Eventhough utility like LatencyMon is useful to test Winodws latency, PowerShell provides a cmndlets “Get-Counter” (example copied below). This cmndlets can run for an interval of time or continuously.
E.g for short interval run:
Get-Counter -Counter “\Processor(_Total)\% Processor Time” -SampleInterval 5 -MaxSamples 2

Sample interval 5 means every 5 sec counter checks it and Maxsamples 2 means 2 results are generated.
E.g. for continuous run:
Get-Counter -Counter “\Processor(_Total)\% Processor Time” -Continuous

Latency issues generally occurs as a side effects of patch updates in windows. It may occur as audio/video streaming performance issues.
Latency issues can be tested using LatencyMon or Thesycon 
Note : Thesycon is more effective on lower versions on windows like 7 or lower.

BaldeLogic is a server automation suite. 
An admin needs to manage sever configuration, patching,  compliance, change control, change management, provisioning etc.
BaldeLogic does this automation when several server needs this activities to be done. 
In order to Bladelogic infrastructure has BSA centralized interface using that admin sets configuration,  deploy, etc for any number of servers. 
All servers needs an agent to be installed. BSA uses port 4750 to call all the agents and achieve this requirement.

Ansible is an IT automation tool to fulfill DevOps requirements. Ansible is written in Ruby, python, and powershell.

Ansible is used for cloud provisioning, application deployments, server patching , rebooting, configuration management, and many more IT tasks fulfillment.

Ansible Scripts are written in ansible playbook(s). I will include few sample playbooks and explain the its own declarative language below in this article.

What’s make Ansible so unique and top winner?

The main feature of Ansible is that it does not need Agents or any other special security infrastructure unlike other IT automation tools in the market.
Ansible just needs its automation jobs written in YAML file called as Ansible playbooks. 

What is Ansible Role directory structure ?

Role directory structure contains tasks, handlers, vars, files, templates etc. Roles helps to automatically load these. Ansible playbook is a mapping between hosts and Roles. E.g. are site.yml, webserbers.yml etc. While roles are set of tasks and variables.
Typical ansible directory layout contains inventory files to represent production and other staging environments.There will be master playbook yml files, webserver, dbserver yml files, other libraries representing custom modules like utility, plugins yml files, group and host representatives yml files, then roles as discussed above contains set of yml files and finally if needed monitoring yml files can also be added to a playbook.
