This patch uses the estimated latency that was added to the column family metrics to get the recent and estimated latency. It follows the same logic as origin does to call the logic in metrics. The following method implementation will be added: getMemtableColumnsCount getRecentSSTablesPerReadHistogram getSSTablesPerReadHistogram getLifetimeReadLatencyHistogramMicros getRecentReadLatencyHistogramMicros getRecentReadLatencyMicros getLifetimeWriteLatencyHistogramMicros getRecentWriteLatencyHistogramMicros getRecentWriteLatencyMicros getRangeCount getTotalRangeLatencyMicros getLifetimeRangeLatencyHistogramMicros getRecentRangeLatencyHistogramMicros getRecentRangeLatencyMicros Signed-off-by: Amnon Heiman <amnon@cloudius-systems.com>
Urchin JMX Interface
This is the JMX interface for urchin.
Compile
To compile do:
mvn install
Run
The maven will create an uber-jar with all dependency under the target directory. You should run it with the remote jmx enable so the nodetool will be able to connect to it.
java -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=7199 -Dcom.sun.management.jmxremote.local.only=false -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -jar target/urchin-mbean-1.0.jar
Setting IP and Port
By default the the JMX would connect to a node on the localhost on port 10000.
The jmx API uses the system properties to set the IP address and Port. To change the ip address use the apiaddress property (e.g. -Dapiaddress=1.1.1.1) To change the port use the apiport (e.g. -Dapiport=10001)
