Access EXAsupport
EXAsupport is available on every database node. To access EXAsupport, log into the database access node using Exasol Deployment Tool (c4).
To get started with EXAsupport, view the EXAsupport help.
The user executing the EXAsupport commands is the user who is logged into the node, which is typically root
. There are no extra authentication steps when using EXAsupport in this way.

Check Free Disk Space
Logs can become very large. Before you generate a log, determine the estimated size of the log and ensure you have enough free disk space on the node to store it.
-
To estimate the resulting log file size, add the Estimate parameter (
-m
) to the end of the EXAsupport command that you want to run. EXAsupport will then perform a dry run of the command and return an estimated size for the result. For example: -
To check your free disk space on the node that will store the log, run the command
df
(disk free) with the option-h
(human readable). For example:[root@n10 ~]# df -h
