New Relic service level management (SLM) is a tool that helps DevOps teams and SREs identify business-critical services and monitor their health with service level indicators (SLIs) and service level objectives (SLOs). This allows for proactive establishment of processes to speed up code writing, pushing to production, and identifying bugs or outages quickly. New Relic's error budget feature helps reduce alert fatigue by configuring SLOs to only alert when the burn rate is above one for a sustained period of time. Defining service level objectives (SLOs) defines the target level of reliability or performance for a service. Monitoring and measuring service metrics, using error budgets to drive prioritization, automating error budget calculations, regularly reviewing and adjusting SLOs and error budgets are best practices for implementing effective error budgeting as part of an SRE practice. By setting up alerts on SLI- and SLO-related performance degradations with New Relic, teams can detect incidents quickly and resolve them before they affect customers. Conducting thorough incident post-mortems helps in understanding the root causes of service level breaches and formulating more effective response strategies. Implementing service levels properly leads to better customer and business outcomes, improves the quality of life for SRE and DevOps teams by driving focus and reducing alert fatigue.
