Hi,

in my test deployment I get following error messages for each metric at each metric collection (every 60s in my case). Of course whole URL (i.e. /v2.0/metrics/statistics?name=transfer.region2.size&merge_metrics=True&dimensions=project_id%3Afcfaxxxxx&start_time=2021-10-31+02%3A55%3A00%2B02%3A00&end_time=2021-10-31+02%3A00%3A00%2B01%3A00&period=-3300&statistics=avg&group_by=project_id&group_by=resource_id)  is longer than 255 characters, but shouldn’t this URL be processed in smaller chunks? As I see the validation is done by monasca_api, so in case it fails no data is processed by monasca_log_transformer, right? Limiting metric name lenght won’t change this situation (in this example metric name is 22 characters long, while the whole URL is 285 characters long, so 285-22 is still > 255).

How can I avoid this error?
Best regards

Adam Tomas
