Create shell script
touch trunk.sh
Add the content to the script
#!/bin/bash
serviceIsRunning=false
var1=$(/usr/sbin/asterisk -rx "sip show peers" |grep trunk_name |awk '{print $6}'| sed 2,2d)
var2=$(echo $data | awk '{print $2}')
if [ "$var1" == OK ]
then
serviceIsRunning=true
echo "0:200:running"
fi
if [ $serviceIsRunning == false ]
then
echo "2:404:UNREACHABLE"
fi
Save the script and make it executable
chmod +x trunk.sh
Try to run it
./trunk.sh
Go to the PRTG, and add the SSH Script sensor to the device
In the «Script» field choose trunk.sh and SAVE
! Make sure your PRTG Server has access to Asterisk Server, if not, add root username and password
to the credentials in the BASIC DEVICE SETTINGS

Try to start Eth0 device
# ifup eth0
Device eth0 does not seem to be present, delaying initialisation
To Solve this :
Delete networking interface rules file so that it can be regenerated and reboot your CentOS system.
# rm /etc/udev/rules.d/70-persistent-net.rules
# reboot
New Mac address has been generated:
# This file was automatically generated by the /lib/udev/write_net_rules
# program, run by the persistent-net-generator.rules rules file.
#
# You can modify it, as long as you keep each rule on a single
# line, and change only the value of the NAME= key.
# PCI device 0x8086:0x100e (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="08:00:27:fe:c1:03", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
Now edit /etc/sysconfig/network-scripts/ifcfg-eth0,
Add new HWADDR generated or remove it
Remove UUID line
Restart the networking service
# service network restart

By default, a MySQL installation has an anonymous user, allowing anyone
to log into MySQL without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
Remove anonymous users? [Y/n] y
... Success!
Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n] y
... Success!
By default, MySQL comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n] y

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

All done! If you've completed all of the above steps, your MySQL
installation should now be secure.
Thanks for using MySQL!
