Downloading diagnostic data 

Download diagnostics information about the OpsCenter daemon and all the nodes in a specific cluster. Attach the diagnostic data to support tickets to facilitate resolving any issues.

Download a compressed tarball that contains diagnostic information about the OpsCenter daemon and all the nodes in a specific cluster. Examine the diagnostic data and provide the diagnostic tarball to DataStax Support to facilitate resolving any issues.
Note: If downloading the tarball times out, increase the default value of the diagnostic_tarball_download_timeout option in cluster_name.conf. Increasing the default value is recommended for DSE multi-instance clusters or for slower machines and connections.

cluster_name.conf 

The location of the cluster_name.conf file depends on the type of installation:

  • Package installations: /etc/opscenter/clusters/cluster_name.conf
  • Tarball installations: install_location/conf/clusters/cluster_name.conf

Procedure

  1. Click Help > Diagnostics.
    The Collect Diagnostic Data dialog appears.

  2. Click Download.
  3. If DataStax Enterprise was installed via the Installer-No Services or tarball or the system.log is not located in the default directory, OpsCenter cannot detect its location and prompts you to enter the full path to the system.log location. Enter the full path to the DataStax Enterprise system log in the System Log Location box and click Save.



    Note: If you do not enter the system log location, the system log information is not included in the diagnostic report tarball.
  4. A message indicates OpsCenter is collecting cluster data. Save the tarball to your local machine.
    diagnostics.tar.gz
    Depending on your browser settings, you might be prompted for a file directory to save the tarball in. For assistance with troubleshooting issues, provide the diagnostic tarball to DataStax Support.
