Is there an SNMP Manager for an OpenWRT router?

Question

linux

Good afternoon, the situation is this: there is a router on which the openwrt firmware is assembled, you need to monitor its status, and do it from any network. The SNMP agent is installed in the firmware, I can monitor, knowing the equipment address. I also need to install in the firmware for the router some kind of SNMP manager that would poll itself and send the data to a given server.
Are there any suggestions on how this can be done?

Answer 1

I also need to install in the firmware for the router some kind of SNMP manager that would poll itself and send the data to a given server.

The SNMP manager cannot "poll itself". The manager's function is only to query OIDs (variables) under the control of the SNMP agent/subagent .
And for "sent to a given server" there is a completely different SNMP mechanism: trap / info.
You will study the operation of SNMP carefully and you will be happy.
(and it's better to do this according to the net-snmp project, and not according to all sorts of fairy tales)
See SNMP protocol in POSIX operating systems , SNMP management

Answer 2

configure the ladders on the router, tell it the community and the server address. Well also lift the server any. For example, PRTG or Zabbix can be deployed on a virtual machine if you cannot allocate hardware.
And as Oleg wrote, the architecture of the SNMP protocol and solutions should be studied before asking questions :)
