Monitoring CPU time
Hi, I'm currently playing with munin http://munin-monitoring.org/ and I would like to monitor the CPU usage on DragonFly hosts. The FreeBSD plugin uses the sysctl kern.cp_time, which is not present on DragonFly. Is there any way to easily get the different percentages of nice, idle, user, system, etc... time from a shell ?

how to switch the base compiler to gcc 4.4.2
Hi: How does one switch the base compiler to gcc 4.4.2 ? Here is some info for my setup: . running DragonFly 2.7-DEVELOPMENT v2.7.0.47.g3f16d (HEAD as of April 4, 2010). . the HEAD was built with CCVER=gcc44 for - buildworld - buildkernel - installkernel - installworld - upgrade . /usr/libexec/gcc44 directory has CC c++ c++filt cc cc1obj cc1plus cpp g++ gcc gcov . have setup the following entries in /etc/make.conf CCVER=gcc44 CC=gcc44 CXX=g++44 CPP=cpp44 CFLAGS+=-mssse3 i donot see any /etc/libmap.conf (as seen in FreeBSD) which needs to be tweaked for rtld and ldd. Any pointers as to how to make gcc 4.4.2 as the base compiler for my custom DragonFlyBSD system on AMD64 box ? -- thanks Saifi.
Laptop still doesn't boot with ACPI

2.6 release status update
The ISOs and IMGs for 2.6 will be built and uploaded this afternoon, and made available to release users. The official announcement is being held pending the i386 bulk package build finishing. It should finish today but we still need to give the mirrors a day or two to get the packages before we announce. The x86_64 bulk build finished and is on avalon already.

there might be a better way to do this - but you can snag that
particular set of data from vmstat -c 1 ..
Thanks for the tip, it's almost what I want.
FreeBSD:
$ sysctl kern.cp_time
kern.cp_time: 1797279 579339 1349174 128959 811149589
DragonFly:
$ vmstat -c 1 | tail -n 1 | awk '{ print $14,$15,$16 }'
675875492 705365686 1527141678
Unfortunately, there's no data for nice or interrupt. Time to dig into top
sources...

It has been quite a slog but we're on the final lap! Technically, we're OK now - the 2.6 build of pkgsrc-2009Q4 packages is already done, from df.v12.su: http://avalon.dragonflybsd.org/packages/i386/DragonFly-2.6/pkgsrc-2009Q4/All/ Since pkgsrc-2009Q4 for 2.4.1 was already built on that machine before the 2.6 update, any of the packages that were unchanged were fine, so it was able to go with those. They'll cause the annoying warning: built on DragonFly version X even though you are on DragonFly version Y warning, but they should be just fine; we didn't do anything to break binary compatibility between 2.4 and 2.6 as I recall.
Source IP
Hi, I'm getting log messages which say that login failures are from a specific URL rather than an IP, I tried running ftpd with the -h option but it didn't fix this... So, can anyone tell me how I can make ftpd always give me the IP rather than, sometimes, the URL? Alternatively, can someone point me to C code which will allow me to convert a URL to an IP? Thanks, Walter
