NAME

evmdaemon.conf — EVM daemon configuration file

SYNOPSIS

authentdir directory sourcedir directory authtimeout time_seconds synctimeout time_seconds start_sync command max_msg_size message_size filterdir filter_dir activity_monitor { name detector period detect_period threshold detect_thold holdoff detect_delay } service { name service_name command service_command }

DESCRIPTION

The Event Manager (EVM) daemon configuration file, evmdaemon.conf, is a text file that contains commands used to configure and start the Event Manager. Any portion of a line from an unquoted number sign (#) to the end of line is a comment. Blank lines are ignored. The following commands are recognized:

authentdir directory

Names the directory that is used to hold temporary authentication files. The default is /var/evm/shared.

sourcedir directory

Names the root of the directory structure that should be searched for event template files. The default is /usr/share/evm/templates.

authtimeout time_seconds

Time to wait for a newly established client to respond to an authentication request. The default is 10 seconds.

synctimeout time_seconds

Time within which a synchronized client must achieve synchronization completing a connection request and subscribing for events. The default is 30 seconds.

start_sync command

The complete command line for programs that should be started as synchronized clients when the daemon starts. This command should be enclosed in double quotation marks (").

max_msg_size message_size

The maximum number of bytes the daemon will accept from any connection in a single message. If a client attempts to send a message that is longer than the specified size, the daemon immediately terminates the connection without reading the message. This keyword can be used to limit the sizes of events that can be posted, to prevent the daemon from consuming excessive amounts of memory or CPU time by handling very large events.

Note: Setting this value too low may prevent normal system events from being posted.

If this keyword is not specified, a default value of 2 Mbytes is used. If the keyword is specified and the supplied value is less than 200 Kbytes or greater than 10 Mbytes, it is set automatically to the closest of those values.

The daemon accepts messages up to 200 bytes longer than the specified size to allow for communication protocol overhead.

filterdir filter_dir

A colon-separated list of directories to be searched for filter files in place of the standard locations. If specified, the daemon uses this value internally to evaluate filter strings that reference pre-created filter files, and also passes it to service programs such as the event retrieval service program, evmget_srv, by exporting the environment variable EVM_FILTERDIR. This makes the path available to the event channels' get-function scripts. The default value for this keyword is /usr/share/evm/filters. See the evmfilterfile(4) manpage for more information.

If this keyword is not specified, a default value of 2 Mbytes is used. If the keyword is specified and the supplied value is less than 200 Kbytes or greater than 10 Mbytes, it is set automatically to the closest of those values.

The daemon accepts messages up to 200 bytes longer than the specified size to allow for communication protocol overhead.

activity_monitor

A parameter group that controls a daemon event monitoring facility. An activity_monitor definition consists of:

name detector

The type of detector controlled by the group parameters.

period detect_period

The size, in minutes, of a periodically sliding time window over which events will be counted.

threshold detect_thold

The number of events that will activate the monitor if counted in period.

holdoff detect_delay

The time delay, in minutes, after activation of the activity monitor occurs before monitoring is resumed. The evmreload command will reset the delay.

service

Defines services that are available through the daemon. A service definition consists of the name of the service and the command line that will be invoked when this service is requested. User-defined services are not currently supported.

A service definition consists of:

name service_name

The name given to the service.

command service_command

The command to be invoked when this service is requested. This command should be enclosed in double quotation marks (").

The keywords described may be entered in a case-insensitive manner. The allowable strings and the minimum number of characters is shown in the following table. A minimum of zero (0) indicates that all characters are required.

The activity monitor detectors recognized, and the action taken when the monitor is activated are the following:

EXAMPLES

This is an example of an EVM daemon configuration file that does the following:

1.

Specifies that event templates are found in the directory /usr/share/evm/templates.

2.

Starts the EVM Logger and the EVM Channel Manager as synchronized clients when the daemon is started.

3.

Defines a service available through the EVM daemon.

4.

Establishes an activity monitor that will alert the system administrator if 500 events occur in any 10 minute span. Once the system administrator has been alerted, the activity monitor will remain dormant for four hours.

# Event template directory: sourcedir "/usr/share/evm/templates" # Start the EVM Logger as a synchronized client: start_sync "/usr/sbin/evmlogger \ -o /var/run/evmlogger.info \ -l /var/evm/adm/logfiles/evmlogger.log" # Start the EVM Channel Manager as a synchronized client: start_sync "/usr/sbin/evmchmgr \ -l /var/evm/adm/logfiles/evmchmgr.log" # Event retrieval service definition: service { name event_get command "/usr/sbin/evmget_srv" } # Set up an activity monitor. activity_monitor { name event_count # currently the only supported monitor period 10 # count over a 10 minute period threshold 500 # perform action after 500 events holdoff 240 # wait 4 hours before resuming }
