Dashboard block installs the usual way in moodle:
There are at least 3 features that may need global configuration by the moodle administrator. These are located into the Site administration > Plugins > Blocks > Dashboard
administration menu:
The Dashboard block was designed initially to publish in moodle some external data reports comming from an associated ERP. the dashboard still has this alternate data source definition (PostGreSQL only) that may be used by some dashboard block instances if required.
On heavy duty moodles, some queries may accidentally process a very lot of data and may require a DB server load that is incompatible with usual production. the following parameters setup some protection against such “big results” requests.
the following parameters give some default values for the file export scheduled batch. these settings may be locally overriden in the block instance.
