Hi all, We have developed a new Pulsar web UI - pulsar-manager, aiming at supporting managing Pulsar clusters running in different environments (on-premise data centers, cloud, and so on). We’d like to contribute the project back to the Pulsar community.
--- ## Motivation Currently, Pulsar has a monitoring tool - [Pulsar Dashboard]( [ http://pulsar.apache.org/docs/en/administration-dashboard/](http://pulsar.apache.org/docs/en/administration-dashboard/) ). However, it only focuses on the simple monitoring of Pulsar - collecting and displaying information such as statistics of tenants, namespaces, topics, subscriptions, and so on. It doesn’t provide any management operations such as add, delete and update tenants, namespaces, topics, and so on. When the scale of Pulsar cluster increases or the number of clusters grows, using `pulsar-admin` to manage Pulsar can not satisfy demands. Therefore, Pulsar needs a simple and easy-to-use management console for administrators. Pulsar Manager is a web-based GUI management and monitoring tool that helps administrators and users manage and monitor tenants, namespaces, topics, subscriptions, brokers, clusters, and so on, and supports dynamic configuration of multiple environments. ## Features Pulsar manager provides two main features: management and monitoring. ### Management 1. Environment : (operations on the environment) Create / Delete / Update / List / Get 2. Cluster : (operations on clusters) Create / Delete / Update / List / Get 3. Brokers : (operations on brokers) Heartbeat / Unload 4. Tenants: Create / Delete / Update / List 5. Namespaces: Create / Delete / List Manage Namespace Policy Unload Operations on Namespace Bundles 6. Topics Create / Delete / List Unload / Terminate / Offload / Compact Topic Details 7. Subscriptions Create / Delete / List Reset Cursor / Skip / Clear backlog / Unsubscribe 8. Namespace Isolation Policies Create / Delete / Update / Get / List 9. Failure Domains Create / Delete / Update / Get / List ### Monitoring: (display *aggregated* stats at different levels) 1. Tenants List the total number of namespaces per tenant (both aggregated and per-cluster basis) 2. Namespaces List the total number of topics per namespace List the aggregated stats per namespace (such as rate-in, rate-out, throughput-in, and throughput-out) List the distributions of namespace bundles 3. Topics List the total number of partitions per topic List the aggregated stats per topic (such as rate-in, rate-out, throughput-in, and throughput-out) Detailed stats per topic partition Detailed stats of storage per topic partition Detailed stats of subscription per topic and per partition Detailed stats of producers Detailed stats of consumers The detailed design proposal is in [ https://docs.google.com/document/d/1C3meaHJzxX9wGDWQx-dC1b20yGeKsQtbwNiYuxZgOCE/edit#](https://docs.google.com/document/d/1C3meaHJzxX9wGDWQx-dC1b20yGeKsQtbwNiYuxZgOCE/edit#) Looking forward to any feedback. Thanks, Guangning
