Event script which triggers an action if interface(s) bandwidth utilization threshold is exceeded
Bwutil.slax is a proof of concept event script which compares ingress and egress byte counters for each interface specified as a script argument in event policy definition with previous readings stored in a file. If calculated bandwidth utilization for a time-period is higher than the configured threshold, then a syslog message is sent.
Installation
Change the highlighted logical interfaces in text editor to actual WAN/uplink IFLs:
..or add/remove WAN interfaces like this:
<arguments> {
<name> "wan3";
<value> "ge-0/0/7.15";
}Finally, copy(for example, using scp) the bwutil.slax to /var/db/scripts/event/ directory and enable the script file under [edit event-options event-script].
In case of two routing engines, the script needs to be copied to the /var/db/scripts/event/ directory on both routing engines.
