UPDATE: APM Feature in SCOM 2016 Causes Failures in certain IIS Application Pools

Chiyo OdikaOpsMgr, SCOMLeave a Comment

I recently wrote an article about an issue that came to the fore a few months ago relating to how the Application Performance Monitoring (APM) feature in SCOM 2016 agent causes IIS Application pools running under the .NET Framework 2.0 runtime to fail. See the article here: http://www.mrchiyo.com/scom-2016-apm-linked-to-iis-application-pool-failures/. It was expected that a definitive fix for this issue would ship with Update rollup 3 for SCOM 2016. However, update rollup 3 (UR3) for SCOM 2016 was released a few days ago, but it does not appear to have a definitive fix for this issue. See the official update notes here: https://support.microsoft.com/en-us/help/4016126/update-rollup-3-for-system-center-2016-operations-manager   MICROSOFT RECOMMENDED WORKAROUNDS:  Instead of a definitive fix, the Microsoft product team has highlighted various deployment scenarios, and … Read More

SCOM 2016 APM Linked to IIS Application Pool Failures.

Chiyo OdikaOpsMgr, SCOM1 Comment

****UPDATES: See update notes at bottom of the page. I recently encountered an issue where a client running a couple of SharePoint (SP) 2013 Farms was starting to see service failures across the board which adversely affected the availability of their sites. Prior to these failures, this client had recently upgraded their SCOM 2012 R2 environments to SCOM 2016, but there’s no definitive indication of causality as it relates to the SCOM upgrade. This article will provide an in-depth review of the issue, and a tested workaround. I’ll also update it with any new information that the Microsoft product group brings to light.   The Issue: Firstly we determined that the affected sites were based on legacy IIS application pools … Read More

SCOM 2016 Certificate Errors. Event ID 20049

Chiyo OdikaSCOM, WINDOWS SERVERLeave a Comment

In this article, I’ll review SCOM Certificate Event ID 20049. This error event can be seen during an attempt to initiate mutual authentication across untrusted boundaries such as in a gateway or workgroup boundary scenario. In SCOM, certificates will need to be used for mutual authentication between the management servers and any gateway servers/ agents when Kerberos-based mutual authentication is not possible. If there’s an issue with the certificate, mutual authentication will fail, and one of the errors you could likely encounter is as shown below: The event detail reads:  “The specified certificate could not be loaded because the key Usage specified does not meet OpsMgr requirements. The certificate must have the following usage types: Digital Signature, Key Encipherment.” This … Read More

SCOM 2016 – Creating Maintenance Mode Schedules

Chiyo OdikaOpsMgr, SCOMLeave a Comment

Firstly, this shall be short, but sweet. I won’t delve too deep. There’s already an entire bible, okay maybe half, on the subject. Find the authoritative Maintenance mode guide from Microsoft.   Maintenance mode in SCOM enables you to avoid any alerts or errors that might occur when a monitored object, such as a computer, database, cluster, etc. is taken offline for maintenance. Maintenance mode suspends the following features: (SOURCE: TechNet) Rules and monitors Notifications Automatic responses State changes New alerts SCOM 2016 extends the on-demand placement of monitored objects into maintenance mode that existed in previous versions of SCOM, and provides you with the ability to define schedules aligned with your service or maintenance windows, and automatically place monitored … Read More

Why Upgrade to SCOM 2016 – A Review of New Features and Capabilities.

In this article, I’ll highlight, in no particular order, some of the new features in SCOM 2016 that are garnering a lot of attention, and hopefully make a compelling enough case for you the current SCOM Admin, you the curious Admin, you who lies in desperate need of a well-thought out SCOM, and you the former SCOM Admin/user sworn off SCOM and riddled with a thousand critical and crippling assessments of the erstwhile painful to use and implement versions of this paragon of monitoring beauty to actually give it another look…and no SCOM and OMS are not mutually exclusive. Au contraire! And so here it goes… Maintenance Mode scheduling from Monitoring Pane and from Clients Maintenance mode in SCOM enables … Read More

Manually Trigger Object Discoveries in SCOM

Chiyo OdikaOpsMgr, PowerShell, SCOMLeave a Comment

System Center Operations Manager (SCOM), a component of Microsoft System Center 2016 is a software that helps you monitor services, devices, and operations for computers within your infrastructure. This article provides an overview of object discoveries in SCOM and how to manually trigger them. Note that System Center Operations Manager (SCOM 2016) is still in its technical preview (TP5) at the time of this posting but will be launched in a few weeks during Microsoft Ignite 2016. SCOM uses a agent installed on a computer to collect data, compare sampled data to predefined values, create alerts, and run responses. The agent then sends monitoring data to the management server in the SCOM management group. Management servers run various services, including … Read More

OpsMgr 2012 R2 UNIX and Linux Agent Installation. Getting the .rpm and .deb Agent Files

Chiyo OdikaOpsMgr, SCOMLeave a Comment

A client recently asked me how to obtain the agent files for installing UNIX/ Linux OpsMgr agents outside of OpsMgr, and from the command line for instance. After the cursory search for a good article on the web to pass along, I came up with nothing, and decided to correct that. This article will simply walk through how to obtain the agent files. I will not go over agent installation steps as there are numerous articles on the web that sufficiently cover that.   1. Let’s start by obtaining the management packs for UNIX/ Linux. Management packs can be found here: https://www.microsoft.com/en-us/download/details.aspx?id=29696 2. Select the relevant files for your UNIX/ Linux distros. In my case, 2 flavors of CentOS and … Read More
