CSM Web Interface Main Page Help
Introduction
CSM (Cluster Systems Management) assists
an administrator in managing a whole set
of Linux machines. With this software, an
administrator is able to more easily set
up and maintain the machines via features
like parallel install, hardware control,
configuration file management, event monitoring,
etc.
Page Layout
Each page of the CSM web interface typically contains:
- The Webmin header at the top.
- Links to the main CSM tasks in the grey bar.
- Action buttons on the left that apply to the content area.
- The content area that contains the information and options for this task.
- Hints for using this page effectively. Be sure to read these on each
page.
The main page of the CSM web interface shows a list of nodes and some basic
information and monitoring status for each one. You can change which
nodes are displayed by choosing a different node group in the Which Nodes: drop down box. (To create more choices in this drop down box, add
node groups using the "Edit Groups" button.) Or you can
specify a node range to display a list of nodes for which you don't have
a node group defined. Currently, a node range can be a single
node name or a range in the form "node1-node5", where node1 and
node5 are actual node names.
To perform an operation against one or more nodes, select the check box
next to each desired node and click on one of the buttons to the left of
the node table.
Action Buttons
The action buttons on the left allow you to do the following operations
against specific, selected, nodes:
- Properties - show the attributes of the node(s), including the attributes from the
ManagedNode table and some actual values retrieved from the node. You
can also change the ManagedNode attributes from this page. You can
run this action against multiple nodes if you want to, for example, set
an attribute the same for all of those nodes.
- Update - take any changes of the node definition on the management server and apply them to the node. This includes new levels of CSM or other RPMs, new/changed configuration files, or updated attributes in the ManagedNode table. You can also query what changes need to be applied, without actually applying them.
- Run Cmd - use dsh to run a command in parallel on the nodes and sort the output.
- Copy Files - copy files 1 time from the management server to nodes, or from the nodes
to the management server. This requires dcp from the csm.ect RPM
or from CSM 1.3.3. If you want files copied any time they change,
consider using the Config File Mgmt task.
- HW Ctrl - control or query the hardware using the service processor. This
includes powering on or off, rebooting, querying hardware status/information,
and collecting MAC addresses.
- RSA/MM - enter the web interface for the hardware control point that this node
is attached to. If your hardware control points are on a private
network, you won't be able to reach them from the browser on your desktop.
In the situation, this option will only work if you are running the
browser from your CSM management server.
- PerfMon - monitor the peformance of the selected nodes in real time, or get a
history graph of their performance.
- Webmin - bring up the webmin interface for the specific selected node. This
only works for a single node and if webmin has been installed on that node
and the node network is reachable from where you are running your browser.
- Diagnose - run the probe manager to check out the software on the node to determine why it isn't working correctly.
- Install - reinstall the node with a specified level of the OS and CSM.
- Remove - remove the node from the CSM cluster.
CSM Tasks
The main CSM tasks are listed across the top (just below the Webmin header).
The current task is highlighted. These links allow you to do
different operations:
- Define Node - add a new node or nodes into the CSM cluster.
- Edit Groups - add, modify, or delete node groups. Node groups allow you to display a set of nodes and do operations against the whole set of nodes.
- Monitor - define conditions in the system that should be monitored and define
responses when those conditions occur. Also monitor the current status
of the conditions, and view the AuditLog.
- Config File Mgmt - edit or set up configuration files (e.g. /etc files)
and push them out to the nodes.
- Software Maint - download new RPMs to the management server and install them or
push them out to the nodes.
- Diagnose MS - many links and operations to use when you are trying to figure out why
the management server is not working correctly.
- CSM Config - view/set the global settings for the CSM cluster.
Webmin Header
The top part of each page contains some useful links:
- Webmin Index - goes to the main page of the Webmin interface to allow you to do standard system management operations to the CSM management server machine.
- Help - the help for that particular page.
- Module Config - set preferences for the CSM web interface.
- Send suggestions... - the developers of this CSM web interface welcome any suggestions to
have to make it more useful.
