module: nagios
short_description: Perform common tasks in Nagios related to downtime and notifications.
description:
- "The C(nagios) module has two basic functions: scheduling downtime and toggling alerts for services or hosts."
- The C(nagios) module is not idempotent.
- All actions require the I(host) parameter to be given explicitly. In playbooks you can use the C({{inventory_hostname}}) variable to refer
to the host the playbook is currently running on.
- You can specify multiple services at once by separating them with commas, .e.g., C(services=httpd,nfs,puppet).
- When specifying what service to handle there is a special service value, I(host), which will handle alerts/downtime/acknowledge for the I(host itself),
e.g., C(service=host). This keyword may not be given with other services at the same time.
I(Setting alerts/downtime/acknowledge for a host does not affect alerts/downtime/acknowledge for any of the services running on it.)
To schedule downtime for all services on particular host use keyword "all", e.g., C(service=all).
options:
action:
description:
- Action to take.
- servicegroup options were added in 2.0.
- delete_downtime options were added in 2.2.
