• The timestamps of most log messages is accurate only to the second. SSB can include more accurate timestamps: set how many digits should be included in the Timestamp fractions of a second field. This option corresponds to the frac_digits() parameter of syslog-ng.

  • If the server and SSB are located in a different timezone and you use the Legacy message template (which does not include timezone information), select the timezone of the server from the Timezone field.

  • Set the size of the disk buffer (in Megabytes) in the Output disk buffer field. If the remote server becomes unavailable, SSB will buffer messages to the hard disk, and continue sending the messages when the remote server becomes available. This option corresponds to the log_disk_fifo_size() parameter of syslog-ng.

    Note that SSB does not pre-allocate the hard disk required for the disk buffer, so make sure that the required disk space is available on SSB. For details on creating archiving policies and adjusting the disk-fillup prevention, see Archiving and cleanup and Preventing disk space fill up.

    The size of the disk buffer you need depends on the rate of the incoming messages, the size of the messages, and the length of the network outage that you want to cover. For example:

    • SSB is receiving 15000 messages per second

    • On the average, one message is 250 bytes long

    • You estimate that the longest time the destination will be unavailable is 4 hours

    In this case, you need a disk buffer for 250 [bytes] * 15000 [messages per second] * 4*60*60 [seconds] = 54000000000 [bytes], which is 54000 Megabytes (in other words, a bit over 50 GB).

  • To start sending messages to the destination, include the new destination in a logpath. For details, see Log paths: routing and processing messages.
