Agent Metrics
Review per-agent CPU, memory, network, disk, and TCP metrics.
Agent Dashboard — CH Buffer Peak
Each time the copy engine records a copied or skipped object.
Agent Dashboard — Disk Read Latency
This is a host-wide measure of how long each individual read I/O is taking.
Agent Dashboard — Disk Write Latency
This is a host-wide measure of how long each individual write I/O is taking.
Agent Dashboard — Egress (Tx Mbps)
During an active copy job, Egress primarily reflects:
Agent Dashboard — Host CPU
This is host-wide CPU, not just the copy engine process.
Agent Dashboard — Ingress (Rx Mbps)
During an active copy job, Ingress primarily reflects:
Agent Dashboard — JVM CPU
Compare this against Host CPU to isolate how much of the host's compute budget the copy engine is consuming vs other processes.
Agent Dashboard — JVM Heap Used
The denominator is -Xmx (the JVM maximum heap).
TCP In-Use (Established)
This counts all active TCP connections on the host, including S3 connections, ClickHouse connections, console heartbeat connections.
Agent Dashboard — TCP Orphan
Orphaned sockets arise when a process closes a socket while data is still in-flight or when the remote end has not acknowledged a FIN.
