In Trace0, a Transaction represents a single end-to-end trace across all services involved in handling a request — such as an inbound HTTP request, a message consumed from a queue, etc. You can view the list of transactions for each of your services in the Transactions section: Transactions Light

Filtering and Searching

You can filter transactions by service, time period, or using the Errors only toggle. You can also search transactions by free text, returning any transactions where the search term appears in the transaction’s log entries: Transactions Light
