Setting the Error Log Collection Level
The error log (the HDLM manager log (dlmmgrn.log (n indicates a file
number from 1 to 16)) collection level can be set.
The following table lists and describes the values for the error log collection
level setting.
Table 3-72 Values for the Error Log Collection Level Setting
Value Description
0 No error logs are collected.
1 All information for errors of the "Error" level or higher is collected.
2 All information for errors of the "Warning" level or higher is
collected.
3 All information for errors of the "Information" level or higher is
collected.
4 All information for errors of the "Information" level or higher
(including maintenance information) is collected.
If an error occurs, you might have to change the collection level to 1 or
higher to collect any log information.
The higher this value is set, the more information that will be output. As the
amount of log information to be output increases, it will take less time to
overwrite the old error log information with the new information.
The following is an example of using a command to set the error log
collection level.
# /opt/DynamicLinkManager/bin/dlnkmgr set -ellv 2
