You can use Landscape to perform many common system administration tasks easily and automatically. Here are a few examples...
First, tag the machines you want to upgrade with a common tag, so you can use
the tag anytime you need to manage those computers as a group. If, for
instance, you want to upgrade all your desktop computers, you might want to
use "desktop" as a tag. Select your computers, then click on
COMPUTERS on the
top menu, and under that
INFO. In the box under
Tags:, enter the tag you want
to use and click the
If you've already tagged the computers, click on
COMPUTERS, then click on the
tag in the left column.
With your desktop computers selected, click on
Scroll to the bottom of the screen, where you'll see a
button. Click it to queue the upgrade tasks.
While the upgrade tasks are now in the queue, they will not be executed until
you approve them. To do so, next to
All, then click on the
Approve button at the bottom of the page.
The best way is to use upgrade profiles, which rely on access groups.
If an access group for your file servers already exists, simply click on its
name. If not, you must create an access group for them. To do so, click on
your account, then on
ACCESS GROUPS. Specify a name for your new access group
and click the
Save button. You must then add computers to the access group. To
do that, click on
COMPUTERS, then select all your file servers by using a tag,
if one exists, or a search, or by ticking them individually. Once all the
computers you want to add to the access group are tagged, click on the
menu choice, scroll down to the bottom section, choose the access group you
want from the drop-down list, then click the
Update access group button.
Once you have all your file servers in an access group you can create an
upgrade profile for them. Click on your account, then
PROFILES menu following
Upgrade profiles link, and then on the
Add upgrade profile link. Enter a
name for the new upgrade profile, choose the access group you wish to
associate with it, and specify the schedule on which the upgrades should run,
then click the
First find the package by clicking on
PACKAGES. Use the search
box at the top of the screen to find the package you want. Click the triangle
on the left of the listing line of the package you want to hold, which expands
the information for that package. Now click on the icon to the left of the
package name. A new icon with a lock replaces the old one, indicating that
this package is to be held during upgrades. Scroll to the bottom of the page
and click on the
Apply Changes button.
First select the computers whose information you want to see. One good way to
do so is to create a tag for that group of computers on my computers. Suppose
you want to monitor the size of the PostgreSQL database on your database
servers. Select the servers, then click on
COMPUTERS on the top menu, and
under that. In the box under
Tags:, enter a tag name, such as "db-server," and
Add button. Next, under your account, click on
CUSTOM GRAPHS, then
on the link to
Add custom graph. Enter a title, and in the
#! field, enter
/bin/sh to indicate a shell script. In the
Code section, enter the
commands necessary to create the data for the graph. For this example, the
command might be:
psql -tAc "select pg_database_size('postgres')"
For Run as user, enter postgres.
Fill in the
Y-axis title, then click the
Save button at the bottom of the
To view the graph, click on
MONITORING. You can select the
monitoring period from the drop-down box at the top of the window.
Manage them via a package profile.
