Unable to export to Monitoring service because: GaxError RPC failed, caused by 3: One or more TimeSeries could not be written

[Julia Tverskaya]

I have a Python/ Django app on Flexible App Engine.

On May 16, I started receiving these messages:

Unable to export to Monitoring service because: GaxError RPC failed, caused by 3:One or more TimeSeries could not be written: Metrics cannot be written to gae_app. See https://cloud.google.com/monitoring/custom-metrics/creating-metrics#which-resource for a list of writable resource types.: timeSeries[0]

On May 18, the uptime checks for the GAE Application started to fail. This has gotten progressively worse and eventually the application had to be re-started.

I have not created any custom metrics. 

I have not made any changes to the code recently.

Questions:

1) What do the GaxError mean and how to fix them?

2) is it possible that the uptime check failures related to the  GaxErrors?

Hello,

1-This is an error from the Stackdriver logging which I have seen before but it was fixed in the past.

2-There is a possibility that both of these are related if they started happening about the same time with no change on your end.

In order to investigate further, please create a private Issue Tracker or contact Google Cloud Platform Support.

David,

I created an issue in the Issue Tracker. It's been more than two weeks, and the problem has not been addressed. Any other suggestions?

Thank you!

Hello Julia,

I realize this must be frustrating but some reasonable delays for non-paid support may occur from time to time.  Creating a Google Issue Tracker is the correct way to get assistance. If you would like an immediate response, you may choose to upgrade to a paid support with guaranteed acknowledgements cases.

I hope this helps.
