Bsvcadm

Show Answer

Correct Answer: A

How to Set Up Email Notification of SMF Transition Events

This procedure causes the system to generate an email notification each time one of the services or a selected service has a change in state. You can choose to use either SMTP or SNMP. Normally, you would only select SNMP if you already have SNMP configured for some other reason.

By default, SNMP traps are sent on maintenance transitions. If you use SNMP for monitoring, you can configure additional traps for other state transitions.

1. Become an administrator or assume a role that includes the Service Management rights profile.'

2. Set notification parameters.

Example 1:

The following command creates a notification that sends email when transactions go into the maintenance state.

# /usr/sbin/svccfg setnotify -g maintenance mailto:sysadmins@example.com

Example 2:

The following command creates a notification that sends email when the switch service goes into the online state.

# /usr/sbin/svccfg -s svc:/system/name-service/switch:default setnotify to-online \ mailto:sysadmins@example.com

Note: The svccfg command manipulates data in the service configuration repository. svccfg can be invoked interactively, with an individual subcommand, or by specifying a command file that contains a series of subcommands.

Changes made to an existing service in the repository typically do not take effect for that service until the next time the service instance is refreshed.
