Configure compressed core dumps for NetScaler BLX

You can enable core dumps for NetScaler BLX using the core-dumps parameter in the blx.conf file.

The core dumps are generated according to the pattern in the core_pattern file on the Linux host:

/proc/sys/kernel/core_pattern

If no pattern is present in the core_pattern file, the following pattern is added to the file for core dumps:

/var/core/core-%e-sig%s-user%u-group%g-pid%p-time%t

Enable core dumps using the blx.conf file

You must use the Linux host CLI to enable the core dumps.

  1. Open the blx.conf file by running the following command:

    Note:

    You can use any text editor to edit the blx.conf file.

    nano /etc/blx/blx.conf
  2. Uncomment the core-dumps parameter and set it to 1, enable, or yes.

    blx-system-config { ... core-dumps: yes ... }
  3. Save the blx.conf file.

  4. Restart BLX.

    systemctl restart blx

After the BLX restarts, core dumps are enabled for BLX.

    Note:

    You can use any text editor to edit the blx.conf file.
