Statistics for monitoring

Fields

channels_created: u64

channels_destroyed: u64

channels_expired: u64

channels_evicted: u64

operations_created: u64

operations_completed: u64

create_channel_requests: u64

create_channel_responses: u64

search_responses_resolved: u64

search_cache_entries: u64

search_retroactive_resolves: u64

client_messages: u64

PVA messages with is_server=false (sent by client)

server_messages: u64

PVA messages with is_server=true (sent by server)

memory_bytes: u64

Most recent value of PvaStateTracker::memory_estimate, refreshed by cleanup_expired so exporters need not re-walk the state.

operations_expired: u64

Operations aged out on their own last_seen, independently of any channel. This is what reclaims mid-stream placeholders.

shed_placeholder_ops: u64

Placeholder operations discarded to stay inside the memory ceiling.

shed_message_rings: u64

Debug message rings cleared to stay inside the memory ceiling.

shed_search_entries: u64

SEARCH cache entries discarded, by cap or by memory ceiling.

shed_channels: u64

Channels evicted specifically to stay inside the memory ceiling. These carried introspection, so this rising means coverage is being lost.
