The base system comes with Microsoft System Center Operations Manager (SCOM) metric event rules. SCOM metric event rules bind event metrics to configuration items (CIs).  
When an event's metrics match the event filter conditions, the metrics bind to the indicated CI. The event rules that come with the base system are:{#scom-event-rules__table_tq5_pb2_p1c__entry__2}

| Rule Name | CI type |
|-|-|
| SCOM Metrics - Windows Server | cmdb_ci_win_server |
| SCOM Metrics - IIS Web Server | cmdb_ci_microsoft_iis_web_server |
| SCOM Metrics - SQL Server Reporting Services | cmdb_ci_db_mssql_reporting |
| SCOM Metrics - MS SQL Database | cmdb_ci_db_mssql_database |
| SCOM Metrics - MSFT SQL Instance | cmdb_ci_db_mssql_instance |
[Table 1. Base system metric event rules]

{#scom-event-rules__table_tq5_pb2_p1c}

You can create a custom event rule to bind metrics with other CI types. For details, see [Create or edit an event rule](https://servicenow-prod.fluidtopics.net/S0ulPjfvh7Pz7phgkfVYFw "You can create event rules to generate alerts for tracking and remediation. Use team-based integrations in event rules to make sure that connector ownership and execution of rules give precedence to general rules. Teams can maintain consistency and hierarchy while offering flexibility and customization options.").

If the event rule filter doesn't match, the default rule, SCOM Metrics - Default (CI type = cmdb_ci_hardware) is invoked. The order number of the default event rule must be higher than the
order number of any SCOM event rules (both those that come with the base system and any custom rules), so that all other rules are checked for matching before invoking the default rule. For details on event rules, see [Event rules](https://servicenow-prod.fluidtopics.net/NAsCQ7ocCYVbIwhpy8vV2w "Use event rules to generate alerts for tracking and remediation. Event rules are stored in the Event Rule [em_match_rule] table. Configure and customize event rules to manage events and alert generation.").
