This document discusses InfluxDB, an open-source time series database. It stores time stamped numeric data in structures called time series. The document provides an overview of time series data, describes how to install and use InfluxDB, and discusses features like its HTTP API, client libraries, Grafana integration for visualization, and benchmark results showing it has better performance for time series data than other databases.

1. TSDB
INFLUXDB A TIME SERIES DATABASE
Created by Gianluca Arbezzano / @GianArb

2. TSDB
TIME SERIES DATABASE
It is a software system that is optimized for handling time series
data, arrays of numbers indexed by time (a datetime or a
datetime range)

3. LEARN STARTUP

Innovation to Create Radically Successful Businesses

4. TIME SERIES DATA
A time series is a sequence of data points, measured typically at
successive points in time spaced at uniform time intervals

5. OTHER POSSIBILITY
Google Analytics
Amazon CloudWatch
...

6. INFLUXDB
An open-source distributed time series database with no
external dependencies

7. it is written in Golang
wget http://s3.amazonaws.com/influxdb/influxdb_latest_amd64.deb
sudo dpkg -i influxdb_latest_amd64.deb
Docs

8. WHY?
Real time
Easy
Scalable
Http api & Client(php, python, ruby...)
Single source

9. OPEN SOURCE
Github

10. GRAFANA
An open source, feature rich metrics dashboard and graph editor
for Graphite, InfluxDB & OpenTSDB.

11. GETTING STARTED
curl -X POST
-d '[
{
"name" : "hd_used",
"columns" : ["value", "host", "mount"],
"points" : [
[23.2, "serverA", "/mnt"]
]
}
]'
'http://localhost:8086/db/mydb/series?u=root&p=root'

12. MORE POINTS FOR INSERT
[
{
"name": "log_lines",
"columns": ["time", "sequence_number", "line"],
"points": [
[1400425947368, 1, "this line is first"],
[1400425947368, 2, "and this is second"]
]
}
]

13. IMPLEMENT UDP
PROTOCOL
[input_plugins.udp]
enabled = true
port = 4444
database = "search"
InfluxDB is down? Your APP works!

14. BENCHMARK UDP VS TCP
CorleyBenchmarksInfluxDBAdapterEvent
Method Name Iterations Average Time Ops/second
------------------------ ------------ -------------- -------------
sendDataUsingHttpAdapter: [1,000 ] [0.0026700308323] [374.52751]
sendDataUsingUdpAdapter : [1,000 ] [0.0000436344147] [22,917.69026]

15. QUERY
curl 'http://localhost:8086?u=root&p=root&q=select * from log_lines limit 1'
[
{
"name": "log_lines",
"columns": ["time", "sequence_number", "line"],
"points": [
[1400425947368, 287780001, "here's some useful log info"]
]
}
]

16. ADMIN PANEL:8083

17. FEATURES
Create database
Manage users
Query and Graphs

18. GRAFANA
Is an Javascript OpenSource Dashboard
Drag and drop panels
Click and select region to zoom
Bars, Lines, Points
Mix lines, bars and points
InfluxDB query editor
Annotation lines

19. ANNOTATIONS?!
You can mark deploy and monitoring differences between two
versions

20. CORLEY/INFLUXDB-PHP-SDK
Another influxdb SDK written in PHP

21. INSTALL
php composer.phar require corley/influxdb-sdk:dev-master

22. ADAPTER SYSTEM
Very flexible
UDP Adapter
Guzzle Adapter
Your implementation..

23. CREATE CLIENT
$options = new InfluxDBOptions();
$adapter = new InfluxDBAdapterUdpAdapter($options);
$client = new InfluxDBClient();
$client->setAdapter($adapter);

24. FACTORY PATTERN
$options = [
"adapter" => [
"name" => "InfluxDBAdapterGuzzleAdapter",
"options" => [
// guzzle options
],
],
"options" => [
"host" => "my.influx.domain.tld",
],
"filters" => [
"query" => [
"name" => "InfluxDBFilterColumnsPointsFilter"
],
],
];
$client = InfluxDBClientFactory::create($options);

25. MARK YOUR EVENT
$client->mark("error.404", ["page" => "/a-missing-page"]);
$client->mark("app.search", $points, "s");

26. QUERY
$influx->query("select * from mine");
$influx->query("select * from mine", "s");
$client->setFilter(new ColumnsPointsFilter());
$data = $client->query("select * from hd_used");

28. RICHARD FEYNMAN - THE KEY TO SCIENCE
1. Guess
2. Compute Consequences
3. Compare with experiment/experience
