How to create network monitoring report for netflow and sflow data ?

Explorer

Hi,

I have ingested netflow and sflow wire data into splunk from our Juniper switches. But there is no visualization app with inbuilt/default dashboards. Basically i am looking for network monitoring report via Splunk similar to Manage Engine/Solarwinds/Ipswitch dashboards.

In the report i wanted to calculate metrics such as bitrate (bps) and traffic volume (bytes transferred in MB/GB).
The search query should calculate these metrics for both netflow and sflow data which has the relevant data in different field names.

Sample ingested sflow V5 and netflow V9 data fields are attached.

Hi David,

For sflow: I could not find any Splunk documentation reference. Any thoughts on the below queries related to sflow ?

What are the fields that has to be used for calculating bitrate in sflow?
What is the formula for calculating bitrate from sflow V5 data ?

For Netflow:
What is the formula for calculating bitrate from Netflow V9 data ?
