Patch reliability is unclear, but widespread attacks make patching prudent. Go ahead and patch, but watch out for potential problems. |
Hi all – hope all are keeping safe during this virus time – take care.
Attached my excel sheet – its for an IT organisation, measuring “Availability”.
Reference: https://www.fiixsoftware.com/how-do-maintainability-and-reliability-affect-availability/
Attached is my try on this. Please can you help me put this together? Thank you in advance for your help with it.
Column E: Minutes downtime per month
Column F: Not sure how to show this as a percentage?
Thank you.
Hi
Well, assuming that each Application runs constantly for the entire 30 day period except for the recorded downtime, then the Uptime minutes is simply
(uptime minutes) = (minutes in the month) – (downtime minutes)
So the uptime% is then simply (uptime minutes)/(minutes in the month) expressed as %
..and (downtime%) = (downtime minutes)/(minutes in the month) expressed as %
..see attached
