Nagios Support Forum

I am having multiple connections with ISPs and I am trying to use Nagios to monitor the connections. Currently, I am using Ping and DNS to monitor the connection but It seem not sufficient. 1. Ping to public website like Yahoo, Facebook and Google 2. DNS check resolve of Yahoo, Facebook and Google W...

the "-w" checks for high threshold like if my interface is 100Mbps and the traffic is nearly 100Mbps (let say >80Mbps) then nagios will trigger WARNING. BUT my purpose is to monitor low threshold like if traffic is low to <10Mbps, then nagios trigger WARNING.

I think with check_snmp_netif, i can get all interface statistic but i can not set the low threshold. Which option to set WARN when low threshold is met?

I am going to monitor cisco switches/routers. so, i can not use vnstat command. any other plugin?

I am currently looking for a plugin which can alert when the bandwidth of an interface is low in certain threshold.
Anyone know ?
