Retrieving Flow Information

[vasus]

Folks, Do we have capability of retrieving flow based information from Nagios, Following is the sample topology.

Example

Host1---Router1-------Router2-----Router3------Host2
------------------------ \------- /
------------------------Router 4

If particular traffic flow is going from Host1->Host 2.
Traffic can potentially take 2 paths
Path 1: Host1->Router1->Router2->Router3->Host2.
Path 2: Host1->Router1->Router2->Router4->Router3->Host2

Question 1. Assume you enabled Netflow on all 4 routers above, can NAGIOS figure out the Paths (like Path1 and Path2) taken by one particular stream of IP (TCP/UDP) flow. (There is only 1 Netflow collector collecting NF packets from all 4 Routers.

Question 2. If Router1 and Router2 and managed by Netflow Collector1 (1st instance of Nagios) and Router 3 and Router 4 are managed by Netflow Collector (2nd Instance of Nagios. Do we have mechanism to consolidate these 2 Netflow Collectors and gather the flow information (as asked in Question 1)

Nagios doesn't have a Netflow analyzer builtin, however we are working on building a separate product that can be used for Netflow analysis
