Netstat

EDIT: Updated to use snmpnetstat

Here's a netstat graph I made for linux.

Steps to install:
1. Copy netstat.sh to %CACTI_HOME%/scripts/ (for me this is /var/www/cacti), and make sure it is executable.
2. Import template into cacti, and start graphing.

You will need to provide the community string when creating the graph, unless someone can tell me how to automatically pass that to a script-type data input.

Unfortunately, I was unable to make it completely SNMP based so I had to wrap snmpnetstat in a shell script; some of my network devices did not have the correct OIDs as described by Howie, but this script input works correctly for Windows, Linux, BSD, and even some network devices!

Enjoy!

This is all released under GPL2 so do what you want with it.

If you're already running net-snmp snmpd on the remote machines, then you can get most of the same info from snmpnetstat:

Code: Select all

snmpnetstat -v 1 -c public -Cs myserver

which in turn suggests that there are probably real OIDs for it too, which is a whole lot more efficient than an exec. And works on non-linux too, even non-Unix.

Just saying.

Edit: This is the MIB that snmpnetstat uses.

Hey thanks I didn't know about snmpnetstat; I'll make the changes tonight.

I have an error when I try to import the template "Error: XML: Hash version does not exist."

I am in 0.8.6j, How I can import your template 0.8.7a into 0.8.6j ?

[pheezy]

I don't think you can, and I only tested it in 0.8.7a, sorry.

Yes, the hash table error is what you get when you try to import a template exported from a newer ver of Cacti than what you're running'


You can only import "up," to a newer version of Cacti, not "down"

Thanks for the netstat template though man... setting it up now ^_^

Just so everyone's aware... make sure you rename "netstat_208.sh" to netstat.sh if you wget it down to your cacti/scripts folder

Here's a screenshot of my modified Data Input Method, that shows how to pass the snmp community string so you don't have to enter it in for every device added... the "special type code" is what does the trick:

Here's my modified templates, for those like me who are truly lazy and just want to import templates

This was exported from Cacti 0.8.7d

Hello,

I am not sure I understood: besides the xml template file, do I need to download something else? Cause I downloaded and imported it, everything looked fine, but the graph displays only nan values.

Then I checked Data sources for the monitored host and discovered that there's only one data source. Is this ok?

Thank you!

[kido]

Forgot to mention this:

Cacti Version 0.8.7d
Cacti OS unix
SNMP Version NET-SNMP version: 5.3.2.2
RRDTool Version RRDTool 1.2.x

Since Netstat pulls from the RFC1213 MIB, you all realize a snmp script/templates have already been created for it -- including TCP stats?

[kido]

many thanks!

Wow... that's really in-depth. No I'd just been searching the forum for netstat and this was the first thread I'd come across. Thanks.

kido: if you're still trying to get this version to work, did you copy the netstat shell script to your cacti/scripts folder?
