Sending Metadata and Log Entries to GCP for Vertex Call Data

Yes you could do that, If you'd like richer logs, you could export logs from portkey periodically and sync them to GCP as well

this would have additional info that portkey logs for you

The idea would be to to add some metadata to the actual vertex api calls, such as portkey reletad data. But from the google side theres seems to be no option to add data to the api calls and have that in the logs or in the metrics. So Im looking for possible alternatives

you could mqybe store that metada in portkey calls itself and later sync it to GCP, that would be easiest to implement

a cron job
