WEKA - CoreWeave Docs

The WEKA dashboard provides metrics for WEKA storage clusters. Use this dashboard to monitor cluster health and alerts, capacity, data protection status, IOPS, and per-filesystem performance. To view the dashboard, go to the WEKA dashboard.

For instructions about accessing CoreWeave Grafana dashboards, see Access and use CoreWeave Grafana dashboards.

The following sections describe each panel group on the dashboard.

Cluster-wide info

These panels summarize the overall state of the cluster, including alerts, capacity, throughput, and IOPS.

Panel	Description
Alerts Counter	Displays the total count of active alerts.
Failure domain	Displays information about the failure domain configuration or status.
Protection (Stripe width + Redundancy level)	Shows details about the data protection scheme, including stripe width and redundancy level.
Status	Shows the overall operational status.
Protection Status	Shows the current data protection status.
Protection Status Over Time	Shows data protection status.
Containers	Shows metrics related to running containers, such as their count or state.
Cluster Capacities	Displays the various capacity metrics of the cluster.
Processes	Displays metrics about running processes on the cluster Nodes.
Cluster drives	Displays information or status about the drives in the cluster.
Max Cpu Utilization	Tracks the maximum CPU utilization across the cluster.
Iops	Shows the total Input/Output Operations Per Second (IOPS) of the cluster.
Throughput	Shows the total data throughput of the cluster.
Drive Read/Write Requests/Sec	Shows the rate of read and write requests per second to the storage drives.
NIC Data rate per container type	Shows the Network Interface Card (NIC) data rate, categorized by the type of container.
AVG Drive Read/Write Latency	Shows the average latency for drive read and write operations.
Drive Read/Write Throughput	Shows the data throughput for drive read and write operations.

Per-filesystem info

These panels show read and write latency, request rates, and throughput broken down by filesystem.

Panel	Description
Average Read Latency by FS	Shows the average latency of read operations, broken down by individual filesystem (FS).
Average Write Latency by FS	Shows the average latency of write operations, broken down by individual filesystem (FS).
AVG Read Requests/Sec by FS	Shows the average number of read requests per second, with data grouped by filesystem (FS).
AVG Write Requests/Sec by FS	Shows the average number of write requests per second, with data grouped by filesystem (FS).
Read Throughput by FS	Shows the data read throughput, broken down by filesystem (FS).
Write Throughput by FS	Shows the data write throughput, broken down by filesystem (FS).

Top drives info

These panels surface drive health metrics, including S.M.A.R.T. errors, critical warnings, temperature, and failed or inactive drives.

Panel	Description
Drive Smart Media Errors	Shows the count of media-related errors (such as bad sectors) reported by the drive’s S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) system.
Drive Smart Critical Warnings	Shows any critical warnings issued by the drive’s S.M.A.R.T. system, which can be indicators of impending drive failure.
Drive Smart Composite Temp	Shows the composite temperature of the drives, a key health metric reported by S.M.A.R.T.
Failed / Inactive Drives	Shows any drives that are currently in a failed state or are otherwise inactive in the system.

Top processes info

These panels show per-process network traffic and drive request rates.

Panel	Description
Network Received	Displays the amount of incoming network traffic.
Network Transmitted	Displays the amount of outgoing network traffic.
Drive Read Requests	Displays the number or rate of read requests being made to the storage drives.
Drive Write Requests	Displays the number or rate of write requests being made to the storage drives.
