SNMP Importance
Why SNMP is Important in today’s SCADA
systems
SNMP Data Mining Features
SNMP-to-the-Core
• Fully integrated into ICONICS FrameWorX
GUI developed around user needs
Full exploration of SNMP
Auto-detection of Device Types with fancy
recognizable ICONs
MIB parser with no limits on the number of
OIDs that can be imported
SNMP Data Mining Features
Auto-discovery of Managed Devices
• Possible to scan whole networks with one
command
• Configurable time-out for the Ping function
• Multi-threaded design provides fast response
Supports the ability to use SNMP data as tags
(just as you would use OPC DA tags)
SNMP Key Components
Three key components:
• Managed devices (network elements)
- Network node that contains an SNMP agent and that
resides on a managed network. Managed devices
collect and store management information and make
this information available to NMSs using SNMP.
Managed devices, sometimes called network elements,
can be routers and access servers, switches and
bridges, hubs, computer hosts, or printers
• Agents
- Network-management software module that resides in
a managed device. An agent has local knowledge of
management information and translates that
information into a form compatible with SNMP.
• Network-management system (NMS)
- An NMS executes applications that monitor and control
managed devices. One or more NMSs must exist on
any managed network.
SNMP Protocol - OIDs
OID – Object Identifier
The “OPC Tagname” in the IT World
Each Object (piece of information) is identified by a
series of numbers

What is a MIB?
MIB – Management Information Base
• ASCII text file that describes an SNMP Network
Element as a list of data objects
• Translates numeric strings into Human
Readable text
• Provides the data type of each OID
What the ICO MIB Looks Like

SNMP Basic Commands
Read
• Used to Monitor Managed Devices
Write
• Used to Control Managed Devices
Trap
• Used by Managed Devices to asynchronously
report (report by exception) events

Exploration –
Enter beginning

Options to:
- Retrieve DNS Name
- Cache the MIB
Launch the
Explorer
SNMP Explorer
GUI similar to
the Unified Data
Browser’s GUI
Easy to recognize the
Device types because
of the ICONs
Possible to explore the
Objects supported by
each discovered device
(using the MIB)
Human Readable names are
provided if the MIB for the device
is contained In the database
(otherwise OID number is displayed)
If the SNMP root is selected
In the left pane, the right
Pane will list the devices and their
Well-known types
SNMP Explorer Part 2
Selected Values
Are moved to the
Upper pane
(like UDB)
When bottom of tree
Reached, shows the
Leaves, with data types
(if MIB is present)
Tooltip provides

SNMP Tag Browsing
SNMP Tab in the Unified Data Browser
Shows ICONs and Human Read-able descriptions
SNMP Agents
SNMP Agents
• Microsoft SNMP Agent plugins
• Expose useful data through SNMP
protocol
• Data available to all SNMP NMS
- Open View
- Tivoli
- Other agents
• MIB files available for every agent
SNMP Simulator Agent
SNMP Simluator Agent
• Simulates Network data
-
Printer (ink level, paper level, alarms, …)
Router (routing table, …)
Computer (HD usage, memory usage)
Simulated signals (sin, ramp, …)
Other (fans, tempeature)
• Used for GenDemo displays
SNMP MonitorWorX Agent
SNMP MonitorWorX Agent
• Almost all MWX information exposed
-
Site key
Processes running
Licensing information
Redundancy
• GraphWorX displays with MWX data
- MWX data available via WebHMI all over
the network
The world of SNMP
Third party Management Systems
• SNMP protocol is a standard
• Information available to all SNMP applications
- MIB Files specify the data structure to the NMS
- SNMP agents send the data
- Nothing else is needed
• MonitorWorX management available on
existing infrastructures
