Live Metrics - Nodes

Overview

Node Live Metrics displays a searchable and filterable list of the Nodes on the Kubernetes cluster. The table displays:

  • Status: The current status of the Node
  • Name: The name of the Node
  • Load Average: The load average on the Node
  • Memory/CPU: A mini graph that displays a snapshot of the current memory/CPU usage
  • Memory/CPU Usage: A numerical readout of the current memory/CPU usage in gigabytes/CPU cores
  • Memory/CPU Request: A numerical readout of the current memory/CPU request in gigabytes/CPU cores
  • Memory/CPU Limit: A numerical readout of the current memory/CPU limit in gigabytes/CPU cores

Node Details

Node Data

Clicking on the name of the Node will bring you to the Node Data details page. If you are using a Virtual Machine, the data displayed is relevant to the Virtual Machine image. This page displays the following:

  • Name: Name of the Node
  • Available Memory: Total memory on the Node
  • Namespaces: Total Namespaces on the Node
  • Status: Status of the Node
  • OS: Operating system deployed on the Node
  • Available Cores: Total CPU/vCPU cores on the Node
  • Pods: Number of Pods and their status on the Node
  • Storage: Total free memory on the Node / total memory on the Node
  • IP: IP address of the Node
  • Role: Kubernetes role for the Node (Master/Worker)
  • Container Runtime: Container runtime utilized by Kubernetes
  • K8s Version: Kubernetes version
  • SDN: Lowest latency for the network on the Node / highest latency for the network on the Node
  • DNS: Current latency for the DNS service on the Node

The recent events section displays Sosivio AI generated events for the Node.

Real-Time Metrics

  • Real Time Metrics displays a live view of metrics for the Node.
  • Above the graph you can select the following information to view:
    • Memory: Metrics around the Nodes usage of RAM in gigabytes
    • CPU: Metrics around the Nodes usage of CPU/vCPU cores in core counts

On the bottom on the graph you can adjust the slider to adjust the length of time for the displayed information. Slide it to the left to view more data from time before what is currently displayed and to the right to display more information after the information that is currently displayed. You can also drag the slide to the left of right to adjust the information from the times being displayed.

Below the slider display you can select or de-select the following from the Nodes to either display or hide the information:

  • Request: The resource request for the Nodes
  • Limit: The resource limit for the Nodes
  • Average: The average usage for the Nodes for the past 24 hours, or length of the Nodes existence if less than 24 hours
  • Maximum: The maximum usage for the Nodes for the past 24 hours, or length of the Nodes existence if less than 24 hours

Network Connections

Network Connections displays the Nodes network connections for the following:

  • Listen: Represents waiting for a connection request from any remote TCP and port
  • SYN-Sent: Represents waiting for a matching connection request after having sent a connection request
  • SYN-Received: Represents waiting for a confirming connection request acknowledgment after having both received and sent a connection request
  • Established: Represents an open connection, data received can be delivered to the user. The normal state for the data transfer phase of the connection
  • FIN-Wait-1: Represents waiting for a connection termination request from the remote TCP, or an acknowledgment of the connection termination request previously sent
  • FIN-Wait-2: Represents waiting for a connection termination request from the remote TCP
  • Close-Wait: Represents waiting for a connection termination request from the local user
  • Closing: Represents waiting for a connection termination request acknowledgment from the remote TCP
  • Last-ACK: Represents waiting for an acknowledgment of the connection termination request previously sent to the remote TCP (which includes an acknowledgment of its connection termination request)
  • Time-Wait: Represents waiting for enough time to pass to be sure the remote TCP received the acknowledgment of its connection termination request
  • Closed: Represents no connection state at all

You can hover over each connection status to see a description. You can filter by Status or Amount. The Pie Chart represents the ratio between different types of connections. Click on a sector or on a label below the chart to see a description of each connection type.
