> store and query data as I have described, but I am wondering if I am > reinventing the wheel. Does a tool such as this already exist? Yes. You are describing a feature of Save/Compare/Restore applications. SCR are also know as epics-backup application (i.e take a snapshot of a running machine, compare 2 snapshots, compare a snapshot with the running machine) You next question is where to get such a piece of software. Well... I am using SDDS save/compare/restore (very old) SCORE may have the described feature as well (used at SNS and SLAC) <Shameless plug for MASAR> I am currently looking at MASAR part of epics-4, which is straight forward to install, but still in development. For example, comparisons of 2 snapshots using the pyQt GUI is missing. A CSS GUI is also a work-in-progress. At this time, most of the development is at the GUI level So if you don't mind a text output (i.e. in a terminal), you can use MASAR with its python API and have something working by tonight. </Shameless plug for MASAR> |
