op5 AB is a world leading OSM – Open Source Management – company that delivers software based on open source for control of IT systems and networks. The award winning op5 Monitor is now released with important enhancements that will enable customers and other vendors to further improve usability and integration for optimized IT monitoring.
op5 Monitor is based on Nagios*, the industry standard for enterprise-class IT infrastructure monitoring. Until now, op5 Monitor has had to rely on the basics of standard Nagios Graphical User Interface (GUI) for presentation and overall user experience. With the release of op5 Monitor 4.2 we include a fully functional preview of a brand new GUI, now based on the Ninja Open Source project. The new GUI is based on a modern PHP architecture and is now shipped for real operation testing. Read the rest of this entry »

At 4.30 CET I lost my internet connection and 9.30 CET it was back. After that it was flapping up and down for a couple of hours. My ISP is Bredbandsbolaget and I continusly looked at their so called maintenance site. Not a word about the disturbance. It really annoys me that there was no information what so ever, I tried to call them and gave up after 20 minutes of "thanks for your patience" in my ear. I tried to send an email and got an automated answer saying that they will come back to me in a couple of days. Yes days!!
I know for sure that the problems was not on my side, because a friends friend that lives in the same area had the same problem.
This graph shows the packet lost when pinging the closest router:
I noticed that my blog become slower and slower by using op5 Monitor and webinject, see previous article. From installation 2.5 seconds to over 7.5 seconds to run my testcases. The most annoying was that the it was a very linear increase see graphs below. My first try was to tune MySQL
By installing wp-cache the testcase went down to 0.4 seconds.
The drawback is that my counter widget is getting updated every hour instead of every reload of the webpage.
Take a peak at some nice graphs showing that I stopped the increasing loading time and got a speedup from 7.5 seconds to 0.4 seconds:

Op5 has written an excellent article howto monitor Esx3.x, ESXi, vSphere 4 and vCenter Server with op5 Monitor. This article is op5 Monitor centric but op5 Monitor is based on Nagios so this article can be used to implement Nagios vmware monitoring.
The plugin used to gather the information is GPLd and developed by op5.

Background
This article is describing best practice I have collected after a 10 year period with Systems- and Network management. My role has varied between consultant, trainer, systems engineer, project manager and architect.
Very many programs creates log files. They are great for trouble shooting and in some cases the only place to find out if there is something wrong.
A monitor friendly software has a way of figuring out the status this very moment by providing relevant information via for example: SNMP, a web page, status stored in a database, a well documented API available in several different languages or similiar.
A NON monitor friendly application has for an example a javascript webpage where all the status can be read, unfortunatly this becomes more and more common.
When someone writes a piece of software, think about that someone else might want to know the status of it.

Background
As a former Novell employee there is one software I really miss and that is iFolder. It is an excellent file syncronization software. You configure iFolder where your local iFolder files are located and what server to syncronize against. Do a sync and now they are avilable at any iFolder instance if you sync against the same server. It works almost magical. You can have several machines where you create files, sync them. After that go to a fresh machine do a iFolder sync and volá there is the files.
According to Novell iFolder is OpenSourced but the installation is horrible on any other plattform then SuSE.
Solution
After some investigation I finally stumbled on Unison. Unison works on Unix like operating system like, Linux, BSD, OS X and also on Windows. It is in the Ubuntu repository and RHEL rpm package can be found here.
Simple example
Syncronize one directory testunison containing two files
peter@peter-laptop:~$ unison -ui text -contactquietly testunison ssh://zelda/testunison
peter@zelda's password:

Links
I have moved my blog from one system to another and at the same time upgrade to the latest and greatest WordPress version. Using the default link structure in WordPress gives links like: http://www.it-slav.net/blogs/?p=115 when a more logical link name is: http://www.it-slav.net/blogs/2008/11/17/op5-monitor-or-nagios-plugins-for-1-wire-temperature-measurement/
The more logical name gives date and title of the blog post instead of a cryptic number. Changing from one to another is rather simple, just change it in the wordpress settings, but there is several drawbacks:
- Referers stop working, if someone is refering to your pages they will stop working until someone updates the link
- Search engines will refer to the wrong page until the pages are indexed again and very likely the rank will drop
- WordPress internal references will stop working, so the mainpage links will stop working. This is real stupid and I do not understand why WordPress behaves like this.
The solution is to install the plugin "Permalinks Moved Permanently" which fixes this problem, make sure that the webserver allows rewrite.
