Yep. I might consider running it under the installed pcp-testuite
package (as the pcpqa user), instead of under the source tree.
Let me know how it fares. May I suggest running a quicker, './check -g
sanity -x flakey' run first, to make sure things are setup properly
before running a full testrun?

I add the pcpqa user into the system, and run test under the pcp-testsuite package.Â

When I run "./check -g sanity -x flakey" it has permission problem.Â

So, I issued the command with sudo, which executed without any errors.

In terms of the testsuite, (sudo ./check 000-)

some tests report problem like output mismatch, or some packages are not found(e,g, no docker binary found),

but most of these tests pass.Â

Do I need to investigate the test with problems and fix them? Â

Sure, just be aware that we do have a memcache pmda, as well as several
database pmdas already (check src/pmdas/ for a full list). That being
said, there are always more databases to monitor. Feel free to choose
one you're interested in and detail it in your proposal.

I looked at the listed provided, I think I can write agents to monitor redis or cassandra database,Â

if that's possible.Â
