The instance field in the dashboard

[alexanderek]

Hi

How can the instance field (Grafana) see the System identity, or the hostname of the device instead of the IP address?

Hey! Try replacing the target's ip with its network name, by which it is available on the network
prometheus/prometheus.yml

Example:

......
- job_name: Mikrotik
    static_configs:
      - targets:
        - myrouter.lan # <---- In this place
    metrics_path: /snmp
.....

The host name may not always be resolved. Perhaps there are some aliases?
