I'm now using Email Security Gateway 300 and I planning to monitor its system status by some kinds of monitoring app (e.g. Nagios, Zabbix, etc.)
I know SNMP only available start from model 400 and up. As the monitoring apps also support monitor through provide the ssh / telnet credential. Is model 300 can login through ssh / telnet ?
If none of them available. Any way I can monitor the system status ?
