Network Monitor is a web-based monitoring solution for monitoring the performance and availability of a wide array of network assets. Network Monitor monitoring is agentless, meaning it does not install any software or files on monitored machines. Network Monitor comes with more than 40 built-in methods of monitoring. These methods can be extended using Lua scripts. Advanced Network Monitor features include multi-level alarm escalations, and the ability to configure alarm dependencies so that service providers only receive the most relevant alarms. All common operating systems are supported, including:
AIX (4.2 and above)
CentOS
Debian
Fedora
FreeBSD
HP-UX
Generic Linux
OpenBSD
OpenSUSE 10.2
Red Hat Enterprise Server
Solaris
Ubuntu
Windows
Terms and Concepts
Asset - An asset represents a computer or any other type of network device that can be addressed by an IP number or host name. An asset contains settings that are common to all monitors associated with that asset.
Monitor - A monitor tests a specific function in an asset. Most monitors are capable of collecting various statistical data for reporting purposes. When a monitor test fails consecutively a specified number of times, the monitor enters an Alarm state and executes a set of actions.
Group - A group is a "container node" for other nodes in the Network Monitor monitor tree. Typically groups represent a logical business unit.
Actions - One or more actions can executed when a monitor fails a consecutive number of tests. A set of recovery actions can be executed when a monitor recovers from an Alarm state.
Asset template - An asset template is used to assign a set of monitors to assets. Once assets are linked to an asset template, changes to the asset template are propagated to all the associated assets.
User group - A Network Monitor user group is a set of VSA users who can be notified or scheduled to be available for notification. Each asset in Network Monitor is assigned to one user group. When a monitor enters an Alarm state, notifications are typically sent to the asset's user group.
Credential - A credential is a username and password that authorizes access to a resource. Network Monitor stores credentials separately from the rest of the VSA. These credentials are used by monitors, actions and events to gain access to the appropriate resource when carrying out an operation.
Status Icons
A monitor is always in one specific state. This state is visualized in the Network Monitor interface with different colors. An asset or network always displays the most important state reported by any single monitor that belongs to it. Icons are listed below, ranked by their importance.
- The monitor is deactivated.
- This icon is used for assets and networks only. All monitors in the asset or network are deactivated, but the asset or network itself is active.
- The monitor has entered an alarm state.
- The monitor has failed one or more tests, but has not yet entered alarm state.
- The monitor is ok.
Additional guidelines:
Any state other than deactivated is an activated state.
An activated monitor tests its asset.
Deactivating any or all monitors of an asset does not deactivate the asset.
Deactivating any or all assets of a network does not deactivate their parent network.
Deactivating an asset deactivates all of its member monitors.
Deactivating a network deactivates all of its member assets.
Other Commonly Used Icons
- This icon displays the properties of an item and allows you to edit them.
- This icon indicates that the asset or monitor is inherited from a template. Monitors inherited from a template can not be edited directly.
- This icon indicates that the asset or monitor is in maintenance state and is not currently monitored.
- The monitor is deactivated.
- This icon is used for assets and networks only. All monitors in the asset or network are deactivated, but the asset or network itself is active.
- The monitor has entered an alarm state.
- The monitor has failed one or more tests, but has not yet entered alarm state.
- The monitor is ok.
- This icon displays the properties of an item and allows you to edit them.
- This icon indicates that the asset or monitor is inherited from a template. Monitors inherited from a template can not be edited directly.
- This icon indicates that the asset or monitor is in maintenance state and is not currently monitored.
- This icon displays a list of items.
- This icon displays a view of an item.
