Hi @Kumar2,
as you can see at https://docs.splunk.com/Documentation/Splunk/8.2.3/Knowledge/WhatisSplunkknowledge Splunk recognize by itself the pairs "field=value".
For the other extraction you can use a Technical Add-On for the standard sources (e.g. Windows, Linux, etc...) or for other sources you have to extract fields by yourself identifying the rule to extract the field and creating a regex.
I could help you if you share some sample of your logs indicating what you want to extract.
regex101.com could help you.
using your sample:
| rex "MyNameis(?<name>\w+)"
that you can test at https://regex101.com/r/PIXYtT/1
Ciao.
Giuseppe
