Hi . Great job. My Server went down due to power surge; I realize I could not start my already configured Nagios. Do I need to start installation again or a particular service need to be started? Mind you i set up my Nagios on CentOS 07.

hi, where I can get the MIBS you show? I don't mean about "MIB browser" I have it, i just want to get the mibs from cisco but it is many and also need cisco account.

[@ballamoussadoumbouya8175]

For the supervision of the bandwidth which sorts at the level of the interface of your router, why did you take the information from the MIB of ifOutOctets.1? why you didn't take for ifOutOctets.2 or for ifOutOctets.3 for example? thank you for explaining to me please

[@yaznelita1]

because it originally defined interface 1, you can work with variables from interface 1
