Help needed with mtr script in bash

[r00igev@@r]

I have this in a bash variable.

How do I create the logic for an if statement to send a webhooks message when the packet loss is not 0.0% or 100.0%?

It seems to be beyond my talent at this stage.

I assume you only want to get alerted if the destination has packet loss?

In this case, 1.1.1.2 ?

Nope, that would easier but I'm looking to report any packet loss along the path on a hop that reports it.

 

[Mr Scratch]

the logic would be so simple but not knowing the number of hops makes it tricky else I'd have run MTR counted n lines and worked from n to 0+2, awk'd the 5th col and done a line by line if or case

 

[Mr Scratch]

oh wait wc -l to get # of lines lol

then you know the first two are irrelevant

then proceed as above

can either set to notify if any hop is not within bounds set by check

or if aggregate isn't within the bound

I'm drunk

 

[Mr Scratch]

I'll give it a bash when I'm near my computer

 

[r00igev@@r]

I'll give it a try as well.

Here's a dirty one all on the same line

while true; do mtr -r -c10 -o L 1.1.1.1 > test.txt ; loss=($(cat test.txt | awk ' {print $3}' | awk -F. '{ print $1}' | tr -d [a-zA-Z%] )); for hop in "${loss[@]}" ; do if [[ $hop > "0" ]] ; then echo "Packet loss of $hop occured" ;fi; done  ;done

I'd make it nicer but I have work to do
