Different presentation mediums ( 5 of 17) Capacity Management, Telling the Story

There are a variety of different presentation methods that we can use:

Dashboards / Web portals – these typically show red, amber and green status as they are very quick to assimilate.

•         More suited for technical staff and business users

•         Different look for each area

Word Documents

•         More suited for “C” level executives

•         Upfront summary is critical

•         Historical document

PowerPoint documents

•         Used for different types of presentations

•         Good for discussion groups

Choose your style to suit your audience and to suit the type of data that you are displaying.

On Friday we'll take a look at the types of data that you’ll be displaying.

In the meantime don’t forget to our register for our webinar ‘Windows Capacity Management 101' http://www.metron-athene.com/services/webinars/index.html

Key Capacity Metrics - Top 5 Key Capacity Management Concerns for UNIX/Linux (11 of 12)

What key capacity metrics should you be monitoring for your Big Data environment? My list includes some key CPU, Memory,  File System and I/O metrics which can give you a good understanding of how well your systems are performing and whether any potential capacity issues can be identified.

•      Standard CPU metrics

o  utilization, system/user breakdown

•      Memory

o  Usage, Paging, Swapping

•      User/Process breakdown – define workloads

•      File System

o  Size

o  Number of Files

o  Number of Blocks

o  Ratios

o  User breakdown

•      I/O

o  Response time

o  Read/Writes

o  Service times

o  Utilization

By capturing the user/process breakdown on your UNIX/Linux systems, we can start to define workloads and couple that with the predicted business usage to produce both baseline and predictive analytical models. 

Some of the following key questions can then be answered:

•      What is the business usage/growth forecast for next 3, 6, 12 months?

•      Will our existing infrastructure be able to cope?

•      If not what will be required?

•      Are any storage devices likely to experience a capacity issue within the next 3,6,12 months?

•      Are any servers or storage devices experiencing any performance issues and what is the likely root cause?

This is not an exhaustive list, but it does provide information on the key capacity metrics you should be monitoring for your Big Data environment. 

In my final blog on Wednesday I'll be looking at CPU breakdown and summarizing. In the meantime sign up to our Community for access to some of our great Capacity Management resources such as white papers and on-demand webinars http://www.metron-athene.com/_resources/published-papers/login.asp
