evmviewer - View events SYNOPSIS
Opening the viewer as a process: /usr/share/sysman/menu/tasks/evmviewer/evmviewer [-ui ui_mode] [-display display_name] [-filter filter_expr] [-host host- name[:port_no]]... [-input logfile] Opening the viewer using the SysMan Menu: /usr/sbin/sysman -menu "View events" [-ui ui_mode] [-display display_name] [-filter filter_expr] [-host hostname[:port_no]]... [-input logfile] Opening the viewer using a SysMan Menu accelerator: /usr/sbin/sysman [-accel] event_viewer [-ui ui_mode] [-display display_name] [-filter filter_expr] [-host hostname[:port_no]]... [-input logfile] OPTIONS
Specifies the user interface to be invoked. The choices are: Specifies command line interface. Specifies graphical user interface. Speci- fies Java interface. Specifies the display screen on which evmviewer displays its window. If the display flag is not specified, the dis- play screen specified by the DISPLAY environment variable is used. The display_name variable has the format hostname:number. The default is :0. For more information, see the X(1) reference page. Initializes the display only with events which match the filter_expr. See the EvmFilter(5) reference page for the syntax of filter_expr. Attempts to connect to the EVM daemon on the host hostname, rather than to the local daemon. This option may be repeated to obtain events from several hosts. If the name of the local host is included, a remote connection to the local daemon is made. If specified, use port_no for TCP communication with remote clients. If not specified, use the evm port number found in /etc/ser- vices. If not specified, and no entry is found in /etc/services, use the reserved value of 619. Retrieve events from the file log- file rather than from the event logs. When operating in the gui mode, the evmviewer application also supports all of the standard flags described in the X(1) reference page. OPERANDS
None DESCRIPTION
The evmviewer is a SysMan Menu application that lets you retrieve events and display them. Events may be retrieved from the log files on one or more hosts, or from a file of events stored on your local system. The evmviewer application can be invoked from the SysMan menu or from the command line. To open the evmviewer from the Sysman Menu, do the following: Open the SysMan Menu application. Select Monitoring and Tuning. Select View Events. To open the evmviewer from the command line, use one of the forms shown in the SYNOPSIS section. Online help is available for the evmviewer application. To get help, select Help from any dialog box. ENVIRONMENT VARIABLES
The following environment variables affect the execution of evmviewer: Specifies the display screen on which evmviewer displays its window. This variable has the format hostname:number. The default is :0. For more information, see the X(1) reference page. Specifies the user interface to be invoked. The choices are: Specifies command line interface. Specifies graphical user interface. RESTRICTIONS

evmwatch(1) General Commands Manual evmwatch(1) NAME
evmwatch - monitor EVM events SYNOPSIS
show_template]] filter_expr] channel-list] timeout] reconnect-timeout] DESCRIPTION
The command subscribes to the events specified by the option and passes all events to its stream as they arrive. Output is in the form of raw EVM events. If the option is specified, automatically starts and pipes the event stream into it, producing a formatted display of events. If a show_template argument is supplied, the specified template string is passed to through its own option. See evmshow(1) for more informa- tion. If cannot connect to the EVM daemon, it terminates immediately with an error message. If it succeeds in connecting but subsequently loses the connection, it attempts to reconnect periodically until the reconnect-timeout period expires. The retry period is one second for the first minute, and five seconds thereafter. Options Automatically starts to produce a formatted display of the received events. Subscribes for notification of events matching filter_expr. See EvmFilter(5) for the syntax of filter_expr. By default, the command subscribes for all events. Template string to be passed to if the option is also specified. If the option is not specified, this argument is ignored. See evmshow(1) for a description of the template string. Terminates if no event is processed in the time specified by timeout. The format of timeout is [[[dayshoursminutesseconds, where days, hours, and minutes can be any integer up to 9999, and seconds can be any integer up to 9999999. Omitted values are interpreted as zero. If the converted value exceeds 100,000,000 seconds, it is automatically reduced to that value with no error being reported. The timer is restarted each time an event is received. Retrieves copies of all of the registered event templates from the EVM daemon that match the supplied filter string and for which the user has access authorization. It writes the templates to as EVM events and terminates. Terminates with a zero exit value as soon as the first event matching filter_expr is processed. Specifies the period for which should continue to attempt to reconnect if the connection to the EVM daemon is lost. The format of reconnect-timeout is [[[dayshoursminutesseconds, where days, hours, and minutes can be any integer up to 9999, and seconds can be any integer up to 9999999. Omitted values are interpreted as zero. If the converted value exceeds 100,000,000 seconds, it is automatically reduced to that value with no error being reported. If reconnect-timeout is zero, terminates immediately if a disconnection occurs. If this option is not specified, the reconnec- tion timeout is set to five minutes. RETURN VALUES
The following exit values are returned: Successful completion An error occurred, including timeout. EXAMPLES
o The following example watches for all events with a priority of at least 200 and displays them on Events are piped automatically through to produce a formatted event display. o The following example shows how waits until another process posts a particular event and then continues. Redirection of output to implies that the content of the event is of no concern. The following script builds on the prior example. It waits for five minutes (300 seconds) for the event to occur or exits as soon as the event happens. o The following shell script waits for up to five minutes (300 seconds) for a pulse event to be received. Each time the pulse arrives, the timer is reset and waits for the next pulse. If the timer expires, terminates with an error code, a warning is displayed, a high priority event is posted, and the script exits. o The following example lists the names of all registered events that the user is authorized to access. WARNINGS
The command rejects attempts to output raw events to a terminal device. The command receives events only for which the user has access authorization. See evm.auth(4) for details of access authorization. FILES
