after resin.io is finished downloading the application, or when restarting the gateway, it most likely means the `GW_RESET_PIN` you defined is incorrect. Alternatively the problem can be caused by the hardware, typically for the `IMST iC880A-SPI` board with insufficient voltage, try another power supply or slightly increase the voltage.

# Device statistics
|
||||
If you want to show nice looking statistics for your gateway(s) there are a couple of additional steps to take. First,
|
||||
copy Dockerfile.template.metering to Dockerfile.template . Next copy start.sh.metering to start.sh . Now use the instructions above to
|
||||
update the resin image.
|
||||
|
||||
Once the new image is deployed, go to the resin.io dashboard for your devices and select 'Enable Public device URL' in the drop down menu
|
||||
(the one to the right of the light bulb). That is all that is required to provide metrics. Now you will need to install a metrics collector
|
||||
on a seperate system as outlined in [Fleet-wide Machine Metrics Monitoring in 20mins](https://resin.io/blog/prometheusv2/)
|
||||
|
||||
(To show packet forwarder graphs you need to add your own graphs to the provided templates)
