Database graphs

Database graphs display metrics for various database operations, for example, insertions and deletions. They also display a current count of database connections for the selected ServiceNow instance.

To view the details of a database, select an instance from the CI list, and then select a database operation to view. Available database operations are listed above the graph. All the traffic listed here is specific to your cluster node/instance. If you are looking at the database graph for your discovery node, it does not include traffic for your UI node or vice versa. If you, like most customers, are running on a single node, the graph shows everything.

Throughput, response, and connection use database graphs
  • Database Throughput: Displays the count (per minute) for each type of database operation (inserts, deletes, and so on) over time.
  • Database Response: Displays the response time (in milliseconds) for each type of database operation.
  • DB Connection Use: Shows how many connections this instance has open to the database. Select to display as a maximum, a minimum, or a mean.
