Hey Skunks
Has anyone implemented successful BGP sessions monitoring with Nagios? Which plugin did you use and what were the configs?
What do you want to monitor specifically about the BGP sessions. There are a number of bgp neighbor states that can be monitored. The reason being one particular state is likely to give an unlikely picture of what the problem is. Each state is linked to a specific MIB and OIDs (specific to the equipment vendor). Therefore, the best way to go about this is to set snmp traps and use nagios to monitor the traps (snmp trap handlers). I don't have any configs to share however most of the plugin's that come with Nagios have the configuration settings. There are two types of plug-ins for BGP checking those that use the CLI to check the status and those that use the OID's. I would go with the OID's as they are very specific. For the Router settings here you need either to provide a username/password for CLI based plugins and an SNMP community/password for the SNMP OID based plugins. Look at the scripts to see what they are doing. If you are not on Vendor C. you will have to modify the scripts with the right OID's for them to work for you. HTH, Michuki.
