du2rrd, I don't see directories

[human]

I'm pretty sure I set this all up correctly. Created my cron job ( ran it manually first to be sure it worked ) RRD files is in /var/lib/du2rrd ( world readable )

The web page shows up, I see everyting except the list of directories.. or in this case directory.

I also received a pop-up error that said: "Local error 1: Local time-out expired"

I don't see anything in the apache log files

thanks!!

look at the apache log file to figure if the cgi does get run. also try running it from the commandline ... have a look at the apache error log to see where the problem is ...

hope this helps tobi

I dont see anything either, and i get the same javascript error message.

My apache log says: "192.168.119.48 - - [17/Feb/2009:14:32:19 +0100] "GET /du2rrd-0.0.6/htdocs/du2rrd.cgi?_ScriptTransport_id=1&nocache=1234877539485&_ScriptTransport_data=%7B%22service%22%3A%22du2rrd%22%2C%22method%22%3A%22get_tree%22%2C%22id%22%3A1%2C%22params%22%3A%5B%5D%7D HTTP/1.1" 200 1611 " http://dkdiskusage/du2rrd-0.0.6/htdocs/" "Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_5_6; en-us) AppleWebKit?/525.27.1 (KHTML, like Gecko) Version/3.2.1 Safari/525.27.1""

I tried looking at what actually happens to the files in /var/lib/du2rrd, and it seems like the ONLY file that gets a new date after the initial run is: status.storable

I tried using strace to run the du -k | strace du2rrd and it does open all those .rrd files.

running strace -p -o -ff on apache gives me something that might be interresting when i load the cgi

read(12, 0x820e8e0, 8000) = -1 EAGAIN (Resource temporarily unavailable)

i forgot to add that i am using version 0.0.6, but it can be seen if one looks after it.

I have the same problem, with the same error message and version 0.0.6 - the webpage comes up but the list of directories is missing.

I'm running the command by hand, to test the installation before fully configuring - and my .RRD files *are* being updated (unlike human #1)

--- CGI file:

# Point this to the location of your du2rrd data store. It seems
# perl wan't this to come only after the use-lib

};

I have noticed in version 0.0.6 that if du -k <some directoy> returns a blank line with it's stream of data, that the webpage no longer properly generates a graph for the directories being monitored. I discovered this when I captured the results of a du -k operation on some directories. the du2rrd script would generate an error as outlined inmy example below:

Use of uninitialized value in multiplication (*) at /opt/du2rrd/bin/du2rrd line 157, <> line 8959.

Use of uninitialized value in pattern match (m) at /opt/du2rrd/bin/du2rrd line 161, <> line 8959.

In the stream at line 8959 was a blank line. In the source for du2rrd there was no safe checking at lines 157 and 161, specifically:

my ($size,$path) = split /\s+/,$_,2; $size *= 1024; # sitze is in kb!

Should a blank line be inserted into the stream, $size and $path would not be initialized leading to problems. I have not had the time to fully explore the impact if this but I felt it was necessary to report.
