+description: Setting Up System Logging
+---
+
+ManapiHttp provides 5 levels of system logging:
+
+- **```LOG_TRACE_NONE```**  
+  No debug output
+
+- **```LOG_TRACE_HIGH```**  
+  Only critical messages will be printed
+
+- **```LOG_TRACE_MEDIUM```**  
+  Some less important messages will also be printed
+
+- **```LOG_TRACE_LOW```**  
+  Almost all messages will be printed
+
+- **```LOG_TRACE_HARD```**  
+  All debug messages will be printed, including messages from TimerLoop, EventLoop, TCP and UDP
+
+<Callout title="Note">
+In release mode, messages with the ```LOG_TRACE_HARD``` level are removed.
+</Callout>
+
+```cpp
+#include <manapihttp/ManapiInitTools.hpp> // manapi::init_tools::log_trace_init
+#include <manapihttp/ManapiDebug.hpp> // manapi_log_trace
+
+int main(int argc, char *argv[]) {
+    // System log initialization (not thread-safe)
+    manapi::init_tools::log_trace_init(manapi::debug::LOG_TRACE_HIGH);
+    // Print message (method is blocking and thread-safe)
+    manapi_log_trace(manapi::debug::LOG_TRACE_HIGH, "Application has started!");
