Justin Lei	8ef7dfdeeb	Add a chunk size limit in bytes (#12054 ) Add a chunk size limit in bytes This creates a hard cap for XOR chunks of 1024 bytes. The limit for histogram chunk is also 1024 bytes, but it is a soft limit as a histogram has a dynamic size, and even a single one could be larger than 1024 bytes. This also avoids cutting new histogram chunks if the existing chunk has fewer than 10 histograms yet. In that way, we are accepting "jumbo chunks" in order to have at least 10 histograms in a chunk, allowing compression to kick in. Signed-off-by: Justin Lei <justin.lei@grafana.com>	1 year ago
Robert Fratto	886945cda7	tsdb/agent: ensure that new series get written to WAL on rollback (#12592 ) If a new series is introduced in a storage.Appender instance, that series should be written to the WAL once the storage.Appender is closed, even on Rollback. Previously, new series would only be written to the WAL when calling Commit. However, because the series is stored in memory regardless, subsequent calls to Commit may write samples to the WAL which reference a series ID which that was never written. Related to #11589. It's likely that this fix also resolves this issue, but we need more testing from users to see if the problem persists after this fix; there may be more cases where samples get written to the WAL in Prometheus Agent mode without the corresponding series record.

beorn7	817a2396cb	Name float values as "floats", not as "values" In the past, every sample value was a float, so it was fine to call a variable holding such a float "value" or "sample". With native histograms, a sample might have a histogram value. And a histogram value is still a value. Calling a float value just "value" or "sample" or "V" is therefore misleading. Over the last few commits, I already renamed many variables, but this cleans up a few more places where the changes are more invasive. Note that we do not to attempt naming in the JSON APIs or in the protobufs. That would be quite a disruption. However, internally, we can call variables as we want, and we should go with the option of avoiding misunderstandings. Signed-off-by: beorn7 <beorn@grafana.com>	2 years ago

Bryan Boreham	4b9f248e85	unit tests: make all Labels sorted alphabetically (#10532 ) "Labels is a sorted set of labels. Order has to be guaranteed upon instantiation." says the comment, so fix all the tests that break this rule. For `BenchmarkLabelValuesWithMatchers()` and `BenchmarkHeadLabelValuesWithMatchers()` the amount of work done changes significantly if you put the labels in order, because all series refs get neatly partitioned by the `tens` label, so I renamed the labels to maintain the previous behaviour.

Robert Fratto	286dfc70b7	tsdb/agent: port grafana/agent#676 (#10587 ) * tsdb/agent: port grafana/agent#676 grafana/agent#676 fixed an issue where a loading a WAL with multiple segments may result in ref ID collision. The starting ref ID for new series should be set to the highest ref ID across all series records from all WAL segments. This fixes an issue where the starting ref ID was incorrectly set to the highest ref ID found in the newest segment, which may not have any ref IDs at all if no series records have been appended to it yet.

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.
