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.

Julius Volz	a50ee8df30	Always set CORS headers at beginning of API handler. ... Change-Id: Icde9a74260c4bb919f09c3e10c6dd5f372ccdaec	11 years ago
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
Julius Volz	788587426b	Make scrape timeouts configurable per job. ... Change-Id: I77a7514ad9e7969771f873d63d6353ec50082a62	11 years ago

Matt T. Proud	a73f061d3c	Persist solely Protocol Buffers. ... An design question was open for me in the beginning was whether to serialize other types to disk, but Protocol Buffers quickly won out, which allows us to drop support for other types. This is a good start to cleaning up a lot of cruft in the storage stack and can let us eventually decouple the various moving parts into separate subsystems for easier reasoning. This commit is not strictly required, but it is a start to making the rest a lot more enjoyable to interact with.	12 years ago

Julius Volz	51689d965d	Add debug timers to instant and range queries. ... This adds timers around several query-relevant code blocks. For now, the query timer stats are only logged for queries initiated through the UI. In other cases (rule evaluations), the stats are simply thrown away. My hope is that this helps us understand where queries spend time, especially in cases where they sometimes hang for unusual amounts of time.	12 years ago
Matt T. Proud	0d2d6e9a27	Include uptime in the status console. ... In order to help corroborate whether a Prometheus instance has flapped until meta-monitoring is in-place, we ought to provide the instance's start time in the console to aid in diagnostics.	12 years ago

Matt T. Proud	1a95406b81	Include forgotten databases.html.	12 years ago
Matt T. Proud	b224251981	Simplify compaction and expose database sizes. ... This commit simplifies the way that compactions across a database's keyspace occur due to reading the LevelDB internals. Secondarily it introduces the database size estimation mechanisms. Include database health and help interfaces. Add database statistics; remove status goroutines. This commit kills the use of Go routines to expose status throughout the web components of Prometheus. It also dumps raw LevelDB status on a separate /databases endpoint.	12 years ago

Matt Proud	7f0d816574	Schedule the background compactors to run. ... This commit introduces three background compactors, which compact sparse samples together. 1. Older than five minutes is grouped together into chunks of 50 every 30 minutes. 2. Older than 60 minutes is grouped together into chunks of 250 every 50 minutes. 3. Older than one day is grouped together into chunks of 5000 every 70 minutes.	12 years ago
