This page has been superseded by Tricheck, which performs similar checks of your environment. This page is likely to be deprecated in a future release.

Tricheck is available to Trifacta administrators through the application. See Admin Settings Page.

The Trifacta® platform publishes a set of diagnostics metrics for admin users. To review, login and navigate to the following URL:

NOTE: You must be an administrator to access this feature.

http://<host_server>:<port_number>/diagnostics

Status tab

Check the status on internal and external services of the Trifacta platform.

  • To download the log file for any service, click the Download link. 

    Tip: You can download all service logs at the same time through the application. See System Services and Logs.

  • To refresh status for any set of services, click the Refresh button.

Status Values:

  • RUNNING - The service is running. However, it may not be fully operational.
  • STOPPED - The service is stopped.
  • STARTING - The service is in the process of starting or restarting.
  • UNKNOWN - The service is not returning any status information.

Tip: Additional insights into why a service or status check has failed may be available in the Diagnostic Server log. See System Services and Logs.

Trifacta Services

Batch Job Runner

This service monitors and tracks job execution on the backend running environment.

Data Service

The Data Service is deployed when the Trifacta platform is able to read from and write to external datastores such as Hive.

Diagnostic Server

The Diagnostic Server performs user-triggered diagnostics tests on various components of the Trifacta platform and the backing data platform to verify health.

 

Java UDF Service

The Trifacta platform supports a Java-based UDF (user-defined function) service.

Machine Learning Service

This service is responsible for machine learning in the platform.

Proxy

The proxy service manages interactions between the Trifacta application and the client browser. 

Spark Job Service

This service manages the processing of Spark jobs. Spark integration must be enabled in the platform.

Supervisord Server

This server governs operations of all of the components in the Trifacta platformThe supervisord server starts and stops the other components in the system and (in production environments) restarts them if they crash.

VFS Service

This service runs the internal virtual file system, which brokers all calls to and from the file systems to which the platform is connected. This service is used when the Photon running environment is enabled.

Webapp

The WebApp service serves the front-end UI to users. 

External Services

Status information in this section pertains to services that are external to the Trifacta platform, including the backend data platform.

  • Hadoop MapReduce
  • HDFS
  • PostgreSQL Server

Tools

Coming soon!

Metrics

Disk Usage

Storage usage and availability on the Trifacta node.

  • For more information on available storage in the backend data platform, see External Services on this page.

Memory Usage

Memory usage and availability on the Trifacta node.

Batch Job Queue

Number of batch jobs queued for execution.

Diagnostics tab

Use the Diagnostics tab to run checks on the Trifacta platform and its integration with data storage and job processing services.

  • To execute any diagnostic test, click Run.

Kerberos

The Trifacta platform can be configured to integrate with Kerberos for authentication to the Hadoop cluster. See Set up for a Kerberos-enabled Hadoop cluster.

  • The Trifacta platform must have access to a Kerberos keytab file. See the previous link for instructions on creating the file.
  • If the Kerberos delegation token can be retrieved, then authentication is enabled.

Hadoop (General)

Click Run to acquire the Hadoop client configuration files from the Trifacta node.

HDFS

The Trifacta platform can interface with HDFS for data storage in a Hadoop cluster. These tests verify the platform's ability to interact with HDFS, which provides data storage and diagnostic information on the overall cluster.

Self-Checks

Use these tests to verify aspects of the Trifacta platform.

  • For more information on your software license, see License Key.
  • You can test for the presence of the JAR file for the distribution of the data processing platform in use. 
  • The configuration files are stored in the following directory: /opt/trifacta/conf

System Environment

These tests provide environment information for the node hosting the Trifacta platform. You may be asked to provide this information. See Contact Support.
