This will be one of the most anticipated admin and dev tools released for Sharepoint this year. It will come bundled with the updated version of the administrator toolkit for SharePoint 2010.
Ever had to trawl through multiple logs from multiple load balanced servers to figure out what really happened? Wished you could have your perfmon counters ready when analysing problems? The next version of the SPDiag tool will let you do that and much more. Run reports, save report snapshots, find events based on time, CorrelationID and... the login name! So Jo complains his page crashed and he did not make not of the correlation id? No problem. correlate all logs into one place on your desktop with minimal strain on the servers. Then run a search on his logon and the time window when it crashed and you'll have all the surrounding details, processes and counters available at your fingertips.
Also includes database stats, network stats and latency statistics to identify bottlenecks with some of you service app communications.
This tool was developed by the product team at Microsoft to assist them with the SharePoint development process. What's good for them can't be bad for us mere mortals!
Can't wait to get my hands on this gem. Supposedly coming out this month. Which really means sometime this year, probably during Q2 some time.
