Using the Caché Monitor 3.2 Caché Application Monitor The Caché Application Monitor (Application Monitor) monitors system- and user-defined metrics. It is an extendable Caché utility that monitors the system for performance and system data, generates alerts, handles notifications, and generates and maintains a persistent repository of all such data. It is a modular system that allows instances of the monitor to run in multiple namespaces concurrently. Each instance of the Application Monitor lets you do the following in each namespace in which it is activated: 1. Register system classes in the local namespace. 2. Activate the system- and user-defined classes you want to monitor. For user-defined classes, you can activate only those classes that you have created in the local namespace; that is, if you created a user-defined class in the USER namespace, you can only activate that user-defined class in the USER namespace. 3. Start an instance of the Application Monitor (%MONAPP) in the local namespace. When an Application Monitor is started in a local namespace, it searches for all classes that have been activated and, for each activated class, it creates sample data in local namespace globals. Monitor metadata is kept in globals ÎSCMonitor(): ÎSCMonitor("Monitor","AppInterval")=300 ÎSCMonitor("Monitor","Interval")=10 ÎSCMonitor("Monitor","Metric","%Monitor.System.Dashboard","Active")=1 ÎSCMonitor("Monitor","Recipients")="" ÎSCMonitor("Monitor","SmtpServer")="" Sample data is kept as persistent data for the sample class. You may view this data by invoking class methods, or via a browser; all sample classes are automatically CSP-enabled. This section discusses the following topics: • Application Monitor Manager – information about managing the Application Monitor • Caché Metrics – information about system-defined metrics • Writing User-defined Monitor Classes – information about writing user-defined monitor classes 3.2.1 Application Monitor Manager The Application Monitor Manager (^%MONAPPMGR) is an interactive utility that lets you perform Application Monitor management functions. Instances of the Application Monitor Manager can be executed in multiple namespaces concurrently with different parameters for each namespace, which enables multiple Application Monitors, each with its own activated classes and notification options, to run simultaneously; the name of the utility is case-sensitive. 1. To start the Application Monitor Manager, enter the following command in the Caché Terminal: USER>do ^%MONAPPMGR 2. The main menu appears. Enter the number of your choice or press Enter to exit the Application Monitor Manager: 1) Manage Application Monitor 2) Manage Monitor Classes 3) Change Default Notification Method 4) Manage Email Options 5) Manage Alerts 6) Exit Option The options in the main menu let you manage the Application Monitor as described in the following table: 22 Caché Monitoring Guide
Caché Application Monitor Option 1) Manage Application Monitor 2) Manage Monitor Classes 3) Change Default Notification Method 4) Manage Email Options 5) Manage Alerts 6) Exit Description Displays the Manage Application Monitor submenu which lets you manage the Application Monitor, as well as activate/deactivate monitor classes and modify the sampling interval. Displays the Manage Monitor Classes submenu which lets you manage systemand user-defined monitor classes in the namespace in which you are running the Application Monitor Manager. Displays the Manage Notification Method submenu which lets you specify how to notify users when system- or user-defined metrics have reached a predetermined threshold. Displays the Application Monitor Email Options submenu. Displays Manage Alerts submenu which lets you manage the notification options (sampling interval, severity level, email). Exits the Application Monitor Manager utility. 3.2.1.1 Manage Application Monitor This submenu lets you manage the Application Monitor and the sampling interval, as well as provides a shortcut to the submenu that lets you activate/deactivate system- and user-defined monitor classes. Enter the number of your choice or press Enter to return to the main menu: Option 1 1) Start Application Monitor 2) Halt Application Monitor 3) Refresh Application Monitor 4) Activate/Deactivate a Monitor Class 5) Set Sample Interval 6) Exit Option This submenu displays a list of menu items that let you manage the Application Monitor as described in the following table: Option 1) Start Application Monitor Description Starts an instance of the Application Monitor in the local namespace. The metrics generated by activated classes are monitored based on the sampling interval, and notifications are sent in accordance with the alert settings. For information about configuring the settings, see: • Change Default Notification Method • Manage Email Options • Manage Alerts 2) Halt Application Monitor Stops the instance of Application Monitor from monitoring metrics in the local namespace.
