• Performance monitoring on Linux/Unix

  - by ervingsb

  I run a few Windows servers and (Debian and Ubuntu) Linux and AIX servers. I would like to continously monitor performance on these systems in order to easily identify bottlenecks as well as to have an overview of the general activity on the servers. On Windows, I use Windows Performance Monitor (perfmon) for this. I set up these counters: For bottlenecks: Processor utilization : System\Processor Queue Length Memory utilization : Memory\Pages Input/Sec Disk Utilization : PhysicalDisk\Current Disk Queue Length\driveletter Network problems: Network Interface\Output Queue Length\nic name For general activity: Processor utilization : Processor\% Processor Time_Total Memory utilization : Process\Working Set_Total (or per specific process) Memory utilization : Memory\Available MBytes Disk Utilization : PhysicalDisk\Bytes/sec_Total (or per process) Network Utilization : Network Interface\Bytes Total/Sec\nic name (More information on the choice of these counters on: http://itcookbook.net/blog/windows-perfmon-top-ten-counters ) This works really well. It allows me to look in one place and identify most common bottlenecks. So my question is, how can I do something equivalent (or just very similar) on Linux servers? I have looked a bit on nmon (http://www.ibm.com/developerworks/aix/library/au-analyze_aix/) which is a free performance monitoring tool developed for AIX but also availble for Linux. However, I am not sure if nmon allows me to set up the above counters. Maybe it is because Linux and AIX does not allow monitoring these exact same measures. Is so, which ones should I choose and why? If nmon is not the tool to use for this, then what do you recommend?

• Windows: How to add batch-script action to Right Click menu

  - by ervingsb

  I have a few programs that creates temp files or backup files or similar files that are not important. For example, GVim for Windows by default creates a backup file in filename.txt~. I sometimes need to clean up a dir and remove all these files. I have made a simple .bat file for this. However, it is cumbersome to have to start up cmd, navigate to the folder, run the script. Especially since this is a script that I would like to run often on various folders. And I do not want to copy the script to multiple folders, as this would be a maintenance nightmare. So, I was thinking, that the best solution would be to add a Right Click menu item that allows me to run the script. So that I can right click on a folder in Explorer and click Cleanup and then have my script run on this folder. So my question is: How do I add a right click menu action that runs a custom batch script?
