+# Valgrind
+
+The [Valgrind](https://valgrind.org/) tool suite provides a number of debugging and profiling tools that help you make your programs faster and more correct. The most popular and the default of these tools is called **Memcheck**. It can detect many memory-related errors that can lead to crashes and unpredictable behaviour.
+
+# Run memory management detection
+
+``` bash
+valgrind --leak-check=full --show-leak-kinds=all --log-file=%p.log --trace-children=yes --track-origins=yes --read-var-info=yes ./pgagroal -c pgagroal.conf -a pgagroal_hba.conf
+```
+
+# Generate valgrind report with suppressed rules
+
+``` bash
+valgrind --suppressions=../../contrib/valgrind/pgagroal.supp --leak-check=full --show-leak-kinds=all --log-file=%p.log --trace-children=yes --track-origins=yes --read-var-info=yes ./pgagroal -c pgagroal.conf -a pgagroal_hba.conf
+```
