class spicerack.alerting.AlertingHosts(alertmanager_hosts: AlertmanagerHosts, icinga_hosts: IcingaHosts)

Bases: object

Operate on Alertmanager and Icinga via their APIs.

Initialize the instance.

Parameters:

• alertmanager_hosts (spicerack.alertmanager.AlertmanagerHosts) -- the Alertmanager hosts to talk to.

• icinga_hosts (spicerack.icinga.IcingaHosts) -- the Icinga hosts to talk to.

downtime(reason: Reason, *, duration: timedelta = datetime.timedelta(seconds=14400)) → str

Issue a new downtime.

Parameters:

• reason (spicerack.administrative.Reason) -- the downtime reason.

• duration (datetime.timedelta) -- how long to downtime for.

Returns:

the downtime ID.

Return type:

str

Raises:

• AlertmanagerError -- if none of the alertmanager_urls API returned a success.

• IcingaError -- if there is a problem downtiming the hosts in Icinga.

downtimed(reason: Reason, *, duration: timedelta = datetime.timedelta(seconds=14400), remove_on_error: bool = False) → Iterator[None]
