  • Dynamic collect Stdout when running with containerized environment
• Traces
  • OpenTelemetry protocol

  • Skywalking V3 protocol
  • ...
• Metrics
  • Node metrics
  • Process metrics
  • Gpu metrics
  • Nginx metrics
  • Support fetch prometheus metrics
  • Support transfer telegraf metrics
  • ...

For the complexity of C++ dependencies, the compilation of LoongCollector requires you have docker and golang installed. If you aim to build LoongCollector from sources, you can go ahead and start with the following commands.

make
cp -r example_config/quick_start/* output
cd output
./loongcollector
# Now, LoongCollector is collecting data from output/simple.log,
# and outputing the result to stdout.
