Marco Pracucci	e7fb205827	fix(logcli): timestamp timezone handling (#821) ... Logcli used to inconsistently handle timezones in timestamps. This addresses this by adding a new `--timezone` / `-z` flag, to explicitly set the timezone the timestamps shall be formatted in. Furthermore it refactors the output framework inside of logcli to test it easier. Fixes #798	7 years ago

Robert Fratto	f2bec3b0a5	promtail: restore ability to show target labels in promtail UI ... PR #791 accidentally removed the ability to use the promtail UI by removing methods from the Target interface that were only used within the HTML templates. Along with restoring the methods in the Target interface, this commit also introduces details for the JournalTarget, which currently only provides the position in the journal being tracked.	7 years ago

Robert Fratto	d34b1f7450	ingester: support chunk transfers on ingester shutdown. ... This commit introduces chunk transfers, borrowing the mechanism from Cortex's implementation: when an ingester is shut down with claim on rollout enabled, the ingester will find a pending ingester and transfer all of its chunks to it.	7 years ago

sh0rez	38cb093358	feat(loki): extended tailing (#764) ... * refactor(querier/ingester): TailRequest Lookback window Moves the specifications of the Lookback Window out of the logproto.QueryRequest into it's own type logproto.Lookback. This is required, because the Lookback Window will be used in the TailRequest as well. * feat(querier): parse Lookback from HTTP Request * feat(logcli): send Lookback Window spec with tail request * feat(querier): include historic entries in tail mode Extends tailing by sending a configurable amount of historic entries with before the live entries. This enables a behaviour that is closer to kubectl logs -f and docker logs -f. It is implemented by running a regular Query before subscribing to the ingesters. * fix: adapt tests to Lookback change * feat(querier): check all errors to make the linter happy * fix(logproto): flatten Lookback window spec Flattens the Lookback window spec into the individual queries * fix(ingester): adapt test to Lookback flatten	7 years ago

Robert Fratto	9eb3098dea	promtail: Add systemd journal support (#730) ... Support for reading systemd journal entries has been added. promtail will look for a job in scrape_configs with a journal key to activate the journal target. If GOOS=linux and CGO_ENABLED=1, promtail will now require libsystemd headers to be available for building. If GOOS is not linux or CGO_ENABLED is not 1, journal support will be unavailable and a log message will be printed warning the user that their config file has journal tailing configured without it being built into promtail. See docs/promtail-examples.md for a concrete example of using journal support. Other structural changes made: 1. Ability for checking if scrape.Config.ServiceDiscoveryConfig is non-zero has been added. This was chosen over making ServiceDiscoveryConfig a pointer as yaml.v2 cannot parse an inline struct into a pointer value. 2. Updated pipeline logger component name to journal_pipeline and file_pipeline for JournalTargetManager and FileTargetManager respectively. 3. The positions file will now store positions as strings instead of integers. Existing positions will be read in properly but written out as strings the next time the positions file is saved. This is done to be able to store the journal cursor, which is a string. The positions API has been updated to support reading in the old integer values and the new string values.	7 years ago

Edward Welch	1249e92ef3	use strconf.FormatFloat instead of fmt.Sprintf for converting floats to strings, this way we can eliminate non significant trailing zeros such that the float value 1 would be "1" as a string instead of "1.000000"	7 years ago

Edward Welch	c3084dbdc7	Removing the pre-allocation of a buffer when serializing blocks, in most of my empirical testing we were using 9-10k out of the 32k allocated leaving about 2/3 of the buffer allocated and unused times the number of blocks per chunk, times the number of chunks kept in memory. This was adding up to a fair amount of allocated but unused space.	7 years ago
