Re: [Tauruslib-users] [tauruslib-user] taurustrend --use-archiving - problem

[Carlos P. <cpa...@ce...>]

Hi Lukasz,

As I said, I am personally not an expert on archiving. Sergi Rubio (in 
CC)  is the author of the archiving support of TaurusTrend, so he may be 
able to give better help.

With my limited knowledge, all I can suggest is:
1- make sure you use Soleil's archiving system (according to srubio, it 
doesn't work with other archivers)
2- make sure that your attribute (let's say "a/b/c/d") is configured in 
the archiver and also that its values are really being archived (*)
3- launch taurustrend a/b/c/d
4- use the context menu to enable archiving (righ-click->use archiver)
5- Now go to plot configuration (Right-click->plot configuration) and 
disable the "Fixed-range scale" checkbox. Then enter a start value 
previous to the time when you launched the trend (step 3). Apply and 
Close the configuration dialog.

You should be seeing archived values now.

(*) Note: this is crucial, but it is where I cannot help you much since 
I've never done this myself. I guess you can do a mysql query against 
the DB, or use Mambo...
