radar
radar is an agentless diagnostic data collection tool for PostgreSQL and for the system that hosts it.
radar collects a snapshot of system and PostgreSQL diagnostic data for troubleshooting and analysis. radar runs system commands and PostgreSQL queries, and streams the output into a timestamped ZIP archive. A PostgreSQL connection is optional; without one, radar collects system data only. When a command, file, or view is unavailable, radar skips that collector and continues the run.
pgEdge publishes radar as RPM and DEB packages and as pre-built binaries for Linux and macOS, so you do not need to build radar yourself. The Installing radar section describes each method, starting with the simplest.
