Graphs shows "no data"

[nathanael-h]

Hello, I do have the same problem, I followed your advices @jhammons - thanks- but I still have no data in Grafana. In Netdata it works. I think I have the same problem as @Quiwy .
I reinstalled both Netdata and Grafane, strating with Netdata.

I've really missed reactivity for the past months/years... But today I'm releasing a fix version of this package that should make working any initial installation, and your comments/PR helped a lot! Thanks! ❤️

The issue is that influxdb (/etc/influxdb/influxdb.conf) doesn't have opentsdb enabled for some reason. I worked around the issue by adding this to the configuration:

[[opentsdb]]
  enabled = true
  bind-address = ":4242"
  database = "opentsdb"

Then, restart influxdb and data should be flowing.

Still have 'no data' on graphana charts after modifying the file 😟

[jchammons]

Oh, one thing I had to do that I failed to mention. I installed influxdb-client, ran influx and then create database opentsdb ... I hope that helps.

Also, did you restart netdata? sudo systemctl restart netdata.service ?

[Quiwy]

Still have nothing in graphana 😟 , even if it looks like there is something in the influx database (not sure how to read it though).

SHOW MEASUREMENTS ON opentsdb

Yes I restarded netdata service too, and no change.

[jchammons]

So you just need to make sure Grafana is reading from influxdb properly. What do the settings for InfluxDB in 'Data sources' reveal? Is 'opentsdb' the database name?

[Quiwy]

HEre are the details of data sources in graphana configuration.

[jchammons]

I think you should not set the HTTP Method.

[Quiwy]

Well, the HTTP method was set by default to post, I changed nothing on this parameter, and it doesn't works with get method neither.

I had the same issue today, and was able to resolve it thanks to the comments above, mostly following the installer script line by line. I found that exporting.conf didn't exist for me in the netdata conf section. Changing the influxdb conf was a headfake, I ended up getting it working with a version that was unaltered from original.

sudo nano /opt/netdata/etc/netdata/exporting.conf

[exporting:global]
    enabled = yes

[opentsdb:yunohost]
    enabled = yes
    destination = localhost:4242
    # data source = average
    # prefix = netdata
    # hostname = my_hostname
    update every = 60
    # buffer on failures = 10
    # timeout ms = 20000
    # send names instead of ids = yes
    # send charts matching = *
    # send hosts matching = localhost *

the working version of my influxdb.conf looks like this

[[opentsdb]]                                                                                                                                                                                                     
  #  enabled = true                                                                                                                                                                                              
  #  bind-address = ":4242"

  # consistency-level = "one"

Thanks @ColonelBuendia it worked!
You also have to restart netdata, influxdb and grafana-server services after creating the /opt/netdata/etc/netdata/exporting.conf file:

systemctl restart netdata
systemctl restart influxdb
systemctl restart grafana-server

[Quiwy]

I found that exporting.conf didn't exist for me in the netdata conf section.

sudo nano /opt/netdata/etc/netdata/exporting.conf

[exporting:global]
    enabled = yes

[opentsdb:yunohost]
    enabled = yes
    destination = localhost:4242
    # data source = average
    # prefix = netdata
    # hostname = my_hostname
    update every = 60
    # buffer on failures = 10
    # timeout ms = 20000
    # send names instead of ids = yes
    # send charts matching = *
    # send hosts matching = localhost *

Thank you @ColonelBuendia I missed that part when I read the install script line by line to see if something was missing, I now have data on my graphs 😃
Don't know what went wrong during installation 😞

[nathanael-h]

I confirm it works also for me: big thanks to @ColonelBuendia !!!! 👏 🎆 🥳 🍻 😄

Hi, it would help to keep the issue open if it's supposed to work out of the box, at least until #26 is merged. Makes it easier to find the solution.

Also, I changed the influxdb config and enabled the opentsdb, if anyone else struggles.
