Services overview

The MainView Middleware Monitor services do not receive data directly from the Agent. Rather, they register with the MVMM Topic Service as subscribers for the data that they are interested in. The Agent then sends one copy of each piece of information to the MVMM Topic Service, which then forwards a copy to each registered subscriber. This process minimizes the amount of data that needs to be sent and the corresponding overhead. It also makes it much easier to support new technologies since the bulk of the components are unaffected (a new Extension is simply added).

During installation, the following services are installed on the services server:

MVMM Topic Service

The MVMM Topic Service gathers information as topics collected by the Agent and distributes that information to other services. The MVMM Topic Service also manages the topics and makes them available to the clients.

The MVMM Topic Service is responsible for routing data associated with topics to subscribers in real time. The Agents report updated topic data to the MVMM Topic Service, which then passes it along to the Monitor Console or to other services, like the MVMM Event Service. The Topic Service also monitors the agent connection and reports topics based on the status. These topics can be used to trigger actions in the vent Service (such as sending an e-mail message if an agent becomes unresponsive).

MVMM History Service

The MVMM History Service stores and manages a record of topic values according to user specifications. The History Service also makes the data available to clients so that they can analyze and report the historical topic values.

The MVMM History Service stores and maintains topic data for analysis. The Monitor Console uses this information to populate trend charts, views, reports, and graphs. Collecting all information for all possible topics would create a massive database very quickly, so you control what information is collected and how it is stored. MVMM enables you to control high-resolution (short-term-data less than 40 days old) data differently and separately than low-resolution data (long-term-data stored based on database size allocation).

All monitored information is passed from the monitoring extension to the agent. From there it goes to the MVMM Topic Service and on to the History Service. The MVMM History Service passes the data to the database where it is stored. High-resolution data is stored for up to 40 days before it is compressed into low-resolution history.

For information about collecting history data and using trend charts, reports, charts, and views, see the relevant sections in Using.

MVMM Application Service

The MVMM Application Service acts as a proxy for users logged in to the Monitor Console. When an authenticated user opens a view, the Application Service subscribes to all topics needed to populate that view and forwards those to the individual user’s console. The Application Service performs the following functions:

Stores and serves media files (images, views, reports) to the Monitor Console
Supports web browser access to the Monitor Console.
Performs security validation and provides user and group management, rights management, and authentication within MVMM.

The executable file is called Wrapper.exe (Windows) or wrapper (Linux).

Note

The wrapper.ping.timeout parameter in qpas.conf allows you to set the timeout period for a long action.

To avoid timeouts/JVM restarts set:

wrapper.ping.timeout=t

where t is in seconds.

MVMM Event Service

The MVMM Event Service constantly monitors and compares topic values against the trigger conditions of any event rules that have been created. If the incoming data matches one of the event trigger conditions, the defined action is taken. You are not limited by the number of topics for your event rules or by the number or actions that you can take based on an event.

The Event Service can perform the following actions:

Send a Monitor Console alert
Execute an external program
Send an e-mail message
Log a message to a file
Log an SQL message to a file
Write to the event journal
Send a message to a WebSphere MQ queue
Send an SQL message to a WebSphere MQ queue
Send a message to BMC Event Manager (BEM)
Use time to delay a message.

You can define rules that start actions when certain conditions are met. You have full control over defining the conditions, including time-based events and topic-based events.

In the event of a shutdown (hard or soft), the MVMM Event Service recovers the state of any outstanding events at the time of the shutdown. This prevents events from firing multiple times due to shutdown.

All monitored information is passed from the monitoring extension to the agent. From there it goes to the MVMM Topic Service and on to the MVMM Event Service. The MVMM Event Service determines if any events have occurred based on the rules and templates. If so, the MVMM Event Service takes action, which could involve the MVMM Client Gateway Service or the database (depending on the type of action).

MVMM Client Gateway Service

The MVMM Client Gateway Service is used in conjunction with the Event Service for automating events.

The Client Gateway Service is automatically installed along with the Application Service or Event Service. If the Application Service and Event Service are installed on separate machines, each has its own Client Gateway Service.

MVMM ProactiveNet Service

The MVMM ProactiveNet Service publishes MVMM monitored data to TrueSight Infrastructure Management or ProactiveNet that wouldn't otherwise be available to the products. As updates arrive at the MVMM service tier, they are published to the MTM Knowledge Module (KM) running in a Patrol Agent. From that point on, TrueSight Infrastructure Management or ProactiveNet gathers the data from the Patrol Agent.
