Add push_to_gateway() and delete_from_gateway() for manually pushing metrics to a Prometheus Pushgateway instance.
Histogram metrics now have a built-in time() method for collecting observations on the duration of an expression.
The built-in process_cpu_seconds_total metric is now correctly reported as a Counter instead of a Gauge. This fixes an inconsistency with other Prometheus clients that would prevent metrics being used with Pushgateway.
register_default_metrics(). Previously, this would include the total elapsed time for the process (as opposed to the CPU time that was actually used).Initial release. openmetrics is an opinionated Prometheus and OpenMetrics client for R.
Automatically instrument Plumber apps with register_plumber_metrics() and Shiny apps with register_shiny_metrics().
Collect default metrics with register_default_metrics().
Create custom metrics with counter_metric(), gauge_metric(), and histogram_metric() and custom registries with registry().
Write metrics in the OpenMetrics/Prometheus text format to any location with render_metrics().
