Hi there @sajid_nadeem - nice to see you back in the Explorers Hub.
Unfortunately, we do not yet support Solr version 7.x, which is why you are not seeing some information. I don't know at this point when we might expect to support 7.x, but we will announce it in the release notes when we do.
In the meantime, you can try to capture any missing information using custom instrumentation. Because version 7.x is unsupported (which also means untested) we can't guarantee this will work, but you may very well have success.
Sorry that I didn't have better news for you, but I hope this will get you pointed in the right direction. And please let me know if you have any follow up questions.
