Hdb_viewer - TANGO Controls

# 7 years ago
TCS_GMRT	Can anyone point me to the Hdb++ detailed documentation required from developers perspective - API documentation/details etc. so far I could only find this : http://www.tango-controls.org/media/filer_public/76/f5/76f51368-a45a-45bb-abfe-da7cd9b90b32/wed3o04.pdf but this is providing more of functional overview of the tool. Thanks Regards, TCS_GMRT

TCS_GMRT	Hi Jyotin, Thank you for your quick response. I need more information/details about jhdbviewer. In above documentation, It is not clear that how all the things are working in jhdbviewer. Can you provide me detailed documents for the same? Regards, TCS_GMRT

Po	Hi TCS_GMRT, I don't have any document for jhdbviewer. However, I think going through the jhdb viewer source code is a good start. Maybe someone from the Tango Forum can help you with the documentation available, if any. Kind regards, Jyotin Edited 7 years ago

TCS_GMRT	Hi Jyotin, Thank you for your valuable suggestion. Can anyone from the Tango Forum have some documents for the jhdviewer? Is there python API available for jhdviewer? Regards, TCS_GMRT

Reynald	Hi, It seems there is a misunderstanding here… jhdbviewer is a graphical user interface written in Java to retrieve and display data which is stored in HDB++ database. Can you please describe more precisely what you would like to do? Are you looking for a python API to extract data from HDB++?

TCS_GMRT	Hi Reynald, Yes, you understood it right. We are looking for a python API to extract data from HDB++. Additionally, we are also looking for a time based dynamic chart in the jhdviewer. Currently jhdviewer displays chart based on stored data(Attached). Can we have dynamic feature as well? Regards, TCS_GMRT Attachments:

Reynald	TCS_GMRT Yes, you understood it right. We are looking for a python API to extract data from HDB++. You can use PyTangoArchiving as described in this post from Sergi Rubio: http://www.tango-controls.org/community/forum/c/general/installation/gui-for-hdbextractor/?page=1#post-433 TCS_GMRT Additionally, we are also looking for a time based dynamic chart in the jhdviewer. Currently jhdviewer displays chart based on stored data(Attached). Can we have dynamic feature as well? I think the archiving browser from pyTangoArchiving is already providing such a feature (I guess you meant you want to see live data too?). This feature will probably be added into JHdbViewer in the future too. Rosenberg's Law: Software is easy to make, except when you want it to do something new.

Reynald	Since the time when Sergi posted that message, I think now it can work as well with new HDB++ schema and with Cassandra too… Sergi can probably help you if you need more details about that.

TCS_GMRT	Hi Reynald, Thank you for response. Is it also available for Hdb++? Regards, TCS_GMRT
