I have the same problem. This error log begins showing once I set the archive-policy granularity to 3s as well as setting the polling interval in ceilometer to 3 seconds. This error never showing days before when the granularity and the polling interval is both at 3600s
I think the cause is because some of the metrics has zero value, or perhaps because of the error it became zero? gnocchi aggregates '(/ (aggregate rate:mean (metric cpu mean)) 3000000000)' id=65592309-1e03-4c9e-8696-af7ebe30583c | tail | aggregated | 2021-03-31T21:16:48+00:00 | 3.0 | 0.0 | | aggregated | 2021-03-31T21:16:54+00:00 | 3.0 | 0.01 | | aggregated | 2021-03-31T21:16:57+00:00 | 3.0 | 0.006666666666666667 | | aggregated | 2021-03-31T21:17:00+00:00 | 3.0 | 0.006666666666666667 | | aggregated | 2021-03-31T21:17:03+00:00 | 3.0 | 0.0033333333333333335 | | aggregated | 2021-03-31T21:17:09+00:00 | 3.0 | 0.008333333333333333 | | aggregated | 2021-03-31T21:17:12+00:00 | 3.0 | 0.008333333333333333 | | aggregated | 2021-03-31T21:17:15+00:00 | 3.0 | 0.0 | | aggregated | 2021-03-31T21:17:18+00:00 | 3.0 | 0.01 | +------------+---------------------------+-------------+-----------------------+ Traceback (most recent call last): File "/usr/lib/python3/dist-packages/gnocchi/chef.py", line 163, in process_new_measures_for_sack self.storage.add_measures_to_metrics({ File "/usr/lib/python3/dist-packages/gnocchi/storage/__init__.py", line 675, in add_measures_to_metrics keys_and_splits_to_store) = ts.set_values( File "/usr/lib/python3/dist-packages/gnocchi/carbonara.py", line 367, in set_values return_value = before_truncate_callback(self) File "/usr/lib/python3/dist-packages/gnocchi/storage/__init__.py", line 638, in _map_compute_splits_operations tstamp = max(bound_timeserie.first, measures['timestamps'][0]) IndexError: index 0 is out of bounds for axis 0 with size 0 My installed versions : gnocchi-api/groovy,now 4.4.0-0ubuntu1 all [installed] gnocchi-common/groovy,now 4.4.0-0ubuntu1 all [installed,automatic] gnocchi-metricd/groovy,now 4.4.0-0ubuntu1 all [installed] gnocchi-statsd/groovy 4.4.0-0ubuntu1 all -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1857175 Title: IndexError: index is out of bounds for axis with size To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnocchi/+bug/1857175/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
