Description

This article describes a possible workaround if users are unable to load the Network Monitoring Dashboard, Topology, and Database report page and encounter the "error 404, page not found" error.

Solution

You can run the Fix Karaf script to delete cached items. This script tries to fix configuration problems by pruning /opt/opennms/data and restoring all Karaf-related configuration files to a pristine state.

  1. service jmp-opennms stop
  2. /opt/opennms/bin/fix-karaf-setup.sh >> (Note: Use the path to access the script from the server.)
  3. service jmp-opennms start

CAUTION

The Fix Karaf script can be destructive to files that may contain user-specific configuration settings. We recommend that you back up /opt/opennms/etc before running the script.
