nodetool getcompactionthroughput

Where is the cassandra-env.sh file?

The location of the cassandra-env.sh file depends on the type of installation:

Installation Type Location

Package installations + Installer-Services installations

/etc/dse/cassandra/cassandra-env.sh

Tarball installations + Installer-No Services installations

<installation_location>/resources/cassandra/conf/cassandra-env.sh

Print the throughput cap in megabytes (MB) per second for compaction in the system.

Synopsis

nodetool [options] getcompactionthroughput

Tarball and Installer No-Services path:

<installation_location>/resources/cassandra/bin
Connection options
Short Long Description

-h

--host

Hostname or IP address.

-p

--port

Port number.

-pwf

--password-file

Password file path.

-pw

--password

Password.

-u

Remote JMX agent username.

--

Separates an option from an argument that could be mistaken for an option.

  • For tarball installations, execute the command from the <installation_location>/bin directory.

  • If a username and password for RMI authentication are set explicitly in the cassandra-env.sh file for the host, then you must specify credentials.

  • nodetool getcompactionthroughput operates on a single node in the cluster if -h is not used to identify one or more other nodes. If the node from which you issue the command is the intended target, you do not need the -h option to identify the target; otherwise, for remote invocation, identify the target node, or nodes, using -h.

Description

The nodetool getcompactionthroughput command prints the current compaction throughput.

Examples

 $ nodetool -u username -pw password getcompactionthroughput
