Introduction
Network Monitoring is the system That controls/monitors/supervises a network and notifies
the network administrator through e-mail or SMS.
Monitoring is a must for our company and every company that depends on its IT
infrastructure for any purposelike :
- Measuring Availability and performance
- Alerts are sent to the responsible personif any failure has been detected and also
informs administrator about unusual activities instantly.
- Results of the monitoring can be analysed and customised, also reports can be
generated.
- Help planning new investments and avoid expensive unused network components
through results that show how to strengthen the network by eliminting weak hardware,
failures, and security issues.

PRTG Network Monitorbenefits
- Discovers and assess network devices (PCs, Servers, Switches, Printers, etc.)
- Discovers unusual, suspicious, or malicious activity with devices or users.
- Monitors system usage (CPU loads, free memory, free disk, etc.)
- Monitors and alerts due to uptimes/downtimes or slow devices.
- Monitors and account bandwidth and network device usage.
- Monitors system health of various hardware devices.
- Monitors performance of databases as well as monitors databases directly.
- Monitors Email Servers.
- Monitors Virtual Servers.
- Monitors Cloud Services (Google mail, Google drive, ms.office 365, dropbox, icloud,
twitter, facebook, skype.)

Configuring PRTG Network Monitor
PRTG Network Monitor comes with three interfaces:
-Ajax web interface: through Web browser.
- Enterprise console (Windows GUI) on PRTG server.
- Mobile Web GUI.
For the first use of PRTG Network Monitor we should configurate it through « GURU »
configuration wizard.
- « Guru » configuration wizard Configuration
Configuring Administrator Account : configure default PRTG Admin « prtgadmin » and
domain E.mail address and password.

- Enter Administrator Credentials for Windows Systems
In order to use WMI (Windows Management Instrumentation), which is the standard
monitoring technology for Windows PCs and servers, PRTG needs to have administrator
access to our network, this conatins our domain name, domain admin username and
password.

- Enter Credentials for SNMP Based Network Devices
Most switches, routers and firewalls along with other network devices support SNMP
(Simple Network Management Protocol) for monitoring. PRTG needs the so-called
"community string" used on our network to access these devices.
- Enter Credentials for VMware/XenServer
PRTG supports monitoring of virtualization services, such as VMware and xin.
PRTG needs logins credentials if we are running VMware based virtualization (ESX/ESXi
3.5, 4.0, 5.0, and vCenter) or XenServer based virtualization.

- Enter Credentials for Linux/OSX Servers
PRTG can monitor PCs that run on various versions of Linux, Solaris, and Mac OS X, in
order to monitor computers that run on those operating systems, PRTG needs logins
credentials.

- Set up Monitoring for Internet Connection
PRTG can monitor our local LAN and internet connectivity. The following settings have
been taken from our LICT network configuration.
- Set up monitoring for Server in your LAN
PRTG has found the following servers in our LAN and will auto-discovers them. We can add
the DNS names or IP addresses of other servers.

- Set up Monitoring for Websites and Online Shops
PRTG can monitor websites and online shops using http by entering the URLs of the webites
that we want to monitor.

- Set up Monitoring for Cloud Services
If we use any of the cloud services (Google mail, Google drive, ms.office 365, dropbox,
icloud, twitter, facebook, skype), PRTG will set up a sensor for each service.
- Auto-Discover a Segment of Your Network
The automatic network discovery of PRTG can scan a segment of our network for devices.
Each device will be analyzed and sensors will be created according to the device type.

Startup MonitoringLICT Network
- Local probe
PRTG Network Monitor is installed on it. In LICT our PRTG server is: 192.168.9.199
- Groups
To add a group manually, select Devices | Add Group from the main menu, an assistant will
appear, and we should add group settings.
- Devices
The Add Device dialog appears when adding a new device to a group. It only shows the
setting fields that are imperative for creating the device, and we will not see all setting fields
in this dialog.

- Sensors
In PRTG we create “devices”, on those devices, we create “sensors”, we called them the
“basic monitoring elements”
Sensors are calssified according to:
- Their Functions: disponibility, bandwidth/traffic, speed, CPU use, memory use, network
infrastructure.
- Operating system of the target: Windows, Linux, Mac OS, SQL server, mail server.
- Technology used: Ping, SNMP, WMI, HTTP, NetFlow.
We can add sensors by click on “Add sensor”and choosewhich sensors we wants to add
from the sensors list.

We add (ping, Core Health free physical memory, System Health CPU Load, Disk Free, and
Network card connection).
Each sensorhas its configuration, and has a “Live Data”diagram.

PRTG gives also “2 days”, “30 days”, “365 days”and “Historic Data” which gives a
custom monitoring period of time as we want.
If sensoris down there is a “Notification”and we can configure it to send E.mail to PRTG
admins or users group.
Sensor has one or more “channels”in which it handles the actual monitoring data. In the
channel settings we can define how the data from the sensor's different channels shall be
displayed in graphs and tables. Additionally, the channel data can affect the sensor's status.

- LICT Devices and Groups
We have this groups in our system:
- Probe (192.168.9.199)
- Internet Connection(192.168.2.200, 192.168.40.3)
- Domain Controllers ( 192.168.3.1, 192.168.3.9)
- Exchange Servers ( 192.168.3.21, 192.168.3.22)
- Switches (192.168.2.197, 192.168.2.225, 192.168.2.230, 192.168.2.232,
192.168.2.234, 192.168.2.235, 192.168.2.236, 192.168.2.240, 192.168.2.241,
192.168.2.2242, 192.168.2.243, 192.168.2.244, 192.168.2.245, 192.168.2.247,
192.168.2.252, 192.168.2.253)
- Services Servers (192.168.3.23, 192.168.3.11, 192.168.33.8, 192.168.33.14,
192.168.33.60, 192.168.33.4, 192.168.33.9, 192.168.33.13, 192.168.33.10,
192.168.33.80)
All servers have been added with my credential as “majdk”, we will add all Servers to our
system and configure sensors that are needed in our network as soonas possible.

We have added most important sensors that affect our devices (SNMP sensors forhardware
configuration and WMI log events sensors for our servers).
For example we have added those sensors for all Servers:
(ping, system uptime, Memory, Disk Free),also add this sensors for Domain Controllers
(WMI EventLog) for all systemwarning logs, and for Exchange Servers we add (Active
User Count, Database Cache Size).

Reports
PRTG includes a powerful reporting engine, as well as scheduled report generation in
HTML and PDF format. So we can run reports on demand or on a regular basis (for
example, once a day). We can create reports for one single sensor, or we choosea range of
sensors we want to create a report for. It is also possible to create HTML reports for our
system configuration.
The content and layout of the report is controlled by the report template of our choice and is
the same for all sensors in a report.
PRTG is delivered with several pre-configured reports, we should select settings option to
configure reports, and settings include many options like:
- Template: this defines the overall look of our report and affects in which detail
(interval) monitoring data is included, there are templates that offer optional data
tables besides the graphs.
- Papersize:specify the paper size for which the report shall be formatted.
- Schedule:we can create reports for manual "on-demand use" or automatically every
hour, day, day of week, day of month or a specific date.
- Period: Specify which period is to be reported. We choosebetween daily, weekly,
monthly, quarterly or yearly reports.
- Access Rights:Set user group access rights for this object.

In our LICT network we create four templates for PRTG groups in our system as:
- Domain Controllers
- Exchange Servers
- Switches
- Services Servers
