How can incidents be triggered in PagerDuty?

Incidents in PagerDuty can be triggered through API calls and monitoring tools, which allows for a wide range of automated notifications and responses. API integrations enable systems and applications to communicate directly with PagerDuty, creating incidents automatically based on predefined conditions. This automation is crucial in modern incident management, as it helps ensure that issues are promptly identified and addressed without the need for manual intervention.

Additionally, monitoring tools can send alerts to PagerDuty when specific thresholds are met or anomalies are detected, facilitating timely responses to incidents such as service outages, performance degradation, or security threats. This versatility is essential for organizations seeking to maintain uptime and performance across their services.

The other methods mentioned in the choices, such as solely relying on manual escalation or manual alerts, would limit the effectiveness and speed of incident response, making it less efficient in dynamic production environments. Relying exclusively on emails or certain manual triggers would not accommodate the higher frequency and complexity of incidents that many organizations face today. Thus, the capability to trigger incidents through API calls and various monitoring tools is vital for effective incident management.
