Setting Log Storage Limits
You can specify the number of days that NSM stores logs; as well as purge or archive a
specified log based on the following configurable criteria:
• “Date Limits” on page 795
• System-Wide Retention Policy
•
Obsolete Logs
•
Required Disk Space
Date Limits
If you use a date to purge or archive logs, the limit is based only on the calendar date.
System-wide Retention Policy
The system administrator can specify the maximum number of days the system stores
logs. One configuration throughout NSM is permitted at a time. Users can specify how
the retention policy is triggered and when it is scheduled.
Obsolete Logs
As logs become obsolete, the user can archive before the system purges the logs. You
have the option of purging the logs directly or archiving them first. If you select the archive
option, NSM archives all the logs from the selected date.
Required Disk Space
After you define the number of logs and the number of days you want archived, NSM
estimates the disk space required for storing the logs. In calculating the estimated required
disk space, NSM uses the average size of logs per day and indicates to the user how the
estimate was reached or if there was not data available to provide an estimate.
Archive Location
The location of the archive is user-configurable from the Disk and Log Management
dialog box. The options are Local and Remote :
•
Local —To archive logs locally, specify the directory location for file storage in the
Archive Location field.
• Remote —To archive logs remotely, specify the IP address, username, password, and
the protocol (scp and sftp). The path on the remote server is stored in the user’s
preferences. SCP and SFTP work only with trusted hosts.
File Name
One log archive location is applicable throughout the system. The following naming
convention is used for storing log files:
YYYYMMDD_<No>.tar.gz
