Description
|
|
-----------
|
|
|
|
This script sends notifications about host UP and DOWN events. In comparison
|
|
to just netwatch (`/ tool netwatch`) and its `up-script` and `down-script`
|
|
this script implements a simple state machine. Host down events are triggered
|
|
only if the host is down for several checks to avoid false alerts.
|
|
|
|
Requirements and installation
|
|
-----------------------------
|
|
|
|
Just install the script:
|
|
|
|
$ScriptInstallUpdate netwatch-notify;
|
|
|
|
Then add a scheduler to run it periodically:
|
|
|
|
/ system scheduler add interval=1m name=netwatch-notify on-event="/ system script run netwatch-notify;" start-time=startup;
|
|
|
|
Configuration
|
|
-------------
|
|
|
|
The hosts to be checked have to be added to netwatch with specific comment:
|
|
|
|
/ tool netwatch add comment="notify, hostname=example.com" host=[ :resolve "example.com" ] timeout=5s;
|
|
|
|
It is possible to run an up hook command (`up-hook`) or down hook command
|
|
(`down-hook`) when a notification is triggered. This has to be added in
|
|
comment:
|
|
|
|
/ tool netwatch add comment="notify, hostname=poe-device, down-hook=/ interface ethernet poe power-cycle en21;" host=10.0.0.20 timeout=5s;
|
|
|
|
The count threshould (default is 5 checks) is configurable as well:
|
|
|
|
/ tool netwatch add comment="notify, hostname=example.com, count=10" host=104.18.144.11 timeout=5s;
|
|
|
|
Also notification settings are required for e-mail and telegram.
