check_snmp. Multiply or divide the obtained value

Postby kchiche18 » Tue Jan 11, 2022 3:15 pm

Good afternoon.
I need to multiply by 0.1 a value obtained with the check_snmp plugin. I have seen that there exists in the source code of Github https://github.com/nagios-plugins/nagios-plugins/blob/master/plugins/check_snmp.c, a parameter:


I need to send to "check_snmp" a parameter (for example, -M 0.1) to multiply/divide the value recibied.
How can I do it?

I think to patch "check_snmp" something like this below, comment the constant and substituing by 'M' parameters.
