Issue: The alert dashboard and the charts in the alert view do not refresh or display new alerts. However, the table in the alert view displays the newly generated alerts. This issue could happen because of a corrupt alert index.
Fix: Re-index all the alerts as follows:
Stop the Sentinel server.
rcsentinel stop
Change to the following directory:
/opt/novell/sentinel/3rdparty/mongoconnector
Remove the config.txt file.
rm config.txt
Start the Sentinel server.
rcsentinel start
The alert index is rebuilt. The alert dashboard and the charts in the alert view display all the alerts.
