Error in 'sendalert' command: Alert script returned error code 2.

[katshima]

I am generating alarms by acquiring abnormal values for CPU usage of NW devices.
I would like to send these alarms via email or webhook, but I get the above error and cannot send them.

What is the cause?

You can search the internal Splunk logs to see if there are any errors logged. If you run this what do you get?
