Global fabric metrics registry.

Tracks system-wide counters and gauges for lease lifecycles, data-plane operations, and graph rewrites. Access the process-wide singleton via FabricMetrics::global().

Examples

use grafos_observe::FabricMetrics;

let m = FabricMetrics::global();
m.leases_total.inc();
m.leases_active.inc();
m.ops_total.add(5);
m.bytes_read.add(1024);
m.op_latency.observe(300);

Fields

leases_active: MetricGauge

Currently active leases (gauge — goes up on acquire, down on drop/expire).

leases_total: MetricCounter

Total leases ever created (counter).

leases_expired: MetricCounter

Total leases that expired (counter).

leases_fenced: MetricCounter

Total leases that entered fenced state (counter).

ops_total: MetricCounter

Total data-plane operations completed (counter).

ops_errors: MetricCounter

Total data-plane operations that failed (counter).

bytes_read: MetricCounter

Total bytes read across all data-plane operations (counter).

bytes_written: MetricCounter

Total bytes written across all data-plane operations (counter).

rewrites_total: MetricCounter

Total graph rewrites initiated (counter).

op_latency: MetricHistogram

Histogram of operation latencies in microseconds.

leases_revoked: MetricCounter

Total leases explicitly revoked (counter) — distinct from expired.

bind_latency: MetricHistogram

Histogram of lease bind latency in microseconds.

renew_latency: MetricHistogram

Histogram of lease renewal latency in microseconds.

revoke_latency: MetricHistogram

Histogram of lease revocation latency in microseconds.

teardown_latency: MetricHistogram

Histogram of teardown execution latency in microseconds.

auth_failures: MetricCounter

Total authentication failures (counter).

replay_rejections: MetricCounter

Total anti-replay cache rejections (counter).

token_validations: MetricCounter

Total capability token validations (counter).

token_failures: MetricCounter

Total capability token validation failures (counter).

stale_access_rejections: MetricCounter

Total stale access attempts after revoke/expiry (counter).

control_latency: MetricHistogram

Histogram of control-plane operation latencies in microseconds.

dataplane_latency: MetricHistogram

Histogram of dataplane operation latencies in microseconds.

tasklet_submit_latency: MetricHistogram

Histogram of tasklet submit (full dispatch) latencies in microseconds.

tasklet_exec_latency: MetricHistogram

Histogram of tasklet execution-only latencies in microseconds.

tasklet_submits: MetricCounter

Total tasklet submissions received (counter).

tasklet_completions: MetricCounter

Total tasklet executions that completed successfully (counter).

tasklet_failures: MetricCounter

Total tasklet executions that failed (counter).

tasklet_duration: MetricHistogram

Histogram of tasklet wall-clock duration in microseconds.

module_cache_hits: MetricCounter

Total module cache hits (counter).

module_cache_misses: MetricCounter

Total module cache misses (counter).

module_cache_stores: MetricCounter

Total module cache stores (counter).

module_cache_hash_mismatches: MetricCounter

Total module cache hash mismatches (counter).
