| # Send notification in response to a given zevent. |
| # |
| # 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. |
| # |
| # Exit codes: |
| # 0: notification sent |
| # 1: notification failed |
| # 2: notification not configured |
| # 3: notification suppressed |
