Issue Creating a Custom Metricset

Elastic Stack Beats
1

I am working to create a custom metricset for Metricbeat but am having difficulty with the documentation. I am following the guide here, have installed go, mage, ran go get for the beats repo, am writing the module within my $GOPATH, etc etc.

I have no issues running make create-metricset and can verify that it ends up creating the module within module/{module} as well as a metricset in module/{module}/{metricset}/. The issue is, when it says to run make collect and make (here), I get the error:

make: *** No rule to make target `collect'. Stop.

When looking at the Makefile, it seems like there is no command collect. When I try to run make, I get

Use mage rather than make. Here are the available mage targets:

So instead of using make, I tried doing the following:

mage collectAll
mage build

Now, this works and compiles me a binary that runs metricbeat successfully (./metricbeat -e). However, the module/metricset I created are not recognized:

2020-10-26T14:51:00.604-0400	INFO	instance/beat.go:423	metricbeat stopped.
2020-10-26T14:51:00.604-0400	ERROR	instance/beat.go:940	Exiting: 1 error: metricset 'metricsd/server' not found
Exiting: 1 error: metricset 'metricsd/server' not found

I was wondering, is this an issue with outdated docs? Is there a new process, or am I missing something here?

It looks like the docs might be a little out of date. Try mage update in the metricbeat directory, and see how that works.

Works perfectly, thanks!

Just out of curiosity, if I "fork" previous metricsets on Metricbeat to create my own metricset, am I violating the Elastic License? If so, what's the best way to "learn" how to create one?
