How do I update the resource attributes?

[lallaw8809]

I would like to update resource attributes while the python application is running, like id, transaction count, for example.

I able to add default attributes but I could not find a way to change the transactionCount.

logger_provider = LoggerProvider(
    resource= Resource.create(
        {
            "transactionCount": str(transactionCount)
        }
    )
)

I was going through the documentation or examples code api but I could not find any solution.

Could you guys help me with some example code or documentation?

There currently is no way to modify the Resource during runtime, as they are immutable as defined by the spec. You are better off modifying span/metric/log attributes instead if you are keeping track of something like transaction count.

Ok.
Thanks for the response.

@lzchen I have a similar problem. I can add the Resource attributes at start up and I understood that I cannot change it for each request for example. What I need to achieve is to add labels to my metric, for example setting the HTTP.ROUTE attribute so I can filter the metrics when using a visualization tool, like Grafana. I opened a discussion here https://github.com/open-telemetry/opentelemetry-python/discussions/3692.

Would you be able to give me some insight, please? I see that the data is available, but I didn't find a way to add it to the metric sent to Prometheus.
