![]() (gdb) break 6 Breakpoint 1 at 0x117e: file memleak.c, line 6. ![]() To set the breakpoint, use the break command: bash. rootsrv: free -m total used free shared buff/cache available Mem: 1981 720 319. Theres probably some clever way to filter on ppid with the. If you want something scriptable, theres something a bit like the below - although its not doing quite what youve asked for (PPID 1), but you can group based on e.g. In this example, lets assume the malloc call is at line 8. You can use the command free to find the current memory usage in the server. atop - launch it and press m (memory usage) and p (group by process name). The resources tab displays last 60 seconds of data in three different graphs for CPU, Memory and Network. Set a breakpoint at the line where the memory allocation occurs, which is the malloc call. vmstat considers a single kilobyte equal to 1024 bytes. In the default operation, vmstat displays memory statistics in kilobytes. To stop the vmstat process, send the break character (C or Control+C) as above. The file systems tab displays the disk usages.įig: Ubuntu System Monitor – File Systems tab You may choose to direct this output to a file for logging instead of leaving it running endlessly in a background terminal session. To view the system monitor in a bigger window, right click on any one of the system monitor graphs in the task bar, and click on “Open System Monitor”, which will display the System monitor in the bigger window as shown below.įrom the Processes tab, you can view all the process along with their status, %CPU usage, memory used by the process etc., You can also kill a process directly from here.įig: Ubuntu System Monitor – Processes tab For Unix based systems (Linux, Mac OS X, Solaris), you can use the getrusage() function from the standard library module resource.The resulting object has the attribute rumaxrss, which gives the peak memory usage for the calling process: > resource.getrusage(resource.RUSAGESELF). You can change the colors, and the refresh interval.Īfter the above selection, you’ll see 4 graphs in the Ubuntu task bar itself as shown below.įig: Multiple graphs displayed on the Ubuntu task bar Ubuntu System Monitor GUI ![]() You can also choose Network, or Swap Space if you like to monitor those.īy default it displays the memory usage in green, cache in light green, process usage in blue, load average in red. One extremely easy way to see what processes are using the most memory is to start top and then press shift+m to switch the order of. Select the following check-boxes under the ‘Monitored Resources’ section. One of the best commands for looking at memory usage is top. Right mouse click on the Processes graph that is displayed on the task bar panel, and select ‘Preferences’. It seems that the memorygetusage() always returns 2mb (in bytes). It can perform overall checks for total CPU and memory usage or it can focus on important processes that you select and report only on those. Fig: Processes Usage Graph on Ubuntu Task Bar Panel Add Memory Usage, Load Average and Disk Usage Graphs to Ubuntu Task Bar Panel hi, yes, I tried both memorygetusage and memorygetpeakusage on a script that created a string and looped 50 times increasing the string each time.
