Tom Wilkie	ece12bff93	Shard/parrallelise samples by fingerprint in StorageQueueManager ... By splitting the single queue into multiple queues and flushing each individual queue in serially (and all queues in parallel), we can guarantee to preserve the order of timestampsin samples sent to downstream systems.	9 years ago
Julius Volz	aa3f2b7216	Generic write cleanups and changes. ... - fold metric name into labels - return initialization errors back to main - add snappy compression - better context handling - pre-allocation of labels - remove generic naming - other cleanups	9 years ago
Brian Brazil	36d2c4bd0b	Add generic write path using grpc. ... This uses a new proto format, with scope for multiple samples per timeseries in future. This will allow users to pump samples out to whatever they like without having to change the core Prometheus code. There's also an example receiver to save users figuring out the boilerplate themselves.	9 years ago

beorn7	ec08c9a391	Rework the way to communicate backpressure (AKA suspended ingestion) ... This gives up on the idea to communicate throuh the Append() call (by either not returning as it is now or returning an error as suggested/explored elsewhere). Here I have added a Throttled() call, which has the advantage that it can be called before a whole _batch_ of Append()'s. Scrapes will happen completely or not at all. Same for rule group evaluations. That's a highly desired behavior (as discussed elsewhere). The code is even simpler now as the whole ingestion buffer could be removed. Logging of throttled mode has been streamlined and will create at most one message per minute.	10 years ago
Corentin Chary	a2e4439086	Add support for remote storage on Graphite ... Allows to use graphite over tcp or udp. Metrics labels and values are used to construct a valid Graphite path in a way that will allow us to eventually read them back and reconstruct the metrics. For example, this metric: model.Metric{ model.MetricNameLabel: "test:metric", "testlabel": "test:value", "testlabel2": "test:value", ) Will become: test:metric.testlabel=test:value.testlabel2=test:value escape.go takes care of escaping values to match Graphite character set, it basically uses percent-encoding as a fallback wich will work pretty will in the graphite/grafana world. The remote storage module also has an optional 'prefix' parameter to prefix all metrics with a path (for example, 'prometheus.'). Graphite URLs are simply in the form tcp://host:port or udp://host:port.	10 years ago

Julius Volz	eeb1da36ac	Fix InfluxDB write support to work with InfluxDB 0.9.x. ... Because the InfluxDB client library currently pulls in multiple MBs of unnecessary dependencies, I have modified and cut up the vendored version to only pull in the few pieces that are actually needed. On InfluxDB's side, this dependency issue is tracked in: https://github.com/influxdb/influxdb/issues/3447 Hopefully, it will be resolved soon. If a password is needed for InfluxDB, it may be supplied via the INFLUXDB_PW environment variable.	10 years ago
