Editing Configuration General Settings

You can modify the default configuration at any time.

Procedure

  1. Open the LogLogic® Universal Collector Console by clicking on the shortcut.
  2. Click .
  3. Modify the following information:
    Option Description
    Name Name of the configuration.
    Communication Port Port used by LogLogic® Universal Collector to get information (for example, status, metrics, memory used...) by using the CLI. Make sure this port is not already used. Otherwise LogLogic® Universal Collector will not work.
    Collector Domain

    Using the Collector Domain feature, users can provide custom identification for different domains throughout their environment, when used in conjunction with LogLogic® Universal Collector. Having this capability allows for unique identification of distinct log sources that use duplicate IP addresses across multiple domains within the same organization.

    TCP/UDP socket buffer size Defines the TCP/UDP socket buffer size in KB. Configure the buffer as per the data processing capacity. If the data processing is slower than the data received, it can result in data loss when the buffer is full.
    UDP max packet size Defines the maximum UDP packet size in KB. Configure this field based on the amount of data collected from the UDP collector. The maximum size is 64 KB.

    Notes for Red Hat and SUSE Linux Enterprise

    If you obtain a log message saying “Syslog Unable to set the required socket buffer size”, then it is a good practice to increase the maximum size of the buffer on your RHEL or SUSE system.

    On RHEL or SUSE system, the default maximum TCP/UDP buffer size is 128 KB.

    In the LogLogic® Universal Collector configuration file, the default value of the socket buffer size is 1MB. These parameters apply to all the Syslog collectors configured in LogLogic® Universal Collector. Therefore, you must increase the maximum value of the Syslog buffer already set with a specific command.

    To change the maximum value of the buffer:

    1. Log in as root on the system.
    2. Enter the following command (example with 1 Megabyte):

      sysctl -w net.core.rmem_max=1048576 (this value is expressed in bytes)

    Note: The modification of the system parameter will impact the maximum limitations for all sockets.
  4. Click Apply.
    The configuration is updated.
