<?php OpenSwoole\Server->stats(int $mode = \OpenSwoole\Constant::STATS_DEFAULT): string|array|false
The output format
If success, it returns an array of data, otherwise it returns false.
Notice: the metircs outputs since v4.9.0 has largely changed and much more metrics are supported.
Get the Open Swoole server metrics within your PHP framework or application.
Moving forward to support the Cloud Native ecosystem, OpenSwoole v4.9.0 started to support metrics in JSON and OpenMetrics formats.
You can observer and check the internal metrics of Open Swoole servers with open source Grafana and Prometheus.
There are three metrics output format supported:
\OpenSwoole\Constant::STATS_DEFAULT - PHP array\OpenSwoole\Constant::STATS_JSON - JSON format\OpenSwoole\Constant::STATS_OPENMETRICS - OpenMetrics formatThe array of metrics of the current Open Swoole server:
