![]() ![]() ![]() The perf mem command provides information about memory latency, types of memory accesses, functions causing cache hits and misses, and, by recording the data symbol, the memory locations where these hits and misses. On the NI Linux Real-Time OS, you can also get helpful information about memory usage on the Real-Time target by opening /proc/meminfo directly from the target. The mem subcommand of the perf tool enables the sampling of memory accesses (loads and stores). ![]() In the simplest case you point it to the PID of interest and let it record its Procfs metrics including Resident Set Size (RSS). Does such a tool exist Yes, can achieve exactly this, a bit more with Procpath (author here). When we deploy a real-time application written using the LabVIEW Real-Time Module, we expect the LabVIEW process to use the largest amount of memory. I want to monitor memory usage of a process, and I want this data to be logged. To get an accurate account of memory usage, we can look at the process on the device that uses the most memory. It provides an interactive as well as real-time monitoring of the system performance. btop is a handy resource monitor fully interactive with a beautiful UI helping you manage the Linux servers. It can be difficult to get a simple accounting of system memory usage due to how memory management and reporting is handled by the Linux OS.However, we can use the tools provided by the Linux OS to accurately monitor the memory usage on the real-time device. Linux SAR (System Activity Reporter) is a powerful system monitoring tool that helps administrators to monitor performance metrics such as CPU, memory, I/O, network, interrupts, and many more. Memory management and reporting on Linux devices differs significantly from targets running operating systems such as Windows or VxWorks. Additional InformationOn NI Linux Real-Time OS targets, the Free Physical Memory Property Node of the System Configuration API along with the Distributed System Manager fail to give an accurate accounting of the free physical memory on the device.
