Uptimed is an up time record daemon keeping track of the highest
up times the system ever had.
Uptimed has the ability to inform you of records and milestones
though syslog and e-mail, and comes with a console front end to
parse the records, which can also easily be used to show your
records on your Web page
sudo yum install uptimed
Once installed, you will have to first create the boot id with this command:
After you have done that, you can see the boot records with the following commands:
# Uptime | System Boot up
-> 1 0 days, 00:37:05 | Linux 3.3.0-4.fc16.i686 Sun Apr 1 12:30:32 2012
NewRec 0 days, 00:37:04 | since Sun Apr 1 12:30:32 2012
up 0 days, 00:37:05 | since Sun Apr 1 12:30:32 2012
down 0 days, 00:00:00 | since Sun Apr 1 12:30:32 2012
%up 100.000 | since Sun Apr 1 12:30:32 2012
And if you want to see the same on you web-server then just copy the uprecords binary to your cgi-bin direcotry and you are done.
Here is a short description of pigz:
pigz, which stands for parallel implementation of gzip,
is a fully functional replacement for gzip that exploits
multiple processors and multiple cores to the hilt when compressing data.
And for the installation:
sudo yum install pigz
With pigz, if you don’t have many things running on your multi processor machine then you will see a significant improvement when you are gzipping the files.
