This guide will help you get started with setting up Alert Triggers for real-time monitoring and notifications in LoadGen Cloud. Alert Triggers are an integral component of the LoadGen End-to-End Monitoring system, allowing you to stay on top of performance issues as they occur.
Understanding Alert Triggers
Alert Triggers in LoadGen Cloud act as sentinels, meticulously monitoring your testing environment to notify you of critical events or significant performance metrics. At their core, triggers are conditions that, when met, prompt a predefined action, such as sending an alert. Currently, LoadGen supports email and webhook notifications, with the roadmap including expansion to Text messages (SMS) and WhatsApp for a more integrated communication approach.
Triggers can be set for two main categories:
- User Experience Measurements: These are focused on how the end-users interact with the system and how the system responds. Triggers can be set for scenarios such as login times, page load durations, or any custom user interaction metric.
- Performance Metrics: This category zeroes in on the technical performance parameters like CPU usage, memory consumption, response times, etc. These metrics are crucial for backend monitoring and ensuring the system's health and efficiency.

Creating a message within a trigger is a dynamic process. LoadGen allows the use of various variables, which you can insert by prefixing them with a dollar sign ($). These variables can pull data directly from your data sources, enabling you to customize messages with details like the specific metric that triggered the alert, the time of the event, and the affected user or system.
The versatility of the LoadGen Alert system is further enhanced by its ability to integrate these triggers into Alert Profiles. An Alert Profile is an overarching entity that defines:
- Alert Type: Categorizing the severity of the alert as Information, Warning, Error, Critical, or Success. This helps in prioritizing the alerts and taking appropriate action.
- Alert Configuration: Associating the alert with either User Experience Measurements or Performance Metrics. Only triggers designed for the selected configuration will be available in the profile, ensuring relevance and clarity.
- Expression Editor: A tool within the Alert Profile where you can define the logic for when an alert should be triggered. For instance, you might set an alert to trigger when the 'Starting loadgen.com' measurement exceeds a threshold of 1 second. This conditional approach allows for fine-tuning and precise control over the alerting behavior.
With these features, LoadGen Cloud's Alert Triggers empower you to create a responsive and proactive monitoring environment. By swiftly notifying the relevant personnel or systems, you can ensure that any potential issues are addressed promptly, maintaining the integrity and performance of your testing landscape.
LoadGen Cloud offers two pivotal features for monitoring and response: Alert Profiles and Alert Triggers.
- Alert Profiles: categorize and manage the severity of incidents, ensuring prioritized attention. Read this article for setting up an Alert Profile.
- Alert Triggers: serve as the condition-based mechanisms that prompt notifications. Together, they form a comprehensive alerting system that keeps stakeholders informed and ready to act, thus preserving the efficiency and reliability of the testing process.

Best Practices
- Consistency in naming: Use clear, consistent naming conventions for triggers to easily identify their purpose.
- Tailored messages: Craft your messages to provide all necessary information for quick understanding and response.
- Variable usage: Make the most out of variables to automate and personalize alert content.
- Regular reviews: Periodically review your triggers to ensure they remain relevant and adjust as needed.
