Products documentation

After the installation or upgrade, you can't reach the UI via your browser.

• Check java is installed: # java –version must return java version and show a 64-Bit Server edition
• Make sure the version is compatible with prerequisites

• In your browser address bar, enter a valid url, including protocol (i.e. : http://localhost:8888/)
  • Make sure to use the correct HTTP or HTTPS scheme according to the port number.
  • Look in bin/setenv.sh file to see the configured HTTP and HTTPS ports

• Check the application port: Using nestat or equivalent, check that the configured application port are listening, or not used by another program:
• In below example, the result shows that the server is listing on port 8443 for any external connections: 0.0.0.0:8443

[root@server]# netstat -tnlaput

• To quickly identify if the firewall is causing probems:
  • Try connecting on the Redpeaks port from a different server: # telnet promonitor-server 8443 the connection must open
  • If not opening, try disabling the firewall: # systemctl stop firewalld
  • Try again to external connection. If it works, then the firewall is blocking and you need to add a rule to allow incoming traffic to Redpeaks

• Check if the Redpeaks service is installed and running: # systemctl status promonitor

Service is not running:

• If the service is stopped, start it with # systemctl start promonitor
• Then look in the logs/server.log file if the service is starting correctly.
• Check that service status stays

Service is running with error status:

When the service is running with errors, it is often because of failed or incomplete upgrade process. You can recover with the following:

• Stop the service: # systemctl stop promonitor
• Check that no promonitor processes are still running: # ps -eaf | grep -i promoni
• Kill remaining process if any
• Go to webapps folder and check that ROOT.war file exists
• Remove ROOT folder (Do not remove ROOT.war file)
• Restart the service: # systemctl start promonitor
• Check logs/server.log file

Service is running with error status or having DB errors

In case you can't reach the application and logs are showing DB errors:

• First, try to redeploy the application as above
• If still failing, you can try to restart with a fresh DB
  • Stop the service: # systemctl stop promonitor
  • Rename db folder
  • Restart the service: # systemctl start promonitor
  • Test the application and try to log in.
  • Load the latest snapshot to set your configuration back in place.
  • Note: The snapshot doesn't contain any application/historical metadata and those will be lost.
