Service Level Objectives (SLOs) are metrics that define the desired reliability and performance targets for a service. Powered by Service Level Indicators (SLIs) such as latency, availability, and error rates, SLOs provide a precise measure of whether your service is meeting its goals. With SLOs integrated into DuploCloud’s Advanced Observability Suite (AOS), you benefit from automated dashboards, real-time performance monitoring, and proactive alerting. These capabilities empower you to continuously monitor and optimize your service's health for a seamless user experience.
DuploCloud streamlines the management of SLOs by integrating them with Grafana, where users can easily create and modify SLO configurations. Instead of manually editing backend files or complex configurations, DuploCloud uses a business form to simplify the process. This form is available in the DuploCloud UI through Grafana, where you can submit your SLO request with a few clicks.
Once submitted, the request is automatically processed by the Duplo-automation service. This powerful service takes care of creating and configuring the necessary backend resources, rules, and alerts based on your input. This automation reduces manual intervention and ensures that your SLO setup is quick, efficient, and error-free.
The SLO Overview dashboard provides a comprehensive view of service performance. It contains high-level data and key metrics for your defined Service Level Objectives (SLO). For each SLO, it tracks the SLI percentage, shows the remaining error budget, and visualizes the SLI percentage as a graph, offering a clear trend of service performance over time.
From the DuploCloud Portal, Navigate to Observability -> Advanced -> Dashboard
Click the SLO link in the Metrics data card or navigate to the SLO Overview dashboard in Grafana. The Grafana SLO Overview dashboard displays.
You can dive deeper into the details of any individual SLO by clicking the View Dashboard button for that SLO on the left-hand side of the SLO Overview dashboard. The SLO details provide a more comprehensive view of the SLO's performance metrics such as the SLO percentage, error budget trend, burn rate, remaining error budget, current burn rate, event rate, etc.
To create an SLO in Grafana, follow the steps below. For more information, see the Grafana SLO documentation.
From the DuploCloud Portal, Navigate to Observability -> Advanced -> Dashboard
Click the SLO link in the Metrics data card or navigate to the SLO Overview dashboard in Grafana. The Grafana SLO Overview dashboard displays.
Click on the Create SLO button located at the top-right corner of the screen. The Dashboard for Managing SLO displays.
Enter the following information about the SLO:
Name: The name of the SLO.
Description: A brief description of the SLO.
Objective: The target goal for the SLO (e.g., 99.9% uptime).
Time Window: The period over which the SLO is measured.
Success Metric: The metric used to track success.
Total Metric: The total metric used to evaluate the SLO.
Click Create/Update SLO. The SLO is created and added to the SLO Overview Dashboard.
Navigate to the SLO Overview dashboard.
Locate the SLO you wish to modify in the list on the left side, and click Edit SLO.
The Dashboard for Managing SLO will appear, displaying the same fields as when you created an SLO. You can now make the necessary changes, such as updating the name, description, objective, time window, type, success metric, and total metric.
After making your changes, click Create/Update SLO to save the updates.
If you wish to delete the SLO, click Delete SLO.
DuploCloud automatically creates alert rules for each SLO, including Critical and Warning alerts. You can view them in Grafana to understand their configurations.
From your Grafana home page, navigate to Alerting -> Alert rules. The Alert rules page displays.
Locate and click the specific SLO (e.g., duplo_slo_slo-auto-14:rjgsrnj6hyf1jef10bf91).
The associated recording and normal alert rules display.
Click on any alert rule to review the alert conditions, thresholds, and labels.
To manage how these alerts are routed, create notification policies based on the SLO service name (e.g., cartservice). You can specify which channels (e.g., Slack, PagerDuty) alerts should be sent to based on the labels of the SLO.
For detailed steps on setting up notification policies, refer to the Grafana Notification Policies. documentation.
