Ed Welch	79c5fdd9c0	Canary: Refactor how the direct Canary push works (#9569) ... **What this PR does / why we need it**: When doing some testing a while back I ran into several cases were we didn't handle errors/retries properly in the code we added for the canaries to send directly to Loki. The changes here effectively duplicate the way promtail's client does sends to Loki which is code we've been using/relying on for years now. I also had a hard time following the previous implementation which used the io.Writer interface for swapping out writing to stdout vs pushing to Loki and refactored this to use a new interface `EntryWriter` which has implementations that write to stdout and to Loki Unfortunately the changes in the diff don't read super well with this refactoring so hopefully the explanation helps. **Which issue(s) this PR fixes**: Fixes #<issue number> **Special notes for your reviewer**: **Checklist** - [x] Reviewed the [`CONTRIBUTING.md`](https://github.com/grafana/loki/blob/main/CONTRIBUTING.md) guide (**required**) - [ ] Documentation added - [ ] Tests updated - [ ] `CHANGELOG.md` updated - [ ] Changes that require user attention or interaction to upgrade are documented in `docs/sources/upgrading/_index.md` - [ ] For Helm chart changes bump the Helm chart version in `production/helm/loki/Chart.yaml` and update `production/helm/loki/CHANGELOG.md` and `production/helm/loki/README.md`.

We had a global singleton of the tsdb.Store which was leading to the migrate tool reading from and writing to the `source` storage.Store because it created the singleton with an object store client only pointing to the source store.

Bill Franklin	3ed9f0c9ef	Canary: support filtering / parsing logs with LogQL (#8871) ... **What this PR does / why we need it**: The canary logs can be shipped to Loki in various formats. This allows users of the canary to parse out the canaries logs from any format e.g. nested json. The alternative is to do something different for the canary logs to prevent the logs being wrapped / manipulated (e.g. write to Loki directly, or use a different log pipeline) which limits the benefits of the canary. I've confirmed this works locally. **Which issue(s) this PR fixes**: Fixes #7775 **Checklist** - [x] Reviewed the [`CONTRIBUTING.md`](https://github.com/grafana/loki/blob/main/CONTRIBUTING.md) guide (**required**) - [ ] Documentation added - [ ] Tests updated - [ ] `CHANGELOG.md` updated - [ ] Changes that require user attention or interaction to upgrade are documented in `docs/sources/upgrading/_index.md`	2 years ago

The relevant change introduced support for configuring a new `LOKI_ADDRESS` canary environment variable by adopting a new library for flags.

Danny Kopping	6bf5b5d8c1	Use a line-buffered logger to deamplify write syscalls (#6954) ... We initialise a global logger in `pkg/util/log/log.go` and use it extensively throughout the Loki codebase. Every time we write a log message, a `write` syscall is invoked. Syscalls are problematic because they transition the process from userspace to kernelspace, which means: - a context-switch is incurred, which is inherently expensive ([1-2 microseconds](https://eli.thegreenplace.net/2018/measuring-context-switching-and-memory-overheads-for-linux-threads/)) - the goroutine executing the code is **blocked** - the underlying OS thread (_M_ in the go scheduler model) is **also blocked** - the goroutine has to be rescheduled once the syscall exits - the go scheduler may need to spawn additional OS threads if all are blocked in syscalls - which can also be expensive This change introduces the use of a line-buffered logger. It has a buffer of [256](https://gist.github.com/dannykopping/0704db32c0b08751d1d2494efaa734c2) entries, and once that buffer is filled it will flush to disk. However, a situation will arise in which that buffer remains somewhat empty for a period of time, so there is a periodic flush mechanism, configured to flush every 100ms. There is also a preallocated bytes slice of 10MB which is reused, to avoid excessive slice resizing & garbage collection. This does mean that we could lose up to 256 log messages in case of an ungraceful termination of the process, but this would need to be precisely timed within the 100ms flushes - in other words, the likelihood is low, and generally we shouldn't `kill -9` any Loki process.	3 years ago

Kaviraj Kanagaraj	2c9fa05c29	feat(loki-canary): Add support to push logs directly to Loki. (#7063) ... Add additional `push` mode to loki-canary, which pushes the logs directly to given Loki URL as it generates logs. The real function of Loki Canary is to act like a tenant and help us know the whether Loki installation is working as perceived by a real tenant. Main rationale for this additional push mode is to make canary more standalone without needing for `promtail` (or `grafana-agent`) to scrape it's logs and send to loki, with this change, Loki canary happily tests Loki behavior without needing any other dependencies. **NOTES**: 1. If you run Loki behind any proxy that has different authorization policies to READ or WRITE to Loki, then important change that canary operator need to be aware of it, now the user credentials they pass via `-user` and `-pass` to access loki endpoints need to have both `read' and `write` permissions (previously canary just query the logs where as promtail is the one pushes the logs, so just READ permissions was sufficient). 2. There will be follow up PR(s) to cleanup, particularly `reader` and `comparitor` component in terms of logging with proper logger. Rationale is to keep the changes small per PR to make it easy to review. 3. This changes were tested it in one of the internal Loki dev cell. 4. **This PR is a no-op if this new `push` flag is disabled (it's disabled by default)** Signed-off-by: Kaviraj <kavirajkanagaraj@gmail.com> Co-authored-by: Danny Kopping <danny.kopping@grafana.com>	3 years ago
