Network Performance Monitoring

Splunk can monitor network traffic and analyze the performance natively, or in collaboration with network appliances and tools from major technology providers such as Cisco, F5 Networks, or Arista Telemetry.  Splunk monitors almost everything, from network performance, security, system outage, and many others.

TCP Round Trip on Splunk

Splunk shows TCP Round Trip for each protocol

Splunk can capture network traffic from a network TAP or SPAN, these mechanism ensure that Splunk can analyze the network payload for further analysis.

Above is the sample dashboard, when Splunk analyzes network round-trip from various TCP protocols.   It can be seen that MySQL has the best round-trip since it always be called from the LAN, while HTTP has the worst round-trip due to usual bandwidth instability when the opposite end-point is located on the internet.

HTTP Geo Location

Splunk visualizes network round trip for HTTP access from various location on map

Thanks to the built-in map visualization tool in Splunk software, network performance monitoring becomes easy.  We can now easily pin point which network location needs bandwidth improvement to support our business.

Splunk App for NetFlow (free)

Netflow is very useful for capacity planning and determining the causes of congestion, since we can analyze the source and destination of traffic, as well as class of service.

If you have many Cisco Routers, or if you are using routers those are Netflow v5 or v9 complliant, you should consider Splunk to visualize detailed bandwidth usage from your network.  Just download and try.
