How do I create a debug dump on Blue Coat Director?

How do I upload the Director debug dump to Blue Coat for analysis?


Complete the following tasks to generate and send the debug dump file on Blue Coat Director

Task 1 - Generate a debug dump file

To generate a debug dump file: 

  1. Log in to the CLI and enter enable mode.
  2. Check the local logging level (the default is notice): 
     #show logging
  3. Set the local logging level to debug:
    #config t 
    logging local debug
  4. Reproduce the issue that you are troubleshooting.
  5. Generate the debug dump file:
    (config)#debug dump generate
    You will see the dump file successfully generated as example output below:

    Generating debugging dump... 
    Dump file successfully written to ciqinfo-Director-20xx.xx.xx-xxx.tgz
  6. Set the local logging back to its previous setting:
    (config)#logging local <level>
    For example, if the previous setting was notice, enter #(config)logging local notice.

Note: For steps on creating archives or retrieving an overlap file, refer to KB1441.

Task 2: Upload the debug dump file

To upload the debug dump file, use Method 1 below. Use Method 2 only if Method 1 fails.

Method 1: (Preferred method) Upload the dump file to a local FTP server 

  1. In the CLI, view the debug dump logs:
    (config)#show debug dumps
  2. Take note of the name of the dump file you created in Task 1.
  3. Upload the dump file to an FTP server:
    (config)#debug dump upload <name of dump file> ftp://<FTP_Server>/<name of dump file> username <username> password <password>
    where <FTP_Server> is the IP address or DNS name of the FTP server.

Method 2: (Use only if Method 1 fails) Upload the dump file manually via shell command

Note: Do not use this method unless Method 1 fails. 

  1. In the CLI, go into shell and upload the dump file manually. Enter the following CLI commands:
    (config)# shell
    Releasing the configuration lock.
    # cd /local/userfiles
    # ls
    cIQconfig_050202     dump?ciqinfo-Director-20xx.xx.xx-xxx.tgz
    # mv dump?ciqinfo-Director-20xx.xx.xx-xxx.tgz Debug_dump.tgz
    # ftp
