Transaction Logging

The Transaction Logging dashboard provides the capability to review, monitor, and investigate logged transaction data in near real-time. One of its most essential features is the Discover tab, which allows users to explore log data, filter results, and gain deeper insights into system operations such as transaction logging.

This article covers how to use the Discover tab for analyzing data, saving queries, and customizing your view to meet your specific needs. The Discover tab is a core feature of Transaction Logging that enables users to:

Explore raw data stored in OpenSearch indices.
Query and filter log data with precision.
Visualize trends and identify patterns in real-time.
Save frequently used searches for quick reference.

Select an Index Pattern

This feature is especially useful for investigating graph executions, troubleshooting errors, and monitoring metrics. To access the Discover tab:

Log in to OpenSearch Dashboards using your SSO credentials.
User access to Transaction Logging will not be available at the time of the 25.1 release. It will be enabled shortly after. For access-related queries, please contact your CSG Customer Success Team representative.
From the top left-hand side navigation menu, select Discover.
Select the relevant index pattern from the dropdown to access and query the data you need. For Example: transaction logs.

Analyzing Document Tables

In the Discover tab, log data is shown in a Table format by default. To dive deeper into a specific document:

Switch to JSON view to inspect the full raw metadata and field values.
Use View surrounding documents to explore log entries that occurred just before or after the selected event, helpful for troubleshooting sequences of actions.
Select View single document to focus on one log entry in detail without distraction.

These options make it easier to trace events, debug issues, and understand data context. For full details, see the Transaction Logging - Analyzing Document Tables.

Filtering data

Filters allow you to narrow down your search results by specifying specific criteria. You can filter by field, value, or range. The Add filter pop-up helps by suggesting available fields and appropriate operators.

To apply a filter:

Below the DQL search bar, select Add filter.
Choose values from the Field, Operator, and Value dropdowns. For Example: Select Stream - is - stdout.
Click Save to apply the filter.

To remove a filter, click the cross (×) icon next to the filter name. The filtered results will appear in the table, as shown in the following image. For full details, see the Transaction Logging - Filtering data.

Saving a Search

You can save your current search configuration, including the query text, applied filters, and selected data view for easy access later.

To save a search filter:

Click Save in the upper-right toolbar.
Enter a title for your search and click Save.

To access a saved search filter:

Click Open in the upper-right toolbar and select from your list of saved searches.

This helps you quickly return to frequently used searches without reapplying filters or rewriting queries

Visualizing Data Findings

To visualize specific field data from the Discover tab:

Click the inspect icon (🔍) next to the field you want to visualize. The data preview for that field appears.
Select the Visualize button. This will launch the Visualize application and generate a default visualization based on the selected field.

Best Practices

Only data within the configured retention period (30 days) will be available for review in OpenSearch Discover.
Use specific filters and queries to minimize large data sets and improve performance.
Saved searches can be leveraged for creating custom visualizations in the Visualize or Dashboard tabs.
