mg_kvedit provies a graphical editor for the contents of the key value store. In the command invokation, configuration-file is the manager database configuration file.
The key value store associates arbitrary keys with arbitrary values. It can be used by applications to store metadata required by their applications. It is also used by standard components of the managed DAQ system. These components define the following keys:
This is used to set run titles in compatible Readout programs. It contains the desired title for the next run.
Is used to set the run number in compatible Readout programs. It contains the desired run number for the next run.
The editor provides a window that, at the top, contains a table of key/value pairs. At the bottom is an editing region that provides entries for a key and a value. Selecting (by clicking) a key value pair in the table loads the key and its value into the editor fields where either or both may be modified.
Clicking the button updates the table. If the key is an existing key its value will be modified. If it is a new key, a new key/value pair will be created.
Clicking on the button removes a key and its value from the table.
Note that none of the edits described above affect the database. The button writes all changes to the database key value table.
