# Step 2: Runtime Information

> It is useful to examine eXtremeDB runtime information as demonstrated in SDK sample `samples/native/core/01_rtconfig_inmem`. Please build and run this sample and note the information displayed. In the source file main.c notice that a number of “sample helper” functions are called. In addition to `sample_os_initialize()`, `sample_pause_end()` and `sample_os_shutdown()` introduced in step 1, the functions `sample_header()` is used to display a heading message and `sample_show_runtime_info()` is called to display runtime information.

> These helper functions are implemented in file `common.c` and encapsulate many standard operations, allowing simplification of the sample application code to illustrate only the points of interest. Here it is instructive to examine function `sample_show_runtime_info()` to see how runtime information is retrieved from the `mco_runtime_info_t` structure returned by calling the static API function `mco_get_runtime_info()`.
