IBM Tivoli Netcool-OMNIbus SNMP Writer Gateway

The IBM Tivoli Netcool-OMNIbus SNMP Writer Gateway connector acts as a trap receiver and orchestrator. With this connector it is possible to retrieve traps via SNMP or TCP (Smart-Serial). Furthermore the connector is able to create DVE's based on location or subdomain, which in terms show the events for the selected location/subdomain. It is also possible to forward the incoming events to other DMAs that use this connector via TCP based on the event domain configurations.

About

The IBM Tivoli Netcool-OMNIbus SNMP Writer Gateway device is a monitoring platform that is able to forward Netcool alerts. The alerts are forwarded as SNMP traps to an SNMP reader. This allows Tivoli Netcool-OMNIbus to generate traps that are forwarded to other management platforms such as DataMiner.

Installation and configuration

Creation

SNMP Main connection

This connector uses a Simple Network Management Protocol (SNMP) connection and requires the following input during element creation:

SNMP CONNECTION:

  • IP address/host: The polling IP of the device.

SNMP Settings:

  • Port number: The port of the connected device, by default 161.
  • Get community string: The community string used when reading values from the device, the default value is public.
  • Set community string: The community string used when setting values on the device, the default value is private.

Smart-Serial smart connection

This connector uses a serial connection and requires the following input during element creation:

SERIAL CONNECTION:

  • Direct connection:

    • Baudrate: Baudrate specified in the manual of the device, e.g. 9600.
    • Databits: Databits specified in the manual of the device, e.g. 7.
    • Stopbits: Stopbits specified in the manual of the device, e.g. 1.
    • Parity: Parity specified in the manual of the device, e.g. No.
    • FlowControl: FlowControl specified in the manual of the device, e.g. No.

  • Interface connection:

    • IP address/host: The polling IP of the device.
    • IP port: The IP port of the device.
    • Bus address: The bus address of the device.

Usage

General

The "General" page contains the Orchestrator Table. For every incoming event the domain of the event is checked and if it is not present in the Orchestrator table it will get added to the table. Each domain in the Orchestrator table has a matching function. The functions are explained in following table. It is also possible to manually add domains and functions by right-clicking the Orchestrator table and selecting "Add Domain(s)".

Function Description
Not Configured (Default) When an incoming event has a Domain value which is not already registered, the value gets added to the orchestrator table with the default function of not configured. When a domain is not configured, all incoming events for that domain are stored into a configuration buffer until the domain gets configured.
Show per Subdomain Creates DVEs for this domain based on the subdomain value of the incoming events.
Show per Location Creates DVEs for this domain based on the location value of the incoming events.
Forward Forward the incoming event via a TCP connection with the destination that is specified in the IP:Port column of the orchestrator table. If the connection fails, the events are stored in the connectivity buffer. After a configured amount of minutes, the events in the connectivity buffer are re-forwarded.
Discard Drops the incoming events for this domain.

DVE Table

When for a certain domain the functions "Show per Subdomain" or "Show per Location" are selected, DVE's will be created for these traps based on the selected function. On the "DVE Tables" there is a table "Sub Domain Table" which list all existing DVEs based on subdomain and a table "Location Table" which lists all the DVEs based on location. It it also possible to add DVEs manually by right-clicking one of the table and selecting Add Subdomain[or Location].

Events

On the events page the "Netcool.Events Table" is displayed. This table contains all the netcool event entries that are destined for this DMA.

Configuration

On the Configuration page it is possible to configure the Community String that has to be match for incoming traps via Smart-Serial connection. Furthermore the buffer configurations are located on this page. There are two buffers, the connectivity buffer and the configuration buffer. For each buffer it is possible to specify the Buffer Size Limit which determines the maximum number of entries in the buffer and The Buffer Time Limit which is the maximum amount of time that an entry can stay in the buffer. Also the amount of entries in both buffers are shown on the Configuration page. For the Connectivity Buffer it is also possible to configure the Forward Retry Time. This is the time interval for executing retries to forward the content of the connectivity buffer.
