What's this ? is a python script, it visualizes server's load averages from simple uptime result lines log file. And this script is a my study for pygooglechart and Google Chart API.

Note: If you really need to use this script, I'll have to tell you a my opinion. Change your server. Porbably, it's better way than using this.

Download / Installation

You can download from, and extract tar.gz.


How to use

usage: [options] file

  --version             show program's version number and exit
  -h, --help            show this help message and exit
  -d DIR, --directory=DIR
                        output DIR [default: ./]
  -t HOSTNAME, --target-host=HOSTNAME
                        target hostname (for title)

Typical case's configuration is here:

$ crontab -l
*/5 * * * * sh /home/ys/bin/
$ cat bin/
/usr/local/bin/wget -q -O - \
              >> /home/ys/monitor/`date +%Y%m%d`.log
/usr/local/bin/python /home/ys/monitor/ \
              -t \
              -d /home/ys/public_html/monitor/ \
                 /home/ys/monitor/`date +%Y%m%d`.log

And utgraph supports these uptime formats:

   7:40PM  up 8 days, 23:51, 2 users, load averages: 0.01, 0.01, 0.00
   7:45PM  up 8 days, 23:56, 2 users, load averages: 0.03, 0.01, 0.00
   7:50PM  up 9 days, 1 min, 2 users, load averages: 0.00, 0.00, 0.00


  23:45:01 up 2 days, 13:36,  2 users,  load average: 2.46, 2.15, 2.02
  23:50:02 up 2 days, 13:41,  2 users,  load average: 2.70, 2.35, 2.12
  23:55:01 up 2 days, 13:46,  2 users,  load average: 2.25, 2.52, 2.26

In the version 0.5, utgraph needs load average lines that the first char is blank (' '), but of course you can easily edit utgraph's parser.

If you hope to view some hosts in one page, you may write simple html file, includes these hosts cur.png links. The cur.png files are always symbolic linked to newest image file when utgraph runs. After all, you hope to monitor more than 2 hosts, you should use the -d option.

Q: Do you use this script?

A: Of course, Yes. Oh my Dreamhost!!
