What is SCOM?
System center operations Manager (SCOM) is a part of the Microsoft System center suite. SCOM is a tool that allows us to monitor computer, network device, services from a single console. SCOM 2012 not only help you improve application performance monitoring (APM) and network device monitoring, but also allows for better interface monitoring. Moreover, there is no single point of failure which can take the whole system down, thus making SCOM 2012 more reliable for users. Participants learn how to perform SQL clustering, designing and capacity planning for SCOM. Apart from integration with SCSM, SCVMM and DPM, it also allows for dashboard integration with SharePoint web part.
Different versions of SCOM are MOM2000;MOM2005,SP1; SCOM 2007 SP1,R2,CU1 to CU7; and SCOM 2012 SP1,R2.
Version history of SCOM
Microsoft Operations Manager
SCOM’s roots are from a network management system named SeNTry ELM from a company named Serverware Group plc.
In 1998, Mission Critical Software acquired the rights to SeNTry ELM, adapted it and changed the name to OnePoint Operations Manager.
In 2000, Mission Critical Software merged with NetIQ and sold the rights to OnePoint Operations Manager.
In 2001, Microsoft renamed the product to Microsoft Operations Manager (MOM) and released it.
MOM worked in concert with two other Microsoft programs: Systems Management Server (SMS) 2.0 and Application Center 2000. MOM simplified the management of servers and applications. It contained the same basic features as SCOM 2016, but with less scope due to the limited number of management packs.
MOM 2005 SP1: In 2005, Microsoft released MOM 2005 Service Pack 1 with several enhancements, including mutual authentication, agent proxy capabilities, a secure communications channel and secure credential storage. Microsoft introduced several new features, such as an action account, tasks and a reporting database that stored data and generated reports to the reporting console.
SCOM 2007: In 2007, Microsoft renamed MOM to System Center Operations Manager (SCOM). The company added the command shell to this update that connected to Windows PowerShell.
SCOM 2012: In 2012, Microsoft released System Center 2012 and introduced high availability, application performance monitoring, dashboards, network device monitoring and Java application monitoring to SCOM. Microsoft improved the installation process with a prerequisite checker in the installation wizard.
SCOM 2012 R2: In 2013, Microsoft released System Center 2012 R2, which included improved fabric monitoring for private clouds and integration with development tools for application troubleshooting.
SCOM 2016: In October 2016, Microsoft released System Center 2016 with more advanced cross-platform infrastructure and workload monitoring. Microsoft further integrated SCOM with the rest of System Center and extended its tool set to provide a more consistent monitoring system.
Feature of SCOM 2012:
- Allows application performance monitoring.
- Eliminate concept of RMS, which was earlier the cause of downtime incase of single point failure.
- Allows monitoring of networking devices.
- Resource Pool concept.
SCOM environment comprises of Operational database, RMS Server, Management server, Management group, Monitor & rules, Gateway server, Dataware house, Reporting server etc…. A basic SCOM installation includes several components. A management server handles the essential administration and connection to databases. The operational database provides an SQL database for current reporting. The data warehouse database holds SQL data collected over long-term reporting. A reporting server queries the databases and produces detailed reports delivered to administrators. The IT department can install these components on one server or across several servers for scalability.
Microsoft System Center Operations Manager (SCOM) is a component in the Microsoft System Center suite of enterprise management software. SCOM deploys, configures, manages and monitors the operations, services, devices and applications of many systems within an enterprise through a single management console.
How SCOM works
Every enterprise relies on its underlying services and applications for everyday business and user productivity. SCOM is a monitoring and reporting tool that checks the status of various objects defined within the environment, such as server hardware, system services, operating systems (OSes), hypervisors and applications. Administrators set up and configure the objects. SCOM then checks the relative health — such as packet loss and latency issues — of each object and then alerts administrators to potential problems. Additionally, SCOM offers possible root causes or corrective action to assist troubleshooting procedures.
Additional changes in SCOM 2016
Microsoft adjusted SCOM 2016 to have less dependency on physical networking infrastructure. For example, administrators can deploy SCOM updates through rolling cluster upgrades to update multiple servers simultaneously without downtime.
Microsoft also tightened the connection between SCOM and its Azure-based Operations Management Suite tool to let SCOM move information to OMS for further analytical capabilities.
Microsoft upgraded its management packs so they can be finely-tuned using alert data. Management packs can now disable alert types so users can choose which alerts require their attention. Existing management packs will offer alerts for upgrades.
Microsoft released a management pack to monitor advanced features in Windows Server 2016, such as host guardian service to avoid downtime for shielded virtual machines (VMs).
SCOM 2016 limitations
Microsoft provides recommended limits to SCOM 2016 monitoring, such as 100,000 agentless computers per management group.
Agent-managed and Unix/Linux limitations depend on the number of open consoles. SCOM 2016 monitors up to 6,000 nodes with 50 open consoles or 15,000 nodes with 25 open consoles. SCOM 2016 monitors the performance of about 700 applications. SCOM 2016 monitors 3,000 computers with agents per management server.
Prerequisites for SCOM :
Prior knowledge of SCOM 2016 is not required to get into SCOM Online training.
Careers at SCOM :
The average pay for a Sales Operations Manager is Rs 696,719 per year. For the first five to ten years in this position, pay increases steeply, but any additional experience does not have a big effect on pay.
