Management is on my back again. Now they want me to provide them with a measure of Sharepoint 's availability for reporting purposes. Given the system is architected for high availability makes this a little difficult to determine compared with many other systems.
Downtime for some of our other systems is merely determined by the state of the server. But it's not so cut and dry for a SharePoint farm. For example just because one load balanced WFE server is down does not mean the system is unavailable. Also part of SharePoint (a web application, site collection) might be down but not another.
Just wondering how others have gone about reporting availability. Does anyone have a clever and concise definition that they use to measure availability that covers Sharepoint's unique nature. Something simple that management can understand. Also does anyone use a good tool that measures availability. Just pinging farm servers just doesn't cut it.
