Question about info returned from 'nodetool gossipinfo'
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?

Not sure about vnodes setup. looks like the output shows only the first token. if you are looking for all tokens assigned, 'nodetool info -T' might help.

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...#.

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.
