Collector test returns Killed about collector HOT 3 CLOSED

After running
/usr/bin/pganalyze-collector-helper status

I've got this:

Failed to find Postgres Postmaster Pid: exit status 2
{
  "PostmasterPid": 0,
  "DataDirectory": "",
  "XlogDirectory": "",
  "XlogUsedBytes": 0,
  "SystemIdentifier": ""
}

I don't know if helps more, but I saw that command in a older issue of yours: #13

@nathaclmpaulino This should be unrelated the pganalyze-collector-helper - that helper is only used for self-managed systems (i.e. not RDS)

Whats likely the problem here is an out of memory. Could it be that you are using a very small EC2 instance? (e.g. t3.micro as we currently describe in the docs)

If you have a lot of queries on the database (or many with long query text), you might need to use a larger EC2 instance, such as a t3.small instead.

You should be able to confirm this by running dmesg -T on the server, you should see the Linux out of memory logic kill the collector process at the time of running the test.

Yep! The process was killed by OOM. I will run another machine on monday.

Thank you! @lfittl
