Updating NConf 1.2.6.0 to version 1.3.0.0

Today I found out that the NConf crew released version 1.3.0.0 of their awesome Configuration utility for Nagios. If you read my last posts, you probably already know that I´m a big fan of that project. Of course I wanted to apply the update immediately – and ignored the warnings on the NConf page 😉

To say it right from the start: Updating NConf from version 1.2.6.0 to 1.3.0.0 is not a 5 minute process, since the NConf crew changed some major parts in the inheritance and architecture. Further information can be found here:  Nconf Release Notes
Now let´s get back to the Update process. Here´s what I did (based on the official tutorial Official NConf Update How-To)

  1.  Created backup of Nconf directory with
    cp -rp nconf/ nconf.BAK
  2. Create mysql dump of the nconf database with
    mysqldump -u DBUSER -p DBNAME > nconf-dbdump.sql
  3. Unpacked the nconf archive
    tar -zxf nconf-1.3.0-0.tgz
  4. Overwrote the existing Files
    /bin/cp -rv * /way/to/old/directory/of/nconf/
  5. Checked the permissions of the following folders in the nconf directory:
    /config  /output  /static_cfg  /temp
  6. Went to the URL of the local NConf webpage
    NConf_Update
    here you can just click “update page” and will be directed into the Update procedure.
    After that you will come to a point where this information comes up. Here you have to decide if you want to move on with your old configuration scheme or switch to the new one. I did the conversation and will probably report about my experiences in a later article.
  7. After finishing the process you will see a summary of the changelog. READ IT!
    Security issue with ‘call_ajax.php’:
    Please remove this file from your nconf/ directory.
    A replacement which is more secure has been implemented (‘call_file.php’). So I did:  rm call_ajax.php 
  8. Delete Update/Installation files.
    rm –r UPDATE*

    rm –r INSTALL*

I can proudly report that the update process works as described.

Changes I checked so far (see NConf page for highres Screenshots):

  •     Look & Feel is a little bit different
  •     You can define default service templates for checkcommands (Yey!)
  •    New “advanced service” section (not figured out yet)
  •     Inheritance of variables is visible
  •     First notification interval can be set
  •     Deployment module

I have to say that the overall feeling is more solid and trustworthy than 1.2.6.0. I will write a more detailed report later.

Currently I´m trying to adapt my configuration to the new architecture, before exploring the new included deployment function. This one should replace my cronjob deployment.
