Telegraf is configured with basic host telemetry by default. You can add more features, if you like:
- `telegraf_docker`: Set to `true`, if docker telemetry should be collected (uses file from `telegraf_docker_file`)
- `telegraf_snmp`: Set to `true`, if SNMP telemetry should be collected (uses file from `telegraf_snmp_file`)
- `telegraf_unifi_usg_ips`: Specify a list of USG IPs, if SNMP telemetry should be collected (uses file from `telegraf_unifi_file`)
- `telegraf_unifi_ap_ips`: Specify a list of AP IPs, if SNMP telemetry should be collected (uses file from `telegraf_unifi_file`)
- `telegraf_docker_file`: filename of the docker telegraf config part in `{{role_path}}/templates` (default `telegraf-docker.conf`).
- `telegraf_snmp_file`: filename of the SNMP telegraf config part in `{{role_path}}/templates` (default `telegraf-SNMP.conf`).
- `telegraf_unifi_file`: filename of the SNMP telegraf config part in `{{role_path}}/templates` (default `telegraf-UniFi.conf`).
Optional settings:
- `telegraf_interval`: Data sampling interval (default `300s`)
