I later gained a CompSci Degree and continued programming, moving into databases (DBA) and I've spent the last 10 years to present day as a Unix Sys Admin. I spent the last couple of years writing java for a ...
Are there any libraries that would allow me to call a JMX MBean method from a shell script. We expose some operations/admin commands through JMX, and we could have our admins use JConsole, or VisualVM, but some tasks are better left to automation. In that automation we'd like to be able to call a JMX MBean method on our running server, p...
When watching a growing log file with e.g. "less -iS +F service.log" I want to limit the display to lines matching a certain pattern. I tried something like less +F service.log | grep <pattern> | less +F which doesn't work. Also cat < service.log | grep <pattern> | less +F doesn't do what I want. It looks like the input is already...

Apache has been the de facto standard web server for over a decade, but recent years have brought us web servers that consume less RAM and handle many more requests per second using fewer threads and asynchronous i/o. In my opinion, I also find the configuration of these servers to be more straightforward and minimal. Why do people use ...

Lately the box has seemed really slow. The only kind of discovery i could think of doing was looking in the task manager, where i can see w3wp and sq...

Hello everyone, i have a few processes that have to be run at high priority (chrt 98) that will occasionally decide to hard-lock and peg 1 core at 100% (not a huge deal) but more importantly it will use all the IO on a system, so much that its impossible to log into the machine via ssh to kill it or perform any task on the machine that i...
