'ucd/net snmp host' template instead.

Nice catch Howie, skipped right over that...

I'll add 'create and add Linux Server template to base install' to the list of topics we are discussing at OSCON this summer.
