Dieter Plaetinck	cda025b5b5	TSDB: demistify SeriesRefs and ChunkRefs (#9536 ) * TSDB: demistify seriesRefs and ChunkRefs The TSDB package contains many types of series and chunk references, all shrouded in uint types. Often the same uint value may actually mean one of different types, in non-obvious ways. This PR aims to clarify the code and help navigating to relevant docs, usage, etc much quicker. Concretely: * Use appropriately named types and document their semantics and relations. * Make multiplexing and demuxing of types explicit (on the boundaries between concrete implementations and generic interfaces). * Casting between different types should be free. None of the changes should have any impact on how the code runs.

Robert Fratto	bc72a718c4	Initial draft of prometheus-agent (#8785 ) * Initial draft of prometheus-agent This commit introduces a new binary, prometheus-agent, based on the Grafana Agent code. It runs a WAL-only version of prometheus without the TSDB, alerting, or rule evaluations. It is intended to be used to remote_write to Prometheus or another remote_write receiver. By default, prometheus-agent will listen on port 9095 to not collide with the prometheus default of 9090. Truncation of the WAL cooperates on a best-effort case with Remote Write. Every time the WAL is truncated, the minimum timestamp of data to truncate is determined by the lowest sent timestamp of all samples across all remote_write endpoints. This gives loose guarantees that data from the WAL will not try to be removed until the maximum sample lifetime passes or remote_write starts functionining.

Tom Wilkie	7369561305	Combine Appender.Add and AddFast into a single Append method. (#8489 ) This moves the label lookup into TSDB, whilst still keeping the cached-ref optimisation for repeated Appends. This makes the API easier to consume and implement. In particular this change is motivated by the scrape-time-aggregation work, which I don't think is possible to implement without it as it needs access to label values.

Chris Marchbanks	dfad1da296	Remove duplicate metrics in QueueManager Right now any new metrics added for remote write need to be added to both the QueueManager struct, and the queueManagerMetrics struct. Instead, use the queueManagerMetrics struct directly from QueueManager. The newQueueManagerMetrics constructor will now create the metrics for a specific queue with name and endpoint pre-populated, and a new copy of the struct will be created specifically for each queue. This also fixes a bug where prometheus_remote_storage_sent_bytes_total is not being unregistered after a queue is changed. Signed-off-by: Chris Marchbanks <csmarchbanks@gmail.com>	5 years ago

Bartlomiej Plotka	34426766d8	Unify Iterator interfaces. All point to storage now. This is part of https://github.com/prometheus/prometheus/pull/5882 that can be done to simplify things. All todos I added will be fixed in follow up PRs. * querier.Querier, querier.Appender, querier.SeriesSet, and querier.Series interfaces merged with storage interface.go. All imports that. * querier.SeriesIterator replaced by chunkenc.Iterator * Added chunkenc.Iterator.Seek method and tests for xor implementation (?) * Since we properly handle SelectParams for Select methods I adjusted min max based on that. This should help in terms of performance for queries with functions like offset. * added Seek to deletedIterator and test. * storage/tsdb was removed as it was only a unnecessary glue with incompatible structs.

Callum Styan	6f69e31398	Tail the TSDB WAL for remote_write This change switches the remote_write API to use the TSDB WAL. This should reduce memory usage and prevent sample loss when the remote end point is down. We use the new LiveReader from TSDB to tail WAL segments. Logic for finding the tracking segment is included in this PR. The WAL is tailed once for each remote_write endpoint specified. Reading from the segment is based on a ticker rather than relying on fsnotify write events, which were found to be complicated and unreliable in early prototypes. Enqueuing a sample for sending via remote_write can now block, to provide back pressure. Queues are still required to acheive parallelism and batching. We have updated the queue config based on new defaults for queue capacity and pending samples values - much smaller values are now possible. The remote_write resharding code has been updated to prevent deadlocks, and extra tests have been added for these cases. As part of this change, we attempt to guarantee that samples are not lost; however this initial version doesn't guarantee this across Prometheus restarts or non-retryable errors from the remote end (eg 400s). This changes also includes the following optimisations: - only marshal the proto request once, not once per retry - maintain a single copy of the labels for given series to reduce GC pressure Other minor tweaks: - only reshard if we've also successfully sent recently - add pending samples, latest sent timestamp, WAL events processed metrics Co-authored-by: Chris Marchbanks <csmarchbanks.com> (initial prototype) Co-authored-by: Tom Wilkie <tom.wilkie@gmail.com> (sharding changes) Signed-off-by: Callum Styan <callumstyan@gmail.com>	6 years ago
