Cyril Tovena	7654c27c12	Adds configurable compression algorithms for chunks (#1411) ... * Adds L4Z encoding. Signed-off-by: Cyril Tovena <cyril.tovena@gmail.com> * Adds encoding benchmarks Signed-off-by: Cyril Tovena <cyril.tovena@gmail.com> * Adds snappy encoding. Signed-off-by: Cyril Tovena <cyril.tovena@gmail.com> * Adds chunk size test Signed-off-by: Cyril Tovena <cyril.tovena@gmail.com> * Adds snappy v2 Signed-off-by: Cyril Tovena <cyril.tovena@gmail.com> * Improve benchmarks Signed-off-by: Cyril Tovena <cyril.tovena@gmail.com> * Remove chunkenc Signed-off-by: Cyril Tovena <cyril.tovena@gmail.com> * Update lz4 to latest master version. Signed-off-by: Peter Štibraný <peter.stibrany@grafana.com> * Use temporary buffer in serialise method to avoid allocations when doing string -> byte conversion. It also makes code little more readable. We pool those buffers for reuse. Signed-off-by: Peter Štibraný <peter.stibrany@grafana.com> * Added gzip -1 for comparison. Signed-off-by: Peter Štibraný <peter.stibrany@grafana.com> * Initialize reader and buffered reader lazily. This helps with reader/buffered reader reuse. Signed-off-by: Peter Štibraný <peter.stibrany@grafana.com> * Don't keep entries, extracted generateData function (mostly to get more understandable profile) Signed-off-by: Peter Štibraný <peter.stibrany@grafana.com> * Improve test and benchmark to cover all encodings. Signed-off-by: Cyril Tovena <cyril.tovena@gmail.com> * Adds support for a new chunk format with encoding info. Signed-off-by: Cyril Tovena <cyril.tovena@gmail.com> * Ingesters now support encoding config. Signed-off-by: Cyril Tovena <cyril.tovena@gmail.com> * Add support for no compression. Signed-off-by: Cyril Tovena <cyril.tovena@gmail.com> * Add docs Signed-off-by: Cyril Tovena <cyril.tovena@gmail.com> * Remove default Gzip for ByteChunk. Signed-off-by: Cyril Tovena <cyril.tovena@gmail.com> * Removes none, snappyv2 and gzip-1 Signed-off-by: Cyril Tovena <cyril.tovena@gmail.com> * Move log test lines to testdata and add supported encoding stringer Signed-off-by: Cyril Tovena <cyril.tovena@gmail.com> * got linted Signed-off-by: Cyril Tovena <cyril.tovena@gmail.com>	6 years ago

Joe Elliott	b835e2082a	Fix Loki Chunks Dashboard (#1126) ... This commit cleans up the Loki Chunks dashboard either by renaming incorrectly named series or adding needed metrics. Added new metrics: - loki_ingester_memory_chunks - loki_ingester_memory_streams - loki_ingester_chunk_utilization - loki_ingester_chunk_compression_ratio The following metrics were already being published with a different name. Fixed in the dashboard: - cortex_chunk_store_index_entries_per_chunk - cortex_ingester_flush_queue_length - loki_ingester_chunk_entries	6 years ago
