The UNIX and Linux agents for Operations Manager consist of a CIM Object Manager (that is, CIM Server), and a set of CIM Providers. The management server runs all of the workflows to monitor operating system health defined in our implementation of the UNIX and Linux management packs: The UNIX and Linux Agent does not run a health service, instead it passes information to the Health Service on a management server to be evaluated.

The Windows agent has a Health Service responsible for evaluating the health of the monitored computer. The architecture of the UNIX and Linux agent differs from a Windows agent significantly. The agent communicates with a management server over TCP port 5723.

For more information on heartbeats, see How Heartbeats Work in Operations Manager.įor each agent, Operations Manager runs a health service watcher, which monitors the state of the remote Health Service from the perspective of the management server. The purpose of the heartbeat is to validate the availability of the agent and communication between the agent and the management server. This helps reduce network traffic and the volume of data stored in the operational database.Īdditionally, all agents send a packet of data, called a heartbeat, to the management server on a regular schedule, by default every 60 seconds. For optimized collection rules, data is only transmitted if a sample of a counter differs from the previous sample by a specified tolerance, such as 10%. The agent sends data according to the schedule parameters for each rule and monitor. The agent also sends events, performance, and state data to the primary management server for that agent, which writes the data to the operational and data warehouse databases simultaneously. The Operations Manager agent sends alert and discovery data to its assigned primary management server, which writes the data to the operational database. Communication between agents and management servers These processes monitor and collect event log data, performance counter data, Windows Management Instrumentation (WMI) data, and run actions such as scripts.
To run workflows, the service initiates MonitoringHost.exe processes using specified credentials. On a management server, the service runs monitoring workflows and manages credentials. The Microsoft Monitoring Agent service also runs on management servers. The Microsoft Monitoring Agent service is sometimes referred to as the health service.When the connection is restored, the Microsoft Monitoring Agent service sends collected data and events to the management server. Even when the service is unable to communicate with the management server it reports to, the service continues to run and queues the collected data and events on the disk of the monitored computer.
The Microsoft Monitoring Agent service collects event and performance data, executes tasks, and other workflows defined in a management pack. On a monitored Windows computer, the Operations Manager agent is listed as the Microsoft Monitoring Agent (MMA) service. It allows Operations Manager to monitor Windows, Linux, and UNIX operating systems and the components of an IT service installed on them, like a web site or an Active Directory domain controller. In System Center Operations Manager, an agent is a service that is installed on a computer that looks for configuration data and proactively collects information for analysis and reporting, measures the health state of monitored objects like a SQL database or logical disk, and execute tasks on demand by an operator or in response to a condition.
#Mma manager vs agent upgrade#
This version of Operations Manager has reached the end of support, we recommend you to upgrade to Operations Manager 2019.
