Workspaces
The predefined workspaces present information about various aspects of your IBM® MQ (WebSphere® MQ) environment. The table views and graphics within each workspace report the attribute information that you are monitoring. You can use them to do the following things:
- Investigate attribute information relating to a change in a state
- Monitor your system performance to identify bottlenecks and to evaluate tuning decisions
- Select the most effective threshold values for situations that you create
In addition to table views and graphics, a workspace might contain other views, such as a browser view or a take action view that you can use to send commands to the operator console. Note that the descriptions of each workspace apply to the default settings (the components of the workspace in its original configuration). Any changes or updates that you make to a workspace will not be reflected in the description of the workspace. For additional details about customizing workspaces, see the Tivoli Enterprise Portal Help and documentation.
Data collection mode
The IBM MQ Monitoring agent uses two types of data collection mode, which are sampling mode and on-demand mode.
In sampling mode, the agent collects data in the background on an interval basis. Each time you open a workspace with a table based on sampling data, the data displayed in the table is from the most recent interval. For example, if the sampling interval is set to 5 minutes (300 seconds), the data displayed might have been collected up to 5 minutes ago. Sampling mode has the advantage of being able to aggregate data and calculate rates because the new sample can be compared to the old sample and deltas can be taken.
In on-demand mode, the agents collects data at the exact time that a query is issued to it for the data. Each time you open a workspace with a table based on on-demand data, a query for data collection is issued to the agent and the data displayed is collected real time at the time of the query. On-demand mode has the advantage of providing the most current data possible.
For information about which workspace uses sampling mode and which uses on-demand mode, see the appendix that introduces data collection mode in IBM MQ Monitoring Agent User's Guide.
