Main Service Manager is a central component, one per each user. Location of MainSM is configurable.
Service Managers are located on each site of the Grid, typically one Computing Element machines.
Local Monitors are located on each Worker Node where there are monitored application process.
In the process of development of Grid applications, various tools are helpful in order to find bugs in the application (debuggers) or to examine if the application is performing well (performance analyzers). Such tools require a facility that allows to obtain the information about the running application or even to manipulate its behavior.
This functionality is provided by the
OCM-G Monitoring System
The OCM-G provides various services, for obtaining information or manipulating target application. The information obtained from the OCM-G can be presented by tools conntected to the OCM,, such as G-PM performance analyzer, in the form of various charts.
Support for Grid applications running across multiple sites.Techniques for data rate reduction ensure extremely low overhead and high responsiveness.Flexible, services-driven rather than fixed-metrics-driven design Extendibility: the OCM-G can be extended with additional services, loaded dynamically at run-time.Compact and secure design: the OCM-G runs as a set of user processes, which use a fast socket-based communication mechanism. At the same time, state-of-the-art techniques are applied to ensure secure communication. No special access rights, open ports on firewalls, or other potential security holes) are required.Design as autonomous infrastructure exposing a standard interface OMIS, which minimizes the effort of porting OMIS-based tools across platforms and enables interoperability of multiple tools monitoring a single application.
