This was bth a challenging experience as the University culd nt affrd dwntime fr its cmputer labs and staff desktps. It was required f me t implement a slutin which had an easy migratin path frm the ld system t the new. Implemented a netwrk and systems management mnitring system. The system was designed as an interim systems mnitring slutin. The university restructured its ICT infrastructure t cater fr the implementatin f a new netwrk. Nagis and Cacti was able t assist until it was replaced by a mre rbust prprietary slutin. I was tasked t implement. The system was used t respnd practively and fr service level agreement reprts.
