NTop fonts in RRD graphs are Squares.



  • Nothing I do seems to fix the nTop RRD graphs from showing squares instead of actual characters.

    I am running the latest PF (2.2) and just re-installd nTop again.

    No luck.

    All other RRD graphs look right.

    Any thoughts?



  • I'm running ntop-ng, not ntop, however, while looking at an unrelated problem, I noticed some broken symbolic links for ntop-ng fonts.
    I found them using this command:

    find / -type l ! -exec test -r {} \; -print
    

    I fixed it by creating this symbolic link:

    ln -s /usr/pbi/ntopng-i386/local/etc/fonts/ /usr/local/etc/fonts
    

    Whether or not that does anything for the rrd graphs, I don't know, since I have no idea how to get the ntop-ng rrd graphs to show up.  ???
    I find lots of .rrd files under /var/db/ntopng, but no clue how to get them to show up in status->rrd graphs.



  • Hello,

    I just wanted to give you the solution that worked for me. I had the EXACT same issue as you and I'm sure others are having it too.

    If '/usr/local/etc/fonts/' doesn't exist on your system do the following steps.

    1. log into your server
    2. push 8 for a shell prompt
    3. type 'pkg install xorg-fonts-7.7'
    4. after it installs restart the server
    5. check ntop and all should be well.

    Thanks,

    Tom



  • Tom,

    Thanks for this solution. It worked great for me on 2.2.1. I'd like to add that I didn't have to restart the firewall. I just stopped and started ntop, and the display updated fine.

  • When I enter the following command:

    pkg install xorg-fonts-7.7

    I get the following response:

    Updating FreeBSD repository catalogue…
    FreeBSD repository is up-to-date.
    All repositories are up-to-date.
    pkg: No packages available to install matching 'xorg-fonts-7.7' have been found in the repositories

    Any ideas?

    thanks!



  • A newer package has been released.

    While searching for the same issue I found that running the following showed the correct version.

    pkg search xorg-fonts
    

    I then ran:

    pkg install xorg-fonts-7.7_1

    Thanks for the tip - the newer fonts have been installed.  However, that did not solve the problem.  So, I manually created the link as recommended by ESPNSTI:

    ln -s /usr/pbi/ntopng-i386/local/etc/fonts/ /usr/local/etc/fonts

    …and re-started both ntop, then  the entire firewall...with the same results (Squares for text on ntop RRD graph on both Chrome and IE).  Any other ideas?

    BTW - bandwidthd's graphs all look good - I just prefer nTop's data...

    Thanks!

    I've given up, at least for now, and am trying ntopng.  I am hoping for something shiny to show folks in part to help justify some much gruntier hardware for this project.  Letting them drive off an unpaved roadbed into those weird boxes -  a total nonstarter.



  • Hello,

    I have the same problem. Please, someone an idea to fix this font problem when generating the graphs in ntop?

  • I'm not sure that this will help with your problem.

    I have noticed older OS's do not display new fonts correctly.



  • this is STILL a problem with 2.2.6-RELEASE (amd64) built on Mon Dec 21 14:50:08 CST 2015 …

    I installed the latest xorg-fonts-7.7_1  and I'm quite hesitant to do that symlink since both directories exist (its -amd64 rather than -386 on my system).

    /usr/local/etc/fonts:

  • Directly looking at the Makefile of Ntop in FreeBSD @Ports the URW fonts package is marked as a dependency:

    
    LIB_DEPENDS=    libgdbm.so:${PORTSDIR}/databases/gdbm \
                    libevent.so:${PORTSDIR}/devel/libevent2
    BUILD_DEPENDS=  rrdtool>=1.2:${PORTSDIR}/databases/rrdtool \
                    dot:${PORTSDIR}/graphics/graphviz \
                    geoiplookup:${PORTSDIR}/net/GeoIP
    RUN_DEPENDS:=   ${BUILD_DEPENDS} \
                    urwfonts>0:${PORTSDIR}/x11-fonts/urwfonts
    
    

    this can be installed with: pkg install urwfonts.

    I haven't narrowed this down yet 100% but am working on it, since this isn't a fix but getting closer I feel…. (as have just started with PFsense though I know FreeBSD pretty well).

    Also under the path:

    /usr/pbi/ntop-amd64/local/fonts/conf.d

    there is a file called:

    30-urw-aliases.conf

    whose contents look like this:

    
     <fontconfig><alias binding="same"><family>Zapf Dingbats</family>
    	  <accept><family>Dingbats</family></accept></alias> 
    	 <alias binding="same"><family>ITC Zapf Dingbats</family>
    	  <accept><family>Dingbats</family></accept></alias> 
    	 <match target="pattern"><test name="family" compare="eq" ignore-blanks="true"><string>Symbol</string></test> 
    	  <edit name="family" mode="append" binding="same"><string>Standard Symbols L</string></edit></match></fontconfig> 
    
    

    I think (though I maybe totally wrong) that this might have something to do with the fonts not displaying…. as in a missing symlink or path location to the urw font package??

    Still investigating however.....
