Hello, Thanks for the earlier reply. I am a little confused with documentation and the response from Josh. This may be my limited knowledge with Phoenix.
Can I connect to the server with thick client instead of thin for my server which is running thing client since thick client seems to be running on PQS? Additionally I followed the directions on https://phoenix.apache.org/server.html and the above linked conversation, but I am unable to generate any kind of metrics for any queries. Please note that in this scenario I am running my queries via the think client installed on PQS For a particular query, I am trying to see how many rows are being scanned and across how many region servers. If there is an easier way, please let me know On Thu, Oct 18, 2018 at 7:00 PM Monil Gandhi <mgand...@gmail.com> wrote: > Okay. Will take a look.
