}

One periodic resource-usage sample emitted by Runtime::stats_stream.

Mirrors the union of fields exposed by Docker’s /containers/{id}/stats endpoint and Linux cgroup stat files so downstream consumers (autoscaler, docker stats-compat HTTP shim) can read a single shape regardless of backend. Counters that the runtime cannot report are left at zero — missing data is signalled separately via the surrounding stream metadata.

Fields

cpu_total_ns: u64

Cumulative container CPU time consumed, in nanoseconds.

cpu_system_ns: u64

Cumulative system CPU time observed at the same moment, in nanoseconds. Used to compute relative CPU percentage between successive samples (Docker’s classic cpu_delta / system_delta formula).

online_cpus: u32

Number of CPUs currently online for this container. Used as the final scaling factor in the CPU-percentage calculation.

mem_used_bytes: u64

Resident memory currently in use, in bytes (cgroup memory.usage_in_bytes minus inactive page cache for v1, or memory.current for v2).

mem_limit_bytes: u64

Memory limit configured on the container, in bytes. 0 when no limit is set (cgroup reports its sentinel value).

net_rx_bytes: u64

Cumulative bytes received across all attached network interfaces.

net_tx_bytes: u64

Cumulative bytes transmitted across all attached network interfaces.

blkio_read_bytes: u64

Cumulative bytes read from block devices.

blkio_write_bytes: u64

Cumulative bytes written to block devices.

pids_current: u64

Number of process IDs currently running inside the container’s pid namespace.

pids_limit: Option<u64>

Configured pids limit, if any. None means unlimited.

timestamp: DateTime<Utc>

Wallclock time the sample was taken.
