Internal Tables

Introduction

All Deephaven installations include several tables for the system's internal use. These internal tables are updated by various Deephaven processes, and contain details about the processes and workers. The schemas for these tables should never be changed by the customer as this will result in Deephaven failures. All tables are stored in the DbInternal namespace.

Just like other tables, authorized users can run queries against these internal tables. In a standard installation, a user can query entries related to their username, while a superuser can query all entries in a table.

Audit Event Log

The Audit Event Log (AuditEventLog) contains specific audit events from Deephaven processes. Each row contains details on one specific audit event.

Configuration

  • Any process that can write to the audit event log can override several configuration items. All configuration overrides should be based on the process name or main class name.
    • <process name>.writeDatabaseAuditLogs - if true, then audit event logs will be created; if false, then audit event logs will not be created
    • <process name>.useLas - if true, then the audit events will be written through the LAS; if false, then audit events will be written directly to binary log files
    • <process name>.useMainClassNameForLogs - whether to use the class name for log entries; if false, then the retrieved value from the process.name property will be used instead of the class name
  • RemoteQueryProcessor.logCommands - if workers are writing audit events, defines whether or not all received commands are logged. The default value is false.
  • LocalInternalPartition - if specified, defines the internal partition to which data will be written; if not defined, then a local partition based on the host name will be used

The following processes have the option of writing audit logs.

Persistent Query State Log

When a query worker is started or stopped, it goes through a series of state changes, representing the worker's status. Each state represents a specific condition, and every state change for every persistent query is stored in the Persistent Query State Log (PersistentQueryStateLog). Current states are also visible in the status column in the Query Configuration Deephaven console panel. States include:

  • Uninitialized - the query has no status as it has not been run
  • Connecting - the controller is connecting
  • Authenticating - the query is authenticating with the authentication server
  • AcquiringWorker - the dispatcher is creating a worker process for the query
  • Initializing - the worker process for the query is initializing
  • Running - the query worker is running (script query types only)
  • Failed - the query worker failed to start correctly; an exception should be visible
  • Error - the query generated an error
  • Disconnected - the query worker disconnected unexpectedly. This may occur, for example, if the JVM experiences an OutOfMemoryError, a Hotspot error (possibly caused by a buggy native module), or if the garbage collector pauses the JVM for longer than the heartbeat interval between the worker and dispatcher.
  • Stopped - the query stopped normally (Live Query (Script) query types only)
  • Completed - the query completed successfully [Batch Query (RunAndDone) query types only]
  • Executing - the query is executing [Batch Query (RunAndDone) query types only]

The Persistent Query State Log (PersistentQueryStateLog) contains every state change that has occurred for all persistent queries.

Process Event Log

The Process Event Log (ProcessEventLog) contains all log messages from processes. Currently, only query workers and query servers can write their logs to the Process Event Log.

Configuration

The following configuration parameters define the process event log configuration.

  • Any process that can write to the process event log can override several configuration items. All configuration overrides should be based on the process name or main class name.
    • <process name>.writeDatabaseProcessLogs - if true, then audit event logs will be created; if false, then audit event logs will not be created
    • <process name>.useLas - if true, then the audit events will be written through the LAS; if false, then audit events will be written directly to binary log files
    • <process name>.useMainClassNameForLogs - whether to use the class name for log entries; if false, then the retrieved value from the process.name property will be used instead of the class name
    • <process name>.logLevel - the minimum log level event which will be written. The default value is INFO. Allowed values are:
      • FATAL
      • EMAIL
      • STDERR
      • ERROR
      • WARN
      • STDOUT
      • INFO
      • DEBUG
      • TRACE
    • <process name>.captureLog4j - if true, any output sent to the Log4J logger is written into the process event log.
    • <process name>.captureSysout - if true, any system output is written into the process event log
    • <process name>.captureSyserr - if true, any error output is written into the process event log
    • <process name>.aliveMessageSeconds - if non-zero, a message is periodically written to the process event log indicating that the process is still alive
    • LocalInternalPartition - if specified, defines the internal partition to which data will be written; if not defined, then a local partition based on the host name will be used
  • RemoteQueryProcessor.sendLogsToSystemOut - if defined and set to true, tells the query workers to send their logs to standard system output. This can not be used when writing to the process event log.

The same set of processes that can write to the audit event log can write to the process event log.

The Update Performance Log (UpdatePerformanceLog) contains aggregated performance details on incremental update operations performed in the LiveTableMonitor loop.

Update performance logging allows three types of logging.

  • Log - the update performance data is printed to standard out
  • Listener - the update performance data is supplied to registered UpdatePerformanceTracker.Listeners; this can be used to programmatically handle the performance logs in-process. The Deephaven Console uses this functionality to provide the Live Table Monitor panel for examining the performance of client side query operations.

The mode is driven by the UpdatePerformanceTracker.reportingMode property, which can be set to the following values:

  • NONE
