The Unrealized Role of Monitoring & Alerting w/ Jason HandSonatype
In today’s world, a company must be a “Learning Organization” in order to be successful and innovative. Learning from both failure and success, in order to implement small incremental improvements is critical. But until you implement and apply new information, you haven’t truly “learned” anything and you certainly haven’t improved.
According to the 2015 Monitoring Survey, most companies leverage metrics from monitoring and logging purely for performance analytics and trending. If high availability and reliability are important, they also leverage metrics to alert on fault and anomaly detection. Despite these “best practices”, the metrics are primarily only used as context to keep things “running” or return them back to “normal” if there’s a problem. Rarely is that data used as a method to identify areas of improvement once services have been restored. When an outage occurs to your system, you will absolutely repair and restore services as best you know how, but are you paying attention to the data from the recovery efforts? What were operators seeing during diagnosis and remediation? What were their actions? What was going on with everyone, including conversations? A step-by-step replay of exactly what took place during that outage.
This “old-view” perspective on the purpose of monitoring, logging, and alerting leaves the full value of metrics unrealized. It fails to address what’s important to the overall business objective and it lacks any hope of seeking out innovation or disruption of the status quo.
This talk will illustrate how to identify if your company is making the best use of metrics and ways to not only learn from failure, but to become a “Learning Company”.

Next generation tech trend for global critical communication standardYi-Hsueh Tsai
Today commercial cellular networks and dedicated public safety systems are two separate technology families for providing terrestrial wide-area wireless communications. With NPSTC, TCCA and ETSI Technical Committee TETRA supporting LTE there is now a clear global consensus that it will be the global standard for next generation broadband public safety networks. In order to provide the best service to both communities, they are establishing common technical standards offers advantages to both communities. Work underway in Release 12 of 3GPP LTE standards will enhance LTE to meet public safety application requirements. The public safety community gets access to the economic and technical advantages generated by the scale of commercial cellular networks, and the commercial cellular community gets the opportunity to address parts of the public safety market as well as gaining enhancements to their systems that have interesting applications to consumers and businesses. Developing the ecosystem also requires each country and user community to develop the right government policy, commercial environment and spectrum plan. Those plans and works are undertaken outside 3GPP’s technical standards area.

15. Develop Detail Assessment & Site Plan
Remote Monitoring is present everywhere and people have become
comfortable using it for many applications.
The advantages of wireless system are numerous, and challenges
associated with RMT within plants need to be addressed.
Challenges with existing systems (i.e. Lost communication) can be
minimized/avoided.
Development of site wireless assessment plan is essential for various
wireless devices
16. What are the Challenges
Typical Field Issues
• Data Loss
• Interference
• Loss Connections
Causes
• Throughput
• Number of devices
• Environmental Characteristics
• Bandwidth
• Data Rate
17. Bandwidth, Data Rate, and Throughput
• “Bandwidth” typically means one of two things:
• 1. The actual width of a frequency band measured in Hz (Hertz) where
the effective bandwidth is the frequency band that is actually carrying
data. or
• 2. The maximum data rate available (bits per second) in a
communication link.
Bandwidth
• The “data rate” of a particular wireless standard is the
maximum data transfer speed (bit per second) the
communication link can achieve, such as 54 Mbps for
802.11g. (specified transfer rate for raw data.)
Data Rate
• The actual user data rate is called the “throughput” of
the wireless link. Typically, we can expect the throughput
to be about half of the specified data rate (i.e., throughput
= 25 Mbps when data rate = 54 Mbps).
Throughput
18. Packet Loss Descriptions
“Loss” is defined as packets that did not arrive and were dropped somewhere along the
network path.
Packet loss can occur anywhere along the network path for a variety of reasons. Common
reasons include:
„„Layer-1 errors on the physical interfaces and cables along the path, such as a
malfunctioning cable and optical interface.
„„Mis-configured network interfaces along the path, such as Ethernet speed/duplex
mismatches between devices.
„„Bursts of packets exceeding the buffer (queue) limit or configurations on network
interfaces along the path, such as Ethernet switches with insufficient queue depth or
oversubscribed backplane architectures, or WAN router interfaces.
„„A poor wireless network connection due to either distance to the access point or general
network congestion.
19. Signal Throughput
Spec Max. bit rate (Mbps)
Approx. application
throughput (Mbps)
802.11a 54 26
802.11b 11 6
802.11g 54 26
802.11n (2x2) 300 80 - 100
Understanding Throughput Requirements
• Knowing the data rate that a devices will send and
receive at is critical for planning the network.
• Result Packet Data Loss
20. Channel Allocation
When using > one access point or other access
points in the area, identify the channels that will
be utilized on each adjacent access point
Avoid using the same channel as an adjacent
access point
For 2.4 GHz range - three channels (1,6 &11)
do not overlap. This will minimize a kind of
interference known as co-channel interference
21. Communication Systems –
Interconnections During Event
• As an industry, we are currently in the midst of a transformation
• We must determine how we can utilize RMT within plant site
boundaries AND off-site, in order to provide key information on:
• Radiological Parameters
• Environmental Conditions
• Personnel Health.
22. Key Planning Concepts
RMT Assessment
The overall RMT Assessment provides guidance and strengthens the plant’s approach to
ensure key information (video/audio/data) are received to be analyzed
Integrated Small Cell
The Integrated Small Cell becomes an important component of the spectrum management
plan that combines dynamic spectrum access across spectra as diverse as data, video and
audio
Emerging Techniques
Using emerging techniques such as Distributed Mobility Management (DMM), these will
provide efficient and high rate mobility solutions over localized regions, such as emergency
planning zones around nuclear facilities
23. A Future with RMT…
The vision is for integrated solutions that addresses the issue at both the network and
the customer user and management overview.
It starts with the key user devices, utilizing a smart connection manager that will fully
automate spectrum access to the point where the users will no longer have to think
about what cellular operator, what Wi-Fi SSID, what Bluetooth connection is needed
Users will simply start their apps- health monitoring. The smart connection manager will
take this information, examine the available connectivity options together with access
policies provided by the operator, and allocate the “right bandwidth” for the right
application.
24. Key Points
Successful Site Plan
Must understand System limitations and minimize communications
issues upfront
Design system for use vs ad-hoc
Expansion of monitoring capabilities of individuals
Integration of communications for onsite and offsite into one system

Editor's Notes
Newer Wi-Fi technology is beginning to spread throughout many US nuclear plants.
The expanded use of cameras and data is growing each year.
The industry’s overall RMT experience has been very favorable in terms of decreased exposure and increased worker monitoring capability with a reduced workforce.
One site reported issues with Remote system interfering with electronic dosimeters
The former is the technically correct definition of bandwidth. For example, the 802.11b/g standards operate
between 2.4 GHz and 2.4835 GHz, giving a total effective bandwidth of 83.5 MHz with a channel bandwidth of
22 MHz
In a Wi-Fi system, the actual throughput that is available to your application is generally about 50 to 60 percent of the overall bandwidth of the Wi-Fi technology selected. This is due to control and management overhead in Wi-Fi systems.
The farther a client radio is from the access point the weaker the signal will be, and as the signal gets weaker, it gets closer and closer to the noise floor. The difference between the signal and the noise floor is the signal to noise ratio. A high signal to noise ratio means that a higher performing modulation and coding scheme can be used by the radios. As the signal to noise ratio degrades, the radios must utilize a lower performing modulation and coding scheme to deal with the interference on the channel. This is called dynamic rate switching. This means that the farther the client is from the access point the lower throughput it can achieve. If your application throughput needs are high, then you must design your wireless network with more access points in closer proximity to the client radio’s location, since doing so will ensure that the radio will be able to sustain higher data rates
The Internet Engineering Task Force (IETF) develops and promotes internet standards, and dealing in particular with standards of the (TCP/IP) etc.
