Domain Log Filter Guidelines
Domain log filters are divided into three groups: package related, security related and application connections. There are important guidelines you should consider when you are creating domain log filters, since certain combinations may not work as expected.
- The "OR" logical operator is used for the filters in same group. The domain log is generated only if there is at least one filter group allowing the subsystem, and no filter group disallowing it.
- A filter is applied only if the subsystem includes the corresponding column, and the column has a value when logging. For example, the operation filter in the package-related group can be applied for Application and Operation Replay; Application and DS Interface; and all Connection subsystems. If the operation has no value in the logging context when logging (which is possible for Application and DS Interface, and all Connection subsystems), the operation filter does not take effect.
- If one filter is not applied, the permission is neither allowed nor disallowed, and other filters (groups) determine whether to generate domain logs. If no filter group is allowed, the domain log is not generated.
For example, say a filter is set for
both operation and security:
- For subsystems that do not apply the operation filter—such as Data Sync, Cache Refresh and Device Notification—domain logs are generated only for security configuration filter matches.
- For the Operation Replay subsystem, domain logs are generated only for operations filter matches.
- For the DS Interface and Connection subsystems, domain logs are generated only for operation filter matches and null generated domain logs.
