Hello,
I got very good feedbacks on the reports. Thank you for these ! Now, I'm going to explain how it works. You got two parts. On one hand, some shell scripts will generate the rrd graphs and save them as PNG. In other hand, a php page will do the reports with the (GREAT) help of the libfpdf.
Before I go further, I want to say that I created a directory called 'pdf' into @HOBBITSERVERHOME/www/ In addition, I make an 'images', 'graphrrd', 'export' directories. In conclusion, I got the 'pdf' directory organized like this :
[hobbit at psi200 pdf]$ ls -al total 164 drwxr-xr-x 6 hobbit hobbit 4096 mai 2 14:52 . drwxr-xr-x 30 hobbit hobbit 4096 mai 2 15:25 .. drwxr-xr-x 5 hobbit hobbit 4096 avr 30 23:59 export drwxrwxr-x 157 hobbit hobbit 4096 avr 28 19:20 graphrrd drwxrwxr-x 2 hobbit hobbit 4096 mar 22 18:31 images -rwxrwxr-x 1 hobbit hobbit 5251 mar 22 15:52 pdf.php -rwxrwxr-x 1 hobbit hobbit 52241 avr 21 19:53 rapport.php -rwxrwxr-x 1 hobbit hobbit 11125 avr 11 16:17 rapportredac.php -rwxrwxr-x 1 hobbit hobbit 7459 avr 10 15:31 rapports_annuels.php -rwxrwxr-x 1 hobbit hobbit 8814 avr 10 15:30 rapports_mensuels.php drwxrwxr-x 2 hobbit hobbit 4096 mai 2 12:34 scripts
export : directory where all reports generated automatically go. graphrrd : directory where all PNG graphs generated automatically go. images : directory where all images to include in the pdf go. I'm giving you some images in images.zip scripts : directory to stock scripts which generate the PNG graphs.
Ok, let's go !
- first part : shell scripts (rrdscripts.zip). Decompress the scripts into your 'pdf' directory and edit them to modify the destination of PNGs graphs. Once done, launch master.sh and look at the results. For one server, you must have 4 graphs BY test. Actually, I'm graphing 6 tests - cputil, load, memory, iowait, network (don't work for linux at the moment !!) and run-queue. You can add more tests if you want ! For example, you will have :
graphrrd/myserver/ load.myserver-[day/week/month/year].png mem.myserver-[day/week/month/year].png ...
Now, you can do a cron to launch master.sh every hour to update your graphs. Thanks to ED (ed.zehome.com) for his site and his explanation of rrdtool. I used examples from his site into the scripts...
- Second part, the php pages (pdfreports.zip). Put these files directly into the pdf directory. You have five files :
pdf.php --> contains the main form with hobbit's look ! You may add this page to your hobbit's menu. Simply type in the text field a server name and got your *beautiful* report :)
rapport.php --> contains all the php code. So, the file pdf.php calls this file when a name is submitted. Within this script you can define
rapportredac.php --> contains a form with several textareas. You have to put a server name, check a box if the server is overloaded, underloaded or 'normally loaded'. Then, all text in the textareas will go under graphs in the pdf report. You can easily build analysis for your boss or team... Like pdf.php, this page calls rapport.php.
rapports_mensuels (monthly) and rapports_annuels (annual - sorry for french) : you can execute these scripts to have reports - for all servers
automatically generated and put into a directory. Like 'master.sh' you can do a cron to have reports each end of month. These two scripts even check the last day of month and send a mail when reports are generated.
If all is correct you will have a pdf report with your graphs in it when you click on 'rapport !' on the pdf.php page. That's all ! You have to edit them by hand to modify and adapt to your configuration. I'm sorry the code isn't very clean at all ! Moreover, you will have a lot of french text in the files. I'm beginning to rewrite comments into english. Feel free to make comments and/or modifications to the scripts.
I hope, these reports will satisfy your needs. I'm sorry for the shorts explanations but I got another project which take all my time... So, I will try my best to answer questions, if you have some ! Best regards,
Thomas Seglard
