Author here, this is using free Microsoft tools only. Was a big hit in our troubleshooting course, so we figured we release it for public benefit.

Hey DennisM, The first thing I would check is that you can hit the webserver. You can do some of that with a tool like PortCheck: http://mvolo.com/check-iis-network-connectivity-with-portche... . Best, Mike

We share your sentiment! We are a large-scale startup built entirely on the MSFT stack, in Azure cloud, for the MSFT platform. People on HN don't often talk about it, but it does happen, and apparently quite a bit judging by our users :)

hey bigdubs, That's certainly a good one! One of the things we'll do to help resolve the hang is to identify where blocking is happening. This will pinpoint the session state module in AcquireRequestState as the culprit. Although, I also ha

Racism and racially-motivated policies (mostly affirmative action) definitely exist in the US ... Particularly for older, and less educated populations. But the bottom line is, even if not everyone likes you in the US, you can still live a

hi there, The post is about selecting a top level metric for monitoring website performance. One a problem is indicated, you would definitely need to drill in to figure out what part of your app is affected, when, and what caused it. LeanS

hi nateabele, Author here. Did you also search for stdev, st.dev, variance? Just kidding. The post is not about averages. Its about selecting the right metric to track website performance. Standard deviation would surely qualify the avg. l

hi, author here. Unfortunately, you HAVE TO do it. If you do not set a threshold for what is acceptable, how do you determine whether or not your are providing an acceptable experience to your users? No amount of aggregate metrics can help

hi Steve, Author here. I think most people on HN would echo your sentinment about averages wholesale ... But I wanted to go a little deeper into selecting a better alternative for operational monitoring. Its easy to say "averages are bad"

Hi edouard, I completely agree! Keeping toplevel metrics SIMPLE is the key. Of course, simple but also not misleading you into any wrong beliefs. While we liked the 95 percentile approach, we decided against it. Its still too focused on th

hi Jabbles, Author here. The 99 or 95 percentile is a much better metric! We also make the case for the industry standard Apdex or our derived metric, sat score. These are becoming more and more in use by APM tools like us or New Reli

Hi, author here. I am in complete agreement. Unfortunately, a lot of monitoring and APM tools still lead with average response time as one of the toplevel metrics. And a lot of people still make incorrect assumptions based on it. Although

Hi, founder here. 1. You are absolutely right, the agent is an optional component. Without the agent, you get most of LeanSentry's monitoring features without having to install ANYTHING on your production servers. 2. We know the name of th

hi jolt, I hear your sentiment re: hosting LeanSentry yourself. We actually started this way, but over time realized that in order to support our data processing and analysis needs, we needed to host this in our own data center. The major

Hi meaty, You are right, most APM tools are working on covering multiple platforms. We are trying to provide extra depth into the Windows Server platform because thats what we know (for example, I used to be the PM for IIS 7 / ASP.NET). Our

Hi mijustin, founder here. LeanSentry is somewhat similar to New Relic in that we provide server and application performance monitoring. However, we are 100% focused on the Windows Server/IIS/ASP.NET stack (that's our background), and as a
