How you log on the system depends on a few preconditions:
- Whether or not you installed Core services on a server machine which is part of a domain which recognizes your personal user account
- Whether or not you explicitly specified a system owner user account
Figure 105:Screenshot of the logon dialog
When the system is first installed, or more appropriate, when the master Core service is first installed, a System object is created with the name ‘System’ and a description which indicates that the object has been created by default during system installation.
The Core service is installed mandatorily with a new installation of system:inmation so the Core object will be visible beneath the system object when you first login using DataStudio. The Core object automatically takes the host computer name (where the Core service is installed) as its object name although this can be changed in the object properties panel along with any other properties (see DataStudio documentation for more information). The same recommendations about naming convention apply to the Core as to the System object.
If the default options were chosen at installation then the Core will be ready to receive information from the Connector service or any other objects. You will first need to create the objects beneath the Core though (see DataStudio documentation for more information).
The MongoDB installation will setup separate data stores for different data types and logs.
- Time Series Data Store
- Event (A&E) Data Store
- Logging Data Store
- Custom Data Store
The configuration for each DataStore is set in the System Object's properties panel.

Each Data Store can have separate Latency and Buffer configurations and the MongoDB connection settings can also be configured differently with different Authentication modes and Usernames and Passwords. Replication Sets can also be configured.

During setup, the MongoDB connection settings regarding authentication mode, user name and password can be set globally in Advanced settings and then changed later. See the installation guide for more details.
The upgrade to system:inmation 1.44 may create a situation where the System object displays a yellow warning state after upgrade. This is sometimes the case with deployments with MongoDB CR or SHA authentication, that did not use the repository “Custom-Datastore” before.
To correct this, enter credentials in the Custom Data Store in the following properties with your chosen authentication mode:
