Integration with CRIC

The Computing Resource Information System (CRIC) is a framework providing a centralized and flexible way to describe resources and their usage.

It is possible to integrate PanDA and CRIC so that administrators register various resources in CRIC by using WebUI and PanDA fetches information from CRIC, avoiding manual registration in the database. One of the scripts launched by PanDA daemon, configurator, periodically retrieves information from CRIC and populates database tables. To enable PanDA daemon and configurator, you need in panda_server.cfg

[daemon]
# whether to run daemons for PanDA
enable = True

config = {
    ...
    "configurator": {
        "enable": true, "module": "configurator", "period": 200, "sync": true},

and set the following parameters:
