Control of agent functions

The functions of the Python application server are controlled.

• enabled Boolean

  Default true

  All functions are enabled. Even when the value is false, the minimum data to maintain communication with the server is sent.

• counter_enabled Boolean

  Default true

  The performance counter tracing is enabled. The performance counter includes data such as active transaction, user, CPU, memory, SQL, and outbound HTTP call. It is ignored when the enabled value is false.

• stat_enabled Boolean

  Default true

  The statistics tracing is enabled. Statistical data such as transactions, SQL queries, outbound HTTP calls, user agents, and client IPs is collected every 5 minutes, but now the collection is stopped. It is ignored when the enabled value is false.

• active_stack_enabled Boolean

  Default true

  Enable the active stack tracing.

  Note

  If the counter_enabled value is disabled, the active stacks are not collected because no active transaction data is collected.

• eactive_stack_second Seconds

  Default 10

  Set the interval for tracing the active stacks.

  Caution

  It is not recommended changing the value.

• realtime_user_thinktime_max MiliSeconds

  Default 300000

  Set the maximum call interval credited by the same user when measuring the number of real-time users.

• time_sync_interval_ms MiliSeconds

  Default 300000

  Set the synchronization interval between the agents and the server. For no synchronization, set it to 0.

• realtime_user_thinktime_max Int

  Default 0

  The WhaTap agent does not transmit the text data once sent until the next day again because it is hashed. If a value is set different from the previous setting, the data is sent again.

  Note

  Transaction URLs and SQL strings correspond to text data.

• ignore_instrumentation_set List

  Default [] (empty list)

  Specifies libraries or categories to exclude from automatic instrumentation, separated by commas (,). At agent startup, matching entries are skipped during the import hook registration phase, so instrumentation is not installed for those libraries. Use this when a specific library causes side effects or when you want to exclude it from instrumentation targets.

  There are three matching rules. If any one matches, the library is excluded from instrumentation:

  Specification method	Example	Effect
  Full category.library key	database.redis	Excludes only that one key
  Category only	database	Excludes all database.*
  Library name only	redis	Excludes keys matching that name

  whatap.conf

  ignore_instrumentation_set=httpx,redis,application.django

  Case and surrounding whitespace are normalized before comparison. Even if the trace_logging_enabled option is enabled, if logging is included in the list, logging instrumentation will not be applied.

  Note

  WhaTap Python agent version 0.2.0.3rc1 or later is required.
