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 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 and suboptimal performance.
Feedback from the Designated Community is an important source of information about system behaviour and hardware performance. As described in 220.127.116.11.1, SP receives ongoing and extensive feedback from its Designated Community.
As a rule, SP replaces hardware within a 5-year period (i.e. every 5 years or less) even if the hardware is functioning normally. Typically, SP buys a 5-year warranty for hardware when available.
Systems administrators receive notices and alerts about stability and security issues from vendors on a regular basis.
