Mikrotik Script: Alert on queue tree limit exceeded

Hi guys,

This is my first post here, I’m a Network Engineer who works a lot with Mikrotik devices and Server Administration and you can see more of my posts on my website. I found this blog some time ago and was invited to contribute with some of my own scripts that may help others!

Today i’ll show you a little script for RouterOS to check if queue tree exceed the limit you set.

For. Example I’ve got a queue tree that limits the amount of total traffic (Upload+Download) to 50Mbps.

I want to know whenever this queue exceed the limit, and I want the system to send me an email.

This is the script:

:global checkrate [/queue tree get total-traffic rate]
:local limit 50000000

:if ( $checkrate < $limit ) do={
:log info ("Queue not Exceeded")
}
:if ( $checkrate > $limit ) do={
:log info ("Queue Exceeded")
/tool e-mail send server=xxx.xxx.xxx.xxx from="me@myself.com" to="me@myself.com" subject=("Queue Limit Exceed") body=("Queue Limit Exceed, Limit is: " . $checkrate)
}

Enjoy!
