Procweb is a process that can be run to monitor another process. Procweb runs and samples the process periodically retrieving these values:

• State;
• CPU usage;
• Resident set size;
• Virtual memory size;
• Total main memory;
• Total read from disk;
• Total written to disk;
• Total read;
• Total written;
• Niceness;
• Number of threads;
• Uptime;
• Start time.

Some of these values can be used to draw a chart. Procweb provides a web interface to display data.

Procweb can be used to monitor a process for memory leaks or unexpected behavior during many hours or days of work.

NOTE: the version in the root of the repo is based on Qt. At the moment, I'm focusing more on the Rust version, which can be found in the procweb-rust directory in this repo.

Procweb is a C++ process that can be run in background. It depends on Qt >= 6.4. The process provides a web interface written in TypeScript with Angular which represents data in time. Procweb stores samples without expiration, so it is possible to inspect old data. The web interface can be accessed at http://<ip_addr>:3000.

Procweb includes a AppImage that can be run, without having to install any dependency. At the moment it only works on x64.

Here is an example of how procweb can monitor data and present it through the browser.

The project includes two modules: one is the angular webapp, the other is the Qt process running as a server and sampling the process. First, you'll need to build the angular application. The angular app is then embedded into the procweb executable:

cd procweb-webui
./build.sh

then you'll be able to build the Qt binary:

mkdir build
cd build
cmake ..
make
