How is it measured
  • You should record weekly the disk space available on the server plotting on a graph the free disk space against the maximum capacity of the disks. Record any reasons for major changes noted (for example, new disks added or loading of extra applications) and input the graph to the Service Level Management process for reporting.  You could use or adapt the disk usage report provided or look at an example disk usage report to get an idea of the information you can collect.

  • The log can be used to identify trends and action taken before lack of disk space starts to affect network performance. The first action is to try and reduce the amount of disk space used by:
  • running disk-cleaning utilities to clear out temporary files (temporary web browser files can be a particularly large consumer of disk space)
  • removing unnecessary or infrequently used software applications
  • deleting or moving personal data that has been inappropriately stored on the server.
  • The above actions need to be carried out each time disk space is running low but eventually you will probably need to consider:
  • installing extra disks
  • replacing smaller disks with larger units
  • installing a separate disk array to store large volumes of data.


  • The person responsible for technical support in the school along with the school leadership team should conduct an annual review of the suitability and cost effectiveness of the network monitoring software. The weekly reports of network performance and the output from the Problem Management process should be inputs to this review.
If the right network monitoring software has been chosen and appropriately configured, and the management tasks have been rigorously followed, then it should be possible to detect a measurable improvement in network performance. If this is not the case, the review should determine whether the correct solution has been chosen or whether the set- up or day-to-day management of the software could be improved.
