Troubleshooting the dashboards
This topic covers the following issues that you may encounter when using the dashboard and provides more information to help solve the problem.
- I cannot access the dashboard.
- What time zone is shown in the dashboard?
- What is the session timeout value?
- My data isn't refreshing.
- Some content is unavailable due to permissions. is not running, but the dashboard is showing data.
- I do not see the fully qualified host name in the server information on the Home page.
- I do not see the version in the server or peer information on the Home or Peers page.
- Adapter information is missing on the Home page.
- Job information is missing on the Home page.
- The dashboard does not reflect the changes that I made in the gridmap.properties file.
- Users do not see Value reports in my dashboard and there are reports available
- I am trying to view Value reports for a daily time period, but no data is shown
- The list of available processes on the Create Report screen does not show all the available processes.
- Jobs are running on the Grid but data is not displayed on the Job View or Job List on the Health Dashboard
As a general practice, take the following steps to deal with data display issues:
- Refresh the data by clicking the refresh icon
. - Check with your Grid administrator to determine if there is an issue with
.
- Report the problem.
I cannot access the dashboard.
There are several possible reasons that you cannot access the dashboard. The following list provides some actions that might resolve the problem. If the problem persists, report it.
- Verify that the Tomcat server is running.
If it is not running, start the Tomcat server (see Configuring-your-environment-to-use-TrueSight-Orchestration-dashboards for instructions). - Verify that the healthdashboard.war file is located in the tomcat/webapps directory.
- Verify that the dashboard URL is accurate (see Accessing-the-dashboards). The default port is 18080. If you modified the port number, ensure that the port number is correct.
- Verify that cookies are enabled in the browser.
What time zone is shown in the dashboard?
The default time zone shown in the dashboard is the time zone of the host server.
What is the session timeout value?
The dashboard times out after 30 minutes of inactivity. You must log back into the dashboard.
My data isn't refreshing.
Click the refresh icon . If the data does not update, check with the Grid administrator to ensure that
is running and that there are no problems on that side.
is not running, but the dashboard is showing data.
If you logged into the dashboard before
stopped running, the last recorded data appears in the dashboard.
If you click the refresh icon only the authentication server information appears in the dashboard. If you log out of the dashboard, you will not be able to log back into the dashboard while
is not running.
I do not see the fully qualified host name in the server information on the Home page.
The dashboard does not report the fully qualified host names. As long as the first part of the name matches, there should not be a problem.
I do not see the version in the server or peer information on the Home or Peers page.
Verify that the server is running and that it is running
version 7.8 or later. Earlier versions are not supported.
Adapter information is missing on the Home page.
Click the refresh icon to ensure that the dashboard displays the latest data. If the adapter information is still missing, check with the Grid administrator to determine if there are any problems on the
side.
Job information is missing on the Home page.
If you believe that there are jobs running and you do not see them in the dashboard, first click the refresh icon to ensure that the dashboard displays the latest data. If the job information is still missing, ask the Grid administrator to confirm that the jobs are running and, if they are running, to determine if there is a problem on the
side.
The dashboard does not reflect the changes that I made in the gridmap.properties file.
Restart the Tomcat server and log back into the dashboard. Changes to the gridmap.properties file take effect after you restart the Tomcat server (see Configuring-your-environment-to-use-TrueSight-Orchestration-dashboards for instructions).
Users do not see Value reports in my dashboard and there are reports available
Ensure that users have Grid Management permission (see Assigning-grid-permissions for more information).
I am trying to view Value reports for a daily time period, but no data is shown
Check that there is data in the database tables (see Grid-performance-table-information). There should be data in the tables. If there is no data, check the following:
- Check that metrics collection is turned on (see Managing-grid-performance-records).
- Review your database configuration (see Configuring-the-metrics-and-audit-records-database) to be sure that it is configured correctly.
Ensure that your metrics collection settings work with your Value report settings. For example, if users will view Value reports using daily report periods, the grid metric Collection option should be set to minutes or hours. See Managing-grid-performance-records for information about metrics collection settings and see Value-Dashboard for details about viewing Value reports.
The list of available processes on the Create Report screen does not show all the available processes.
You may see an error in the dashboard.log file that is similar to the following.
org.apache.commons.dbcp.SQLNestedException: Cannot load JDBC driver class 'com.mysql.jdbc.Driver'
Complete the following steps:
- Verify that you have installed the JDBC driver in the AO_HOME/lib/add-ons directory for the dashboards. See Configuring-the-metrics-and-audit-records-database for instructions.
- Restart the dashboard server (see Starting-and-stopping-product-components-and-services).
- Execute each missing process through a schedule so that it creates a entry in the database and then click the refresh icon in the Create Report screen to update the process list. Adding-a-process-schedule for information.
Jobs are running on the Grid but data is not displayed on the Job View or Job List on the Health Dashboard
If the data for the latest jobs running on the Grid is not reflecting on the Job View or Job List on the Health Dashboard, you may want to verify if the Apache Cassandra database for the peer to which the dashboard is connected in running successfully.
If the Cassandra database is down, restart it manually. This issue occurs mostly on Windows 2008 R2 server.
To start the Cassandra database:
Go to command prompt and run the following command:
powershell Set-ExecutionPolicy Unrestricted
- Go to AO_HOME/cassandra/bin file.
- (Windows) Run the cassandra.bat file.
(Linux) Run the cassandra file.
Cassandra database is started.
If the job data is not displayed even after restarting the cassandra database, verify if the installation path as specified while installing the CDP contains any spaces. Run the following command to restart the cassandra database:
