[arm-allstar] email alerts from our nodes

[Doug Crompton]

For those that want to experiment - here is a script that determines if any
of a group of nodes connected to a hub is in the connecting state. This
script will output nodes that are connecting and if there are no nodes
connecting. It mkes no attempt to do anything more than notify by text on
the screen but the script is annotated to show where you would call other
scripts or programs to send mail, text, voice announcement using Asterisk
etc. I will leave the alert method up to the user. The script is called
check_nodes.sh  It checks every 30 seconds. There is no reason to run this
more often and even once a minute or two would be fine. In its final state
it probably would be run in the background.

#!/bin/bash

# WA3DSP 12/2019
# Determine if a node is in connecting state.

if [ -z "$1" ]
   then
echo -e "\nEX: check_nodes.sh <node>\n"
exit
fi
hub_node=$1

while :
do
Connecting=0
asterisk -rx "rpt nodes $hub_node" > /tmp/nodes

values=$(tail -n+4 /tmp/nodes | tr , " ")

for X in $values
do
if [[ ${X::1} == "C" ]]
   then
       ((Connecting=Connecting+1))
       echo "Warning! Node ${X:1} in connecting state"
       # DO SOMETHING HERE LIKE SEND TEXT OR MAIL ABOUT WARNING
fi
done
if [ "$Connecting" == 0 ]
    then
        echo "No nodes in Connecting state"
        # DO SOMETHING HERE TO SHOW ALL CLEAR
fi
sleep 30
done
