Configuring WebSpeed Messengers and WebSpeed Transaction Servers
7–34
During the next interval, the request load diminishes somewhat. At the end of the interval, only
20 agents are concurrently busy. The maximum number of busy agents for the interval remains
at 30, since 30 were busy at the start of the interval. Thirty agents are running, and the maximum
busy level is 30. No trimming occurs.
Assume that all employees have to attend a company-wide meeting that begins midway through
the interval. The highest number of agents busy at that same time was 20. At the end of the
interval, there are 30 agents running, with zero agents currently busy. Since the maximum busy
level is 20 (at the start of the interval), and the number of running agents is 30 (all are available
since everyone is at the company meeting), the broker attempts to trim back the number of
agents to 20.
Assume that the company meeting ran for another half-hour, and the entire next interval elapsed
without any requests. The maximum busy agents is zero, with 20 currently running. Since the
Minimum Agent/Server Instances property value is set to 10, the broker attempts to trim back
to 10 agents.
Keep in mind that the lower you set the Agent/Server Auto-trim Interval value, the more quickly
the broker reacts to a drop in the workload. Under a reasonably steady work load, the broker
should trim the number of running agents to the number needed. However, if the workload
fluctuates a great deal and the Agent/Server Auto-trim Interval is set too low, the broker may
trim agents that it must then restart. As stated earlier, repetitive trimming and restarting causes
the system to waste resources on unnecessary process management.
To add or trim WebSpeed agents:
1. Click Resources in the management console menu bar. The main resource types appear in
