Installing radar

radar runs on Linux and macOS as a single static binary. You can install the pgEdge package, download a pre-built binary, or build radar from source.

Reviewing the Requirements

The requirements for radar include:

  • a Linux or macOS host; radar uses standard utilities such as df and ps when they are present.
  • PostgreSQL 12 or later; some collectors require a later version, as the data reference notes.
  • Git and Go 1.26.10 or later for a build from source; the go directive in go.mod sets this minimum.

Understanding Platform Differences

Some system collectors are specific to one platform. On macOS, radar skips the Linux-only collectors for systemd, SELinux, and the /proc and /sys filesystems. radar uses macOS collectors such as sysctl, system_profiler, diskutil, and launchctl instead.

On macOS, Homebrew can install PostgreSQL if the host needs it:

brew install postgresql@18
