Network monitoring using Nagios

[lafargeuser]

Hi Team,

out of these how many parameters can be monitored by Nagios XI

WAN optimization services (Riverbed) and WAN aggregation (Talari)
Real-time view
Pre-emptive and predictive analysis
Top-talker / top-listener per hosts and applications
Trend analysis and capacity planning
Problem detection
Network services SLAs

Those are pretty broad requests. Do you have specific examples of what you are trying to monitor? Some of those things on the list we do have (such as capacity planning and problem detection) but it's hard to give details with such a far-reaching list.

[lafargeuser]

okay.
Can I monitor below parameters with Nagios Network Analyzer tool.

WAN optimization services (Riverbed) and WAN aggregation (Talari)

As long as they provide some form of flow output, yes this should not be an issue.

Pre-emptive and predictive analysis

What exactly are you looking to pre-empt and predict? You could certainly integrate with nagios xi and use the capacity planning functionality to some extent. I do not believe there is anything currently implemented for this otherwise.

Top-talker / top-listener per hosts and applications

Hosts, yes. Applications, not unless they use a specific port. Flow data does not contain too much if anything, in the form of application layer information. It would contain src and dst port, hosts, and size of data, but it's not going to contain the full payload from the packet, so further analysis on what application it might be isn't really possible.

Not quite sure what you mean by this, but NNA deals with Netflow data and I don't believe this information would be included.


Pre-emptive and predictive analysis

There is no predictive capability currently, however if enough interest exists it could be added in the future.


Top-talker / top-listener per hosts and applications

There is a top-talker report that will work for hosts and ports, but Netflow doesn't indicate what specific application is in use.

If I use Nagios Log server will my requirement fullfill.
Is it to be installed on individual server.
How can I integrate with Nagios XI. If some of given requirement are possible with this then I will be good to go.

Also let me know the capabalites of Nagios Log Server

I don't know what your requirement is so I can't answer this. Please provide specifics.


Is it to be installed on individual server.

Logserver is designed to be run on its own server, yes. We typically recommend that all of our products be run in their own environment.

This is another broad question, but our products page will give a broad overview: http://www.nagios.com/products/nagios-log-server
