I used Helm charts for deploying Prometheus, I have persistent volume enabled, And even after cluster failures data remains, however the stored data in the persistent volume mount path cycles data after 10 days even when default retention of 15d is used, i.e., The data from day 1 gets deleted to add 11th day’s data. but retentionSize was not set. What is the default retentionSize that it goes for in this case, and why is the cycling happening in 10 days?
prometheus:
server:
persistence:
enabled: true
size: 5Gi
storageClass: standard
mountPath: /bitnami/prometheus/data
I want to make it so that the data cycles after 15 days, which is what I think happens, when retention of 15d is set, please correct this assumption if mistaken.
