Why Do We Need Cloud Based Monitoring ?
Provide a catalogue of
standard reports that you
can use to analyse trends
and monitor system
performance
To reduce unnecessary
operating costs by sending
notifications in case of
unreasonable prising
issues.
Detect problems early to
prevent disasters. Also
prevents and reduce
downtime and business
losses
Monitor the end users
experience and create
reports which help to
make improvements.

Amazon CloudWatch Concepts
A metric represents a time-ordered set of data points
that are published to CloudWatch. Think of a metric as
a variable to monitor, and the data points represent
the values of that variable over time.

Metrics
Dimensions
A dimension is a name/value pair that uniquely
identifies a metric. They can be considered as
categories of characteristics that describe a
metric. We can assign up to 10 dimensions to a
metric

25. AWS Architect Certification Training https://www.edureka.co/cloudcomputing
Amazon CloudWatch Concepts
Statistics
Statistics are metric data aggregations over
specified periods of time. Aggregations are
made using the namespace, metric name,
dimensions within the time period you specify.

Statistics
Alarm
Statistics are metric data aggregations over
specified periods of time. Aggregations are
made using the namespace, metric name,
dimensions within the time period you specify.
An alarm can be used to automatically initiate
actions on your behalf. It watches a single
metric over a specified time period, and
performs one or more specified actions.

Amazon CloudWatch Events

30. AWS Architect Certification Training https://www.edureka.co/cloudcomputing
Introduction To Amazon CloudWatch Events
Amazon CloudWatch Events is a part of Amazon CloudWatch which delivers ‘a near real-time stream of
system events’ that allows you to ‘monitor and respond to the changes in your AWS resources’ by means of
rules that route events to one or more targets.

31. AWS Architect Certification Training https://www.edureka.co/cloudcomputing

your AWS environment. AWS
resources generate events
