Free Network Analyzer plugin for the open source Nagios

[ds125]

Hi

I've just installed free NagiosPI. Is they a free Network Analyzer plugin?

Or any plugin that can monitor network traffic and bandwidth?

What is it specifically you'd like to monitor? In our commercial product NagiosXI we monitor "network traffic and bandwidth" by leveraging mrtg and check_mrtgtraf.

MRTG gives you the pretty graphs and Nagios can alert on them.

Thanks for you reply.

If possible both. Would like to monitor bandwidth and network traffic across a linux firewall using Nagios core.


Thanks

This is it for traffic (same as previously posted):

For bandwidth, I'm assuming you mean something like "maximimum throughput available between to network nodes" to put it in layman's terms? I've never seen anything like this and am not spotting anything on the exchange - you'll likely have to write something yourself that times a network process that should take an expected amount of time (like wget a 10GB file should take 8 seconds or some such) and then do some processing on the real time. Alternatively there is a check_speedtest_cli if you simply mean bandwidth out to the public network - I have used that in the past with success.

Great!

Thanks for this.


Got something to work with.
