Looking for the Perfect Dashboard: InfluxDB, Telegraf, and Grafana – Part XXXVI (Monitoring Goldshell Miners – JSONv2)

- Written in: opensource

Greetings friends, it’s been a while since I’ve added to the In Search of the Perfect Dashboard series, but it’s time to continue. Today I bring you a very interesting post, that I was really looking forward to adding to the series, it’s about how to collect Goldshell Miners statistics, using the new JSON Parser v2.

Once we finish all the steps, you should have a result similar to the following:

As you may know, if you use Goldshell, it looks like the default interface of the solution.

What is Goldshell Miner?

Goldshell is a well-known brand that produces mining machines better known as ASIC. The only purpose of these devices is to mine cryptocurrency, they do not serve for anything else, in fact, they only have an Ethernet port and another one for electricity.

I am using, in particular, the Goldshell Mini-DOGE which mines, using scrypt, LTC, and DOGE, it does not have a very high hash rate, only 185 MH/s or so, which is more than enough really.

How much money does this machine generate? I leave you my numbers, which may be more or less depending on the value of the coin we mine, in this case, LTC and DOGE, when I write this it is somewhat low, LTC at 173.15, and DOGE at 0.18, this is what it has generated in the month of October 2021:

65,66 Euros in total has generated the machine, depending on your electricity rates, and if DOGE and LTC go up some more, we could pay the cost, 700 Euros, of the machine in a year or a little less. This is not financial advice, do your own research, buy it or not. This entry is, as usual, to see how to monitor this equipment.

Configuring Telegraf to parse the new .json and send it to InfluxDB

This time I am going to use the always versatile inputs.http, to parse directly from the .json, the configuration could not be easier, I have created a new file under /etc/telegraf/telegraf.d/goldlshell.conf with this inside, just change the URL to your GoldShell:

[[inputs.http]]
    urls = ["http://YOURGOLDSHELLIP/mcb/cgminer?cgminercmd=devs"]
    data_format = "json_v2"
        [[inputs.http.json_v2]]
            measurement_name = "goldshell_stats"
        [[inputs.http.json_v2.object]]
            path = "data"

[[inputs.http]]
    urls = ["http://YOURGOLDSHELLIP/mcb/status"]
    data_format = "json_v2"
        [[inputs.http.json_v2]]
            measurement_name = "goldshell_stats"
            
            [[inputs.http.json_v2.field]]
                path = "hardware"

            [[inputs.http.json_v2.field]]
                path = "model"

            [[inputs.http.json_v2.field]]
                path = "firmware"

To test that everything is working properly we launch the following:

telegraf --config /etc/telegraf/telegraf.d/goldhsell.conf --test

The command should give us something similar to the following if everything works well:

> goldshell_stats,host=tig-monitor,url=http://192.168.1.245/mcb/status firmware="2.1.2",hardware="10.10.SA",model="Goldshell-MiniDOGE" 1637944046000000000
> goldshell_stats,host=tig-monitor,url=http://192.168.1.245/mcb/cgminer?cgminercmd\=devs accepted=7811,adjustpower=0,av_hashrate=187.002,fanspeed="1560 rpm / 1500 rpm",hashrate=172.81200000000004,hwerr_ration=0.001166,hwerrors=748,id=0,minerstatus=0,nonces=644008,powerplan=0,rejected=11,temp="77.3 °C",time=3078,valid=0 1637944046000000000

We will now have to restart the telegraph service:

systemctl restart telegraf

If we go to our Grafana – Explorer, we can see that we have data!

Grafana Dashboard to see everything in a centralized way.

Now that we have all this information, we probably want to show it in a more elegant way.

By simply importing the following Dashboard using the Grafana URL, you will have something similar to this:

At the end of it all, if everything went well, you will be able to see your cool Goldshell Dashboard and know your hashrate, hw errors, etc.

I hope you like it, and I would like to leave you the complete series here, so you can start playing with the plugins that I have been telling you about all these years:
