Data Access Performance - by Nodes

In the Data Access Performance - by Nodes dashboard, you can monitor for nodes in a VDC:

• TPS (success/failure)
• Bandwidth (read/write)
• Failed Requests/s by error type (user/system)
• Latency
• Successful Requests/s by Method
• Successful Requests/s by Node
• Successful Requests/s by Protocol
• Failed Requests/s by Method
• Failed Requests/s by Node
• Failed Requests/s by Protocol
• Failed Requests/s by error code
• Compare TPS of successful requests
• Compare TPS of failed requests
• Compare read bandwidth
• Compare write bandwidth
• Compare read latency
• Compare write latency

To view the Data Access Performance - by Nodes dashboard in the ECS Portal, select Advanced Monitoring > Related dashboards > Data Access Performance - by Nodes.

Data for all the nodes are visible in the default view. To select data for a node, click the legend parameter for the node below the graph.

Successful requests drill down shows the successful requests by method, node, and protocol.

Failures drill down shows the failed requests by method, node, protocol, and error code.

Compare: select multiple namespaces compares TPS of successful and failed requests, compare read/write bandwidth, compare read/write latency.
