Thanks Rob;
here is what I am looking for :
java -jar /home/user/jmxterm-1.0-alpha-4-uber.jar 10.30.41.52:7199 -O
org.apache.cassandra.internal:type=FlushWriter -A CurrentlyBlockedTask
It does Not work since there is something wrong with my syntax. However once
working, it would be scripted to connect to a large cluster from a single host
that would store the results into logs.
Any help with a single working example would greatly help. I am running
circles around this tool for a couple of hrs now.
ThanksJan

Would anyone on this forum know the exact syntax to connect to Cassandra Domain
using JMXterm ?
Here's an example from an old JIRA at my shop :
1. Download the jmxterm-1.0-alpha-4-uber.jar from
http://wiki.cyclopsgroup.org/jmxterm2. sudo java -jar
jmxterm-1.0-alpha-4-uber.jar # then within the tool:3. open <pid of cassandra
proc>4. bean org.apache.cassandra.db:type=StorageService # or whichever bean
you're looking for 5. run setLog4jLevel
org.apache.cassandra.db.index.keys.KeySearcher.java DEBUG # example of how to
set log level=Rob
