I'm looking for tools or ideas in analyzing client traffic in a cluster. Let's take the example of a cluster of 6 NSD servers, 6 100 TB file systems, 100 clients. Assume all of the file systems have NSDs on all 6 of the NSD server nodes and are"well balanced".
- How can I identify which clients are driving the most load to the cluster in a holistic view?
It's fairly straightforward to take a look at an individual NSD server, see which clients are driving traffic (using thing like mmpon/dstat/iftop). But I'm looking at something that will tie the whole cluster together.
