What is Application Flow monitoring?
Technological, organizational or cultural environments have evolved with the rise of microservices, containerized apps, different programming languages, dependencies. Monitoring products relying on logs or "trace profiling" cannot face production application increasing complexity and massive amount log or trace to analyze. Application architecture and code shifts over the different network hops and layers making it hard for DevOps and Production engineers to grasp at a precise and standardized application performance host visibility, especially in the case of ephemeral instances and underlying infrastructure.
Despite language, framework or application topology changes, the network layer remains the fundamental layer on which applications converge upon, regardless of an application's complexity and heterogeneous stack.
With this in mind, ServicePilot has designed a package to summarize Server Interface Flow statistics collected for a single interface, in order to identify any application activity or suspicious behavior on the specified server interface.
It allows to automatically:
- Monitor the Server System metrics
- Get detailed metrics for each interface
- Provide global host traffic
- Discover and monitor all your applications
As a result, the ServicePilot Server Interface AppFlow Trace package and its agent can be installed, providing site reliability engineers immediate automated APM value without any changes to production application code.
Server Interface Flow monitoring
The apptrace-appflow package, based on collection made by the ServicePilot Agent, gets aggregated statistics for network flows. The ServicePilot Agent can collect network flows.
Aggregated statistics are provided for each monitored interface: Conversations, Bytes In/Out, Packets In/Out. These are calculated by summing all of the received flow packets for an interface. Depending on the flow protocol used, these values will either be representative of the total traffic passed through the interface or only representative of the samples that the flow protocol takes from the interface.
The ServicePilot Agent summarizes the flow data received to keep only the top 10 flows (conversations between the same IP addresses and port numbers) by volume of data transferred per minute. These conversations details are stored in a specific collection "IP Flow" in order to provide advanced dashboards presenting the top consumers of bandwidth by host and application per interface monitored.
