Hi All,
I want to learn how to make a simple TIG stack (or similar) to monitor some data. Perhaps starting with my computers metric (cpu, ram usage etc) but eventually from a sensor.
I now have a RPi ready to go running Rasbian and the first step is installing Telegraf to collect some data.
I’m trying to follow this:
> **[Get started with Telegraf | Telegraf 1.21 Documentation](https://docs.influxdata.com/telegraf/v1.10/introduction/getting-started/)**
>
> Configure and start the Telegraf service.
But I’ve gotten stuck at the first hurdle - Install Telegraf.
Just a side note, I’m completely new to the world of Influx, and only basic proficiency on the Raspberry Pi.
I’ve managed to download Telegraf Binary and unzip.
I navigate to
```
cd /home/pi/telegraf/usr/bin
```
then
```
./telegraf
```
It says starting telegraf. Then Error running agent no config file specified…
Any thoughts appreciated 🙂

You will need to [create a config file](https://docs.influxdata.com/telegraf/v1.10/introduction/getting-started/#creating-and-editing-the-configuration-file), then start Telegraf with it: `./telegraf --config telegraf.conf`
I recommend trying the `.deb` file since it is setup to run Telegraf as a service using a config in `/etc/telegraf/telegraf.conf`, this is a bit nicer once you get past the early testing stage.

Ok thanks for the reply, seem to have something happening now.
I did…
./telegraf -sample-config -input-filter cpu:mem -output-filter influxdb \> telegraf.conf
Instead of
telegraf -sample-config -input-filter cpu:mem -output-filter influxdb \> telegraf.conf
as the tutorial suggested, to monitor cpu and mem usage. Probably obvious to others but I’m quiet new.
I then started telegraf as you suggested.
However, it now says " Error writing output… could not write to any address…connection refused"
Is this to do with permissions on the RPi perhaps?

Hi ,
that is because Telegraf expects an influx database up and running ,
because of the outputs part in the config.
Do you have Influxdb installed ?
best regards

Hi,
Sorry for the really late reply on this - I’ve been on other projects of late.
I see, no I don’t have Influxdb installed. I’ve now downloaded Influx1.7.6 but am having trouble installing.
I’ve run…
```
wget https://dl.influxdata.com/influxdb/releases/influxdb-1.7.6_linux_armhf.tar.gz
tar xvfz influxdb-1.7.6_linux_armhf.tar.gz
```
This has unzipped the files on my Raspberry Pi home. I can see a bin folder with lots of executables. Not sure how to install though.
As described I’m quiet new to RPi.
Any pointers most welcome 🙂
Cheers

Isn’t influx available as a Raspbian package?

What does “aptitude search influx” tell you?
If it gives an error, please confirm what Operating System you’ve installed on
the Raspberry.

Hi
```
aptitude search influx
```
returns
E: the list of sources could not be read
I am running Rasbian OS.
Does this mean I need to follow Debian from install page?..

Oh dear, that’s bad - it means you can’t install new software, update existing
software, or obtain security updates for your Raspberry.
> I am running Rasbian OS.
I wonder how you installed it…
> Does this mean I need to follow Debian from install page?..
It means you should check the contents of:
/etc/apt/sources.list
/etc/apt/sources.list.d/\*
You should also make sure you have a working Internet connection to the
Raspberry (which I guess is true because you managed the wget) and a working
DNS service (ditto).

Ok so
/etc/apt/sources.list
is a file with three lines that says to un-comment bottom line to enable apt-get source
and
/etc/apt/sources.list.d/\*
Has a similar file as described above called raspi.list and an influxdb.list file.
Internet connection is fine.
Should I un-comment the bottom lines in these files?

What _exactly_ does it say?
It’s nothing confidential - there’s no reason not to post it to a public
mailing list.
It _should_ be a working sources.list file, from wherever you installed
Raspian, but it sounds like there’s a problem.
> and /etc/apt/sources.list.d/\* has a similar file as described above called

How similar? I know this is getting off-topic for InfluxDB, but post the
contents of those files as well.
> Internet connection is fine.
Good.
> Should I un-comment the bottom lines in these files?
I don’t know until I know exactly what they say.

also there is a sources.list.d/influxdb.list file
Does this make more sense?

And the influxdb file just one line
