Which SLIs/SLOs are relevant for Custom Resource Definitions?

Monitoring Custom Resource Definitions (CRDs) in Kubernetes is crucial for ensuring that the custom resources behave as expected and to guarantee the reliability of applications that depend on them. Key SLIs (Service Level Indicators) and SLOs (Service Level Objectives) can help in maintaining the health of CRDs.

        // Example of SLIs and SLOs for Custom Resource Definitions
        $SLIs = [
            'availability' => '90%', // percentage of time the CRD is available
            'latency' => '200ms', // acceptable response time for CRD operations
            'errorRate' => '1%', // maximum acceptable error rate for CRD requests
        ];

        $SLOs = [
            'availabilitySLO' => '95% of time the CRD's status is ready',
            'latencySLO' => '95% of operations respond under 100ms',
            'errorRateSLO' => '2% of operations can fail without hitting alert threshold',
        ];

        function checkSLOs($SLIs, $SLOs) {
            foreach ($SLIs as $key => $value) {
                if ($value < $SLOs[$key . 'SLO']) {
                    echo "SLO breached for {$key}";
                }
            }
        }

        checkSLOs($SLIs, $SLOs);
