| By default, the statistics are presented to Xymon using a so-called 'trends' data-message. These type of messages do not carry a status nor a time stamp. Thus problems in collecting the statistics cannot be passed as a status. The independent polling cycles at client and server introduce variable delays, which cannot be accounted for, although the time of data collection is known at the server-side script. | By default, the statistics are presented to Xymon using a so-called 'trends' data-message.

| | It is assumed that the BIND statistics file contains only one set of statistics. Thus the new statistics overwrite the old statistics, rather than being appended. |

| This script is only tested using 'trends'-messages. The function to use a status message to inform Xymon has thus not been tested. | This script is only tested using 'trends'-messages. The function to use a status message to inform Xymon has thus not been tested. |
