I have managed the data of IP Phones in Fujisawa-site , Japan by CMDB
So I want to track the data of it by Splunk.
Tell me how to use Splunk to track the data by CMDB.
If you're looking for an efficient and functional ServiceNow to Splunk integration (also CMDB) take a look at: https://www.thedutchdatadifference.nl/splunk-servicenow/
I created that solution and continuously adding new features. One of the use cases I have done is comparing data available in Splunk with what is in CMDB.
You can add the CMDB data as a lookup in Splunk, either as CSV, or via a DB lookup.
Besides that, your question is very broad and generic, so it's pretty hard to get any idea of what you have, what you want to do, and how it could be done.
Also,you might want to use the word "please" in future requests.
Thank you for your comment,
I would like to confirm the data statistics of CMDB with Dashboard of Splunk
Because I can see visualizing registration data by dashboard
