AppView

AppView is an open source, runtime-agnostic instrumentation utility for any Linux command or application. It helps users to explore, understand, and gain visibility with no code modification.

AppView provides the fine-grained observability of a proxy/service mesh, without the latency of a sidecar. It emits APM-like metric and event data, in open formats, to existing log and metric tools.

It’s like strace meets tcpdump – but with consumable output for events like file access, DNS, and network activity, and StatsD-style metrics for applications. AppView can also look inside encrypted payloads, offering WAF-like visibility without proxying traffic.

Features

• Generate metrics on process and application performance.
• Generate events, reporting on network, file, logs, console messages and http/s activity.
• Capture (decrypted) payload data without the need for keys.
• Generate a stack trace, and a core dump when an application crashes.
• Generate network flow information.
• Create a report on unique file and network activity.
• Install AppView in a Kubernetes cluster.
• Secure file and network access in an application.
• Instrument both static and dynamic executables.
• Attach to processes while they are running or start when the process does.
• Normalize and forward metrics and events, in real time, to remote systems.
• Summarize metrics and detect protocols.
