the output of "nodetool gossipinfo" are the application states of each endpoint/node in the cluster that are exchanged b/w the nodes during gossiping.

"Severity" is basically a measure of compaction activity/events in a node ( see https://issues.apache.org/jira/browse/CASSANDRA-3722 for the details on how it is used by dynamic snitching).

LOAD is the data size (sum of size of all the ColumnFamilies in a node).

the number next to the STATUS line is the token assigned to that node. you seem to be using Murmur3Partitioner, which has negative tokens.

Hi,

Does anyone know what the information that comes from the "nodetool gossipinfo" command means? 

For example, what is the LOAD #'s meaning or the SEVERITY #? My load is 91457.0 and SEVERITY: 22.448. Also, next to STATUS:NORMAL is a negative #: -123311655.... what does that # mean?
