HTTPC, API Call

The following explains how to set options for the Java agent to collect and analyze data for HTTP outbound calls and API calls. Various options for fine monitoring are provided such as TOO SLOW error handling, CPU and memory usage tracing, stack trace recording upon each call, and URL normalization. This allows developers to efficiently manage their applications' external dependencies and identify performance issues.

• profile_error_httpc_time_max Int

  Default 10000

  If the HTTPC execution time exceeds the set value, it is treated as TOO SLOW error. If it is set to 0, it is not treated as an error.

• profile_httpc_resource_enabled Boolean

  Default false

  When collecting HTTP call steps from the transaction trace, the CPU and memory usages in the step is traced.

• profile_position_httpc Boolean

  Default false

  It records the stack traces at the execution time of HTTPC.

• trace_httpc_normalize_enabled Boolean

  Default true

  It enables the function to parse and normalize HTTPC URLs for transactions.

• trace_httpc_normalize_urls String

  Set the HTTPC URL patterns to normalize. It deletes the path parameter after parsing the call URL patterns.

  Note

  For example, if declared as /a/{v}/b, a/123/b is replaced by a/{v}/b. For multiple values, use comma (,) as the delimiter. A complement is required after arranging substitution patterns.

• hook_httpc_patterns String

  Set the full package class name.method for HTTP outbound calls. Register and use the full path of the method that performs HTTP calls. After registration, you need to redefine the class or restart the agent.

  whatap.conf

  hook_httpc_patterns=io.home.test.baseapp.app.post.service.HookHttpcService.*
  Note

  • To register multiple classes, use comma (,) as the delimiter.

  • Only asterisk (*) can be used as the wildcard, regular expressions cannot be used.
