[influxdb] Re: InfluxDB Raspberry Pi installation?

2016-10-25 Thread EBRAddict 
For anyone coming across this thread, I found the apt-get install method 
stopped working when I tried on a fresh Raspbian install, it couldn't find 
the library. I'm a Linux newbie so perhaps I'm missing something obvious. I 
did get this to work:

--Update your Pi, this may take a while...

sudo apt-get update
sudo apt-get upgrade


-- get the Debian package from here. Note the file name and subdirectory 
structure may change so you might have to search for it.
wget https:
//repos.influxdata.com/debian/pool/stable/i/influxdb/influxdb_1.0.2-1_armhf.deb


-- install the Debian package
sudo dpkg -i influxdb_1.0.2-1_armhf.deb


-- start the service
sudo service influxd start


-- run the CLI
influx

[influxdb] Re: How to send sensor data to InfluxDB from Arduino Uno

2016-10-16 Thread EBRAddict 
Something similar, but using the HTTP POST using the Arduino EthernetClient 
if you're unable to modify the InfluxDB host config.

To use the code below: 1) Change the MAC address, 2) change the IP address 
to your InfluxDB IP address, 3) change the line in the POST construction to 
your InfluxDB and Port "client.println("Host:  192.168.1.136:8086");"

It starts breaking down when the loop delay is around 300ms. The POST is 
coming from a microcontroller and going to a Raspberry Pi 3.

#include 
#include 


// Enter a MAC address for your controller below.
// Newer Ethernet shields have a MAC address printed on a sticker on the 
shield
byte mac[] = { 0x00, 0x1A, 0xB6, 0x02, 0xF1, 0x16 };
IPAddress server(192, 168, 1, 136); // BBB

// Initialize the Ethernet client library
// with the IP address and port of the server 
// that you want to connect to (port 80 is default for HTTP):
EthernetClient client;


//data for HTTP Post;
String POSTData = "";

//data for HTTP response
char Response[255];

void setup()
{

//start Serial
Serial.begin(115200);

//initialize ethernet
if (Ethernet.begin(mac) == 0)
Serial.println("Failed to configure Ethernet");

// give the Ethernet peripheral a second to initialize:
delay(1000);

// let the monitor know it's starting
Serial.println("Starting");

  
}

void loop()
{

// connect to the influxdb port
if (!client.connect(server, 8086)) 
Serial.println("Did not connect");

// set some test data
String POSTData = "uCont value=" + String(millis());


// Make a HTTP request:
client.println("POST /write?db=mydb HTTP/1.1");
client.println("Host:  192.168.1.136:8086");
client.println("User-Agent: Arduino/1.6");
client.println("Connection: close");
client.println("Content-Type: application/x-www-form-urlencoded;");
client.print("Content-Length: ");
client.println(POSTData.length());
client.println();
client.println(POSTData);

delay(30);

if (client.available())
{
client.readBytes(Response, client.available());
Serial.println(Response);
}


delay(1000);

// let the monitor know something is going on in case nothing is returned.
Serial.println("loop...");

}

[influxdb] InfluxDB Raspberry Pi installation?

2016-10-13 Thread EBRAddict 
Hi,

I'd like to try InfluxDB on a Raspberry Pi 3 for a mobile sensor project. 
Currently it's logging ~50 data points every 200ms to a USB flash drive 
text file but I want to ramp that up to 200 every 10ms, or however fast I 
can push data from the microcontrollers to the Pi.

I downloaded and uncompressed the ARM binaries using the instructions on 
the InfluxDB download page:

wget 
https://dl.influxdata.com/influxdb/releases/influxdb-1.0.2_linux_armhf.tar.gz
tar xvfz influxdb-1.0.2_linux_armhf.tar.gz


What are the next steps? I'm not a Linux guy but I can follow directions if 
someone could point me to them. I'd like to configure the service(s) to run 
at startup automatically and be accessible for querying by any logged in 
user (it's a closed system).

Thanks.
