Large Scale Deployment Stress
2015 3
Goals: Rapid Deployment of Services
Cut Deployment Time by 50%Through accurate analysis and the use of scripts reduce the time needed to create an efficient design.
Increase Efficient Management by 75%Dramatically change the way service checks, templates and hosts are implemented and managed.

Strategy Context
2015 5
Strategy: Analysis
Hardware / VirtualEvaluate the type of server you will be monitoring to implement SNMP for hardware and monitor the hosts for the virtual
environments.
Network Topology and FirewallsList the network infrastructure that will be monitored, the firewall
limitations and the data centers.
Host TypesThis analysis will also require the version of the OS as well as the
environment it will be running in like production, developement,
etc.
SettingsAnalyze each of the triggers for each service check required and
who will be included in the notification/escalation process.
2015 6
Strategy: Design
Network Requirements* firewalls* data centers
Host Requirements* What needs to be checked?
Service Check Requirements* triggers
* timing
Notification/Escalation Requirements* Who gets notfied and when.
2015 7
Strategy: Evaluation
Build a Test Environment* Simulate the real thing!
Build One Host for Each Type* Hammer them...verify everything.
Build Notification/Escalation* Do the work, implement as you go

Strategy: Efficient Management
Create Leverage * Control Services From One Template* Plan for Exceptions
5 Piece Model* host
* host template (attached to host)* hostgroup (attached to host)
* service template (attach to hostgroup)
* services (attach to service template)

Principles for Service Check Group Deployment
Group Prepared ChecksCreate groups of checks that allow for rapid deployment of services needed. (CPU checks, Memory checks, etc.)
Efficient Management of Group ChecksUsing object inheritance create service templates and services.
Script DeploymentBuild scripts that will enable you to input data to create pre-created
templates and services.

Script Functions
Deploy Selection of Group
Deploy Token and IP AddressThis process build useful service checks so you do not need to make modifications.

NCPA:Windows Perf Counter Definitions
Write Definitions Create definitions for each counter so users have some idea about what the
counter does.
Group DefinitionsCreate groups for definitions so the user can review relevant
information and options.
Access the Definitions from the Script
2015 22
Windows Perf Counter Definitions: Examples
Processor:% Processor TimeThis counter measures how much time the processor spends in productive time. The counter simply subtracts the percentage from
100%. So in the example “1” indicates it is only doing productive activities for 1% of the time. Note this check is for core “0”, for
additional cores change that number. If you wanted to check all
core use “*”.
TCPv4: Connection Failures This is the raw number of TCP connections that have failed since
the server was started. This will typically incur a loss of data so you should pay attention to this counter.

Group DefinitionsCreate groups for definitions so the user can review relevant information and options.

Browser API Access
API Checks with BrowserThe purpose of the script is to convert the desired group into usable checks to be
dropped into a browser.
Convert Links to ASCIIIn order for the links to work, they must be converted into ASCII.Your browser will encode input, according to the character-set used in your page. The default
character-set in HTML5 is UTF-8.
