Debug is a tool for troubleshooting and monitoring API proxies running on Apigee. The Debug tool
lets you probe the details of each step
through an API proxy flow.
Apigee lets you collect debug data, which shows the entire request/response flow of your
API proxies. This includes all request/response parameters along with transformations applied to
them at policy execution time. This is important for debugging and troubleshooting during API proxy development and deployment.
Debug data collection and transmission
Apigee gateway nodes collect debug session data and cache it internally,
before transmitting that data to the control plane in the Cloud. From there it
is shared to the debug session UI, for operators to analyze.
If you use Debug masking,
Apigee performs the masking in the gateway nodes, before transmitting the debug data to the
control plane.
Using Debug
Create and manage debug sessions using the Debug tool using the UI or API, as described in
Using Debug.
Alternatively, you can download debug sessions and view and analyze them offline, as described in
Using Offline Debug.
Apigee Support use of Debug
Only customers can trigger a debug session, but Apigee Support can access non-deleted past debug sessions
during the course of a support case to help troubleshoot proxy-specific issues.
Note the following:
Apigee Support has read-only permission to Debug data.
Apigee Support may request that you run a debug to capture information about an
issue, and that you provide the debug session ID or a link to the debug session so
that Support may review the captured debug. Since saved debug sessions are valid for
only 24 hours, we recommend that you download the debug session and attach it to the
case opened with Support to enable offline viewing.
For Apigee hybrid users
If you are using Apigee hybrid, review the following sections.
Debug architecture
The following illustrates the process of creating a new debug session:
Debug data is persisted in the management plane for up to 24 hours.
