Description of the problem including expected versus actual behavior. Please include screenshots (if relevant):
I have a custom cli node app that I wan't to add APM metrics too.

I can see see in the APM page that something has half worked as the APM page has
headers ready for my transctions but not transactional data. See Provide logs
and/or server output
for more detail.

Steps to reproduce:

I have const apm = require('elastic-apm-node'); at the top of the entry point.

I've configured and invoked apm.start(config) with the correct values.

I create a transaction const trans = apm.startTransaction('cli', 'job');

On success/failure I set

    trans.result = `success`;
or
    apm.captureError(err);
    trans.result = `error`;
finally
    trans.end();
    apm.flush();

Provide logs and/or server output (if relevant):

I can see my Service named correctly, but when I drill down there are no Transactions.

When I show the Metrics tab the Host filter correcly lists my hostname.

The environment drop down correcly lists my environment development

When I set ELASTIC_APM_LOG_LEVEL=trace and run my node program
I can see that it is attempting to transmit it to my APM server.

But I get no information on whether it was successful sent to the
APM server or not in the console output.

I've also tried adding apm.flush() after trans.end().

setting transaction result { trans: '935441245482b465',
  parent: undefined,
  trace: 'e069a3022ae80770da995b7dfe60af03',
  result: 'success' }
sending transaction { trans: '935441245482b465',
  trace: 'e069a3022ae80770da995b7dfe60af03' }
ended transaction { trans: '935441245482b465',
  parent: undefined,
  trace: 'e069a3022ae80770da995b7dfe60af03',
  type: 'job',
  result: 'success',
  name: 'gb-job' }
no active transaction found - cannot build new span
intercepted call to https.request { id: null }

Now that some time has passed, and I've run this a few more times, I can finally see some dots on the screen.

I suspect that the problem is the graphs do not show single values well when they are at the far right edge of the graph, as will happen when you check on the most recent transaction.

With only a single transaction the transactions per minute is doesn't show any lines at all. Now that there is more than one transaction a green line is displayed, even if it still shows 0 tpm.

I can now see something under Transactions at the bottom of the page.
I do not recall if that was populated or not when I first posted.
Clicking on it, drills down into the most recent trace sample and I can see that it is doing something.
