 Azure SQL Database provides several metrics that are relevant for this type of monitoring. Exceeding the recommended average value for each metric indicates resource contention in the pool, and should be addressed using one of the actions mentioned earlier.
 
-To send an alert when pool resource utilization (CPU, data IO, log IO, workers, etc.) exceeds a threshold, consider creating alerts via the [Azure portal](alerts-create.md) or the [Add-AzMetricAlertRulev2](/powershell/module/az.monitor/add-azmetricalertrulev2) PowerShell cmdlet. When monitoring elastic pools, consider also creating alerts for individual databases in the pool if needed in your scenario. For a sample scenario of monitoring elastic pools, see [Monitor and manage performance of Azure SQL Database in a multi-tenant SaaS app](saas-dbpertenant-performance-monitoring.md).

-Others scenarios pack multiple tenants together into databases, rather than isolating them into separate databases. This pattern is a typical **multitenant sharding pattern** - and it might be driven by the fact that an application manages large numbers of small tenants. In multitenant sharding, the rows in the database tables are all designed to carry a key identifying the tenant ID or sharding key. Again, the application tier is responsible for routing a tenant's request to the appropriate database, and this can be supported by the elastic database client library. In addition, row-level security can be used to filter which rows each tenant can access - for details, see [Multitenant applications with elastic database tools and row-level security](saas-tenancy-elastic-tools-multi-tenant-row-level-security.md). Redistributing data among databases might be needed with the multitenant sharding pattern, and is facilitated by the elastic database split-merge tool.

 ### Move data from multiple to single-tenancy databases
 When creating a SaaS application, it is typical to offer prospective customers a trial version of the software. In this case, it is cost-effective to use a multitenant database for the data. However, when a prospect becomes a customer, a single-tenant database is better since it provides better performance. If the customer creates data during the trial period, use the [split-merge tool](elastic-scale-overview-split-and-merge.md) to move the data from the multitenant to the new single-tenant database.
