Hi
First thanks for this good program.
If i start  dsc-grapher.pl (select Server) in the browser, i get ?Premature
end of script headers?.

Here the error log file from Apache.

This looks to me like the "ploticus" program was not found on your
system.  The code looks for it at /usr/local/bin/ploticus and
/usr/local/bin/pl.

Maybe it was installed as a different path on your system, such as
/usr/bin/ploticus?  If so I should update this code.

Hi
The error is no longer present with the most current version of ploticus.


But i have now the problem that with the legends no text is shown.
The individual legend colors are visible, however the text is missing.

An idea?

Thanks for your assistance

Hi Stefan

I have had similar issue when using Ploticus 2.41. I found a way around by
installing Ploticus 2.33 first, and then Ploticus 2.40 and finally Ploticus
2.41 (with this order..) and after that I seem to have no problems
displaying stats.

Howdy all,

I've been playing with DSC for a few days now and am wondering how I would
go about accomplishing recording just the client IP address and the record
they queried. From there I'll take the dataset and run my own presenter over
it as well as the DSC one.

Could this be done by a filter rule, or would I be really looking at
altering the sources?

TIA
AJ

Hi AJ,

There is some good news/bad news.

The good news is that the collector part should be easy to customize.  You could
create a dataset such as:

    dataset client_and_qname dns ClientAddr:client Qname:qname queries-only;

The resulting XML file sent from collector to presenter might be pretty
big, depending on how busy your nameserver is.

The bad news is that the presenter won't know how to handle this new dataset.
If you do nothing, I think you might see some warnings in some of the cron
job output.  You won't see any .dat files or graphs for this dataset.

If you want .dat files and/or graphs, you have to decide how the data
should be stored and displayed.  Then write some perl code to do that.
I can give advice if it gets to that point.

If you just want the data to be collected, you could write your own
XML reader and then do something else with it after that...

Duane W.

Hi Duane,

Yes that works fine. As for the presenter, well I am taking the output and
passing it through an XML transform for processing by another app (this is
not to say the presenter is not great, it is, we have a slightly different
use case happening here) .

This works quite well. However I'd like to extend it further so its more
multidimensional (clientip, qtype, qname, rcode etc) as otherwise my
transform is too flaky as its trying to guess too much at times. I
understand DSC logs in 2 dimensions so maybe I will have a look at this
aspect and see it I can do anything.

For the moment however I have enough to go on anyhow.

Many thanks
AJ

Yes, its 2-dimensionalness is hard coded.  For example, in md_array.h you see:

struct _md_array {
     const char *name;
     filter_list *filter_list;
     struct {
         indexer_t *indexer;
         const char *type;
         int alloc_sz;
     } d1;
     struct {
         indexer_t *indexer;
         const char *type;
         int alloc_sz;
     } d2;
     dataset_opt opts;
     struct _md_array_node *array;
};

So to extend it, you might have to start there and add more indexing dimensions.
