Collecting CGP Black Box Logs

Collecting CGP Black Box Logs

You can use the OMU to collect CGP black box logs. The log contents include the running status of the active and standby USM, CCF, ECS, MRP, and CloudMCU modules, and the fault information about the operating systems of the NEs. If you have used the VTS tool to collect fault information, skip this topic. You can use the OMU to collect CGP black box logs.

Principles

CGP black box logs include process black box logs and kernel black box logs.

  • Process black box logs record the running status of the active and standby modules of each NE. Collect these logs when a process is faulty or the CPU usage of a process is too high.
  • Kernel black box logs record the fault information of the OS. Collect these logs when the OS is down or restarts abnormally.

Procedure

  1. Log in to the HUAWEI Operation & Maintenance System.
  2. In the MML Command - CGP window, run GET SYSINFO to download the process or kernel black box log files of the corresponding module to the OMU VM.

    The NE ID and module ID are obtained based on alarm information. The following are example commands:

    • To download process black box log files, run the following command: GET SYSINFO: TYPE=BBOX, DEPLOYTYPE=VM, VMNAME="EC_USM_ALL_M";
    • To download kernel black box log files, run the following command: GET SYSINFO: TYPE=KBOX, DEPLOYTYPE=VM, VMNAME="EC_USM_ALL_M";

  3. Following the instructions provided in the following figure to open the directory where CGP black box log files are stored.

  4. Open the corresponding directory to download process or kernel black box log files.

    The cdp directory has sub-directories that are named after the associated VM. If processes on an active or standby VM stop unexpectedly, the downloaded black box logs are stored in two sub-directories in /Omulog/cdp and you only need to obtain the black box log files from the sub-directory that is named after VM hosting the stopped processes.

    • Process black box log files are named starting with BBOX, for example, BBOX_***.tar.gz.
    • Kernel black box log files are named starting with KBOX, for example, KBOX_***.tar.gz.
