That’s fine, the RES column in top says the same if you sum up all values for a process (attention: the values in top’s RES column are KB by default), and compare process memory to total physical system memory. Troubleshooting This checks sometimes reports > 100% memory usage total - free does not necessarily match used. Used: Memory used, calculated differently depending on the platform and designed for informational purposes only. Total: Total physical memory (exclusive swap). Shared (Linux, BSD): memory that may be simultaneously accessed by multiple processes. total - used does not necessarily match free. This is calculated by summing different memory values depending on the platform and it is supposed to be used to monitor actual memory usage in a cross platform fashion.īuffers (Linux, BSD): Cache for things like file system metadata.Ĭached (Linux, BSD): Cache for various things.įree: Memory not being used at all (zeroed) that is readily available note that this doesn’t reflect the actual memory available (use available instead). WARN or CRIT if total memory usage is above a given threshold.Īvailable: The memory that can be given instantly to processes without the system going into swap.
