Hi again, I have been trying to figure out SLA's for some hours now and start to understand them.
I noticed in the SLA Report overview of some of my Storage Interfaces (which were 'failing the SLA') that there are lots of events, a selection: Start Stop Duration Type 2005-01-21 00:00:02 2005-01-21 00:30:32 00:30:30 hs SLA X 2005-01-21 00:30:02 2005-01-21 01:00:32 00:30:30 hs SLA X 2005-01-21 01:00:02 2005-01-21 01:30:32 00:30:30 hs SLA X For some reason they overlap, I guess there is a reason for that. But now one sees multiple SLA 'failures', while it is simply a large one. This also results in a longer Unavailable time than view range and a negative Availability percentage. This was for a harddrive, but my Linux Memory is using Storage polling too, and that is more dynamic. Because of all these overlapping events, you don't see when the % storage is not too high. About the Reports event view. I noticed that events that are partially outside the selected time range are not listed in the overview (ie start time inside the range, end time outside the range). I could imagine adding an event with a start date, but no end date to that list. Now you end an event after 30:30 minutes, but if that is changed, an event might not show up while it started before the selected time period and is still going on. I'll try to look into the code showing those reports myself now.. I have been trying to see whether one can define an SLA that isn't based on current values, but takes the duration of 'failures' into account. Ie, give an SLA Report event if a TCP Content Check has failed for over 30 minutes. But all current SLA's are not time dependant. Such a feature would mean a second level of SLA's. Because you could write an SLA trigger that fires when another SLA (CPU > 80%) has been failing for, say, 10 minutes. Just some notices. The 0.8.0pre layout is a real improvement, though it requires some getting used to. ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program. ------------------------------------------------------- This SF.Net email is sponsored by: IntelliVIEW -- Interactive Reporting Tool for open source databases.
