Grafana with InfluxDB for Domoticz

[Trigun]

Ok; sounds great! I am a php noob though but I'll definitely check it out! For now I only need the function to send data to the influx db. So I can use it in grafana.

The InfluxDB data push on Domoticz is broken, dates do not load correctly in InfluxDB, putting them out of range and resulting in empty charts in Grafana even though it has a connection with the database.

Don't waste your time trying to get this to work until the data push is fixed.

Hi, I checken the outcome in domoticz and grafana with influx seem to work fine. I believe it's a matter of configuration. How do you know it's broken?

I am running Domoticz version 3.6708 2017/02/14. The Influx data push code was significantly changed in this version and the timestamps data is not correctly loaded. There is no adjustable configuration for the timestamp in this version.

All my sensor data are loading into InfluxDB with no problem using the Influx data push. Unfortunately, without usable timestamps

I also spent many hours trying to configure HTTP push. Unfortunately, the problem is exactly opposite...the timestamps work perfectly, but I have been unable to get the data elements required to work.

In this thread I detailed my issues. https://www.domoticz.com/forum/viewtopi ... 28&t=16108

I am not surprised if earlier versions of InfluxDB push and HTTP push are working differently.

Has ANYONE using Domoticz 3.6.08 + been successful using Influx Data Push? I would be happy to be proven wrong, but I've spent nearly two days trying to resolve this problem.

Please include your Domoticz version number, at the top left of your screen below the Domoticz logo, if you reply with any information.

Hi grubstake, allthough i am sending my data to the influx db via php now, I did use the http push within domoticz 3.587 for quite a while without any issues. Perhaps it's a version issue? I did see that in the featurelist for the new version the http push has been re-developed. I suggest try to run the last stable version 3.587 see how that works out.

Hi, I have InfluxDB and Grafana working on a Raspberry Pi 3. Thought I'd dump the complete instructions as it may save someone some time.

Domoticz: 3.5877
Influxdb: 1.2.4
Grafana: 4.1.2

Install InfluxDB

Code: Select all

sudo apt-get update
sudo apt-get upgrade
wget https://dl.influxdata.com/influxdb/releases/influxdb_1.2.4_armhf.deb
sudo dpkg -i influxdb_1.2.4_armhf.deb
sudo nano /etc/influxdb/influxdb.conf

Uncomment and set these options:

Code: Select all

[admin]
  # Determines whether the admin service is enabled.
enabled = true
  # The default bind address used by the admin service.
bind-address = ":8083"
[http]
  # Determines whether HTTP endpoint is enabled.
 enabled = true
  # The bind address used by the HTTP service.
bind-address = ":8086"

Start InfluxDB with:

Code: Select all

sudo service influxdb start

Go to: http://[IP]:8083/
CREATE DATABASE "domoticz"
Setup the user (domoticz/domoticz) in InfluxDB Connection Settings:

In Domoticz go to: Setup => Settings => Data Push => HTTP Link
Use the following URL:

Code: Select all

http:// [IP]:8086/write?db=domoticz&u=domoticz&p=domoticz&precision=ms

Setup the sensors like in this screenshot (device_+"Target Variable" will be the table name in InfluxDB:

Verify that there's data in the relevant InfluxDB table, e.g. SELECT * FROM deviceX

Grafana install

Code: Select all

wget https://github.com/fg2it/grafana-on-raspberry/releases/download/v4.1.2/grafana_4.1.2-1487023783_armhf.deb
sudo apt-get install -y adduser libfontconfig
sudo dpkg -i grafana_4.1.2-1487023783_armhf.deb

Add this to /etc/rc.local

Code: Select all

sudo service grafana-server start

Code: Select all

sudo reboot

Access at:
http:// [IP]:3000
admin/admin
Add datasource

Hello

I can't get influxdb working, could someone give me a hand, see this thread: viewtopic.php?f=6&t=18619
Thank you

This is very nice Wiki material

Hi, I have InfluxDB and Grafana working on a Raspberry Pi 3. Thought I'd dump the complete instructions as it may save someone some time...

I followed this tutorial and it worked great!
I find InfluxDB to be a pain though if you need to remove a data point (like, you can't actually delete it - you have to add in a new value with the same timestamp). Grafana is very interesting - just wish there was better SQL Server integration as that is what I have most of my data in (I am a data scientists by trade).

[gizmocuz]

InfluxDB is a great database, and once correctly setup, it's a no-brainer.
True... a native grafana->domoticz implementation would be great!
These days it is very easy to install everything via a 'docker' , for instance with portainer.io on a modern odroid uc4

[kurniawan77]

Is it possible to "PUT" my data from the past three years into influxdb?

[dlefol]

Hello,

Did you find a way to push your past data into Influx ? I'm starting to look at Influx and would like to push my historic data too.

Cheers

[gizmocuz]

you could make a bash script for this... it won't be easy

[Derik]

Dear all.
Do i need to install Grafan on the same hardware where is domoticz is on running?
Or can i run on a other [ slave ] domoticz device..?

[Trigun]

you can run it on any device as long as you point the data towards the device on which the database is running and just point Grafana to the dB server

Those two can be on the same server by the way

It doesn't have to be domoticz, at all. My goal this week is to install it next to Max2play

[thorian]

Couple of notes:
- the 'old HTTP Send' still works very well with newest Domoticz
- the ESPEasy software has now Advanced Generic HTTP which allows direct InfluxDB update, works along the Domoticz or/and MQTT update

In stable version de Data push influxdb is working.
Should data push influxdb in beta (3.8755) work?
I don't see anything in log when Debug to logfile is on.

Edit: suddenly it is working. Forget this please.

[glsf91]

Is InflluxDB not working with Xiaomi temperature sensor (through gateway)?

I don't see anything in InfluxDB or Influxlink messages in the logfile.

Other temperature sensor (by RF) are working.

Edit: Temperature sensor is not working with influxdb. But the combined Tem+Humidity sensor is working with influxdb.

I installed a couple of days ago Influxdb (latest version so also needed to install Chronograf) and started using the native integration with 5+ temp sensors. That is the only bigger change in my setup (RPi3, latest Domoticz beta) for a few weeks and I've now witnessed unresponsive web gui about every six hours (Monit restarts Domoticz if it cannot fetch the json url for status but from the logs it seems that Domoticz keeps running normally and no errors in the log) and CPU usage has gone from avg 2% to 5% while RAM usage has increased from 10-15% range to 20-25% (as recorded by the internal hardware sensors in Domoticz).

Before these changes Domoticz would have an uptime of 1-5 days at least (not sure why it has not been longer than that for a few months now, maybe related to the memory leakage) so change is quite clear. Has anyone else witnessed something like this and any pointer of how to make it more stable?

[dlefol]

My repy is a bit late so hopefully you found a solution already but on my system (similar setup with RPi3, influx and Monit), I started having issues with Monit restarting domoticz regularly and unresponsive web ui too. It always seemed to coincide with the automatic backup that domoticz was doing of the database (every hours). It got worst after installing influx and I guess it's related to influx producing a lot of read and/or write on the SD card at the same time and thus making the backup of the DB longer (only a guess I can be completely wrong).
I recently bought a PiDrive (hard drive for RPi) to replace my SD card and it improved quite a lot the situation (1 or 2 monit reboot in the past couple of month at most instead of once a week maybe before). I think this is due to the hard drive having faster access time than the SD card I was using before.

I use Pass2PHP ;-0

Code: Select all

<?php

        $input = ($s['Electra']);
        $meter = explode(";",$input);
        
        influxdb("Electra_Usage",$meter[4]);
        influxdb("Electra_Return",$meter[5]);

And dump the data straight into influxdb.

If you would use Pass2Php the function could looks like:

Code: Select all

function influxdb($device,$value)
{
// FAMOUS STRING REPLACEMENT UTILITY
    if (strpos($device, " ") !== false) { $device=str_replace(" ","_",$device); }
// ENDOF FAMOUS STRING REPLACEMENT UTILITY
   $postdata = ("device_$device value=$value ".system('date +%s%N'));
//   lg('InluxDB Data: '.$postdata);

    $opts = array('http' =>
        array(
            'method'  => 'POST',
            'header'  => 'Content-Type:application/octet-stream',
            'content' => $postdata
        )
    );

    $context  = stream_context_create($opts);
    $result = file_get_contents('http://192.*.*.*:8086/write?db=domoticz', false, $context);
}

hi mate,
long time no see :p
just wondering if you have an 'updated' version of your influx program in php?
I want to use it also, i was writing something myself, but why writing something on my own, when there is already something existing :p
