We have trouble configuring notification alerts for our bandwidth monitoring services for our Cisco switches for the cases where we want to get a critical or warning alert when bandwidth goes below a threshold.
An example:
According to https://nagios-plugins.org/doc/guidelines.html, if want Nagios to trigger a warning notification when input bw goes below 62 Mbps and a critical notification when it goes further down below 50 Mbps, we have to use a check command like this:
check_xi_service_mrtgtraf!192.168.xxx.xxx_10101.rrd!62.0:,500.0!50.0:,800.0!M!!!!
This is how input/output gauges look like in this case and when input bw is ~60Mbps:

Although current input bw is within the warning range, service state remains in the OK state:

We've tried several different combinations of the alert tresholds, but we couldn't manage to have a state other than OK.
Are we missing something here?
Thank you in advance.
