Troubleshooting Commands¶
Get worker Application Logs¶

# Replace 256000 with the maximum number of bytes you want to display
--limit-bytes=256000

cmd="some_command --option1 value1 --option2 value2"
# Next, we want to execute the command stored in the cmd variable.
# By using the ${} notation, we can reference the value of the variable.
