Gjallar is a new monitoring service that runs as a single static Go binary with YAML config and SQLite storage, using pure-Go drivers to avoid CGO and Oracle client libraries.

WHY IT MATTERS

For engineers monitoring a few dozen services, Gjallar avoids the operational overhead of a second distributed system. Its pure-Go Oracle driver removes the need to install Oracle client libraries on minimal boxes. The lock-free pipeline and hot reload make it easy to operate.

The three things worth knowing

Gjallar ships as one static Go binary, one YAML config, and one SQLite file.

It builds with CGO_ENABLED=0 using pure-Go replacements for PostgreSQL, Oracle, ICMP, and SQLite.

A single consumer goroutine owns all state and database writes, eliminating locks and surviving restarts.
