[hobbit] PDF reporting [news] ! First part
by Mark.Deiss＠acs-inc.com 03 May '06

03 May '06

Cool. I wrote standalone scripts in similar vein to generate pdf reports for BS15000/ISO90000 capacity reports. The scripts generate the png graph files and then incorporates some html files to build the final pdf file using htmldoc software package (the non-commercial version). In our case, these are meant to be separate reports and are not linked into the hobbit web pages. One thing that is a bit vexying is configuring rrdtool commands to insert threshold lines and tailor the graph legends. The rrdtool command syntax (not hobbit) changes across releases so if anyone is fooling around in these areas, caveat emptor. I maintain multiple releases of rrdtool sets and go back and forth between the versions trying to get particular features. Generating legends that include not only the minimum and maximum graphed value, but also the last graphed value. Something that management likes to see. Also for the disk/filesystem utilization percentages, also including the allocated disk amount in gigabytes. Getting clean auto-formatting for the legends is a bear. -----Original Message----- From: thomas.seglard.enata at cnp.fr [mailto:thomas.seglard.enata at cnp.fr] Sent: Tuesday, May 02, 2006 11:21 AM To: hobbit at hswn.dk Subject: [hobbit] PDF reporting [news] ! First part 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 ! 1) 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... 2) 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 !

no purple backround page
by lehnert＠adtech.de 03 May '06

03 May '06

Hi, we are trying the latetst hobbit release on our test-system and it seems to work fine so far. The only problem we have, is that when a host gets "purple" because of a stoped service on that host, the background color does not change to purple, like the old BB did before. But this is a very important funktion for us. What can we do? many thanks, Pascal Lehnert

Changing the frequency of a specific test
by ian.marsh＠hants.gov.uk 03 May '06

03 May '06

We're currently experiencing a problem with httpd on one of our servers that isn't being caught by hobbit. Is it possible to specify a custom test interval for just one test on one server? The hope is that it'll stand a better chance of catching the problem if it runs, say, every minute rather than every 5 minutes.

TIME and localtime in hobbitd-alerts.cfg
by Dominique.Frise＠unil.ch 03 May '06

03 May '06

Hi, We have problem setting TIME in our rules. Example of a rule for excluding alerts for the ldap service between 05:00 and 05:30 AM: HOST=uldns1,uldns2 SERVICE=ldap TIME=*:0500:0530 In notifications.log we see: Wed May 3 03:02:40 2006 uldns1.ldap (1.2.3.4) 0797852006 1146625310 0 Wed May 3 03:02:40 2006 uldns2.ldap (1.2.3.4) mister.test at example.com 1146625360 0 This seems to indicate that Hobbit treats the TIME as GMT (2 hours shift because of summertime) but we use CEST on the server (TZ=Europe/Zurich) How can we solve this?

vmstat graph on Red Hat Linux release 9 graphing wrong data 8-(
by crlangfo＠ugs.com 02 May '06

02 May '06

All, I have several Red Hat Linux release 9 systems that I have to maintain that I am currently monitoring with hobbit. The vmstat graphs on my other linux system work perfectly but for some reason the Red Hat 9 systems are graphing the wrong columns of data. The graphs show the system cs data as user, cpu us as system and cpu sy as idle. Any ideas why the data is off by one column?????? What do I need to do to get hobbit to graph the right columns????

I am unable to fin dbb-hostedit on deadcat and googling finds some discussion about it, but I can't find where to download it. Is it still available? -----Original Message----- file is maintained mostly by the (non-unix-savvy) staff here, using the bb-hostedit CGI script, and I'd rather not have them have to keep track of which host needed which NET tag, etc.

I'm starting to look at setting up 'propr' monitoring for my production SAP environment, and wonder if anyone else is playing with HACMP clusters
by KauffmanT＠nibco.com 02 May '06

02 May '06

I need to split the monitoring for SAP and Oracle from the monitoring of the host it runs on -- because, in an IBM HACMP environment, the workload can move. So the oracle tests, *some* of the disk space tests, and *some* of the proc tests move from one box to another. So does the primary IP address. I need to be able to track 'colorado' the box (the hostname does NOT move) as well as 'colorado' the IP address. 'Colorado' the address could actually be pointing to the 'thames' or 'yukon' boxes. At which time, 'colorado' the box will be responding to the 'colorado-bt' adapter address (if 'colorado' the box is up at all). I can get some of what I want by running two clients, one for 'colorado' the box, and one for 'SAP' or some other such synthetic name. The biggest two challenges I see are splitting the OS filesystems from the application filesystems for freespace reporting, and the shifting IP address. I may have an 'out' on the IP address in the future, if I can migrate to what IBM calls 'aliasing' -- where they add the running address as a second address on the adapter and respond to both. And to make this a bit more fun, I have THREE of these silly environments to work with. Henrik, is there any way to hang two different IP addresses on the same bb-host entry such that the network connectivity test will be happy if either one responds? They are always on the same IP network, just different host addresses (our convention is to add 100 to the last octet to get the boot-time address for the matching run-time address). Is anyone else doing something silly like this?
