Performance monitoring

Performance monitoring eases maintaining mission-critical services by not only alerting you when the service goes down but also informing you when the service performance degrades. Degraded performance can cause bad user experience or it even might be foreshadowing a future downtime.

Let's say, your service responds generally in 300 milliseconds, and a higher response time requires attention. But getting notified of every single response with a response time greater than 300 milliseconds would be very noisy. Connection hiccups or momentary issues would cause pointless notifications. But if the service keeps responding late for a certain time, then most probably, there is really an issue.

Enabling performance monitoring

You can enable performance monitoring on the gazer's settings.

There are 3 parameters that need to be set:

• Number of responses required to mark gazer as underperforming
• Time window for checking response times
• Response time limit

Getting notified when a gazer is underperforming

There are two alert source events that can be enabled for performance monitoring alerts. You can choose to be notified when a performance issue starts, ends or both.

In order to add an alert for performance monitoring issues:

1. Go to the Alerts section
2. Click on Add Alert
3. Select the Schedule events on the right side
4. Configure the rest of the alert to suit your needs
