Julius Volz	c3fcea45e3	Support finer time resolutions than 1 second. Change-Id: I4c5f1d6d2361e841999b23283d1961b1bd0c2859	10 years ago
Brian Brazil	f114bbd4e7	Make query_range more robust. Gracefully handle decimal values, by truncating them. Limit amount of steps, to avoid accidentally pulling too much data. This limit returns up to ~500kB per timeseries, and allows for 60s granularity for a week and 1h granularity for a year. Change-Id: Ie549fc24deb2eecbc6c5d1b6088a548a6b02e849	10 years ago
Brian Brazil	75e37db55b	Don't alert() when a query is aborted, such as when you change the range. Change-Id: I574504f97446ac5f3dda737fe054ae83f17dbbc2	10 years ago
Brian Brazil	fd34e4061d	Add back consoles link. Goes in index.html in consoles or else user data, if present. Change-Id: I5303d30aa24ca0c20d2e0f49121e04a260b9c4f4	10 years ago

Bjoern Rabenstein	71206dbc06	More code cleanups. Add license text everywhere. And others.... Change-Id: I11ccde267a2ef7eb366c4788ba7aeae14ba7545c	10 years ago
Bjoern Rabenstein	f5f9f3514a	Major code cleanup. - Make it go-vet and golint clean. - Add comments, TODOs, etc. Change-Id: If1392d96f3d5b4cdde597b10c8dff1769fcfabe2	10 years ago
Julius Volz	e7ed39c9a6	Initial experimental snapshot of next-gen storage. Change-Id: Ifb8709960dbedd1d9f5efd88cdd359ee9fa9d26d	10 years ago
Brian Brazil	4a2b96f848	Remove backoff on scrape failure. Having metrics with variable timestamps inconsistently spaced when things fail will make it harder to write correct rules. Update status page, requires some refactoring to insert a function. Change-Id: Ie1c586cca53b8f3b318af8c21c418873063738a8	10 years ago
Brian Brazil	f525ca5d9e	Let consoles get graph links from experssions. Rename ConsoleLinkFromExpression, as we now have consoles. Change-Id: I7ed2c9c83863adb390b51121dd9736845f7bcdfc	10 years ago
Brian Brazil	eba205fcac	Expose path used to get to console to console. Change-Id: I72386a2d4e53863da302ecc5c7e44d6c310197e0	10 years ago
Brian Brazil	eb5d928da7	Fix console handler. This was accidnetally broken in `2128d9d811`. Change-Id: I50ea1fdb8ae4d28ae4555410bee97e5037692aa5	10 years ago
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. Change-Id: I0f5393a30b88654c73567456aeaea62f8b3756d9	10 years ago
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	10 years ago
Brian Brazil	e27447da5c	Remove the broken "User Dashboard" link. Due to the lack of a </a>, this makes the entire header render badly. Accordingly it's safe to assume noone is using it, so remove it. With the new console template support, we'll need to something a bit more nuanced later. Change-Id: I3424bed6aea18cbd4c63ad48f98808098dadc3ad	10 years ago
Brian Brazil	960ede66dc	Use html/template for console templates and add template libary support. Add a function to bypass the new auto-escaping. Add a function to workaround go's templates only allowing passing in one argument. Change-Id: Id7aa3f95e7c227692dc22108388b1d9b1e2eec99	10 years ago
Brian Brazil	0f5874ff97	Make Prometheus in header link to status page. This is consistent with alertmanager, and more intiutive for users. The graphs page just has graphs, so remove mention of consoles. Change-Id: I87780a4ade33697a6095423e1a7de47d341d2838	10 years ago
Brian Brazil	1828b1f55c	Only log every query when debugging. Change-Id: I4f988d81cda6f6deb0ed7f497de4aa75409b158f	10 years ago
Brian Brazil	e041c0cd46	Add console and alert templates with access to all data. Move rulemanager to it's own package to break cicrular dependency. Make NewTestTieredStorage available to tests, remove duplication. Change-Id: I33b321245a44aa727bfc3614a7c9ae5005b34e03	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	11 years ago
Matt T. Proud	2064f32662	Clean up quitting behavior and add quit trigger. The closing of Prometheus now using a sync.Once wrapper to prevent any accidental multiple invocations of it, which could trigger corruption or a race condition. The shutdown process is made more verbose through logging. A not-enabled by default web handler has been provided to trigger a remote shutdown if requested for debugging purposes.

Julius Volz	cc04238a85	Switch to new "__name__" metric name label. This also fixes the compaction test, which before worked only because the input sample sorting was accidentally equal to the resulting on-disk sample sorting. Change-Id: I2a21c4b46ba562424b27058fc02eba84fa6a6006	11 years ago
Julius Volz	740d448983	Use custom timestamp type for sample timestamps and related code. So far we've been using Go's native time.Time for anything related to sample timestamps. Since the range of time.Time is much bigger than what we need, this has created two problems: - there could be time.Time values which were out of the range/precision of the time type that we persist to disk, therefore causing incorrectly ordered keys. One bug caused by this was: https://github.com/prometheus/prometheus/issues/367 It would be good to use a timestamp type that's more closely aligned with what the underlying storage supports. - sizeof(time.Time) is 192, while Prometheus should be ok with a single 64-bit Unix timestamp (possibly even a 32-bit one). Since we store samples in large numbers, this seriously affects memory usage. Furthermore, copying/working with the data will be faster if it's smaller. MEMORY USAGE RESULTS Initial memory usage comparisons for a running Prometheus with 1 timeseries and 100,000 samples show roughly a 13% decrease in total (VIRT) memory usage. In my tests, this advantage for some reason decreased a bit the more samples the timeseries had (to 5-7% for millions of samples). This I can't fully explain, but perhaps garbage collection issues were involved. WHEN TO USE THE NEW TIMESTAMP TYPE The new clientmodel.Timestamp type should be used whenever time calculations are either directly or indirectly related to sample timestamps. For example: - the timestamp of a sample itself - all kinds of watermarks - anything that may become or is compared to a sample timestamp (like the timestamp passed into Target.Scrape()). When to still use time.Time: - for measuring durations/times not related to sample timestamps, like duration telemetry exporting, timers that indicate how frequently to execute some action, etc. NOTE ON OPERATOR OPTIMIZATION TESTS We don't use operator optimization code anymore, but it still lives in the code as dead code. It still has tests, but I couldn't get all of them to pass with the new timestamp format. I commented out the failing cases for now, but we should probably remove the dead code soon. I just didn't want to do that in the same change as this. Change-Id: I821787414b0debe85c9fffaeb57abd453727af0f	11 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	4a87c002e8	Update low-level i'faces to reflect wireformats. This commit fixes a critique of the old storage API design, whereby the input parameters were always as raw bytes and never Protocol Buffer messages that encapsulated the data, meaning every place a read or mutation was conducted needed to manually perform said translations on its own. This is taxing. Change-Id: I4786938d0d207cefb7782bd2bd96a517eead186f	11 years ago
