Plugins and Drivers

 Top  Previous  Next

Network Manager is actually a set of plugins and drivers, supporting monitoring and management of network devices. Some of its features are inherited from the basic AggreGate device management solution:

•SNMP Device Driver for collecting data from networked devices using Simple Network Management Protocol and receiving SNMP traps.
•IP Host Device Driver for monitoring servers, applications, and services.
•Database Device Driver for monitoring database servers and executing arbitrary SQL queries.
•Device Discovery plugin for performing network discovery using SNMP, ICMP Ping, TCP port scanning and other methods.

At the same time AggreGate Network Manager includes a number of specific plugins and drivers as covered below.

Syslog Server Plugin

Syslog Server Plugin provides reception and processing of Syslog messages.

On receiving a Syslog message, the Syslog Server fires a corresponding AggreGate event. The level of the event is mapped from the Syslog message severity according to the specified settings. Other data associated with the original message, such as host, severity, facility, message and timestamp (refer to RFC 5424 for details on Syslog messages), are also included in the event.

Syslog Server Plugin Configuration

Syslog Server plugin is configured using standard Driver/Plugin Configuration Context in Drivers/Plugins Configuration Context. The Syslog Server Configuration includes the following settings:

Property

Description

Enabled

Enables/disables syslog messages monitoring.

Syslog Protocol

Specifies the protocol (TCP or UDP) to receive Syslog messages by.

Syslog Port

Specifies port to receive syslog messages at.

Severity Conversion Table

Syslog Severity (according to RFC 5424) to AggreGate Level mapping.

LinkServer should be restarted for the changes take effect.

Network Management Extensions Plugin

Network Management Extensions plugin includes necessary software components for creating and configuring AggreGate parts used as network management tools, including: alerts, queries and reports, charts, widgets, and actions.

Local File Driver
