Telemetry log for Moodle

Keeps track of some basic process state to aid with diagnosis of performance problems on Moodle sites.

---

Installation

1. Clone this directory into /local/telemetry.
2. Execute the Moodle upgrades.

Patch the configuration file

Add the following lines to /config.php to allow the telemetry plugin to initialise early on in Moodle's setup:

// Register the telemetry plugin's shutdown function
require_once __DIR__ . '/local/telemetry/locallib.php';
local_telemetry_init();

Debugging tip

It's easier to debug exceptions thrown during database transactions if you place a breakpoint inside shutdown_manager::shutdown_handler()'s try {} catch {} block.
