Hi there, I'm getting a weird error and I still don't know what is causing it.
I installed the plugin and it returns results but only in the terminal like this:
[root@localhost libexec]# ./check_mikrotik_mem -H 192.168.0.254
SNMP OK - Using 38% of the total 1894MB memory. | data=38

But in Nagios it's giving me this error:
(No output on stdout) stderr: /usr/local/nagios/libexec/check_mikrotik_mem: line 179: snmpget: command not found

But I have net-snmp-5.7.2.1 installed and the check_snmp plugin is working without any problems.

I just don't know why is giving me an error in Nagios but not in the terminal...strange

Hope you can help me, thanks in advance :)

Best regards
I also needed to update the OIDs in the script, thanks for cyberef for doing the leg work on this.

Works great but I had to change the OID values. I guess they changed it in the latest version.

memtotal=$(snmpget $community$authproto$authpassword$privpasswd$protocol$secname$seclevel$privproto -Oqv $Host .1.3.6.1.2.1.25.2.3.1.5.65536)

memused=$(snmpget $community$authproto$authpassword$privpasswd$protocol$secname$seclevel$privproto -Oqv $Host .1.3.6.1.2.1.25.2.3.1.6.65536)
