Depending on the context, SleepyGraph (or Sleep Graph) refers to a few different tools across software development, system administration, and health tech: 1. Developer Tool: SleepyGraph (VerySleepy Visualizer)
SleepyGraph is a callgraph visualization tool specifically designed for the VerySleepy profiler.
The Purpose: VerySleepy is a popular, open-source CPU sampling profiler for Windows C/C++ applications. SleepyGraph takes the raw data from that profiler and turns it into an easy-to-read, graphical call tree so you can spot code bottlenecks instantly.
The Tech: It is written in Python but functions as a multiplatform tool. Its installer bundles all necessary dependencies so Windows developers can use it out of the box. 2. Linux System Tool: Sleepgraph (Intel pm-graph)
If you are troubleshooting operating system performance, sleepgraph.py is part of Intel’s pm-graph suite on GitHub.
The Purpose: It is a command-line utility used by Linux kernel and system developers to visualize suspend and resume times.
The Output: It tracks every device driver and system process as the computer goes to sleep and wakes back up, rendering an HTML timeline graph. This reveals exactly which hardware driver or background service is slowing down your device’s wake or sleep cycle. 3. Consumer Tech: The Sleep Graph Apps
If you are looking at a mobile device, The Sleep Graph is a simple mobile application found on platforms like the Google Play Store.
The Purpose: It functions as a lightweight tracker where users log their sleep hours to get visual charts and analytics regarding their rest patterns.
(Note: If you are looking to analyze medical CPAP data for sleep apnea, you might actually be thinking of SleepyHead, a famous open-source tool used to graph breathing data, which has since been superseded by the community-led OSCAR software project.)
Which of these versions of SleepyGraph were you hoping to learn more about? I can provide installation steps or usage examples depending on what you are building or tracking. SleepyGraph homepage
