Here is a snippet of what I see from one of my nodes: ubuntu@ip-10-0-2-163:~$ sudo tcpdump -i eth0 -v dst port 2003 -A | grep 'jvm' tcpdump: listening on eth0, link-type EN10MB (Ethernet), capture size 65535 bytes .Je..l>.pi.cassandra.us-east-1.cassy-node1.jvm.buffers..direct.capacity 762371494 1482960946 pi.cassandra.us-east-1.cassy-node1.jvm.buffers..direct.count 3054 1482960946 pi.cassandra.us-east-1.cassy-node1.jvm.buffers..direct.used 762371496 1482960946 pi.cassandra.us-east-1.cassy-node1.jvm.buffers..mapped.capacity 515226631134 1482960946 pi.cassandra.us-east-1.cassy-node1.jvm.buffers..mapped.count 45572 1482960946 pi.cassandra.us-east-1.cassy-node1.jvm.buffers..mapped.used 515319762610 1482960946 pi.cassandra.us-east-1.cassy-node1.jvm.fd.usage 0.00 1482960946 My metrics.yaml looks like this: graphite: - period: 60 timeunit: 'SECONDS' prefix: 'pi.cassandra.us-east-1.cassy-node1' hosts: - host: '#RELAY_HOST#' port: 2003 predicate: color: "white" useQualifiedName: true patterns: - "^org.+" - "^jvm.+" - "^java.lang.+" All the org.* metrics come through fine, and the jvm.fd.usage metric strangely comes through fine, too. The rest of the jvm.* metrics have this extra '.' character that causes them to not show up in graphite. Am I missing something silly here? Appreciate any help or suggestions. - Mike
