OpenSearch PPL queries for observability logs and traces are written using a pipeline syntax to source datasets, filter by fields, and aggregate results. This reference provides command, function, and endpoint guidance for OTEL traces and indices.

PPL commands can aggregate and parse OpenSearch indices using built-in functions. You can apply search, stats, timechart, and parse commands against your observability data to produce aggregated results for dashboards and troubleshooting.

The best way to count spans per service using PPL is to source your OpenSearch indices and apply the stats command to aggregate the results. This skill provides practical examples for quickly constructing these pipeline queries.

PPL works with OTEL informed datasets in OpenSearch to enable observability query authoring. It supports field handling and usage patterns specifically tailored for searching and analyzing OTEL traces and log data.

To troubleshoot and optimize PPL query performance for OpenSearch observability, use the reference's practical examples to refine command syntax and field handling. This ensures efficient searches, stats, and timechart generation against large datasets.

PPL search and stats commands may return incorrect field results due to improper field handling or syntax errors in the pipeline. Use this reference to validate command usage, API endpoints, and parsing logic against your OpenSearch indices.
