A policy is a set of configuration information that helps to
automate network and system administration. Using HPOM,
administrators can deploy policies on various computers to provide
consistent, automated administration across a network.
Every policy belongs to one of several policy types. A
policy type is a set of rules that defines what a policy can do. An
understanding of the policy types helps you choose the right policy
for the management problem that you want to solve. The currently
available policy types can be grouped into the following
categories:
After you have decided what kind of policy you want to write,
see Quick Start: How to create a
policy to learn how to create and deploy the policy.
Monitor policy types
Logfile Entry policy type
This policy type monitors entries in a text or binary log file
and responds when text that you choose appears in the log file.
Choose this policy type if you want to monitor entries in a log
file.
Measurement Threshold policy type
This policy type evaluates performance data and responds if the
data does not remain within acceptable levels. Choose this policy
type if you want to monitor parameters that are constantly
changing, such as CPU load, disk space, number of running
processes, and so on.
Open Message Interface policy type
This policy type monitors and responds to messages
that are sent from the HP Operations process opcmsg. This
process allows scripts or programs to generate HP Operations
messages and send them directly to the management
server. Use this policy if you want to filter these messages
before they are sent to the management server.
Process-monitor policy type
This policy type monitors services and policies which are
running on the managed
node and sends a message when the state of the service or the
process changes. You can define the status to monitor and the
action to
take should the status change. Choose this policy type if you want
to monitor the status of Windows services or processes, which are
running on the managed node.
SNMP Interceptor policy type
This policy type monitors SNMP
events, and responds when a character pattern that you choose is
found in an SNMP message. Choose this policy type if you want to
monitor network components that send SNMP messages
Windows Event Log policy type
This policy type monitors entries in a Windows event log and
responds when a character pattern that you choose appears in the
event log. Choose this policy type if want to monitor entries in a
Windows event log.
Windows Management Interface policy type
This policy type monitors the properties of WMI classes and
instances, and responds when a property matches a value you select,
or when an instance you select is created. Choose this policy type
if you want to monitor objects that provide WMI information.
Windows Service Monitor policy type
This policy type monitors the Windows services and processes
which are running on the managed
node and sends a message when the state of the service or the
process changes. You can define the status to monitor and the
action to
take should the status change. Choose this policy type if you want
to monitor the status of Windows services or processes, which are
running on the managed node.
Node configuration policy
types
ConfigFile policy type
This policy type provides a consistent way to configure managed
node instrumentation. It is used by Smart Plug-ins (SPIs) to
enhance the management capabilities for specific enterprise
applications like SAP and Microsoft Exchange. ConfigFile policies
indirectly perform monitoring through another instrumentation
component.
Flexible Management policy type
This policy type is used to configure agent-based flexible
management scenarios on the managed node. You can configure the
node to send messages to different management servers based on the
type of problem, or send messages to different servers based on the
time of day.
NOTE:
You can deploy only one policy of this type to a node.
Node Info policy type
This policy type allows you to configure some aspects of agent
behavior, for example, buffer sizes, IP addresses, and port numbers
for client-server communication.
Scheduled Task policy type
This policy type allows you to schedule commands to run on
managed nodes, and will send a message to the management server to
indicate the success or failure of the command. Use this policy if
you want to run commands on one or more managed nodes—either once
or according to a specific schedule.
Service Auto-Discovery policy type
Discovery policies are supplied by Smart Plug-ins (SPIs) to
discover services in your managed environment and display them on a
service map. Usually there is no need to modify the SPI
auto-discovery policy. However, certain SPIs may require that you
configure this policy by adding parameter data such as a user name
or password to allow access and discovery of specific applications
on a managed node.
Server configuration policy
types
Remote Action Security policy type
By default, any node can send a message with a remote automatic
action, and the management server runs that action on the remote
node. However, you can configure a management server to allow or
deny remote automatic action requests. You do this using a remote
action security policy. Remote Action Security policies are
deployed to the management server.
Server-based Flexible Management policy type
Server-based flexible management enables you to forward
messages, message operations, and action responses from one
management server to another. Server-based flexible management
policies are deployed to the management server.
Server-based MSI policy type
The server-based Message Stream Interface (MSI) enables
programs external to the HPOM message and action server to read and
change incoming messages before they are stored in the HPOM
database. Server-based MSI policies are deployed to the management
server.
