Troubleshoot abnormal device behavior
If your device suddenly stops communicating with your server, or behaves abnormally, using Peek to capture packets will allow you to inspect the network traffic between cellular and IP networks and understand whether a problem occured on the device or cellular network (if a packet never arrived), or afterwards (if a packet arrived but doesn’t make it to your server)
Debug network architecture
When building your application, there are many parts of its network architecture to check, such which transmission protocol the device uses, what servers the device connects to, and whether or not data is encrypted. Using Peek to capture packets will allow you to perform detailed analysis to verify that your device is behaving according to your design
Identify the source of high data usage
While Soracom’s SIM management tools let you easily check the data usage of each SIM, you can only check how much data was used, not what the data usage was for. By capturing packets with Peek, you can quickly find out what requests your device is making, and which servers it is communicating with
Improve security
Similarly, your application may have strict requirements to ensure that data is not sent to an unauthorized destination. Peek will allow you to perform an audit of your device and check for any packets that are being sent to an unrecognized server. You can then update the Outbound Filter setting of your VPG to quickly block these unauthorized requests.
