Julius Volz	21cafe6cd7	Only evict memory series after they are on disk. This fixes the problem where samples become temporarily unavailable for queries while they are being flushed to disk. Although the entire flushing code could use some major refactoring, I'm explicitly trying to do the minimal change to fix the problem since there's a whole new storage implementation in the pipeline.

Bjoern Rabenstein	8956faeccb	Migrate to new client_golang. This change will only be submitted when the new client_golang has been moved to the new version. Change-Id: Ifceb59333072a08286a8ac910709a8ba2e3a1581	11 years ago
Julius Volz	01f652cb4c	Separate storage implementation from interfaces. This was initially motivated by wanting to distribute the rule checker tool under `tools/rule_checker`. However, this was not possible without also distributing the LevelDB dynamic libraries because the tool transitively depended on Levigo: rule checker -> query layer -> tiered storage layer -> leveldb This change separates external storage interfaces from the implementation (tiered storage, leveldb storage, memory storage) by putting them into separate packages: - storage/metric: public, implementation-agnostic interfaces - storage/metric/tiered: tiered storage implementation, including memory and LevelDB storage. I initially also considered splitting up the implementation into separate packages for tiered storage, memory storage, and LevelDB storage, but these are currently so intertwined that it would be another major project in itself. The query layers and most other parts of Prometheus now have notion of the storage implementation anymore and just use whatever implementation they get passed in via interfaces. The rule_checker is now a static binary :) Change-Id: I793bbf631a8648ca31790e7e772ecf9c2b92f7a0	12 years ago
Conor Hennessy	eba01d1119	Remove usage of gorest. Due to on going issues, we've decided to remove gorest. It started with gorest not being thread-safe (it does introspection to create a new handler which is an easy process to mess up with multiple threads of execution): https://code.google.com/p/gorest/issues/detail?id=15 While the issue has been marked fixed, it looks like the patch has introduced more problems than the original issue and simply doesn't work properly. I'm not sure the behaviour was thought through properly. If a new instance is needed every request then a handler-factory is needed or the library needs to set expectations about how the new objects should interact with their constructor state. While it was tempting to try out another routing library, I think for now it's better to use dumb vanilla Go routing. At least until we decide which URL format we intend to standardize on.

Matt T. Proud	3b9b1c6ab4	Define dependencies for web. stack concretely. This commit destroys the use of AppState, which makes passing concrete state along to various serving components onerous.	13 years ago
Julius Volz	f1fc7d717a	Allow replacing job targets via HTTP API. This roughly comprises the following changes: - index target pools by job instead of scrape interval - make targets within a pool exchangable while preserving existing health state for targets - allow exchanging targets via HTTP API (PUT) - show target lists in /status (experimental, for own debug use)	13 years ago

Matt T. Proud	efe61c18fa	Refactor target scheduling to separate facility. ``Target`` will be refactored down the road to support various nuanced endpoint types. Thusly incorporating the scheduling behavior within it will be problematic. To that end, the scheduling behavior has been moved into a separate assistance type to improve conciseness and testability. ``make format`` was also run.	13 years ago
