Thibault Chataigner	bf4a279a91	Remote storage reads based on oldest timestamp in primary storage (#3129 ) Currently all read queries are simply pushed to remote read clients. This is fine, except for remote storage for wich it unefficient and make query slower even if remote read is unnecessary. So we need instead to compare the oldest timestamp in primary/local storage with the query range lower boundary. If the oldest timestamp is older than the mint parameter, then there is no need for remote read. This is an optionnal behavior per remote read client.

Mathieu Pasquet	38afa507bb	Provide better errors messages in commandline Instead or only printing the help message, which is not always helpful. For example, when upgrading from prometheus v1, the retention time value format has changed and now only accepts one unit (e.g. "15d") where it previously allowed more complex strings (e.g. "360h0m0s"). This commit provides the error message as an explanation for the parsing failure.	7 years ago

Paul Gier	08af129b4d	cmd/prometheus: don't allow quotes at beginning or end of url This prevents accidental copy/paste error where a the web.external-url or alertmanager.url params could have an extra set of quotes. See also: https://github.com/prometheus/prometheus/issues/1229	7 years ago
Paul Gier	f79b55d057	cmd/prometheus: remove govalidator for url validation The usage of govalidator is redundant with the call to url.Parse for url validation. Removing it has the following benefits: - The explicit error message is displayed instead of just a generic valid/invalid message - Slightly smaller code with one fewer external dependency - Speed improvement by removing duplicate call to url.Parse (inside govalidator.IsURL() - Resolves issue #2717 The only potential drawback of removing govalidator is that certain URLs will be considered valid which were previously invalid. For example: - URLs with hostnames that start and/or end with an underscore (http://_example.com_) - URLs with hostnames that contain some special characters (http://foo&*bar.org) These are valid URIs according to RFC 3986 and valid domain names per RFC 2181, however they are not valid hostnames per RFC 952.	7 years ago

Mark Adams	77c816b309	Fix pprof endpoints when -web.route-prefix or -web.external-url is used (#3054 ) Whenever a route prefix is applied, the router prepends the prefix to the URL path on the request. For most handlers, this is not an issue because the request's path is only used for routing and is not actually needed by the handler itself. However, Prometheus delegates the handling of the /debug/* endpoints to the http.DefaultServeMux which has it's own routing logic that depends on the url.Path. As a result, whenever a prefix is applied, the prefixed URL is passed to the DefaultServeMux which has no awareness of the prefix and returns a 404. This change fixes the issue by creating a new serveDebug handler which routes requests /debug/* requests to appropriate net/http/pprof handler and removing the net/http/pprof import in cmd/prometheus since it is no longer necessary. Fixes #2183.	7 years ago

beorn7	434ab2a6a3	storage: Evict chunks and calculate persistence pressure based on target heap size This is a fairly easy attempt to dynamically evict chunks based on the heap size. A target heap size has to be set as a command line flage, so that users can essentially say "utilize 4GiB of RAM, and please don't OOM". The -storage.local.max-chunks-to-persist and -storage.local.memory-chunks flags are deprecated by this change. Backwards compatibility is provided by ignoring -storage.local.max-chunks-to-persist and use -storage.local.memory-chunks to set the new -storage.local.target-heap-size to a reasonable (and conservative) value (both with a warning). This also makes the metrics intstrumentation more consistent (in naming and implementation) and cleans up a few quirks in the tests. Answers to anticipated comments: There is a chance that Go 1.9 will allow programs better control over the Go memory management. I don't expect those changes to be in contradiction with the approach here, but I do expect them to complement them and allow them to be more precise and controlled. In any case, once those Go changes are available, this code has to be revisted. One might be tempted to let the user specify an estimated value for the RSS usage, and then internall set a target heap size of a certain fraction of that. (In my experience, 2/3 is a fairly safe bet.) However, investigations have shown that RSS size and its relation to the heap size is really really complicated. It depends on so many factors that I wouldn't even start listing them in a commit description. It depends on many circumstances and not at least on the risk trade-off of each individual user between RAM utilization and probability of OOMing during a RAM usage peak. To not add even more to the confusion, we need to stick to the well-defined number we also use in the targeting here, the sum of the sizes of heap objects.	8 years ago
beorn7	96a303b348	storage: Use staleness delta as head chunk timeout Currently, if a series stops to exist, its head chunk will be kept open for an hour. That prevents it from being persisted. Which prevents it from being evicted. Which prevents the series from being archived. Most of the time, once no sample has been added to a series within the staleness limit, we can be pretty confident that this series will not receive samples anymore. The whole chain as described above can be started after 5m instead of 1h. In the relaxed case, this doesn't change a lot as the head chunk timeout is only checked during series maintenance, and usually, a series is only maintained every six hours. However, there is the typical scenario where a large service is deployed, the deoply turns out to be bad, and then it is deployed again within minutes, and quite quickly the number of time series has tripled. That's the point where the Prometheus server is stressed and switches (rightfully) into rushed mode. In that mode, time series are processed as quickly as possible, but all of that is in vein if all of those recently ended time series cannot be persisted yet for another hour. In that scenario, this change will help most, and it's exactly the scenario where help is most desperately needed.	8 years ago
beorn7	04ccf84559	main.go: Set GOGC to 40 by default Rationale: The default value for GOGC is 100, i.e. a garbage collected is initialized once as many heap space has been allocated as was in use after the last GC was done. This ratio doesn't make a lot of sense in Prometheus, as typically about 60% of the heap is allocated for long-lived memory chunks (most of which are around for many hours if not days). Thus, short-lived heap objects are accumulated for quite some time until they finally match the large amount of memory used by bulk memory chunks and a gigantic GC cyle is invoked. With GOGC=40, we are essentially reinstating "normal" GC behavior by acknowledging that about 60% of the heap are used for long-term bulk storage. The median Prometheus production server at SoundCloud runs a GC cycle every 90 seconds. With GOGC=40, a GC cycle is run every 35 seconds (which is still not very often). However, the effective RAM usage is now reduced by about 30%. If settings are updated to utilize more RAM, the time between GC cycles goes up again (as the heap size is larger with more long-lived memory chunks, but the frequency of creating short-lived heap objects does not change). On a quite busy large Prometheus server, the timing changed from one GC run every 20s to one GC run every 12s. In the former case (just changing GOGC, leave everything else as it is), the CPU usage increases by about 10% (on a mid-size referenc server from 8.1 to 8.9). If settings are adjusted, the CPU consumptions increases more drastically (from 8 cores to 13 cores on a large reference server), despite GCs happening more rarely, presumably because a 50% larger set of memory chunks is managed now. Having more memory chunks is good in many regards, and most servers are running out of memory long before they run out of CPU cycles, so the tradeoff is overwhelmingly positive in most cases. Power users can still set the GOGC environment variable as usual, as the implementation in this commit honors an explicitly set variable.	8 years ago
