Struct MetricsHandle 

Source 
pub struct MetricsHandle { /* private fields */ }
Expand description

Handle to the installed exporter. Cheap to clone.

Implementations§

Source§

impl MetricsHandle

Source

pub fn render(&self) -> String

Render the current exposition-format snapshot (empty for the no-op exporter).

Source

pub fn render_fn(&self) -> Arc<dyn Fn() -> String + Sync + Send> ⓘ

The render function seam handed to the admin server, keeping it independent of exporter internals.

Source

pub fn upkeep_tick(&self)

One maintenance tick: drains histogram state and refreshes process metrics. Cheap; call on an interval.

Source

pub fn spawn_upkeep(&self, period: Duration) -> JoinHandle<()>

Spawn the periodic upkeep task on the current tokio runtime.
