this page will contain information about UNKNOWN status issue
Present situation
Availability and Reliability calculations formulas:
Availability = Uptime / (Total time - Time_status_was_UNKNOWN) Reliability = Uptime / (Total time - Scheduled Downtime - Time_status_was_UNKNOWN)
How to read in context of UNKNOWN status:
- Period in which site is in status UNKNOWN is not taken into calculation.
- During this period EGI doesn’t know what is happening with the infrastructure.
Problems
- No policy for test developers when test should return UNKNOWN status. What does UNKNOWN status mean?
- Some of NGIs reach ~0% for all their sites and some reach even ~40%, sometimes disproporsions are even within one NGI. What/where is the reason for so high values and disproporsions?
