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
Use the drop-down menu in the upper-right corner to delete a cluster.
Use the lower section of the console window to access detailed information about each node.
The Cluster Overview Tabs
Tabs below the cluster header provide 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 theDatabase
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 the log files for the cluster.
The Nodes
pane displays node and connection details for each node in the cluster. To view information for a specific cluster node, select the tab labeled with the cluster name.
The Nodes
information pane contains general node information:
- 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
andVolume Size
fields provide node size information. - Use the
Instance ID
to identify the node and associated resources in the cloud provider console.
Below the Nodes
browser, 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.
The Metrics Tab
Select the Metrics
tab to display graphed metrics for the cluster. To display a graph that compares information for all of the nodes in the cluster, choose the All Nodes
display option. To graph information for a single cluster node, choose the cluster name/location combination in the tab browser.
The graphs display usage statistics for each node in the cluster:
- The
CPU
graph displays the percentage of CPU usage. - The
Memory Usage
graph displays the percentage of Memory usage. - The
Disk Usage
graph displays the amount of disk used(in GB). - The
Running Processes
graph displays a count of the number of processes used. - The
Network Receive
graph displays the time used by inbound processes (in Kb). - The
Network Send
graph displays the time used by outbound processes (in Kb).
Each node in the cluster is represented by a different color of line in the graph. Use the Select Timeframe
drop-down to select the amount of time that is represented in the Metrics
graphs.
Position the selection bar to display detailed metrics for a specific point in time.
The Logs Tab
Select the Logs
tab to display logging activity for the cluster. To display the log files for all of the nodes in the cluster, choose the All Nodes
display option. To display the log files for a single specific cluster node, choose the node name/location combination in the tab browser.
Navigation buttons across the top of the log display allow quick access to log files:
-
The
system
log displays system calls used to create and manage the nodes on your system. -
The
nodectl
log displays the pgEdge management commands invoked while creating and managing the cluster. For detailed information about pgEdge commands, see the documentation for pgEdge Platform. -
The
postgres
log displays user commands invoked against the PostgreSQL server (opens in a new tab) that resides on the node. -
The
docker
log displays the commands that manage the Docker containers used by your deployment. -
The
sshd
log displays the log files for the SSH daemon monitoring your nodes for connections.
