For monitoring purpose we suggest three options:

1. Nagios monitoring integration 

   Device42 offers a Nagios plugin for Device42 which can be downloaded from this link Plugin Download, and allows easy monitoring of the health status of your Device42 appliance. Data returned includes:

   • Device42 Database Size
   • Appliance Disk space usage
   • Memory usage
   • CPU usage
2. Zabbix Integration which can be downloaded from this link Zabbix Download
3. API call to check the health status of the CPU/RAM, DB size and the status of recent backups

curl https://yourdevice42ipaddress:4343/healthstats/

/4242 port can be used if the SSL is disabled on Device42/
