I have a list of files I need to copy on a Linux system - each file ranges from 10 to 100GB in size.
I only want to copy to the local filesystem. Is there a way to do this in parallel - with multiple processes each responsible for copying a file - in a simple manner?
I can easily write a multithreaded program to do this, but I'm interested in finding out if there's a low level Linux method for doing this.
I've got a general query regarding the location of the hosts file on Windows. It resides at this location:
f:\windows\system32\drivers\etc\hosts
My question is why? Could Microsoft have picked a more obscure location for a hosts file?
I'm trying to push disk io statistics from collectl V3.3.5-4 (with the multicast and socket Perl modules installed) through to a Ganglia version 3.0.7 instance.
Configured and followed the instructions here:
http://collectl.sourceforge.net/Export.html
but it doesn't appear to work.. it generates the stats to console, but I can't see these in gmond's output... calling via:
collectl -sd --export gexpr,127.0.0.1:8649,d=9
Does anybody have any ideas on how to fix this?
I'm looking to monitor performance on my Linux servers (which happen to be Centos). What are the best tools for monitoring things in realtime such as:
Looking for low level tools, rather than web based tools such as Nagios, Ganglia etc...
n.b. I'd like to know exactly what each tool does rather than just having a list of random toolnames if possible please. Why the tool is a better option than others would be good also.
