    Map can not be generated… Is attachments readable or issue with twopi

    Posted by keith_opswat on noviembre 1, 2010 at 18:48

    Hi everyone. I hope this is the correct location to post this questions and that it’s not too basic.

    Anyways, I have the console, server & agent all up and running on a Centos 5.5 installation. I’m running Apache 2.2.3
    php 5.3
    mysql 5.0.77

    with the latest Pandora FMS.

    I can login to my console and see a couple agents that I have setup on different machines. Linux & windows both…

    My issue is when I try to view the map I get the following error

    Map could not be generated
Apparently something went wrong reading the output.

Is /var/www/php/pandora_console/attachment readable by the webserver process?

Is twopi (usually part of GraphViz) and echo installed and able to be executed by the webserver process?

    For troubleshooting purposes I changed the permissions of the attachments folder and all sub-directories to 777. When that didn’t resolve anything I changed the permissions of my entire webfolder to 777. Still no dice…

    I have graphviz installed, graphviz-php and webdot. If I type twopi (which I don’t really know exactly what it does just a general idea since it’s related to graphviz and the map can’t generate without it haha). Like i said if I type in twopi -v into the console I get the following

    twopi - graphviz version 2.26.3 (20100126.1600)
Activated plugin library: libgvplugin_neato_layout.so.6
Using layout: twopi:neato_layout

The plugin configuration file:
        /usr/local/lib/graphviz/config6
                was successfully loaded.
    render      :  dot fig gd map ps svg tk vml xdot
    layout      :  circo dot fdp neato nop nop1 nop2 osage patchwork sfdp twopi

    loadimage   :  (lib) eps gd gd2 gif jpe jpeg jpg png ps svg

    Does anyone know what I can do to fix this issue or if it means I did something wrong during the installation?

    Thanks a lot for your time.

    Ok.

    Could you check where is installed the Pandora Console?

    Bye, thanks.

    Pandora Console is located under /var/www/php/pandora_console

    I changed the DocumentRoot to /var/www/php in my httpd.conf

    Everything appears to be working fine except for generating the map.

    Thanks for the reply.

    I’ve setup another install…

    And I still have the same issue.

    This time I’m running from the normal web-root

    /var/www/html/

    When I ran the console installation it showed that I had all the dependencies installed. I have no idea what I could be doing wrong.

    Well… I just installed Graphviz from RPM and it now works.

    So just figured I would post that I had solved the issue.

    I don’t understand why it didn’t work from source. During the ./configure it said that Twopi was installed by default and that the php module was being installed. It did a make and make install without an error. However, I guess something was wrong.

    Thanks for taking the time earlier though. Just don’t want you to spend anymore time on it sinc ei have it working now.

    Thanks a lot and thanks so much for the amazing product!!!
