Biggest take-away: everyone who runs Microsoft web apps wanted a tool like LeanSentry.
IT operation engineers, administrators, and developers all felt the pain of production troubleshooting, and wanted something that can help them diagnose production problems faster.
We spoke to hundreds of people, and asked almost everyone whether they've ever had to troubleshot a website hang or crash in production. Most of the time, the answer was "yes".
We then asked, did you enjoy it? 100% of the time, the answer was "Hell no"! People told us dozens of stories of trying to catch a hang in production, and how long it took to figure out the root cause, even when Microsoft support was involved.
Then we got to hear the classic story of finger-pointing between the IT administrator that runs the production environment, and the developers that build the application. Often, the operations team didn't have enough evidence to convince the developer that the issue was in their code ... And the developer didn't have enough information from production to reproduce the issue in the test environment.
We then showed LeanSentry's automatic IIS/ASPNET hang diagnostics, which automatically detects hangs and instantly identifies their root cause, including blocking IIS modules, CLR threadpool exhaustion, or application code. People loved it!
The feedback we got was pretty consistent. Everyone's favorite things were:
1. Automatically diagnosing IIS and ASP.NET problems in production. Many people couldn't believe that we do this at first. Many times we had to explain our Windows Server background and that Microsoft web platform development is all we do. Of course, seeing the hang diagnostic demo also helped.
2. Lightweight monitoring without profilers. IT administrators really appreciated the fact that LeanSentry uses lightweight Windows protocols like Performance counters and IIS logs to monitor the server, instead of loading application profilers. Many said "we dont want the performance monitoring tool to become the performance problem", as we often hear from users of profiler based tools.
Many also loved how LeanSentry can be sandboxed to a separate VM, and monitor the production servers without installing anything on them. No reboots, iisresets, etc.
3. Making everything simpler. IT managers that handled web operations loved how simple the LeanSentry dashboard was, and how it was very easy to see all the requests, errors, and performance data in one place. Developers also loved aggregating the errors across Windows Server, IIS, and ASP.NET and getting all the details needed to troubleshoot the error. We heard a lot of complaints about how complicated SCOM was, and how LeanSentry dashboard was the "anti-SCOM". The consensus was that LeanSentry complements environments that use SCOM, by providing a much simpler view to track problems and get the details to resolve them.
4. Working directly with the developer team. People loved talking directly with the founders and the developer team. Many were used to dealing with company sales people at the other booths. We loved showing everyone the Olark chat box on our site, where you can talk directly to the dev team anytime.
The top questions people asked were:
1. How do you diagnose hangs in a lightweight way? We explained our multi-stage process for diagnosing hangs that insures lightweight monitoring, and still provides debug-level resolution for hangs. We use similar approaches for diagnosing other problems, where we first detect many potential symptoms of a problem using lightweight monitoring like performance counters, and only perform the intensive diagnostic once we know the problem already exists.
2. How is LeanSentry different from SCOM/AviCode/New Relic? In many ways! We put together a page to explain what makes LeanSentry different.
3. Can I host LeanSentry in my environment? You can't just yet, but you will be able to later this year! We now have a beta program for people who want to help us do this. Email us for more info!
