Traffic Volume by Forwarder

This Splunk search query will show you the top 10 “chattiest” forwarders on your network. I’ve used this query to determine why some forwarders were sending more data than others. The results are displayed in kilobits, you could use an eval to change it to the appropriate size for your network.

index="_internal" source="*metrics.lo*" group=tcpin_connections NOT eventType=* | eval sourceHost=if(isnull(hostname), sourceHost,hostname) | search sourceHost=*** | timechart per_second(kb) by sourceHost WHERE max in top5 useother=f
