Hi, Yesterday we got a disk space warning notification on one of the monitor nodes. Most space consumption was in use by a running Loki container. Looking into online documentation / trackers to find info on Ceph's default Loki retention policy left me empty handed. I did fine some trackers for Prometheus retention policy in the past, so I figured there might be none yet. The documentation states that you can find the jinja2 templates used for the service here: src/pybind/mgr/cephadm/templates So I changed this template to include a retention policy and a compactor like: ... orig template ... compactor: working_directory: /tmp/loki/compactor shared_store: filesystem compaction_interval: 10m retention_enabled: true retention_delete_delay: 2h retention_delete_worker_count: 150 limits_config: retention_period: 2160h split_queries_by_interval: 24h ceph config-key set mgr/cephadm/services/loki/loki.yml -i $PWD/loki_with_retention_policy.yml.j2 and redeployed loki (ceph orch daemon redeploy loki.mon1). That gained a lot of free space ... as in ... all Loki logs where gone and it had started from scratch. This "/tmp/loki" working directory is ... odd? How is this supposed to work in Ceph? Thanks, Gr. Stefan
