Motivation

I want to get the load information of all brokers and currently I can only do it by a loop call org.apache.pulsar.client.admin.BrokerStats#getLoadReport

Also, I need to save additional IP information for all brokers.

Solution

Add a new admin API getAllLoadReport() to get information about all brokers.

Alternatives

At the moment I can think of two implementation options:

• Internally call the getLoadReport API of all brokers to aggregate their data.
• Refer to the org.apache.pulsar.testclient.BrokerMonitor implementation to get information from ZooKeeper. https://github.com/apache/pulsar/blob/002fa49692ff4b8b038bf2edeeb3b32ed218e64f/pulsar-testclient/src/main/java/org/apache/pulsar/testclient/BrokerMonitor.java#L51-L55

Any better suggestions?

Anything else?

@Technoboy- @codelipenghui do we agree on this direction? Or it's just won't do.

I can imagine that "loop call org.apache.pulsar.client.admin.BrokerStats#getLoadReport" doesn't sound too bad.

Ah, sorry for the late response. It's ok to add this kind of the API.

Refer to the org.apache.pulsar.testclient.BrokerMonitor implementation to get information from ZooKeeper.

Looks better
