Eng Zer Jun	e2842c69c5	Replace deprecated `io/ioutil` with `io` and `os` packages (#7212 ) The `io/ioutil` package has been deprecated in Go 1.16 (See https://pkg.go.dev/io/ioutil). This PR replaces the existing `io/ioutil` functions with their new definitions in `io` and `os` packages. Signed-off-by: Eng Zer Jun <engzerjun@gmail.com>	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

Robert Fratto	f1c1097bbe	pkg/canary: use default HTTP client when reading from Loki The documentation[1] for net/http.Client says the following: A Client is an HTTP client. Its zero value (DefaultClient) is a usable client that uses DefaultTransport. The Client's Transport typically has internal state (cached TCP connections), so Clients should be reused instead of created as needed. Clients are safe for concurrent use by multiple goroutines. A Client is higher-level than a RoundTripper (such as Transport) and additionally handles HTTP details such as cookies and redirects. Canary was creating a new http.Client every time a query request was made to Loki, causing a new TCP connection to be established each time. If Loki has an outage, it's possible to get into a situation where all websocket requests are failing and for a high volume of requests to go through the normal query route. This can possibly lead to networking issues like socket starvation. [1]: https://golang.org/pkg/net/http/#Client	6 years ago
