I am working on an application that sends logs to GCP StackDriver. I want to put custom "tags" (or summary fields) natively on my log entry. I am looking for a solution that doesn't rely on defining custom summary fields in the console, as those are not permanent, and not project-wide.
I realized that some logger have tags displayed. For example, GCF logs will show its execution_id. Using the following snippet, I can verify that the tags displayed depend on the name of the logger:
from google.cloud import logging
client = logging.Client()
client.logger(name="custom").log_text("foobar", labels={"execution_id": "foo"})
client.logger(name="cloudfunctions.googleapis.com%2Fcloud-functions").log_text("foobar", labels={"execution_id": "foo"})
if you filter your logs on "foobar", you will see that only the second entry has "foo" as a tag.
That tag matches the label.execution_id specified in the code. The problem is, I cannot add custom labels, if I add another label that is not execution_id, it is not displayed as a tag (but still found in the log body).
It looks like each monitored resources has its own set of tag, ie: BigQuery resources use protoPayload.authenticationInfo.principalEmail as tag. But I cannot find a way to specify my own resources.
Does anybody has some experience with that kind of issue?
Thanks in advance
