  19. ROI • SLA monitoring for: • Customer circuits • Server systems • Reporting for circuits / leased lines per customer request • Proactive bandwidth control (Health Reports) • eHealth reports gives the answer to the statement: • “I can’t work – there must be a problem with the network.” • “The fault is not the network.” • “The fault is not the server.” Dipl.-Inf.
