Configure mktxp for Mikrotik RouterOS devices

Only first time:

Add to /home/pi/IOTstack/services/prometheus/config.yml

  - job_name: 'mktxp'
    static_configs:
      - targets: ['mktxp_machine_IP:49090']

ssh to router

Add monitoring group and user:

/user group add name=prometheus policy=api,read
/user add name=prometheus group=prometheus password=***

Add router config to the mktxp docker (192.168.1.162):

/home/pi/IOTstack/services/mktxp/mktxp.conf:

[CRS326-01]                               # Change to your Router

    capsman_clients = True

    firewall = True

    wireless_clients = True

    use_ssl = False

    pool = True

    wireless = False

    monitor = True

    capsman = False

    netwatch = True

    ssl_certificate_verify = False

    enabled = True

    use_comments_over_names = True

    no_ssl_certificate = False

    dhcp_lease = True

    dhcp = True

    route = True

    interface = True

    poe = False                         # Enable for PoE stats

    hostname = 192.168.1.2              # Change to your IP

    username = prometheus               # Change to your Mikrotik user

    password = ***                 # Change to your Mikrotik password

    port = 8728                         # Default Port for Mikrotik API

Issues: files were created as directories:

./services/telegraf/telegraf.conf

set hostname value under [agent] in telegraf.conf

Manually Added snmp to docker-compose.yml:

  snmp:
    image: quay.io/prometheus/snmp-exporter
    volumes:
      - ./services/snmp-exporter:/etc/snmp_exporter
    ports:
      - 9116:9116
      - 116:116/udp
    restart: unless-stopped
    command: --config.file=/etc/snmp_exporter/snmp.yml

Result SNMP Exporter

snmpd -c /jffs/snmpd/snmpd.conf

Enabled SNMP instead in DD-WRT -> Services -> Services -> SNMP
