otel-collector-metrics
(not sure about the latter) from the docker compose config
I adjusted the signoz collector config to:

So unsure what I am doing wrong or missing.

@Teymour How are you. trying to visualise the infra metrics? Check these dashboards - https://github.com/SigNoz/dashboards/tree/main/hostmetrics
t
@Pranay: thanks, I'll try it out right away. But it looked like the clickhouse db 
signoz_metrics
was not getting any data. But I have to double check that, will delete the clickhouse data folder first then retry.
@Pranay: importing/creating the dashboard went fine, but as I suspected there is no data landing in clickhouse. Assuming the db I should look for is 
signoz_metrics

ah, curious - are you able to get trace data from the sample app? Can you check if you are able to send data from your app to SigNoz https://signoz.io/docs/install/troubleshooting/
t
Yep, I tried that already with:
Copy code
docker run -it --rm signoz/troubleshoot checkEndpoint --endpoint=192.168.1.47:4317
2022-12-05T12:49:07.751Z	INFO	troubleshoot/main.go:28	STARTING!
2022-12-05T12:49:07.753Z	INFO	checkEndpoint/checkEndpoint.go:41	checking reachability of SigNoz endpoint
2022-12-05T12:49:07.784Z	INFO	troubleshoot/main.go:46	Successfully sent sample data to signoz ...
I suspect it's my local 
otel/opentelemetry-collector-contrib:0.66.0
collector setup that is wrong. As I understand it this collector should send data to the signoz collector via port 4317
I'll try this in the meantime:
p
@Srikanth Chekuri do you have more insights on what could be possible issue here?
t
not at my desk right now, but I have a suspicion. I assumed the image 
otel/opentelemetry-collector-contrib:0.66.0
was based on a linux box, but it's just a go executable
so I need to mount my local root volume to that container (so that hostmetrics has a the right files/folders to get the metrics from)
at least that's my assumption, will try it out next 😃
p
cool, let us know how it goes
t
@Pranay problem was that I was mounting the wrong location for the config file (for the 
otel/opentelemetry-collector-contrib
image).
I am now able to send logs and metrics from a container running 
otel/opentelemetry-collector-contrib
to the signoz collector (
signoz/signoz-otel-collector
)
I am just having problems sending resourcedetection context to the metrics. It works fine for the logs though.
as an example, looking at the clickhouse db

it's weird that the resource labels are correctly transferred for the logs, but not the metrics
p
Yeah, pretty weird. Would it be possible to create an issue for this with above details? I don't have any immediate possible solution in mind but can try to look more closely later https://github.com/SigNoz/signoz/issues/new/choose
t
sure, can do
s
Why did you get rid of this under clickhousemetrics exporter in SigNoz otel collector config?
Copy code
resource_to_telemetry_conversion:                                                                         
      enabled: true
t
ah that could be the problem then, I tried to get rid of as many options as possible to keep it as slim as possible. Might have been overzealous 😃
I'll try it with this option
is there a doc for these exporters that detail the options?
I created an issue, if the options fixes the issue (which seems likely looking at the name), I'll close it
looks good, thanks @Srikanth Chekuri!
will close the issue
