# How to check process memory consumption
You can use 'ps' command to check the virtual and physic memory used by all processes with the correct arguments.
```
$ ps -eo pid,tid,class,rtprio,stat,vsz,rss,comm
```
This shows the list of processes and the virtual (vsz) and real memory (rss) consumption, among other info.
You also can filter this with 'grep', and if you want to monitorize the size in time, use 'watch' to refresh the information periodically.
```
$ watch -n 0.5 'ps -eo pid,tid,class,rtprio,stat,vsz,rss,comm | grep app_name'
```
