State and Availablity
State of the Monitor is not chanhing - Can this cause issue with the availablity report showing the service as down even though it was not . (We run SCOM 2007 R2) Does availablity report depend on State change events.. Is there any ways i can find the State Change events for a particulr agent ..I can se it in the console in health explorer but not all of them .. I believe some are missing. Any sql query to find this info.

Hi, The avability and SLA report is based on the avability monitor rollup, so they can affect the report. You can track state changes by a report. Note that alerts from rule dont change the state of a object, it will generate an alert, but there is no state change. Also, you can measure avability on only some objects from a computer, not the whole computer. That could also be the case where you see more state changes from a machine then what you see in the report.Anders Bengtsson | Microsoft PFE | blog at http://www.contoso.se

Hi Can you be more specific with examples but in general: 1) If monitors roll up to the object that you are running availability reports against then yes - the state of the object will be affected by the rollups. 2) The availability report reports the state of the object so it does rely on state change events to set the health correctly. For instance, if someone closes an alert but the health is still "unhealthy" then the report will show unhealthy (the closing of the underlying alert won't affect this). 3) If you can't see state changes for a particular object then it is usually the case that either: - there are no monitors that roll up to the object - there are no state changes recorded in the OperationsManager database. Check your database retention settings as it is probable that they have been purged from the OperationsManager database so are not visible any longer in the Operations Manager console.

Example: I generated monthly availablity report for one of the Web Application. It showed that it was 60% up and 40% down which was not what was true. As i drilled into the report for the the downtime i saw it showed as down between dates x and y (12 days) of the month. When i checked I could not find the state Change recorded in the Health Explorer. I know that the Web Application had no issue for 15 days. I told the reporting team that the issue is with the availblity report and which may be caused because the state of the Web Application did not chnage back from Critical to healthy automatically. How i came to know about this was another monitor. It is a Service Monitor. When I check the monthly availablity of that service i saw like 90% down Which was not true. I checked teh Health Explorer for it and I see that the Rollup - Availblity - Service Name (Entity) is showing Critical I clicked on the Plus sign and i see Two instances there : Service Running State - Name (Windows Service) --- This one is not checked and the icon has no check Service Running State - The One we had created --- Is green. Not sure whay Availablity showed Critical as under this all looks Green. I checke dthe state Change for That Critical Availablity and it shows only one event a month old .. for chnaging Green to Red I reset health , but it is not chnaging to green

Hi With regard to "I reset health , but it is not chnaging to green" - there are a couple of things to do that can kick this back to healthy: 1) Put the object that the monitor is targetted at into maintenance mode for, say, 15 minutes. When the object comes out of maintenance mode, health should be recalculated and reset to healthy. OR 2) Disable the monitor via an override - disable for this specific object (just remember where it is in the health explorer tree). Then once the monitor goes to an empty green circle, remove the override (to re-enable the monitor). This again should reset state. Targetting is key - do you have the Exchange 2010 Management Pack installed? This does target a monitor at the agent itself so issues with the MP can cause "agent" availability status to be misreported.

No we do not have the Exchange 2010 MP Installed. The steps you suggested (maintenance mode and overrides) would these ensure it wont happen in the future or - Is it just bug that Microsoft is working to resolve. Also Your service Monitoring guide that i read , in that you mentioned the reason whay we see two Service Running States One for (Windows Service) and other the One we created. So when i put this Service in the availablity report it shows both as we drill down: Service Running State - The One we had created Service Running State - Windows service But unfortunately for some of my services they show distinct uptime.. For 1 i rember it shows 100 Up time for : Service Running State - The One we had created But shows 80 % downtime for Service Running State - Windows service Anything i should do Thanks Again
