For in-cluster logging, Kyma uses Loki, a Prometheus-like log management system.
In the production profile, Loki stores up to 30 GB of data for a maximum of 5 days, with maximum ingestion rate of 3 MB/s. If the default time is exceeded, the oldest logs are removed first.
The evaluation profile has lower limits. For more information about profiles, see Install Kyma: Choose resource consumption.
