Hi Gajendra,
mysqld_exporter collects information about InnoDB and TOKUDB storage engines by default.
So such error just means that TOKUDB  storage engine hasn’t installed.

ok, so is there any parameter which can stop this error in pmm

because i dont want to install TOKUDB

I don’t think so, this is a known issue on our side: PMM-4665.  Please feel free to watch it or upvote it to get more attention to it.
