Example: Use digidevice.cli with digidevice.device_request
In this example, we will use the digidevice.cli module in conjunction with the digidevice.device_
request module to return information about multiple devices to Remote Manager.
1. Create a Python application, called showsystem.py, that uses the digidevice.cli module to
create a response containing information about device and the device_request module to
respond with this information to a request from Remote Manager:
from digidevice import device_request
from digidevice import cli
import time
def handler(target, request):
return cli.execute("show system verbose")
def status_cb(error_code, error_description):
if error_code != 0:
print("error handling showSystem device request: %s" % error_
description)
device_request.register("showSystem", handler, status_callback = status_
cb)
# Do not let the process finish so that it handles device requests
while True:
time.sleep(10)
2. Upload the showsystem.py application to the /etc/config/scripts directory on two or more Digi
devices. In this example, we will upload it to two devices, and use the same request in Remote
Manager to query both devices.
See Configure scripts to run automatically for information about uploading Python
applications to your device. You can also create the script on the device by using the vi
command when logged in with shell access.
3. For both devices:
a. Configure the device to automatically run the showsystem.py application on reboot, and
to restart the application if it crashes. This can be done from either the WebUI or the
command line:

i. Log into Digi Remote Manager, or log into the local Web UI as a user with full Admin
access rights.
