Differences in binaries and docker execution

I'm facing a trouble while i'm executing node-cert-exporter in binary version, following the instructions in the documentation. If I run the docker version I can see in the Grafana dashboard the same that's shown in the documentation's image, but I don't want to run node-cert-exporter in docker version, but binary version. And when I do that I see a bunch of certificates, which are out of the path that I passed with --include-glob parameter.

**What I execute:**
`node-cert-exporter --include-glob /etc/letsencrypt/live/*/*.pem`
👆 that directory contains a dir (my_site) and inside it three .pem files (file1.pem, file2.pem, file3.pem)

**what I want to see:** (something similar with my certificates, which i can see with docker version)

**what I actually see**

**Additional information:**

**Output of `node-cert-exporter --version`:**
