SSH script for asterisk

Votes:

0

Hi, i need to check that asterisk trunk is active. I need to make 30 sensors with different trunk names. I ended up with such ssh script: #!/bin/bash var1=$1 if [ "$var1" == OK ] then echo "0:200:running" else echo "2:404:UNREACHABLE" fi

and i give this parameter to prtg "/usr/sbin/asterisk -rx "sip show peers" |grep 9859204943 |awk '{print $7}'| sed 2,2d"

What am i doing wrong? if i making script like this: #!/bin/bash var1=$(/usr/sbin/asterisk -rx "sip show peers" |grep 9857617234 |awk '{print $7}'| sed 2,2d) if [ "$var1" == OK ] then echo "0:200:running" else echo "2:404:UNREACHABLE" fi

Everything is working fine, but in this case i need 30 different scripts, i need somehow to fill "Number" 9857617234 in the sensor parameters.

asterisk gsm ssh-script

Hey kmorozov,

Please try to use the following script:

#!/bin/bash
value=$1
var=$(/usr/sbin/asterisk -rx "sip show peers" | grep ${value} |awk '{print $7}'| sed 2,2d)

if [[ $var == OK ]]; then
 echo "0:200:running"
else
 echo "2:404:UNREACHABLE"
fi

Does it work?

Hey kmorozov,

Thank you very much for your KB-posting.

Please try to use the following line:

var1=$(/usr/sbin/asterisk -rx "sip show peers" |grep $1 |awk '{print $7}'| sed 2,2d)

instead of 

var1=$(/usr/sbin/asterisk -rx "sip show peers" |grep 9857617234 |awk '{print $7}'| sed 2,2d)

That way, you only need to commit the number "9859204943" as parameter in the sensor settings in PRTG.

Best regards,
Sven

Thank you very much for reply, when I'm doing as u advised prtg always show error message, which means that script doesn't receive parameter. Maybe there is another way to make it without var1=$, or maybe I need to commit somewhere in the script.

No, only errors again. Maybe it because its value in value?

Probably - when you run it manually, write $value to the console as well so you can see the actual value. Probably the wrong column is selected via awk or sed?

If I run script via console like this:

#!/bin/bash
value=9859204943
var=$(/usr/sbin/asterisk -rx "sip show peers" | grep ${value} |awk '{print $7}'| sed 2,2d)

if [[ $var == OK ]]; then
 echo "0:200:running"
else
 echo "2:404:UNREACHABLE"
fi

I receive 0:200:running as it should be, maybe some sensor settings is wrong ?

Could you execute the script like this: ./script.sh 9859204943

Remember to configure value to be $1 instead of the current numerical value. Same result?

Same, it works fine: 0:200:running

So that means that the script sensor doesn't provide the correct value as parameter. Could you post the sensor config, specifically the parameter field?

I found the problem, in parameter field was "9859204943", it worked with '9859204943'

The parameters in Bash don't work like this. Could you evaluate the issue further? What problem does the Sensor message disclose?
