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 monitoring program, and monitoring tools 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 and suboptimal performance. System administrators receive notices and alerts from vendors on a regular basis.
Feedback from the Designated Community is an important source of information about system behaviour and hardware suitability. As described in 184.108.40.206.1, the repository receives ongoing and extensive feedback from its Designated Community.
SP normally buys a 5-year warranty for hardware. As a rule, SP replaces hardware within the warranty period (i.e. every 5 years or less) even if the hardware is functioning well.
