Monitoring Process Status (ps)
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/spread/sbin/spread
You should see one Vertica process and one Spread process on each node for common configurations. To monitor Administration Tools and connector processes:
$ ps aux | grep vertica
There can be many connection processes but only one Administration Tools process.
