Application instrumentation strategy by technology stack: Beyla eBPF as the default zero-code path for Simple and Medium apps; OpenTelemetry SDKs/agents (Java, NET, Go, Python, Node.js) for Complex apps requiring deeper traces and custom metrics; JMX Exporter, prometheus_client, and runtime-specific exporters where stack-appropriate. • ServiceNow ITOM integration — co-own the design and review of Grafana → ServiceNow Event Management (native inbound integration) flow: event allow-list governance ("deny by default"), enrichment, deduplication, AIOps correlation, automated incident creation with severity mapping and assignment group rules, CMDB CI attachment, and ServiceNow-as-master incident state.
