Thank you @terrypacker. I had a global script using $EXEC
Once I removed that the script would execute.

I receive the error when validating the script in both the v3 and legacy UI.

I checked and on this particular instance of mango I had made the changes referenced here
https://forum.infiniteautomation.com/topic/4503/simple-ping-monitor
and here
https://forum.infiniteautomation.com/topic/3818/invoke-shell-commands-from-a-scripting-environment

Thanks @CraigWeb
I corrected that and continue to have the same error.

Hello,

This is related to Core 3.6.4 / Meta 3.6.2.

When attempting a simple script

var myTotal = (p1148.value + p1164.value + p1068.value + p22238.value);
return(myTotal);

I receive the following error that I was hoping someone could shed some light on -

ReferenceError: "$EXEC" is not defined at line: 23 at line: 23

Thank you

Hello,

After fresh Debian 10 Install I used the Install script provided on the IA site. https://help.infiniteautomation.com/install-script

When the script completed I was unable to start mango per the script instructions -

Info from journalctl -xe

I am able to start mango manually without any issues

Also, after the script install I now get the 2 errors highlighted below

Any suggestions as to how I can address this? Please let me know if I can provide any additional info.

Thank you -

Hello fishfacs,

I had a similar requirement in the past and Phillip provided the solution detailed here. Not sure if anything may have changed since then as its been a while. I hope this helps.

As always, thank you.
Works perfectly and I appreciate the link to the documentation.

$EXIT
This global object is used to store the exit code of the process. If the exit code is not zero, then the process failed.

Hello Phillip,

I had a chance to try this out and I do not seem to get a response when running the ping command (this is on a MangoES). I have verified shell access is available via scripts by running commands like the ones below where I receive a response.

var response = $EXEC("ls -l");
print(response);

var ip = $EXEC("ip a"); 
print(ip);

Can you confirm similar behavior? Is this a permissions issue?

Thank you.

In the Alphanumeric approach, would the scripting data point hold the host info (IP) and pass it to the data source script? Or are you suggesting the hosts be part of the script and the alphanumeric point is the trigger for a general alarm for any return of 1?

Thank you, Phillip.

After your response, I am thinking about a binary meta point per device with timer update event and change detector to monitor the device(s) online status.
