We have a tiered app/solution generated with ABP Suite. We're looking to add Hangfire support to this solution. Following the documentation that describes the steps (https://docs.abp.io/en/abp/latest/Background-Jobs-Hangfire), we were able to install the package with ABP CLI, as suggested. My understanding is that we don't need to do anything extra. When we run the solution it fails at runtime with the following error:

Volo.Abp.AbpInitializationException
  HResult=0x80131500

  This exception was originally thrown at this call stack:
    [External Code]

Inner Exception 1:
DependencyResolutionException: An exception was thrown while activating λ:Volo.Abp.Hangfire.AbpHangfireBackgroundJobServer -> λ:Hangfire.JobStorage.

Inner Exception 2:
InvalidOperationException: JobStorage.Current property value has not been initialized. You must set it before using Hangfire Client or Server API.

Steps to reproduce:

• Generate a new solution, and make it run
• Add Hangfire support via ABP CLI (as per documentation)

Questions:

• What might be the issue here
• How do we access Hangfire Dashboard (it's not clear from the docs)

We're looking to create a proper reporting solution on top of a tiered ABP template/application. We're not interested in searching/evaluating reporting components per se at this stage, but rather we're looking for a general approach to organizing reporting. Here are some inputs/given:

• The initial migration provisions four distinct databases for a solution (Identity management, Tenant mgmt, Application database, etc.)
• Every tenant in our app may have their own (separate) database instance (separate database, separate schema approach)
• The initial solution has a public site and the back-office part (for tenant/permission/feature management etc.)

We need to build some simple tenant-specific reports. Let's take the "file upload" functionality as a hypothetical example. Tenants need to know how many files they have uploaded daily/monthly/annually, etc. In this case, reporting is not a big deal as we can query this data from the tenant's database context. Reporting becomes a problem when we have hundreds of tenants with their own/dedicated database, and we (as a service provider) need to gather aggregated data from all those tenants (and display it on the back-office site). What's the recommended approach in this case? Creating a Data Warehouse? Also, querying against the live transactional DB is not a good idea, given that report generation may spoil the user experience and affect the app's performance. For this matter, a read-only replica for reporting solution would be a better idea, but it doesn't help much with many tenants who have a dedicated database. What's ABP's recommendation here?
