in .Log. Archiving has the advantage of decreasing the size of the log tables, which enables the
shownode metrics command to run more quickly.
You must be superuser to use this command.
Use the --archive archive-file option to specify the file to which the sensor data will be
archived.
The --tmpdir directory option lets you assign a temporary directory for use while archiving.
You can retain previous archives with the --keep n option.
You can specify a time parameter with the managedb archive command; sensor data older
than the time parameter is purged. The time parameter (which can also be used with the
managedb purge command) is expressed in terms of hours, days, weeks, and years, as shown
in the following table:
Archive (or Purge) All sensor Data:Time Parameter
Regardless of age (default)
now
Older than n hoursnh
Older than n daysnd
Older than n weeksnw
Older than n yearsny
The following example archives sensor data older than four days to an archive file named
arfile_tuesday in the current directory:
# managedb archive --archive ./arfile_tuesday 4d
Be sure to archive the configuration and management database on a regular basis (at least monthly)
to save disk space.
For more information on the managedb command, see managedb(8).
The archive.cron script enables you to automate the process of archiving sensor data from
the CMDB. For more information on this script, see archive.cron(4).
6.7 Restoring the Sensor Data from an Archive File
You can restore sensor data archived in an archive file to the configuration and management
database with the managedb restore --archive command.
You must be superuser to use this command.
Archive files are created with the managedb archive command. See “Archiving Sensor Data
from the Configuration Database” (page 83).
The following example restores the sensor data archived in an archive file named
arfile_tuesday in the current directory:
# managedb restore --archive ./arfile_tuesday
For more information, see managedb(8).
6.8 Purging Sensor Data from the Configuration and Management
Database
Use the managedb purge command to remove sensor data from the configuration and
management database without archiving them.
You must be superuser to use this command.
You can specify a time parameter with the managedb purge command; sensor data older than
the time parameter is purged. The time parameter is the same as for the managedb archive
