The Runtime Monitor allows you to monitor server events and statistics, which may help you anticipate and prevent server problems.
Starting the Runtime Monitor
Double-click the Servers icon.
Double-click the server you want to monitor.
The Runtime Monitor can connect to other EAServer instances via an IIOP listener. The server configuration identifies the host and port number to which the Runtime Monitor attempts to connect.
Click the Runtime Monitor icon to display these folders:
Packages Monitor events and statistics for a specific package, or for all packages on the server. See “Monitoring component activity” for more information.
Connection caches Monitor a specific connection cache or statistics for all caches, as described in “Monitoring connection caches and managed connection factories”.
Managed Connection Factories Monitor connection factories or statistics for all connection factories, as described in “Monitoring connection caches and managed connection factories”.
Network Monitor protocol-specific session information, as described in “Monitoring network connections”.
Instance Pools Monitor component instance pool activity, including the total number of instances in each pool, and the number of instances for each component assigned to the pool.
Active Component Models Highlight this folder to display the component models that are in use. Information about each model is displayed in the right pane.
If you are running Java or EJB components, you can determine the version of the server’s Java virtual machine.
If you are running PowerBuilder components using a version 9.0.1 (build 6514) or later PowerBuilder Virtual Machine (PBVM), you can determine the version and build number of the PBVM that is running the component.
Statistic counters Some monitoring folders display counters, which display a monitored statistic, such as component invocations or HTTP requests. When you highlight the folder, the current values of the counters display on the right side of the window. There are several types of counters:
Snapshot counters represent values at a particular point in time that are likely to either increase or decrease. For example, number of sessions, number of instances active, number of active connections, and so on. Snapshot counters do not display information when set at the per-second rate; instead they display “N/A.”
Cumulative counters represent values that always increment and never decrement. For example, number of invocations, number of connections opened, number of network requests, bytes read and written, and so on. Cumulative counters display both per-second and counter information.
Peak maximum counters represent the total value since starting the server.
Last maximum counters represent the total value since starting the runtime monitor, and is not useful when there are multiple monitoring clients.
Refreshing displayed statistics You can refresh or change the counters view by choosing any of these options from the File menu:
View Values View the values in a separate dialog that automatically refreshes according to the refresh rate, which you can select from a drop-down list. If the group contains subgroups, expand those subgroups until you see the values.
