I created a graph based on avg_over_time<https://prometheus.io/docs/prometheus/latest/querying/functions/#aggregation_over_time> with 1hr and 5m interval. looking at the graph you can see that it has high spikes which doesn't make sense (IMO) how can the average have those spikes ? after all since I do not delete keys I would expect to go up or remain the same. any ideas what can explain such behaviour ? attached are graphs 5m and 1 h intervals [Screen Shot 2019-03-10 at 13.37.44.png] [Screen Shot 2019-03-10 at 13.33.40.png]
