| # A comma-separated list of components to run. The default value 'all' runs Loki
# in single binary mode. The value 'read' is an alias to run only read-path
# related components such as the querier and query-frontend, but all in the same
# process. The value 'write' is an alias to run only write-path related
# components such as the distributor and compactor, but all in the same process.
# Supported values: all, compactor, distributor, ingester, querier,
# query-scheduler, ingester-querier, query-frontend, index-gateway, ruler,
# table-manager, read, write. A full list of available targets can be printed
# when running Loki with the '-list-targets' command line flag.

# The amount of virtual memory in bytes to reserve as ballast in order to

# however, distort metrics, because it is counted as live memory.
