Chapter2 : Lab 2.5.3 Investigating Network Monitoring Software

Step 1: SNMP overview

Simple Network Management Protocol is a common network management protocol. The protocol enables

network administrators to gather data about the network and corresponding devices. SNMP management

system software is available in tools such as CiscoWorks. SNMP management agent software is often

embedded in operating systems on servers, routers, and switches.

SNMP has four main components:

• Management station

• Management agents

• Management Information Base (MIB)

• Network management protocol

Descriptions of SNMP are available at:

http://www.cisco.com/univercd/cc/td/doc/cisintwk/ito_doc/snmp.htm

http://www.protocols.com/pbook/tcpip9.htm#SNMP

As part of a network management system, SNMP tools can respond to network errors or failures in several ways. Generally, when a network fault occurs, or when predefined thresholds are met; the SNMP tools can react by:

• Sending an alert on the network

• Sending a message to a pager

• Sending an email to an administrator

The FilmCompany is required to maintain a specified level of network service to meet its StadiumCompany contract obligations. They need to purchase network management software that enables them to monitor and manage the new upgraded network.

Step 2: Search for SNMP monitoring programs

a. Using a computer with Internet access, use a web browser to search for examples of SNMP monitoring programs. Use search terms such as:

• SNMP reporting

• SNMP notification

• SNMP monitoring

b. List other appropriate search terms.

c. Note and compare the features of a number of the monitoring programs found.

Step 3: Example SNMP program

An example SNMP monitoring program is Plixer Denika v7.

a. Go to the website for this program at http://www.plixer.com/products/denika.php.

b. List the type of reports that this program can generate.

Laporan Pemanfaatan
Laporan Level Layanan
Laporan TOPn
Laporan Terjadwal

c. Read the details for each type of report. Select the report type that would be most applicable to

ensure a problem with the performance of the link carrying real time video data from the

StadiumCompany to FilmCompany was addressed as soon as possible. Summarize the features of

this reporting provided by this program.

Step 4: Reflection

Consider and discuss the organizational or business support necessary to make best use of network

monitoring programs with event-triggered notification features.

Ambang batas peristiwa dan kondisi yang memicu pemberitahuan harus disetel sehingga tidak perlu notifikasi tidak terkirim, tapi kondisi kritis dilaporkan dan pemberitahuan dikirim. Karyawan Perseroan yang harus diberitahukan baik secara teknis mampu mengatasi masalah ini dan tersedia untuk melakukannya ketika diberitahu. Hal ini akan membutuhkan tindakan perusahaan untuk memastikan bahwa staf terlatih dalam merespon proses, dalam keterampilan teknis, dan dalam mengatasi masalah dan pemecahan masalah. Daftar nama karyawan dan alokasi tugas perlu mempertimbangkan masalah ini.
