LogicMonitor monitors Cassandra clusters using JMX. The following Datasources are available:
To use these in LogicMonitor, check your cassandra-env.sh file on the Cassandra server to see what you have configured for RMI authentication, including user, password and JMX port. Then add your Cassandra server as a monitored device.
Once added, locate this server on the Device tree and configure its properties as follows:
The nodetool utility is a command-line interface to access the data exposed by Cassandra via JMX. You can use this to verify that you can access performance data as follows:
nodetool -h host -p port -u user -pw password command
info - Print node informations (uptime, load, ...)
cfstats - Print statistics on column families
cfhistograms - Print statistic histograms for a given column family
compactionstats - Print statistics on compactions
netstats [host] - Print network information on provided host
tpstats - Print usage statistics of thread pools
See Apache Nodetool documentation for more details.
