Update on APM fix for agent crashing issue shipped in UR3

Microsoft Operations Manager and OMS -

Overview of the .NET 2.0 fix that was shipped in UR3

We have been investigating this issue actively and this fix has not solved the issue completely. We are actively working to resolve the issue and release a hotfix soon.

Workarounds:

  • SCOM 2016 Agent can be replaced with SCOM 2012 R2 Agent, it’s forward-compatible with SCOM 2016 Server and APM feature will continue to work with the older bits
  • SCOM 2016 Agent can be reinstalled with NOAPM=1 switch in msiexec.exe setup command line, APM feature will be excluded from setup

 

Additional issues along with the workaround

SharePoint Central Administration site stops working when SCOM 2016 Agent is installed onto the server

  • Although SCOM 2016 Agent installs APM component in the disabled state by default, it adds a registry setting to load inactive APM into IIS Application pools
  • If APM is not yet configured for this server, those application pools will only have APM loaded in inactive state without any monitoring
  • The issue has been reported that inactive APM may crash SharePoint Central Administration v4 application pool and prevent this application from starting

Workarounds:

  • If APM feature is required on that server: downgrade SCOM Agent to 2012 R2 and continue monitoring;
  • If APM feature is not required on that server: keep SCOM 2016 Agent and re-install it with “NOAPM=1” in the setup command line

 

Web Site crashes during startup when SCOM 2016 Agent is installed onto the server

  • Although SCOM 2016 Agent installs APM component in the disabled state by default, it adds a registry setting to load inactive APM into IIS Application pools.
  • If APM is not yet configured for this server, those application pools will only have APM loaded in inactive state without any monitoring.
  • If application pool account has no access to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\System Center Operations Manager\12\APMAgent registry key, inactive APM won’t be able to read that key and this application pool process may crash.

Workaround:

  • Add “Read” access permission for the application pool account to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\System Center Operations Manager\12\APMAgent

APM fix for agent crashing issue shipped in UR3 is not completely resolved

Microsoft Operations Manager and OMS -

The Application Performance Monitoring (APM) feature in System Center 2016 Operations Manager Agent causes a crash for the IIS Application Pool that’s running under the .NET Framework 2.0 runtime. A fix for this issue was made in UR3, however the fix does not seem to solve the issue completely. We are investigating this issue and we would be releasing a hotfix with a resolution soon.

Unlocking the full potential of System Center Operations Manager: introducing the free Squared Up Community Edition license

Microsoft Operations Manager and OMS -

This is a special guest blog from Squared Up

Since founding Squared Up in 2011, we’ve been on a mission to transform the way enterprises interact with their monitoring data and, in doing so, have enabled hundreds of clients worldwide to unlock the full potential of System Center Operations Manager (SCOM).

 “Together with SCOM, Squared Up is a key component in our strategy to deliver end-to-end monitoring for our entire set of enterprise applications – Shawn Williams, Systems Engineer, ITaP, Purdue University.”

We’ve always believed that no other enterprise-class monitoring tool offers the same power, flexibility and sheer breadth and depth of cross-platform monitoring capabilities as SCOM. Because of this, we believed that by building on top of SCOM we could take on the huge challenges of application monitoring in the enterprise environment.

“Blackboard is one of our key-line-of-business applications and SCOM, together with third party Management Packs, is able to provide us with detailed insights across the entire stack, from our F5s at the front-end, all the way through to the virtualization at the backend, and all of that data is then surfaced via Squared Up – Shawn Williams, Systems Engineer, ITaP, Purdue University.”

First up, we delivered a blazingly-fast, multi-platform HTML5 web console, which we then enhanced with powerful new features like interactive performance reporting from the Data Warehouse, export to Excel, seamless Visio integration and, above all, the ability to easily build and publish custom dashboards.

 

“One of the first things Squared Up allowed us to do was much more easily expose availability and uptime reporting to the wider business, both at a managerial level and for our Service Desk –  Shawn Williams, Systems Engineer, ITaP, Purdue University.”

With the simultaneous release of SCOM 2016 and Squared Up Version 3.1, we’ve now taken things to the next level.

Working in close conjunction with the SCOM Engineering Team and leveraging the significant performance enhancements introduced in SCOM 2016, Squared Up is now faster and more powerful than ever.

Taking full advantage of SCOM’s extremely powerful capabilities, Squared Up goes far beyond just enabling HTML5 access, allowing you to:

–  Dynamically map your applications and view live health states across the full stack, irrespective of the underlying technologies, all powered by your existing SCOM Agent.

 

 

“VADA is a tremendously powerful tool, allowing us to get a definitive handle on the exact topology and dependencies of all of our applications, of which there are several hundred – Shawn Williams, Systems Engineer, ITaP, Purdue University.”

– Integrate OMS and unify SCOM and OMS data behind a single-pane-of-glass User Interface

“As our monitoring strategy evolves, OMS is now starting to supplement our SCOM data with things like Security & Audit and Change Tracking, which will provide us with value-add insights on top of our existing SCOM data. The key to realizing that value is being able to deliver the data to our users in a single-pane-of-glass UI thanks to Squared Up – Shawn Williams, Systems Engineer, ITaP, Purdue University.”

– Provide top-to-bottom, full-stack visibility via technology-specific, customised drilldowns

 

 

“The speed, ease of use and vendor-neutral nature of Squared Up means we’ve been able to successfully bring non-Microsoft engineering teams – such as our Linux teams – into our SCOM-centric monitoring strategy, with a common portal through which all of our cross-platform monitoring data is consumed. That really helps in our efforts to break down siloed thinking and “Us versus Them” mentality within the organization – Shawn Williams, Systems Engineer, ITaP, Purdue University.”

We’re now five years into our mission to radically change the landscape of enterprise monitoring and, together with the release of SCOM 2016 & Squared Up Version 3.1, we believe this marks the perfect moment to unlock the potential of SCOM for literally every customer worldwide.

So, together with the support of Microsoft, we’re delighted to unveil our new, completely free, Community Edition license, which supports both SCOM 2012 and SCOM 2016, and allows you to deliver;

– Full HTML5 Web Console for SCOM

– Unlimited custom dashboards

– Interactive Performance Reporting from the Data Warehouse

– Visio Integration

– Data on Demand

– Total Dashboard Architecture

– Mobile & Tablet Access

– and lots, lots more

You can read more about our Community Edition license and request one for yourself via our website.

We’re looking forward to welcoming you into our Community and to helping you solve the challenges of Enterprise Application Monitoring.

APM feature in SCOM 2016 Agent may cause a crash for the IIS Application Pool running under .NET 2.0 runtime

Microsoft Operations Manager and OMS -

Summary

APM feature in SCOM 2016 Agent may cause a crash for the IIS Application Pool running under .NET 2.0 runtime.

Cause

Several callbacks within APM code of SCOM 2016 Agent utilize memory allocation that’s incompatible with .NET 2.0 runtime and may cause an issue if this memory is later accessed in a certain way. Those particular modifications were added in SCOM 2016 Agent and are not present in SCOM 2012 R2 Agent.

Resolution

The fix for this issue is to be provided with SC 2016 OM Update Rollup 3. The aforementioned code paths will not be executed if the Application Pool is running under .NET 2.0 Runtime. We are also evaluating to release a hotfix for this issue.

Workaround

There are several workarounds for this issue:

  • Application pool can be migrated to .NET 4.0 Runtime;
  • SCOM 2016 Agent can be replaced with SCOM 2012 R2 Agent, it’s forward-compatible with SCOM 2016 Server and APM feature will continue to work with the older bits;
  • SCOM 2016 Agent can be reinstalled with NOAPM=1 switch in msiexec.exe setup command line, APM feature will be excluded from setup;
