Opencensus with stackdriver - causing 'One or more TimeSeries could not be written...'

[venkatesha]

Hi all,

I am using GKE to deploy a golang app.

Using opencensus with stackdriver for tracing and metrics 

Getting the below error in logs

rpc error: code = InvalidArgument desc = One or more TimeSeries could not be written: One or more points were written more frequently than the maximum sampling period configured for the metric.: timeSeries[0-5]

any idea why this is occurring?

thanks

Are you writing points for the same timeseries that are less than 1 minute apart? See https://cloud.google.com/monitoring/custom-metrics/creating-metrics#writing-ts.

Hi Igor,

I'm not writing any custom metrics, Just integrated opencensus with my code.

I have two GCP Projects, same code is working fine(without the above error) in one but not in another.

thanks.

Opencensus and stackdriver versions

name = "contrib.go.opencensus.io/exporter/stackdriver"

version = "0.6.0"

name = "go.opencensus.io"

version = "0.15.0"

I'm facing the same thing, and its 2020.

Since we are also running in GKE, and GKE sends metrics to Stackdriver by itself, could be that having a service running in GKE with custom metrics have any kind of collision with GKE sending its own metrics?

[Igor Peshansky]

Each timeseries stream is checked separately, so if you are writing a different metric type, or against a different target, or with different labels, its points will be completely independent from any other stream.

You should be able to use the OpenCensus agent [1][2] to dump the requests sent to Cloud Monitoring and find out which timeseries are written in each request. There aren't enough details here for us to help you further. We would need to know what metrics are being written, and maybe see a sample request that produces the RPC error.
