Alerting And Dashboarding

You have a Prometheus alerting rule that triggers too frequently during flapping states. Which feature should you use to prevent this without silencing the alert entirely?

You are creating a Grafana dashboard and need to display a gauge showing the current CPU usage percentage from a Prometheus data source. Which function is most appropriate?

You have a recording rule named 'job:node_cpu:avg_rate_5m'. Where is this metric stored once the rule is executed?

When configuring Alertmanager 'group_by' settings, what happens if you include a label that is not present on an incoming alert?

You need to prevent an alert from firing if a maintenance window is active. How should you approach this in Alertmanager?

You have a global Alertmanager configuration where you want to suppress 'DiskSpaceLow' alerts if 'InstanceDown' is active for the same host. Which mechanism accomplishes this?

You notice that recording rules are consuming too much CPU on your Prometheus server. What is the most effective way to reduce the load while keeping data available?

Which file format is used to define Prometheus alerting rules?

You are seeing 'Alerting rule evaluation error' in your logs. What is the most likely cause?

Which Grafana panel type is best for showing a trend of a metric over time?

What is the purpose of the 'labels' field in an alerting rule?

When using the 'repeat_interval' in Alertmanager, what does it define?

You want to notify different teams based on the 'service' label of an alert. Where should you configure this logic?

What happens to your alerts if the Alertmanager configuration file contains a syntax error?

Which annotation is commonly used to provide a human-readable description in an alert?

In Alertmanager, what is the role of the 'continue' field in a route?

Which tool allows you to visualize Prometheus alerts directly in a web UI?

You have a recording rule that uses 'sum() by (instance)'. Why might this be inefficient for large clusters?

You want to ensure that if the Alertmanager cluster loses communication, alerts are still sent. Which configuration helps achieve this?

When configuring a dashboard panel, what is the significance of the 'Legend' field?

What does the 'firing' state mean for an alert?

You have a recording rule that references a metric that doesn't exist. What is the impact?

How do you apply a global notification delay in Alertmanager?

When integrating Grafana with Prometheus, what is the standard authentication method if Prometheus is behind a reverse proxy?

Which of these is NOT a valid Alertmanager receiver type?

Which Alertmanager feature would you use to prevent a 'ServiceDown' alert from firing if a 'GlobalNetworkOutage' alert is already active?

Why would you choose to create a recording rule for a complex PromQL query?

You have a recording rule that fails to evaluate because of a 'labels conflict'. What is the most likely cause?

Which Grafana feature allows you to see data from multiple Prometheus servers on a single panel?

What is the purpose of the 'keep_firing_for' field in an alerting rule?

Which TWO of the following are valid fields in a Prometheus alerting rule definition?

You need to ensure that an alert remains 'firing' for 5 minutes before the Alertmanager is notified. Which field in the Prometheus alerting rule should you configure?

You have two alerts: 'InstanceDown' and 'HighErrorRate'. You want to inhibit 'HighErrorRate' if 'InstanceDown' is firing for the same instance. Where do you configure this logic?

A team wants to visualize metrics from Prometheus in Grafana. What is the standard way to connect these two services?

What is the purpose of a 'grouping' configuration in the Alertmanager 'route' block?

You are creating a recording rule to calculate the rate of requests over 5 minutes. Why would you prefer a recording rule over a direct dashboard query?
