Hello, We use the output from the AllEndpointStates attribute of the org.apache.cassandra.net:type=FailureDetector MBean via MX4J for basic monitoring/sanity checking. I've found that the output changed between 2.1.9 and 2.1.10; there is now additional info for some of the keys (DC, RELEASE_VERSION, STATUS, etc.)
Is this maybe due to CASSANDRA-10330 <https://issues.apache.org/jira/browse/CASSANDRA-10330>? I perused the changelog, JIRA, and the git repo and didn't see anything else that really stuck out at me. Is the new output documented somewhere? *Example 2.1.9 output:* ["DC:us-west-2", "HOST_ID:ed17c00e-2015-4b0f-9ee1-fa96e6c2ff8c", "LOAD:3525337.0", "NET_VERSION:8", "RACK:2a", "RELEASE_VERSION:2.1.9", "RPC_ADDRESS:1.2.3.4", "SCHEMA:b3a65c2a-8955-30f3-b403-54db3260f777", "SEVERITY:0.0", "STATUS:NORMAL,-1012622047045121026", "generation:1441736600", "heartbeat:7847815"] *Example 2.1.10 output:* ["DC:6:us-east", "HOST_ID:2:8c8ed6f6-84d9-494d-a6c3-a9701cefe347", "LOAD:537977:1.45221778E8", "NET_VERSION:1:8", "RACK:8:1b", "RELEASE_VERSION:4:2.1.10", "RPC_ADDRESS:3:1.2.3.4", "SCHEMA:10:d58b9de5-9e25-3128-b07e-dfa0b2568ae8", "SEVERITY:538103:0.0", "STATUS:14:NORMAL,-1022178689192707266", "TOKENS:13:<hidden>", "generation:1444146690", "heartbeat:538104"] Thanks!
