Problem with Browsing rrd files - Nav-users

10 Jul 2006


      ...
Then navigate directly to
http://NavServer/browse/rrd (typing nothing after rrd), without clicking
your way to the rrd browser from somewhere else in the interface.
When I do this, I get a Search menu, with DataSource and a text box, and
search button, and below that a Category box with buttons "Add Selected",
"Add and join", and Cancel.
I can't seem to do much from here - If I click on anything in Category, it
selects it, and then almost immediately unselects it - buttons don't seem
to do much at this point!
The Current path at this point is Home > IP Device Center
I will take another look at rrdtool and pyrrdtool while you are thinking
about this....

Morten,
 If I manually enter the url, I get the same result - segfault and

blank screen.      If I change the rrdBrowser.conf file to point to a
non-existent location, IE, instead of /tmp/rrd_ as the prefix, I use just
"rrd_", then I get a menu with "year month week day hour" and some choose
action items.    But, obviously, no graph.
That's not what your supposed to see at all.  The rrdBrowser stores most
of its interactive state in your user session, which is why I asked you
to completely close your browser (to remove anything left in your
session data) - alternatively log out of NAV or remove the NAV cookie
from your browser.  Then navigate directly to
http://NavServer/browse/rrd (typing nothing after rrd), without clicking
your way to the rrd browser from somewhere else in the interface.
Even typing a non-existant location in your rrdBrowser.conf should not
take your a menu with "year month week day hour" when typing that URL
directly...
This is really hard to debug, since a segfault can only stem from native
code - which NAV doesn't contain at all.  The best way would probably be
to debug the apache process, but that could prove really ugly.  If the
path we're on right now doesn't lead anywhere, I'm not really sure how I
can help you, short of suggesting that you reinstall rrdtool and
pyrrdtool completely, just to see what happens.
