Dynatrace provides detailed insights into host-level resource usage, focusing on CPU, memory, network, and disk metrics to assess the health of monitored hosts and assist in root cause analysis of issues. The introduction of the 'Reclaimable memory' metric, available with OneAgent version 1.159 and Dynatrace version 1.160, enhances memory utilization tracking by categorizing memory into used, free, and reclaimable, which is particularly relevant for virtual machines where memory ballooning is common. This metric helps in understanding actual memory use by considering system caches and processes, offering a more accurate depiction than traditional system tools like Linux's 'free' command. By updating its memory usage charts, Dynatrace allows users to better manage resources, especially in cloud environments where physical hosts are less common. This new approach aims to provide a comprehensive view of memory allocation, facilitating better resource management and problem resolution.
