Solr performance statistics missing values

### Relevant telegraf.conf

I test the telegraph v. 1.32.2 to the Solr v.8.11.3 with the result that the fields solr_queryhandler and solr_requesthandler all zero values provide.
One and a half year ago i use a Solr v.6 and the values are filled.

What endpoint can i check or provide to find out more informations?
