well.... once again you're right !! :wink: looks like one of the values is not correct..... perhaps one of the DS type chosen is wrong ?? anyway... my blocks*1024 is widely > to cache_size... and actually cache_size is rather low wrt to what it should be... i'll see what i can do about it, thanks ag...

so, back now and here is the remainder. I forgot to explain th *1024 thing... actually i am graphing (willing to...) the key_cache usage of MySQL. so on the one hand i get key_cache_size in bytes (fixed value) and on the other hand i get key_used_blocks..... which i have to multiply by the block_siz...

i checked cmd.php output, there was a problem which i corrected, but still no graph the 2 DS debug outputs look good but the graph debug output shows nothing.... i just have an empty image placeholder + "RRDtool says : " and that's all, no text after that.... what i lack is a CDEF debugger...

well... my CDEF is the following (it compares sizes not queries...) : cdef=(CURRENT_DATA_SOURCE,1024,*),ALL_DATA_SOURCES_NODUPS,(CURRENT_DATA_SOURCE,1024,*),-,/ and my graph is defined with first item : the total (represent as a line with no color) 2nd item : the number of blocks (thus the *1024) de...

ah !
interesting !
so the all_data_sources_nodups sums up data from all data sources *defined in the graph* only ?

because in cacti i have of course other data sources...
ok i'll have a look at this see if i can figure out how to do it from your start.
if i can't, i'll post further.

thanks !

hi, i'm interested in graphing ratios with data coming from 2 DS using the same DIM. unfortunately, i haven't found so far... of course i could modify the script and create one which does the ratio and so create a nez DIM and a new DS, but then, nothing is really generic anymore if i must create a n...

well.... hum ! ....

looks like you were right once the cron output redirected to a file....
actually, i re-read the crontab manpage and looks like path is not even set !

thanks for the help !!

well actually, as cmd.php launches itself without any problem, i don't think it is a PATH problem for the PHP executable.

and the script itself is pretty straightforward and uses no external binary

well i'll try and crawl through the cmd.php code and see how the "U" is computed...

hello, i'm trying to use the "additionnal script" sql_stat.php on my linux server but i have a strange behaviour which i can't sort out.... if i launch cmd.php by hand, i get the following output which is correct Manual output for cmd.php bash-2.05$ ./cmd.php [...] command: php -q /home/ww...
