|

|
# This is a generic script than can be symlinked to a file in the
|
||
|
|
# enabled-zedlets directory to have a notification sent when a particular
|
||
|
|
# class of zevents occurs. The symlink filename must begin with the zevent
|
||
|
|
# (sub)class string (e.g., "probe_failure-notify.sh" for the "probe_failure"
|
||
|
|
# subclass). Refer to the zed(8) manpage for details.

# Only one notification per ZED_NOTIFY_INTERVAL_SECS will be sent for a given
|

|
|
# class/pool combination. This protects against spamming the recipient
|
||
|
|
# should multiple events occur together in time for the same pool.
