Splunk AppDynamics, formerly Cisco AppDynamics, is APM sold per host or CPU as SaaS or on premises; pages here cover replacing it with OpenTelemetry and self-hosted SigNoz or Grafana and Prometheus.
Comparing AppDynamics APM, with business transactions and agent-based discovery, against self-hosted SigNoz with OpenTelemetry traces, metrics and logs: what maps across, what needs custom work, licensing and the effort of running each.
For teams that want to replace AppDynamics with a composable open-source stack: Prometheus for metrics, Grafana for dashboards and alerting, and an OpenTelemetry trace backend, compared with AppDynamics on coverage, effort and cost structure.
Moving off AppDynamics agents: using hybrid mode or the Collector to send OpenTelemetry traces to both backends, replacing agents service by service, rebuilding health rules as alerts and dashboards, and the business transaction views that need a new approach.
Cost of ownership by component: AppDynamics editions per host or vCPU and add-ons for security, RUM, synthetics and SAP, against self-hosted SigNoz or Grafana with Prometheus, storage, migration effort and the team that operates it.
On-premises AppDynamics Controllers reach end of maintenance on a rolling schedule, with 25.7 ending October 31, 2026. This page compares upgrading, moving to the Kubernetes-based Virtual Appliance, and replacing it with a self-hosted OpenTelemetry stack.
