Step 1 - Check the environment readiness
If echo $TQL_HOME returns empty string then proceed to step number 2
Else run $ tql -engine -stop
Step 2 Set Environment Variables
Set JAVA_HOME & TQL_HOME. Look for TQL_HOME variable, it will be defined in ~/.bashrc or in ~/.bash_profile.
...
PATH=$PATH:$HOME/.local/bin:$HOME/bin:$TQL_HOME/bin:$JAVA_HOME/bin
Step 3 Create Installation Directory
Create Directory where you would want to install the software. For example: /home/ec2-user/ConfiguratorUI
Extract A-StackMonitoringDashboard zip into the created directory /home/ec2-user/ConfiguratorUI.
Step 4 Configure A-Stack Monitoring Dashboard to listen on HTTPS
Configure A-StackMonitoringDashboard to listen on HTTPS
Follows the step by step process defined in /home/ec2-user/ConfiguratorUI/StepsToCreateSSLCertificate.txt file.
Download all certificate (server.crt) files from all configurator nodes and import all certificates one by one using following command.
$ keytool -importcert -alias <alias_Name> -keystore "/opt/jdk1.8.0_131/jre/lib/security/cacerts" -storepass changeit -file server.crt
...
Copy server.crt file of A-StackConfigurator’s server into "/opt/jdk1.8.0_131/jre/lib/security/cacerts". This is for access daemon server from configuratorUI.
Step 5 Start the Monitoring Dashboard
Start tql engine by following command
$tql -engine -start
Step 6 Check Moniotring Dashboard Loads Properly
Check A-StackMonitoringDashboardis started successfully or not by hitting following URL in browser.
https://<ConfiguratorDeamon_IP_Address>:<Port>/
Following screen will be displayed in browser with no cluster.
Step 7 Cluster Setup
Now edit ClusterSetup.json file as per the guideline mentioned in Cluster Management. Put this file into /home/ec2-user/ConfiguratorUI.
Sample ClusterSetup.json file
Step 6 Start the Monitoring Dashboard
{ "ClusterSetup": { "ClusterId": "TestCluster_DemoDetails", "ShortName": "TestCluster_DemoDetails", "Description": "Test Cluster ", "InitialDirectory": "/home/ec2-user/testInstancesDetails1", "ExistingSetup": "false", "AppInstaller": { "InstallerBundleFile": "/home/ec2-user/deviceEngine.zip", "VersionNumber": "6.14" }, "Instances": { "InstanceDetails": [ { "InstanceName": "TestCluster_Shipra1", "HostName": "", "IPAddress": "18.216.140.179", "Port": "8087", "JvmArguments": "-Xms1027m -Xmx3g -XX:+HeapDumpOnOutOfMemoryError -XX:+PrintGCDetails -XX:+PrintGCDateStamps", "Path": "" }, { "InstanceName": "TestCluster_Muralee1", "HostName": "", "IPAddress": "18.216.140.179", "Port": "8089", "JvmArguments": "-Xms1027m -Xmx3g -XX:+HeapDumpOnOutOfMemoryError -XX:+PrintGCDetails -XX:+PrintGCDateStamps", "Path": "" } ] }, "LogFilesDirectory": "/home/ec2-user/testInstancesDetails/logs", } } |
All parameters must be configured as per A-SackConfiguratorDeamon and A-StackMonioringDashboard.
...
- Run following command to see list of clusters
$tql -cluster list - Execute below command to start particular cluster as mentioned in ClusterSetup.json file as 'ClusterId'.
$ tql -cluster -start clusterid=<cluster_id> - After starting cluster Dashboard will look as below.
- After selecting cluster, all cluster related information will be displayed on Dashboard.
