Managing a Cluster

You can use the pgEdge Cloud console to review cluster information; highlight the name of a cluster in the Clusters menu to access the console for that cluster.

The console header displays information about the selected cluster:

• the console name
• the length of time since console creation
• the name of the cloud provider
• the number of regions that host nodes
• the instance type and size of each node

Also in the cluster header, a set of informational panes tell you the state of the cluster at a glance:

• the total node count
• the number of healthy nodes
• the number of unhealthy nodes
• the number of unresponsive nodes

The Cluster Information Tabs

The tabbed browser on the Cluster tab provides quick access to information about the state of your cluster:

• Select the Overview tab to view information about the cluster, and the databases currently deployed on the cluster. Detailed information about the cluster's nodes is displayed below. Click on an icon in the Database pane to navigate to detailed information about the selected database.
• Select the Metrics tab to view details about cluster resource use.
• Select the Logs tab to review cluster log files.

Accessing Cluster Details

Select the Overview tab to review information about the cluster. Panes on the Overview tab contain links to cluster artifacts:

• Select a database name in the Databases pane to navigate to the information page for that database.
• Select a backup store name in the Backup Store pane to navigate to the information page for the store.

The Nodes pane contains general node information. Use the tabbed browser to select a node to review information that node:

• Use the External IP Address when making ssh connections to the node.
• Use the Internal IP Address when configuring VPN connections to the node.
• The Instance Type and Volume Size fields provide node size information.
• The Instance ID identifies the node and associated resources in the cloud provider console.
• The UUID is a unique identifier for cluster resources outside of the cloud provider console.

Reviewing Cluster Metrics

Select from tabs across the top to review a graph containing:

• Metrics for All nodes in your cluster.
• Metrics for a specific node in your cluster.

Use the drop-down at the top of the Metrics pane allows you to specify the length of time displayed by each graph.

Select a point on a graph to display information about the graphed event that occurred on your cluster:

The graphs display metrics about:

Reviewing Cluster Log Files

Use the tabs across the top to select the node(s) for which you'd like to review the log files. When the Log Viewer opens:

• select System to review the system commands performed to manage your cluster.
• select Docker to review the Docker-specific commands executed to manage the container in which your cluster is running.
• select sshd to review details about ssh connections made to your cluster.

Use controls in the table header to sort or search the selected log file:

• Select a column heading to sort alphabetically by the column value; click a second time to reverse the sort order.
• Click the filter icon to the right of the Level heading to select a status from the drop-down; all rows assigned the selected status will be filtered to the top of the result set.

• Use the search box to the right of the Message label to enter a search string; the search term will be highlighted in the log file entries.

The Cluster Node Map

Below the cluster information tabs, a map displays the locations of the cluster's nodes. Hover over a mapped node to display the name and city in which the node resides.
