# What is the difference between Telemetry and Metrics?

## The difference between telemetry and metrics

is that "telemetry" is the science, and associated technology, of the automatic recording and transmission of data from a remote source to a receiving station for analysis and "metrics" is of or relating to the metric system of measurement.

# metrics

### Noun

• (applied sciences) the science, and associated technology, of the automatic recording and transmission of data from a remote source to a receiving station for analysis

• Of or relating to the metric system of measurement.
• (music) Of or relating to the meter of a piece of music.
• (mathematics, physics) Of or relating to distance.

### Noun

• A measure for something; a means of deriving a quantitative measurement or approximation for otherwise qualitative phenomena (especially used in engineering).
• (mathematics) A function for the measurement of the “distance” between two points in some metric space: it is a real-valued function d(x,y) between points x and y satisfying the following properties: (1) “non-negativity”:

d
(
x
,
y
)

0

{displaystyle d(x,y)geq 0}
, (2) “identity of indiscernibles”:

d
(
x
,
y
)
=
0

iff

x
=
y

{displaystyle d(x,y)=0{mbox{ iff }}x=y}
, (2) “symmetry”:

d
(
x
,
y
)
=
d
(
y
,
x
)

{displaystyle d(x,y)=d(y,x)}
, and (3) “triangle inequality”:

d
(
x
,
y
)

d
(
x
,
z
)
+
d
(
z
,
y
)

{displaystyle d(x,y)leq d(x,z)+d(z,y)}
.

• (mathematics) A metric tensor.
• Abbreviation of metric system.

#### Synonyms

• measure
• (mathematics): distance function

#### Hyponyms

• (mathematics): Euclidean metric, Hausdorff metric, spacetime metric, uniform metric, ultrametric

#### Examples

• As for the large number of official statements that Spain is safe, I think they are merely a metric of the complacency that has characterised the European crisis from the start.
• Economics is a messy discipline: too fluid to be a science, too rigorous to be an art. Perhaps it is fitting that economists’ most-used metric, gross domestic product , is a tangle too. GDP measures the total value of output in an economic territory. Its apparent simplicity explains why it is scrutinised down to tenths of a percentage point every month.
• What metric should be used for performance evaluation?
• What are the most important metrics to track for your business?
• It’s the most important single metric that quantifies the predictive performance.
• How to measure marketing? Use these key metrics for measuring marketing effectiveness.
• There is a lack of standard metrics.
• As we shall see, these metrics are constructed from a Green function.

### Verb

• (transitive, aerospace, systems engineering) To measure or analyse statistical data concerning the quality or effectiveness of a process.

#### Examples

• We need to metric the status of software documentation.
• We need to metric the verification of requirements.
• We need to metric the system failures.
• The project manager is metricking the closure of the action items.
• Customer satisfaction was metricked by the marketing department.
