When Do Most Companies Start Monitoring?

When a Client calls about a problem. Staging / Pre-Production Going to Production. When the management is asking for reports about SLA.

Why do you WANT monitoring?

Know the state of the servers.Know the state of the service/product you provide.Be able to anticipate issues before clients are

aware of them (proactive).

Why Do You NEED Monitoring?

Know the state of the server.Know the state of the service/product you provide.Be able to anticipate issues before clients are aware of them (proactive).Gather behavioural data about the system.Learn about bottlenecks in the system and plan to avoid them.Tracking the changes that happen on the system.

Monitoring starts when your code is first tested!!

What do we want to monitor ?

Laptops ? Servers? VoIP Phones?Printers? Switches? PBX ?Storage? FireWalls?Routers? AP's ?Before we select the tool, we need to define the

scope of what to include.

And more to the point – What NOT !!

How do you go about setting up monitoring ?

Market research to select which tool to use.

And many more Tools...

Use an external service. Hire external consultants. Build a full NOC.

Support ?

Community

ProfessionalDedicated support personnel.Provides SLA.Known entity to communicate with.Not depended on the “kindness of others”

Use the tool you know For Against

Fast implementation “waste time for DEV system”

Easy to set up “will not be the real product”

Easy to hand over You don't care – it is for

data gathering

It is easy to start

Monitoring Hooks

Who knows what to look for ?• Most often- the Person that wrote the code

How involved are they in the process ?• Mostly,non at all

Conclusion

* Start monitoring early. * Involve Dev in the monitoring process. * Make it part of CI (same as Unit testing). * Gather as much data as possible, as early as

possible. * Expose the data to the management and

architects. * Always highlight any abnormal occurrence.
