Members

In the VMware GemFire® Management Console™, the Members tab displays additional details about the running locators and servers of the connected cluster.

GemFire Version

The current version of the connected cluster. For clusters running on the Tanzu Application Service or Kubernetes, this column shows the underlying version of GemFire running. For example, if a cluster is connected and is using VMware GemFire for Tanzu Application Service version 1.14.6, this column will show GemFire version 9.15.3.

Cluster Connection

Users can copy this connection string into a GemFire Shell (gfsh), if needed, to connect to the cluster. The connection string does not include any username, password, or authentication token information. If required by gfsh, these must be provided by the user.

Locators and Servers Tables

The lower section of the user interface displays information about all of the locators and servers currently running in the connected cluster.

The release of GemFire version 10.1 introduced additional status and information for cluster members.

This enhanced member status and information is available within the GemFire Management Console for clusters leveraging GemFire v10.1 and connected to the console.

For more information about this additional status and information, see Operational Status Improvements in the VMware GemFire 10.1 Release Notes.

GemFire v10.1 and higher

Locators and Servers

The number next to the Locators and Servers labels indicates the total number of that member type that are running.

The tables in this section provide additional details about each member:

  • Name: The name of the member.

  • Status: The current status of the member. The status will be one of the following:

    • Initializing: The member is starting.

    • Ready: The member has started successfully and is ready to connect to clients.

  • Host: The IP address of the host where the member is running.

  • Port: The port number of the member.

  • Heap Utilization: The current percentage of heap space used by the member.

  • Load Average 1: The average number of threads on the host machine that are in the run queue or are waiting for disk I/O over the last minute. The load is proportional to the number of processor cores in use. For example, “100% utilization” corresponds to a load average of 1.0 on a single-core system. For more information, see list members in the gfsh Command Help section of the GemFire product documentation.

  • Redundancy Zone: The name of the redundancy zone, if the member has been assigned to a redundancy zone.

  • Up Time: The amount of time the member has been running without stopping, restarting, or being shut down.

By clicking on the expansion arrow next to a member row, users can see comprehensive details about that specific member.

This detailed information is categorized into three primary sections:

  • Member Details: This section provides basic details of the member, including data such as its ID, Prometheus metrics URL (if enabled), operational time zone, log file path, and more.

  • Status Overview: Here, users find a summary of the member’s status, including details such as locators, existing regions (for servers only), member-specific alerts, initial and maximum heap sizes, among others.

  • Current Configuration: In this section, users can explore and download the current configuration settings for the member, enabling users to delve deeper into the GemFire cluster’s setup and parameters.

GemFire v9.15.x and 10.0.x

Locators

This table displays all of the locators currently running in the connected cluster.

The number next to the Locators label indicates the total number of running locators.

The table in this section provides additional details about each locator:

  • Name: The name of the locator.
  • Host: The IP address of the host where the locator is running.
  • Heap Usage: The amount of the JVM heap being used by the locator.
  • CPU Utilization: The percentage of the CPU being used by the locator.
  • Up Time: The amount of time the locator has been running without stopping, restarting, or being shut down.

Servers

This table displays all of the servers currently running in the connected cluster.

The number next to the Servers label indicates the total number of running servers.

The table in this section provides additional details about each server:

  • Name: The name of the server.
  • Host: The IP address of the host where the server is running.
  • Port: The port used to connect to the server.
  • Heap Usage: The amount of the JVM heap being used by the server.
  • CPU Utilization: The percentage of the CPU being used by the server.
  • Up Time: The amount of time the server has been running without stopping, restarting, or being shut down.
