}Expand description
HostMetrics encapsulates the set of metrics emitted by the wasmcloud host
Fields§
§handle_rpc_message_duration_ns: Histogram<u64>Represents the time it took for each handle_rpc_message invocation in nanoseconds.
component_invocations: Counter<u64>The count of the number of times an component was invoked.
component_errors: Counter<u64>The count of the number of times an component invocation resulted in an error.
component_active_instances: UpDownCounter<i64>The number of active instances of a component.
component_max_instances: Gauge<u64>The maximum number of instances of a component.
system_total_memory_bytes: ObservableGauge<u64>The total amount of available system memory in bytes.
system_used_memory_bytes: ObservableGauge<u64>The total amount of used system memory in bytes.
system_cpu_usage: ObservableGauge<f64>The total cpu usage.
host_id: StringThe host’s ID.
lattice_id: StringThe host’s lattice ID.
Implementations§
Source§impl HostMetrics
impl HostMetrics
Sourcepub fn new(
meter: &Meter,
host_id: String,
lattice_id: String,
refresh_time: Option<Duration>,
) -> Result<Self>
pub fn new( meter: &Meter, host_id: String, lattice_id: String, refresh_time: Option<Duration>, ) -> Result<Self>
Construct a new HostMetrics instance for accessing the various wasmcloud host metrics
linked to the provided meter.
The refresh_time is optional and defaults to 5 seconds. This time is used to configure how
often system level metrics are refreshed
