UsageBenutzung

Login into racktables and go to „Reports“.Nun in die Racktables Webseite einloggen und „Reports“ aufrufen.

Now you find „Server“ and „Virtual machines“ in the report menu.Man findet nun zwei neue Reiter „Server“ und „Virtual machines“ im Menü.

Note: Sort multiple columns simultaneously by holding down the shift key and clicking a second, third or even fourth column header!Bemerkung: Man kann mehrere Spalten gleichzeitig sortieren durch das gedrückthalten von Shift wärend man auf weitere Spalten in der Kopfzeile klickt!

ModifikationsModifikationen

Add custom attribute:Eigene Attribute hinzufügen:

Find the ID of your attribute. In this example it is „10002“. Open the report file „vm-report.php“ for example. And add the following componets to the file:Zuerst sucht man sich die ID seines Attributes. In diesem Beispiel ist es die „10002“. Nun öffnet man zum Beispiel die Datei „vm-report.php“ und fügt folgende Teile ein:

[...]
$aResult[$Result['id']]['myValue'] = '';
if ( isset( $attributes['10002']['a_value'] ) )
    $aResult[$Result['id']]['myValue'] = $attributes['10002']['a_value'];
[...]

[...]
<th>My Value</th>
[...]

[...]
<td>'.$aRow['myValue'].'</td>
[...]

An easy way to find the ID of your custom attribute is to look in the source code (with your browser) of the attribute setting in the configuration.Ein einfacher Weg, die ID seines Custom Attributes zu finden ist sich den Quelltext (mit dem Browser) der Attribute in der Konfiguration anzuschauen.

Note: If it is an standart value and not an attribute (Don’t listed in attributes in the configuration menu) you can directly access the values:Bemerkung: Falls es sich um einen Standartwert handelt und nicht um ein Attribut (Nicht in der Attributliste im Konfigurationsmenü enthalten) kann man den Wert direkt auslesen:

Example with asset Tag:Beispiel mit Asset-Tag:

[...]
$aResult[$Result['id']]['sAssetTag'] = $Result['asset_no'];
[...]

[...]
<th>Asset Tag</th>
[...]

[...]
<td>'.$aRow['sAssetTag'].'</td>
[...]

Custom sorter:Eigene Sortierung:

I have a lot of servers like vServer1, vServer2, …, vServer11, etc. but i want to list vServer10 after vServer2 so i created a custom sorter.Ich habe jede Menge Server mit Namen wie vServer1, vServer2, … vServer11, etc. und ich möchte vServer 10 nach vServer2 in meiner Liste haben. Deswegen habe ich eine eigene Sortierung gebaut.

First create a new file in the jQuery-Folder called „sorter.js“ with the following content:Zuerst erstellt man eine neue Datei mit dem Namen „sorter.js“ im JQuery-Verzeichnis mit folgendem Inhalt:

$.tablesorter.addParser ( {
    id: 'vserver',
    is: function(s) {
        return false;
    },
    format: function(s) {
        s = s.replace(/<a\b[^>]*>/i,'');
        s = s.replace(/[^0-9]+/g,'');
        return s.trim(s);
    },
    type: 'numeric'
});

Now open your report file „vm-report.php“ for example and add:Nun öffnet man seine Report Datei wie zum Beispiel „vm-report.php“ und fügt folgendes hinzu:

First the include of the new JS-Sorter:Zuerst den neuen Sorter einfügen:

"echo '	<script type="text/javascript" src="extensions/jquery/sorter.js"/>';"

And below the table in the tablesorter JS-Part:und unterhalb der Tabelle im Tablesorter JS-Teil:

[...]
headers: {
  0: { sorter: "vserver" },
  3: { sorter: "ipAddress" }
}
[...]

This sorter removes the hyperlink (added by the report) and all text parts from the name of the server (only for the sorting) and sorts the column now numeric.Dieser Customsorter entfernt den Hyperlink (durch den Report hinzugefügt) und alle Textteile vom Servernamen (nur für die Sortierung) und sortiert den Rest nummerisch.

  1. You my friend, are a rockstar! This is a great addition to RT for sure!

    Question, is version 0.20 generally available? If not, how did you get it?

    Antworten

  2. I am using Racktables 0.19.3 and observe the following error. How to fix it?

    PHP Warning: require_once(extensions/reports/server-report.php): failed to open stream: Permission denied in /var/www/html/racktables/inc/local.php on line 4

    Antworten

  3. It was caused by the selinux.
    Finally I work around this issue by execute setsebool -P httpd_read_user_content=1 as root
    I am using Centos 6.3.
    If I don’t want to change the selinux policy and set httpd_read_user_content=1, what others I can do to fix it?

    Antworten

  4. I found the fix finally.
    Change to the racktables dir and execute to reset the SELinux security contexts
    restorecon -Rv extensions/

    • Hi,

      thank you !

      I’m currently working on version 0.3 of the extension with some new features.
      I hope to release it with racktabes 0.20.0 so i can remove a lot of stuff from the sourcode i need to be compatible with some older versions of racktables.

      Add it to contrib is a good idea, the racktables developers should decide if they want to add it to the core.

  6. Does anyone have this running under version 0.20.0? I have it running fine under 0.19.13 but when trying the new plugin location setup on 0.20.0 it never loads. Any ideas? Thanks for your work on this!!

    Antworten

    • Hi,

      it works on racktables 0.20.0 ( i developed it on 0.20.0 )

      Did you follow the instructions for version 0.20.0 ? Only the extension.php should be in the plugin directory. The plugin requests some files (JQuery and CSS) from the webroot. The rest of the plugin must stay on its old position.

      Greetings

  8. Hi,

    extension folder is in the webroot of racktables and extension.php in the plugin directory ?

    Old local.php removed (replaced by extension.php in v 0.20.0)

    Greetings

  9. I think there is a problem reading the path.

    My directory structure is c:\www\racktables\extensions\

    The server is publishing as http://servername/racktables

    How does the extension.php plugin path need to be set?

    require_once „../racktables/extensions/reports/server-report.php“;

    Does not appear to be read at all.

  10. Hi
    When i tried to install over 0.20.3, i can’t see the new reports, is there anothe configuration for this version of RT?

    Antworten

  11. Documentroot: /var/www/html/racktables

    I installed racktables 0.20.9. I downloaded racktables_extensions_v0.3.1-5.tar and then tar xvc racktab****.tar -C /var/www/html/racktables/ ; cd /var/www/html/racktables
    mv racktables_extension* plugins; cd plugins; mv extensions ../. ;
    But not working.

    Antworten

    • Hi,

      please ask your server administrator i think it is an permission problem.

      The white pages are probably PHP Errors. ( There is no output defined for PHP Errors, thats default configuration of PHP. )

      The Error you posted:

      PHP Fatal error: require_once(): Failed opening required ‘/var/www/html/plugins/extension.php’

      This may be because your webserver is not allowed to open the plugin file.

      But i’m not sure. This are not directly problems with this plugin or racktables. Please ask your system administrator to check the webserver configuration and the permissions and flags of your files.

      Greetings

  12. Hi,

    im using racktable 0.20.9 on CentOS
    root folder is /var/www/html/racktable

    i copied the “extensions” folder in to:
    /var/www/html/racktables
    there is no folder named “plugin” so i created one and add the file
    /var/www/html/racktables/extension.php
    now.. there is no wwwroot folder (not using windows iis)
    so i canged the path to “require_once “/extensions/reports/server-report.php”;”
    still nothing working..
    any ideas?

    Antworten

      • Thanks for answering.
        There are no such file in my installation.
        Can you assist by explaining what folders to add?
        my root folder is:
        /var/www/html/racktables
        in it i have:
        css inc index.php js pix
        Do i need to reinstall the application or can it be fixed?

        Thanks.

        Antworten

        • Hi,

          you installed racktables wrong.

          css, inc, index.php js and pix are the content of the wwwroot directory if this is your /var/www/html/racktables directory, than put your plugins directory under /var/www/html/plugins.

          Antworten

          • I tried that but whenever i put the “extension.php” in /var/www/html/plugins
            i am getting blank (white) pages
            i tried to change the content of the extension.php to use:
            require_once “/var/www/html/racktables/extensions/reports/server-report.php”;
            but still not working all im getting is blank pages.
            ideas?

            thanks in advanced

          • White pages may be php errors. Turn on your debug output. Or check apache error log.
            Pathes (plugin and folders) seems to be correct now.

          • Thanks for the comment, i found this in the error log of the apache:
            PHP Fatal error: require_once(): Failed opening required ‚/var/www/html/plugins/extension.php‘ (include_path=‘.:/usr/share/pear:/usr/share/php‘) in /var/www/html/racktables/inc/init.php on line 146, referer: http://my-site/racktables/index.php?page=report

            and in the /var/www/html/racktables/inc/init.php

            / load additional plugins
            ob_start();
            if (FALSE !== $plugin_files = glob („${racktables_plugins_dir}/*.php“))
            foreach ($plugin_files as $plugin_file)
            require_once $plugin_file;
            // display plugins output if it contains something but newlines
            $tmp = ob_get_clean();
            if ($tmp != “ and ! preg_match („/^\n+$/D“, $tmp))
            echo $tmp;
            unset ($tmp);

          • That the problem, whenever i put the extension.php in the plugin dir
            the site stop working (show blanks pages) until i delete the file

          • excuse my ignorance but what is “Failed openin” or more important where can i configure it?
            Thanks

  13. I tried that but whenever i put the „extension.php“ in /var/www/html/plugins

  14. Dear Sebastian,

    Thanks a lot!
    It works for me in 0.20.0. I can now see these three new pages in Report tab.

    You save me a lot of time by using this.

  15. This worked great!

    I managed to add other attributes in the report, but I am having some trouble including the Location Name in it. Can anyone help me with this please?

    Also, is there a way we can do bulk upload of data?

    Best regards,
    RJ
