A quick follow up question - If my node is configured with= Virtual Nodes and 256 tokens are assigned to it, how does the STATUS line = only show one token value? In this case the -12331...#.=A0

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

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

LOAD is the data size (sum of size of all the ColumnFamilies in a nod= e).

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 &q= uot;nodetool gossipinfo" command means?=A0

For example, what is the LOAD=A0#'s=A0= meaning or the SEVERITY=A0#?=A0My lo= ad is 91457.0 and SEVERITY: 22.448.= =A0Also, next to STATUS:NORMAL is a negative=A0#:=A0-123311655.... what d= oes that # mean?
