Agent and IDS/Protocol/Task Script Compatibility

This release of the Tetra Empower Agent has changes that impact the Tetra Empower intermediate data schemas (IDS) and their parsers. Using this version of the Tetra Empower Agent with an incompatible or older version of the protocol and IDS will break your pipelines.

Please make sure that you have the compatible versions of the Tetra Empower IDS parsers and update the pipelines and processes to use the new protocols and IDS, so that pipelines continue to work as expected. For more information about the compatible IDS, protocol, and task script versions, see the Tetra Empower v5.x.x release notes

This page describes how a system administrator can install the Tetra Empower Agent and verify the system integration.

Before you can run the Tetra Empower Agent, you must do the following:

• Create a Tetra Empower Agent in the Tetra Data Platform (TDP)
• Set up the data connection
• Make sure that you have the required hardware, software, and user account credentials

For more information about all of the features and configuration options for the Tetra Empower Agent, see the Tetra Empower Agent User Manual (Version 5.2.x).

📘

NOTE

To restrict access to the local Tetra Agent Management Console, you can edit the Agent’s installation folder’s permissions to grant least privilege access. For more information, see Restrict Access to Agent Installation.

Set Up the Data Connection

The Tetra Empower Agent generates RAW JSON files that are uploaded to the TDP either directly or through a Data Connector. Before you install the Tetra Empower Agent, you must set up the agent's data connection to the TDP by using one of the following methods:

• On-Premises—requires the use of a Tetra Hub.

  -or-

• TDP (No Connector)—allows the Agent to upload source data directly to the TDP or Amazon Simple Storage Service (Amazon S3).

For more information about each data connection option, see see Agent Deployment Options.

Hardware and Software Requirements

To install and run Tetra Empower Agent v5.2.x, the following hardware and software versions are required:

• One of the following Microsoft Windows versions:
  • Windows 10 Enterprise or Professional, 64-bit
  • Windows Server 2016 Standard or 2019 Standard
• .NET Framework 4.8
• 16 GB RAM at minimum (64 GB RAM is recommended)
• 8 Core CPU
• Minimum 150 GB of free disk space
• Empower 3 Service Release 2 (SR2) or higher Client Software (English Edition)
• If installing Empower software on an English-language computer, make sure that you confirm that the Windows region settings are configured for English (United States). The symbols for English (United States) use decimal formatting, not comma formatting, which is important when displaying numeric values (12.56, not 12,56).

📘

For files produced by Empower, the limit is approximately 2.5 GB for a RAW JSON file.

🚧

Empower 3 Client Software

You must install the Tetra Empower Agent at the same workstation where the Empower 3 Client Software is running. The Tetra Empower Agent is compatible with Empower 3 Service Release 2 (SR2) or higher. If the Empower 3 Client version is earlier than SR2, then you must upgrade the Empower 3 Client software. For detailed system requirements, see the Client Software section in the Empower 3 System Administrator Guide.

User Account Credentials

To run the Tetra Empower Agent, you need the following valid user account credentials:

• Empower DB User account provides access to the Empower database through the Empower Toolkit.
• Empower Oracle TNS Names details provides access to the Empower database through the Empower client (the required information can typically be found in the <Oracle Client Install folder>\\network\\admin\\tnsnames.ora file in the Oracle folder of the Empower client machine).
• Group User account runs the Tetra Empower Agent and accesses the Empower file server.

Projects available for extraction from the Tetra Empower Agent depend on the access permissions of the EmpowerDB User account. The Oracle Transparent Network Substrate (TNS) Names' details are used to extract the date fields in a consistent ISO format.

You must ensure that the Group User account that runs the Tetra Empower Agent is part of the Empower User Group in the Active Directory Organization Unit, and has the same privileges as the standard Empower User which requires a read-only permission to access the Empower Raw data on the Empower File System. Furthermore, this account needs to have the following privileges from Empower and Windows.

• The Group User account should have the permission of Empower View Audit Trail to detect the Injection changes.
• The Group User account should have Windows Log on as a service permission to run the Agent as Windows Services program.
• Always verify the date time and decimal format settings of the Group User’s Windows Profile to ensure they match the settings from the current login user configuring the Empower Agent.
