[GitHub] [pulsar] klevy-toast opened a new issue #13863: Add ability to disable statistics reporting at namespace level

klevy-toast opened a new issue #13863:
URL: https://github.com/apache/pulsar/issues/13863


   **Is your enhancement request related to a problem? Please describe.**
   In our pulsar cluster, we are running into issues due to the number of metrics being reported. We would like to disable the `exposeTopicLevelMetricsInPrometheus` setting for a subset of our topics that have many subscriptions, but keep it on for other topics where we need those statistics. Currently, this can only be configured in `broker.conf` as a global setting.
   
   **Describe the solution you'd like**
   Add new namespace settings to configure statistic generation, like: 
   - `pulsar-admin namespaces enable-stats topic <namespace>`
   - `pulsar-admin namespaces disable-stats consumer <namespace>`
   - also allow configuration of `producer`, `managed-ledger`, `managed-cursor`
   
   If the metric is disabled in `broker.conf`, then enabling it at a namespace level will _not_ override that. The namespace-level flags will default to enabled, so that it defaults to however `broker.conf` is set.
   
   **Describe alternatives you've considered**
   - This flag could also be configured at the tenant level. It doesn't seem like there are many tenant-level flags though.
   - The settings could be removed from `broker.conf` and only be configured at the namespace/tenant level. This may cause issues with backwards compatibility.
   
   **Additional context**
   Add any other context or screenshots about the feature request here.

   @gaozhangmin I do not intend to implement it with those alternatives.. they were simply alternatives to consider. I plan to implement it on the namespace level, without removing it from broker.conf

   Two doubles?
   1、Why you need config it at tenant level? 
   2、why you want remove from broker.conf?

   It is possible to ignore this metrics when get the metrics, like relabel in prometheus.
