Mixing
Writing OpenTSDB to Bigtable with HTTP POST not working (using Kubernetes(
Updated with more information
I am trying to set up OpenTSDB on Bigtable, following this guide:
https://cloud.google.com/solutions/opentsdb-cloud-platform
Works well, all good.
Now I was trying to open the opentsdb-write service with a LoadBalancer (type). Seems to work well, too.
Note: using a GCP load balancer.
I am then using insomnia to send a POST to the ./api/put endpoint - and I get a 204 as expected (also, using the ?details shows no errors, neither does the ?sync) (see http://opentsdb.net/docs/build/html/api_http/put.html)
When querying the data (GET on ./api/query), I don't see the data (same effect in grafana). Also, I do not see any data added in the tsdb table in bigtable.
My conclusion: no data is written to Bigtable, although tsd is returning 204.
Interesting fact: the metric is created (I can see it in Bigtable (cbt read tsdb-uid) and also the autocomplete in the opentsdb-ui (and grafana) pick the metric up right away. But no data.
When I use the Heapster-Example as in the tutorial, it all works.
And the interesting part (to me):
NOTE: It happened a few times, with massive delay or after stoping/restarting the kubernetes cluster, that the data appeared. Suddenly. I could not reproduce as of now.
I must be missing something really simple.
Note: I don't see any errors in the logs (stackdriver) and UI (opentsdb UI), neither bigtable, nor Kubernetes, nor anything I can think of.
Note: the configs I am using are as linked in the tutorial.
The put I am using (see the 204):
and if I add ?details, it indicates success:

We had the somewhat same error and found that when writing a metric around 25 times it somehow magically appears. But we haven't found the issue yet.

thanks for the comment @dbanck - I just found the same, must be held back somewhere. As soon as it has some 10 datapoints, it writes them to bigtable. So far, I couldn't see (1.) that data is lost in the process and (2.) how to solve it. Will investigate some more

My guess is that this relates to the opentsdb flush frequency. When a tsdb cluster is shutdown, there's an automatic flush. I'm not 100% sure, but I think that the tsd.storage.flush_interval configuration manages that process.
You can reach the team that maintains the libraries via the google-cloud-bigtable-discuss group, which you can get to from the Cloud Bigtable support page for more nuanced discussions.
As an FYI, we (Google) are actively updating the https://cloud.google.com/solutions/opentsdb-cloud-platform to the latest versions of OpenTSDB and AsyncBigtable which should improve performance at high volumes.
