# Which Problems Are Solved
Using the service ping, we want to have some additional insights to how
zitadel is configured. The current resource count report contains
already some amount of configured policies, such as the login_policy.
But we do not know if for example MFA is enforced.
# How the Problems Are Solved
- Added the following counts to the report:
- service users per organization
- MFA enforcements (though login policy)
- Notification policies with password change option enabled
- SCIM provisioned users (using user metadata)
- Since all of the above are conditional based on at least a column
inside a projection, a new `migration.CountTriggerConditional` has been
added, where a condition (column values) and an option to track updates
on that column should be considered for the count.
- For this to be possible, the following changes had to be made to the
existing sql resources:
- the `resource_name` has been added to unique constraint on the
`projection.resource_counts` table
- triggers have been added / changed to individually track `INSERT`,
`UPDATE`(s) and `DELETE` and be able to handle conditions
- an optional argument has been added to the
`projections.count_resource()` function to allow providing the
information to `UP` or `DOWN` count the resource on an update.

None
# Additional Context
- partially solves #10244 (reporting audit log retention limit will be
handled in #10245 directly)
- backport to v4.x
# Which Problems Are Solved
Add the ability to keep track of the current counts of projection
resources. We want to prevent calling `SELECT COUNT(*)` on tables, as
that forces a full scan and sudden spikes of DB resource uses.
# How the Problems Are Solved
- A resource_counts table is added
- Triggers that increment and decrement the counted values on inserts
and deletes
- Triggers that delete all counts of a table when the source table is
TRUNCATEd. This is not in the business logic, but prevents wrong counts
in case someone want to force a re-projection.
- Triggers that delete all counts if the parent resource is deleted
- Script to pre-populate the resource_counts table when a new source
table is added.
The triggers are reusable for any type of resource, in case we choose to
add more in the future.
Counts are aggregated by a given parent. Currently only `instance` and
`organization` are defined as possible parent. This can later be
extended to other types, such as `project`, should the need arise.
I deliberately chose to use `parent_id` to distinguish from the
de-factor `resource_owner` which is usually an organization ID. For
example:
- For users the parent is an organization and the `parent_id` matches
`resource_owner`.
- For organizations the parent is an instance, but the `resource_owner`
is the `org_id`. In this case the `parent_id` is the `instance_id`.
- Applications would have a similar problem, where the parent is a
project, but the `resource_owner` is the `org_id`
