Agent Pool Control page content
Figure 3–4 displays the Agent Pool Control page. The page displays data relevant to your current WebSpeed workload and allows you to add or reduce the number of WebSpeed agents currently running.
Use this page to add agents when agent requests are high. You can add agents to the maximum number of agents that your license recognizes. Also, use this page to reduce the agent count during a lag in agent requests. Using the trim feature, you can reduce agents down to the minimum agents property setting.
Figure 3–4: Agent Pool Control page example

The Agent Pool Control page is comprised of these sections:
- An add/trim selection control that you use to specify which activity you want to perform. When you initiate a manual trim request, OpenEdge Management determines which agents to remove. See the "Adding or trimming agents" section for detailed steps.
- The following three distinct, agent-related data summary tables that allow you to review relevant agent-pool specific data quickly:
The changes that you make through add/trim activities can affect the data displayed in these summary tables. The Agent pool summary also allows you to kill a specific agent process. See the "Killing a WebSpeed agent process" section for the detailed steps.
See the "Adding or trimming agents" section for details about how to add or trim agents.
Agent pool initial configuration section
The Agent pool initial configuration section identifies WebSpeed broker configuration properties set in the
ubroker.properties
file. These values display in read-only mode.Table 3–4 identifies and describes each field that displays in the Agent pool initial configuration section.
Agents state section
The Agents state section provides a snapshot of the total number of agents currently associated with a specific agent state. The details related to agents and the number of agents reported reflect real-time data. This data can fluctuate due to changes in the agents' workflow and changes you initiate using the add and trim feature.
Table 3–5 describes each field presented in the Agents state section.
Agent pool summary section and the kill process option
The Agent pool summary section provides:
- Detailed data about each individual agent in the WebSpeed pool associated with a specific WebSpeed broker. Table 3–6 identifies and describes each field displayed in the Agent pool summary section.
- Access to:
- More data about a specific agent.
Use the PID field to access these features. Table 3–6 provides more information about PID.- A control to terminate, or kill, the agent process.
Table 3–6: Agent pool summary field definitions This field . . . Identifies. . . PID The process identifier for this agent. Click on the specific PID number to display a detail page that provides specific information about this agent process and, as necessary, kill the process. See the "Killing a WebSpeed agent process" section for more information. State The current execution state of the agent process. Port The TCP/IP port number that the agent process uses. nRq (Number of Requests) The number of messages sent to the agent process. nRcvd The number of messages received by the agent process. nSent The number of requests sent by the agent process. CPU Usage The percentage of CPU user and system time consumed by a process. Memory Usage The amount of virtual memory (in Kbytes) consumed by a process. Started The time stamp that indicates when the agent process started. If the broker is restarted for any reason, the PID and the Last Change value might change. Last Change The time stamp that indicates when the agent process last changed execution state.
