Global Request Number

Generate a unique identifier for each request on the ​Akamai​ edge network.

How it works

When enabled, this behavior generates a unique identifier for each request on the ​Akamai​ edge network, for use in logging and debugging. Global Request Number (GRN) identifiers follow the same format as ​Akamai​’s error reference strings, for example: 0.05313217.1567801841.1457a3. You can use the Edge Diagnostics API’s Translate error string operation to get low-level details about any request.
