Monitoring Processes

You can use ps to monitor the database and Spread processes running on each node in the cluster. For example:

$ ps aux | grep /opt/Vertica/bin/Vertica

$ ps aux | grep /opt/Vertica/sbin/spread

You should see exactly one Vertica process and exactly one Spread process on each node. To monitor Administration Tools and connector processes:

$ ps aux | grep Vertica

There may be many connection processes but at most one Administration Tools process.
