In order to see what process was busy in the previous period. ![]() Osquery won’t be able to give you a percentage for a given moment in time as in order to do this you’d have to continually poll the processes table and compare the last snapshot to the most recent snapshot. You can also figure out what processes are eating away at your valuable CPU time. This will yield: +-+-+-+ | pid | username | name | +-+-+-+ | 28527 | hugh | Google Chrome Helper | | 28526 | hugh | Google Chrome Helper | | 28512 | hugh | syncdefaultsd | | 28476 | hugh | Google Chrome Helper | | 28470 | hugh | osqueryd | +-+-+-+ Most CPU intensive processes since boot SELECT pid, username, name FROM processes p JOIN users u ON u.uid = p.uid ORDER BY start_time DESC LIMIT 5 For example, we can fetch the username, instead of the uid for a given process. ![]() +-+-+-+ | pid | uid | name | +-+-+-+ | 28508 | 501 | syncdefaultsd | | 28501 | 501 | Google Chrome Helper | | 28476 | 501 | Google Chrome Helper | | 28470 | 501 | osqueryd | | 28458 | 501 | Google Chrome Helper | +-+-+-+ Processes with usernamesĪs Osquery provides an SQLite interface you can also join additional tables to enrich results. The command above will retrieve the first 5 most recently executed processes, returning just the process id ( pid), user id ( uid) and the process name ( name). SELECT pid, name FROM processes ORDER BY start_time DESC LIMIT 5 To enter the interactive Osquery terminal. For this, Osquery provides the process_events table which we’ll touch on later. It doesn't provide historical information about all the processes that have run since the system booted. It’s important to note that the processes table only provides a point in time snapshot of the processes currently running on the system. Of Osquery’s 250+ “virtual tables” the processes table provides a virtual interface into your systems currently running processes.
