Retrieving the hostname

[NZMM92]

Hello, would it be possible to add a metric to show the hostname of the Fortigate device. Rather than just the IP address of the Fortigate device, and from what I understand that can be retrieved from an existing metric fortigate_version_info.

Hi, Having done some research on my own I found out that it is part of the same API as used for this existing metric fortigate_version_info. However the hostname of the Fortigate device is nested under this json object results, as I am not familiar with Go myself would it still be possible to pull information that is nested under an object from a json response?

Thank you in advance for the help NZMM92

I'm in the same boat since I'm not great with Go. You're correct in that /monitor/system/status returns a hostname: string key-value pair in the json object.

As a workaround I add each target in the prometheus.yml using a hostname instead of IP address:

- job_name: fortigate_exporter
    static_configs:
      - targets:
        - https://my_fortigate_hostname

This does require the hostnames to resolve successfully which can be accomplished multiple ways, either using host settings or by passing hostname:ip_address under extra_hosts in a docker-compose.yml file for example.

The end result is an instance label equal to the hostname of the device, which I can filter in the drop down menu in Grafana.

If you want the hostname attached to all metrics you want to do this in the Prometheus configuration with rewrite rules.

I'm going to keep this issue open as a wish to add hostname to fortigate_version_info
