Bonita Engine Queriable logger

Queriable logger provides information about important events that happened in the Bonita Platform.

For Subscription editions only.


The queriable logger service provides information about important events in the Bonita Platform that are not directly related to execution of a process. The log includes information about administration operations such as deployment of a new process definition, commands, reporting, actor mapping, and organization and user management.

The Bonita Engine stores information in the queriable log. The information in the log is accessible using the LogAPI.

The information available from the queriable log is primarily for the platform and process administrator. It is not intended to be used as a notification system: avoid pooling on the queriable log. If you need to be notified of specific events, use the configurable event service.


Here is an example of how to search for log message about a specific activity:

final SearchOptionsBuilder builder = new SearchOptionsBuilder(0, 100);
builder.filter(LogSearchDescriptor.ACTION_SCOPE, aTaskId);
builder.searchTerm("Adding a new user");
builder.sort(LogSearchDescriptor.ACTION_TYPE, Order.ASC);
final LogAPI logAPI = TenantAPIAccessor.getLogAPI(session);
final SearchResult<Log> searchedLogs = logAPI.searchLogs(builder.done());
for (Log log : searchedLogs.getResult()) {
     // Print the detailed user creation message:

Implementation details

The queriable logger service stores log message in the Bonita Engine back-end database using the Hibernate library. The interface and the implementation of the service are available from the source code repository on GitHub.

Disabling the Queriable logger

Each queriable log type can be turned off individually with its associated property. The properties must be listed into the /setup/platform_conf/current/tenants/[tenantId]/tenant_engine/ file.

Find the list of properties

  • You can deactivate the logging on all the events listed here.

  • Or, you can also find a set of properties for each product version. You’ll find them in a java library: The bonita-tenant-sp.xml file contains the list of properties, and it is packed into the /server/webapps/bonita/WEB-INF/lib/bonita-server-sp-[BonitaVersion].jar file.

Disable the Queriable Logs

  1. Use the Platform configuration setup tool to pull the configuration on the disk: ./ pull

  2. Edit the /setup/platform_conf/current/tenants/[tenantId]/tenant_engine/ file.

  3. Add one line per property for each type of queriable log you want to disable, and set it to false, e.g.: bonita.tenant.queriable.log.ACTOR_CREATED.INTERNAL=false bonita.tenant.queriable.log.APPLICATION_PAGE_DELETED.INTERNAL=false

  4. Use the Platform configuration setup tool to push the configuration in the database: ./ push

  5. Restart the application server
