Custom Input within Filebeat?

I'm trying to create a beat for Okta.

The only issue is it has to be pull and there's no way to track state.

I wanted to try and hijack off of Filebeat's registar to be able to track state. But I seem to be running into issues. I created a new input, but I can't seem to get filebeat to detect the input. It seems maybe the init function isn't called? I'm thinking about just trying to implement registrar outside of filebeat

In golang, a package needs to be imported, otherwise it won't be built into the binary and its init method won't be called.

You need to run mage update in the filebeat directory so that an import for your new input gets added to include/list.go.

I'm not familiar with Okta, but it feels like maybe you're trying to fit functionality into Filebeat that isn't well suited for it. Have you considered creating your own Beat using libbeat?

Have a look at our Creating a New Beat guide if you haven't already.
