SP uses a variety of widely accepted, industry-standard techniques and tools to monitor the repository's hardware platform. Systems administrators at SP and the University of Toronto Libraries' Information Technology Services receive information about system behaviour and usage from a number of custom-built scripts, a Nagios systemmonitoring program, and monitoring tools functionality built into the hardware. These tools warn administrators about abnormal activity such as excessive processor loads and slow response times. In addition, staff monitor critical processes, such as ingest and data management, for malfunctions or suboptimal performance. System administrators receive notices and alerts from vendors on a regular basis.SP normally buys a 5-year warranty for hardware. and suboptimal performance.
