Quick note to let our users know that there was an XML tag closure error on the “alert_22″ subroutine in the “bin/kontroll-reporter-cli.pl” script. This does not affect the webapp portion of Kontrollbase – only reports generated via the command line reporter script. It is not a fatal error but will cause the XML file to [...]

I’ve been wanting to write a backup script for a while now that does the following: reads the partition information for the directory that you are backing up into and computes the used/available/percentage-available space. Then it reads the total data size from the MySQL tables and ensures that you have enough space on disk (for [...]

If you have been wondering why the overview and graphs pages say “no data to display” on the graphs when you first install Kontrollbase, it’s because there’s no data in the database being returned from the queries that generate the graphs – this is because a new install has no data to graph. This has [...]

If you’ve noticed that your recent upgrade did not go as planned and now the application does not load – please check this page: http://wiki.kontrollsoft.com/wiki/UpgradingReleases for notes on upgrades between versions. Typically you need to execute a SQL file against the current schema to bring it up to date. If you have any questions please [...]

I’m pleased to announce the first release of Kontrollcomm – “The Server Command Automation Interface” is a web-based application that automates remote command execution on linux and unix based servers. There are three main areas of the application: Hosts, Templates, and Commands. The use is very simple: all of your hosts are setup in the [...]

This is a small revision and will only be available through SVN. However, it is an important one to speak about as it solves a former issue when running the application on a screen smaller than 1024px wide. While most users may not have noticed this since they have larger monitors it has been noticed [...]

Just a quick bit of news to let you all know that additions to the standard Kontrollbase and Kontrollkit userguides are being halted while we migrate the documentation to a new wiki system run by the very nice Trac software.

Website health checks are a crucial service to an operations team.

If you have been reading the Kontrollbase performance reports and noticed that one alert says your connection usage vs max connections ration is too high but then recommends you to decrease the max_connections variable, then you will find this fix handy. Its two simple queries that execute on the Kontrollbase schema to update the max_connections [...]

Thomas Brenneke contacted me to discuss his interest in utilizing the [...]

The time has come for major performance improvements to the reporter, stats-gather, alerter, and client scripts. This means that I will be rewriting the scripts in Python. A couple of reasons for this; to cut down on the number of modules that are required for the installation process (which also makes distributing the client script [...]

If you have seen the following error on the Perf Report tab “Message: SimpleXMLElement::__construct()…” – it has been fixed in revision 281. This only affects alerts 11 and 12 so you might not run into it immediately. The solution is to either remove lines “586, 590, 639, 650″ from the bin/kontroll-reporter-5.0.x_linux-x86-2.0.1.pl file, or to run [...]

I’ve been messing around with the Kontrollbase schema for the last couple of days, writing various queries for the daily reporting scripts that will eventually be an automated pdf report. I’ll give you examples of two of the queries, the first being overall environment stats, and the second being single-host growth over time.

Overall environment stats
select ((((MAX(os_mem_used)) / 1024 ) / 1024) / 1024) max_os_mem_used, ((((MIN(os_mem_used)) / 1024 ) / 1024) / 1024) min_os_mem_used, ((((AVG(os_mem_used)) / 1024 ) / 1024) / 1024) avg_os_mem_used, ((((STDDEV_POP(os_mem_used)) / 1024 ) / 1024) / 1024) stdev_os_mem_used, ((((MAX(length_data + length_index)) / 1024 ) / 1024) / 1024) max_size, ((((MIN(length_data + length_index)) / 1024 ) / 1024) / 1024) min_size, ((((AVG(length_data + length_index)) / 1024 ) / 1024) / 1024) avg_size,

If you are having an issue with adding hosts/clients/users on revision 162 it’s because of the INSERT DELAYED sql command being used. Before I release a new version, please change the following lines in the file “system/application/models/mode_app.php” Incorrect code line 70: $sql0="INSERT DELAYED INTO server_list ( line 139: $sql0="INSERT DELAYED INTO `server_client` ( line 177: $sql0="INSERT DELAYED INTO `system_users` [...]

This comes rather quickly as the last revision – 150 was just uploaded a few days ago. This is because there was a new method of checking config options in the bin/ scripts that utilizes the codeigniter config files instead of config.cfg in the base directory, the problem was the all of the required bin/ [...]

This should be an interesting advance for Kontrollbase. I recently acquired a older dual 2ghz G5 PPC Power Mac running 10.5.8 and have just finished the installation of MySQL Community 5.0.85 (mysql-5.0.85-osx10.5-powerpc-64bit). I should note that the installation process is actually easier than it is on RHEL with RPMs. Quite nice. So, given this [...]

The latest version is available for download. Big changes include a debug log file view tab, redesigned system management screen, authentication ACL fixes, host state fixes for server-loop, AJAX’d user/host/client pages, data grids for all pertinent tables, and a fix for the slate theme submit button. If you are running an older version of Kontrollbase I would highly recommend upgrading. I’ll be adding an “upgrade” page to the documentation today for just that purpose.
