Cluster observability

Instant Clusters include a built-in observability engine that streams cluster metrics at 5-second granularity directly to a Grafana dashboard. No configuration is required. Authentication is handled automatically when you launch a cluster.

Access the dashboard

In the left navigation, go to Resources → Clusters and select your cluster.
Click on a pod row in the cluster list. A side panel opens on the right.
In the side panel, select the Connect tab.
Under HTTP services, click Grafana (Port 8889).

Available metrics

Metrics are collected from two sources: NVIDIA DCGM for GPU telemetry and Node Exporter for host-level telemetry.

GPU metrics (DCGM)

Category	Metrics
Utilization	GPU core, memory copy, encoder, decoder utilization
Frame buffer	Used, free, total, reserved VRAM; used percentage; BAR1 used
Temperature	GPU temp, memory temp, slowdown threshold, shutdown threshold
Power	Usage, management limit, enforced limit, total energy consumption, power violation, thermal violation
Clocks	SM clock, memory clock, P-state, clock event reasons
PCIe	Link generation, link width, replay counter
ECC	Single-bit and double-bit aggregate errors, volatile double-bit errors
Row remapping	Correctable, uncorrectable, pending, failure
Fan	Fan speed

Host metrics (Node Exporter)

Category	Metrics
CPU / scheduling	CPU seconds by mode, frequency, load averages (1/5/15 min), running/blocked processes, forks, context switches, interrupts, scheduler run/wait time
Pressure (PSI)	CPU, I/O, and memory waiting and stalled seconds
Memory	Total, free, available, buffers, cached, swap, active/inactive pages, anonymous pages, huge pages, slab, kernel stack, page tables, dirty, writeback, committed memory, and more
vmstat	Page faults (minor/major), page in/out, swap in/out, OOM kills
Disk	Read/write bytes, completed reads/writes, merged ops, read/write time, I/O time, in-progress I/O, discards, flushes
Filesystem / FDs	Available, free, and total bytes; inode counts; file descriptor allocation
Network (device)	Receive/transmit bytes, packets, drops, errors, FIFO, frame, multicast, compressed; carrier changes, MTU, speed, queue length, interface info
Network (stack)	TCP open/established/segment/retransmit counters, UDP, ICMP, IP, socket stats, conntrack, ARP entries, softnet
InfiniBand / RoCE	Port state, physical state, rate
ethtool	Interface info, received counters
Thermal / power (host)	hwmon temperatures (current, min, crit), power average, thermal zone temp, cooling device state
EDAC (RAM ECC)	Correctable and uncorrectable memory errors per controller and CSROW
Time / clock	Current time, boot time, timezone offset, clocksource info, NTP error, frequency adjustment, TAI offset
XFS	Allocation, block-map, directory, inode, vnode, read/write operation counters
Entropy / misc	Available entropy bits, pool size, uname/OS/DMI/NVMe info, scrape metadata

The dashboards shown are a first pass. Coverage and layout will expand over time as new metrics and pre-built views are added.

What to look for

Signal	What it indicates
High VRAM pressure (`DCGM_FI_DEV_FB_USED_PERCENT`)	Model or batch size may be too large for GPU memory
Low GPU utilization (`DCGM_FI_DEV_GPU_UTIL`)	Data pipeline bottleneck, worker idle time, or checkpointing pauses
GPU temperature near slowdown threshold	Thermal throttling likely; check cooling and power limits
PCIe replay counter increasing	Hardware link issue — contact support
ECC double-bit errors	Uncorrectable GPU memory errors — contact support
NTP clock drift (`node_timex_estimated_error_seconds`)	Nodes out of sync; can affect distributed training coordination
High memory pressure (PSI stalled)	Host memory contention; consider reducing CPU-side batch pre-processing
Disk IOPS spikes	Dataset loading or checkpoint writes competing for I/O
