The Zero Downtime (ZDT) Monitoring Service is a new service in Enterprise Manager 24ai. It is responsible for processing and handling all event management, incident management and notification capabilities in Enterprise Manager. Because it is a ZDT Service, this means it will continue to be operational even during Enterprise Manager 24ai planned maintenance events such as updating to a new Enterprise Manager 24ai Release Update (RU).

With the Zero Downtime Monitoring Service, you will have uninterrupted monitoring, alerting and notification capabilities even when Enterprise Manager 24ai is under planned maintenance for a new release update.

The features provided by Zero Downtime Monitoring Service include:

• Receiving of alerts from agents
• All actions specified in Incident Rule Sets for the targets and groups specified in these Incident Rule Sets. Actions include creation of incidents, event compression, setting of Incident properties, sending of notifications.
• Event compression using Event Compression Policies or event compression rules specified in Incident Rule Sets
• Sending of notifications: Email, SNMP traps, OS Command, Webhooks, Slack
• Opening of tickets using Ticketing connectors
• Sending of events to external systems using Event Connectors
• Priority processing of events based on the targets' Lifecycle Status property

Targets that are in blackout will continue to have monitoring suspended until the blackout ends. After the blackout has ended, monitoring for the target resumes.
