Service Monitor Agent

Use the Service Monitor Agent page to configure the service monitor agent so it can monitor response time and throughput on selected operations and send the data to its service monitor server.

To view this page in the administrative console, click Servers > Server Types > WebSphere application servers > servername > Service Monitor Agent.

Enable service monitor agent

Enables or disables the service monitor agent. The agent is enabled by default when you configure a stand-alone server or deployment environment profile. It is disabled by default for any new servers you create in the console.

If you need to disable the agent for maintenance or other reasons, the service monitor stops and the agent does not send data to the server.

Enable switch-off timeout

Enables or disables the automatic switch off for a service monitor point. When this option is enabled, the monitor point remains active for the specified number of seconds after receiving the last request. If no more requests are made, the monitor point switches off to preserve system performance.

By default, this option is enabled and set to 120 seconds. Clear the check box to disable the automatic switch off.

Data transmission interval

Specifies the amount of time, in seconds, that can elapse between monitor data transmissions.

By default, the data transmission interval is five (5) seconds. Reduce the interval if you have a high volume of monitor data and find you are missing measurements.
Note: Reducing the interval is not recommended if your system experiences heavy load.

Data buffer size

Specifies the monitor data buffer size, in kilobytes. The buffer stores the monitored Service Component Architecture (SCA) events before they are analyzed and sent to the service monitor server.

By default, the data buffer size is 512 KB. If your system experiences heavy load, consider increasing the buffer size. Note that if there is no memory available, data that exceeds the buffer is discarded.
Tip: Each kilobyte holds approximately 35 response time measurements.
