OM16 Agent APM Feature Crashes IIS App Pool Running Under .NET 2.0 Runtime

As blogged before, the OM16 Agent APM Feature crashes IIS Application Pool when running under .NET 2.0 Runtime. Thanks to my Irish buddy Kevin Greene there are a few workarounds, worked out in great detail.

At this moment Microsoft has acknowledged this bug (AKA ‘hidden feature’) which will be addressed for certain with the release of Update Rollup #3 and perhaps even before that, with the release of a hotfix. However, the release of this hotfix is still under investigation and as such uncertain.

Azure: Everything You Always Wanted To Know But Were Afraid To Ask…

A colleague of mine pointed this website out to me:

It’s the one stop shop for all Azure related services. It describes in telegram style what the related Azure service delivers and – depending on the service – shows one or more links for these categories:

  • Overview
  • Pricing
  • Documentation
  • Limits
  • SLA
  • Service Updates
  • Articles
  • Code Samples

Example, when selecting SQL Database, one is shown this ‘drop down’ menu:

So now one only has to bookmark this website and you have all the information you need for Azure.

Updated/New MPs For Microsoft’s 2016 Releases (And Others)

In the past weeks Microsoft has released MPs covering their 2016 releases of well known products and services.

Since I don’t prefer to reinvent the wheel, I’ve borrowed the list from Daniele Grandini’s blog. So all credits for this list should go to him, not me.

Other updated MPs are:

Cross Post: Registry Tweaks For SCOM 2016

Last week Kevin Holman wrote a posting about registry tweaks for SCOM 2016. For anyone running a SCOM 2016 environment, that posting is a MUST read.

Cross Post: OM16 Agent Crashing Legacy IIS Application Pools

My Irish buddy and fellow MVP Kevin Greene has posted an article on his blog about SCOM 2016 Agents crashing legacy IIS Application Pools.

Kevin investigated this issue thoroughly before coming to this conclusion. So this is not something to be taken lightly. However, his investigation showed him:

  1. The SCOM 2016 Agent in general being the culprit;
  2. The APM component specifically being the real cause of crashing legacy IIS Application Pools;
  3. Installing the SCOM 2016 Agent with the NOAPM = 1 switch works around this issue.

APM stands for Application Performance Monitoring, enabling organizations to deeply monitor .NET based applications, from server to client and back. Later on Microsoft also enabled APM to monitor J2EE based applications.

The APM component is part of the SCOM Agent and is installed by default when a SCOM Agent is installed. By default the APM service is switched off. But now with the SCOM 2016 Agent, the APM component is buggy and causes legacy IIS Application Pools to crash EVEN WHEN THE APM COMPONENT IS SWITCHED OFF (by default)…

In Kevin’s same posting he also tells you how to remove APM from SCOM 2016 Agents. So his posting is a MUST read.

At this moment Microsoft is aware of this bug and working hard on a fix. For now there is no known time frame when the fix will be ready and released.

!!!Security Issue!!! SHA-1 Algorithm Is Unsecure. OM12 R2 UR#12 / OM16 UR#2 Fixes It

Issue
SHA-1 is an outdated cryptographic hash function. Last week Google hammered another nail in it’s coffin. So SHA-1 is really dead now, no mistake about that.

Thing is that SCOM uses SHA-1 itself for monitoring UX based workloads!

SHA-2 to the rescue?
Gladly, UR#12 for SCOM 2012 R2 and UR#2 for SCOM 2016 fixes this issue by replacing SHA-1 by SHA256, member of the SHA-2 family.

What to do?
Simple! Whenever running SCOM 2012 R2 and/or SCOM 2016 AND monitoring UX based workloads, roll out the respective UR and follow this article on the SCOM Team Blog about how to replace the SHA-1 certificates with the SHA256 certificates.

Do I need to?
Well, it depends. When you like flipping burgers as a next career move, then don’t. When you like your current career, then do it ASAP…
