what timeframe is used?


thanks.

What doubts do you have about this?

As far as I know, the value displayed = the value at the last check, so it is not the avg. across the selected timeframe but the most recent actual value. Memory health displays memory used by processes, excluding RAM used by system caches and buffers.

Hello

Host pages include two memory-related metrics for your hosts, Memory used and Page faults. Both measurements and other factors, are used to correlate and calculate host high memory incidents.

  • Memory used
    Percentage of total RAM used by processes. RAM used by system caches and buffers isn't included in this metric. Dynatrace calculates memory usage as:
    memory_used = total_memory_size - (free_memory + active_memory + inactive_memory + reclaimamble_memory)

for your picture, the value of memory depends on the selected time period
