Overview

Xpand includes a general-purpose command line utility called clx for monitoring and managing a deployment.

The clx command must be executed on one of the Xpand nodes.

A single clx command is automatically processed in parallel on all Xpand nodes. It is located in the /opt/clustrix/bin/ directory.

The most useful commands are:

Command	Description
clx status	Displays the status, IP, and disk utilization of each node in the deployment.
clx cmd	Runs Linux commands in parallel on all nodes
clx logdump	Consolidates and filters Xpand logs so database issues can be researched and resolved.
clx dbstop	Stops Xpand on all nodes.
clx dbstart	Starts Xpand on all nodes.
clx dbrestart	Restarts Xpand on all nodes. (Use in lieu of dbstop and dbstart where applicable.)

Xpand clx utility also communicates with another critical element of the system called nanny. The nanny is a database deployment process that provides monitoring to ensure that all processes vital to Xpand are running. It is activated at system startup. If any critical Xpand component fails at any point, for any reason, nanny restarts it automatically.
