# VAST Actors

> Grafana dashboard for monitoring VAST Actor instance NFS bandwidth, IOPS, and read/write statistics

To view the dashboard, go to the [VAST Actors dashboard](https://cks-grafana.coreweave.com/d/ddq5gg6gi5lvke/vast-actors).

<Info>
  For instructions about accessing CoreWeave Grafana dashboards, see [Access and use CoreWeave Grafana dashboards](/observability/managed-grafana/access).

The VAST Actors dashboard provides metrics related to VAST Actor instances. It contains the following panels:

| Panel                                  | Description                                                                     |
| -------------------------------------- | ------------------------------------------------------------------------------- |
| **NFS Bandwidth**                      | Shows overall network bandwidth usage for the NFS service.                      |
| **NFS Requests per Second**            | Shows the rate of NFS requests processed each second.                           |
| **Metadata IOPS Response Time**        | Shows the response time for metadata Input/Output Operations Per Second (IOPS). |
| **Nodes with High RPC Response Times** | Shows Nodes experiencing high response times for Remote Procedure Calls (RPC).  |
| **Vast Write Bandwidth per User**      | Shows write bandwidth by user.                                                  |
| **Vast Write IOPS per User**           | Shows write IOPS by user.                                                       |
| **Vast Read Bandwidth per User**       | Shows read bandwidth by user.                                                   |
| **Vast Read IOPS per User**            | Shows read IOPS by user.                                                        |
| **Replication Bandwidth**              | Shows replication bandwidth.                                                    |
| **Replication IOPS**                   | Shows replication IOPS.                                                         |
