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

[Sergi R. <sr...@ce...>]

Well, to check if your attribute is archived or not:

 > ipython
# import PyTangoArchiving
# attribute = 'a/b/c/d'
# rd = PyTangoArchiving.Reader()
# rd.is_attribute_archived(attribute)

if the result is True, ask for the last hour values

# rd.get_attribute_values(attribute,-3600)

If the result is False or exception, please reply with your output

To add the attribute to archiving:

# hdb = PyTangoArchiving.ArchivingAPI('hdb') #or tdb for temporary archiving
# hdb.start_archiving(attribute) #To archive every minute
# hdb.start_archiving(attribute,{'MODE_P':[15000]}) #To archive every 15s

If it fails, reply to this email with your output. The arguments for 
start_archiving
are described in the ArchivingManager documentation.

For using tdb you have to configure the DB maintenance/cleanup in your
DB server, you can ask Soleil regarding that.
