Introduction (3/5)

To develop a monitorization platform based on:

• Sensor connected to GPRS network

• Data base + web in order to storage and manage data

• Data base + web in order to storage and manage data


Introduction (4/5)

The web platform:

• Users Security&Manegement

• Data storage

• Graphical representation and data analysis

• Alerts issues

• Geography representation (NO INCLUDED YET)


Introduction (5/5)

The web design team:

• NO EXPERIENCE

• Then:

Simplify the web design…

APM Systems: Main components

• Data Base.

• Agent.

• Visualization Panel and/or Dashboard.

• Alert Manager.

ELK

Elasticsearch (Database)

Logstash (Data Processor)

Kibana (Visual & Dashboard)

InfluxDB


Data Base: Requirements

• Receive, storage y consult large volumes of data.

• Efficient real-time performance.

Time Series Data Bases (TSDB): optimized for storing and

service time series through associated pairs of time(s) and

value(s) in order to follow trend processing.


InfluxDB

• Time Series Database (TSDB).

• Top one in TSDB ranking. Reference site: db-engines.com.

• High performance in order to receive large volumes of data.

• Efficient data compression.

• Configurable policies for data reduction and retention.


Line protocol

<measure>[,<tag-key>=<tag-value>...] <field-key>=<field-

value>[,<field2-key>=<field2-valor>...] [timestamp]

• <measure> string to identify the measurement.

• Similar to SQL-table structure.

• Indexed tags and no-indexed fields.

• Time stamp according to Unix nanosecond format.


Line protocol

Agent: Telegraf

• Developed by InfluxData: High compatibility and integration with InfluxDB.

• Simple and easy to configure.

• Support for many input sources.

• Light installation, plugins extinction functionalities.


Visualization panel, dashboard and alerts management: Grafana

• Easy use and integration with different systems.

• Include an alert management.

• Many complements in order to incorporate functionalities.

Installation

• Virtual machine. Ubuntu 18.10.

• Installed and configurated Telegraf, InfluxDB andGrafana.


Result Validation

Virtual machine. Ubuntu 18.10.Data

Genearator

Application:

• It simulated 10 sensors and each one receives 5 TV channels

• Values (Level, SNR and BER) are generated randomly as a

fixed value with a 5% standard deviation


Signal level


Signal level and SNR: sensor 101
