If you're running Kernel 4.14+ you can get more advanced Linux memory usage metrics like Proportional Set Size (PSS), Unique Set Size (USS), proportional swap usage and others (see the documentation for what you can get from /proc/]įor me, it was important to have structured output so that I could more easily consume it for analysis. Procpath can also visualise RSS of the target process into an SVG out of the box like this: $ procpath plot -d tgt.sqlite -f tgt.svg -q rss -p $PID The top utility and most other monitors use perhaps 2 tor 3 of a systems CPU time. Continue finding memory leaks in the current allocation set.

Click the Summary button to check for Memory leak problems. Using a SQLite GUI can be a more convenient to explore and query the database (e.g. Merely using a monitoring tool alters the systems use of resources, including memory and CPU time. Intel® Inspector User Guide for Linux OS. $ sqlite3 tgt.sqlite 'SELECT ts, stat_rss * 4 rss_kib FROM record WHERE stat_pid = $PID' When you think it has recorded enough datapoints, Ctrl+C it and this will give you the recordings. By default it makes a recording per 10 seconds (for the target process, its ancestors and descendants).

In the simplest case you point it to the PID of interest and let it record its Procfs metrics including Resident Set Size (RSS). Yes, can achieve exactly this, a bit more with Procpath (author here). I want to monitor memory usage of a process, and I want this data to be logged.
