Merging two log files

Posted 11-14-2011 at 05:52 AM by zhjim

Today I needed to merge two log files in cronological together. Heres my way about.

copy the two files to one host. (scp file name@server:~userhome
get the hostname infront of each line. (sed -i s/^/hostname/g first_file; ...)
cat ./first_file ./second_file | sort -k 3 > ./new_log

-k in sort stands for key. In my turn the datetime was the third field.

Improvements:
Get some color into the diffrence hostsnames.

Script to create a modified xen domU

fi

CONF=$1
TARGET=$2
IMG=./new_strap

#HOSTNAME=$(grep "name" $CONF)

Posted 08-24-2009 at 04:54 AM by zhjim

For all of you who wonder why ab (a.k.a apachebenchmark) gives an error like this

Code:

SSL not compiled in; no https support

I finally found out how to enable ssl support in ab.

Here are two minimal configuration options for the httpd-2.2.13 from apache.org.

With working ssl-ab

Quote:

./configure --with-ssl --enable-ssl --with-mpm=prefork --prefix=/home/ase/non/install --with-mods-shared=most

Without working ssl-ab

Quote:

./configure --with-ssl
