Julius Volz	f1aac54104	Allow alternative "by"-clause position in grammar. In addition to the existing by-clause syntax: sum(<expression>) by (<labels>) [keeping_extra] ...this allows the following new syntax: sum by (<labels>) [keeping_extra] (<expression>) Both orderings may be used in a single expression. It is up to the users to establish guidelines around their usage. Change-Id: Iba10c9cc5fb6ac62edfcf246d281473e82467992	10 years ago
Brian Brazil	2aa8c8669e	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	50a995c8de	Don't alert() when a query is aborted, such as when you change the range. Change-Id: I574504f97446ac5f3dda737fe054ae83f17dbbc2	10 years ago
Julius Volz	080b952647	Allow omitting the metric name in queries. This allows the following expression syntaxes for selecting timeseries: foo (already valid before) foo{} (already valid before) {job="prometheus"} (new, select all timeseries for job "prometheus") Omitting both the metric name and any label matchers ("" or "{}") will still yield a syntax error. To get all timeseries, you could do: {__name__=~"."} or, without relying on knowledge about __metric__: {job=~"."} Change-Id: Ifee000b9ac0184ef6ced18411069c7f2699a2dda	10 years ago

Julius Volz	0ca5be127f	Prometheus version 0.7.0. Change-Id: I73468f72b43654f4bf57627c2f49fe802b18f637	10 years ago
Julius Volz	bfb64321de	Merge "Update used Go version to 1.3."	10 years ago
Julius Volz	ef3b512dcf	Update used Go version to 1.3. Go downloads moved to a different URL and require following redirects (curl's '-L' option) now. Go 1.3 deliberately randomizes ranges over maps, which uncovered some bugs in our tests. These are fixed too. Change-Id: Id2d9e185d8d2379a9b7b8ad5ba680024565d15f4	10 years ago
Julius Volz	b65c5dd752	Add function to drop common labels in a vector. This fixes https://github.com/prometheus/prometheus/issues/384. Change-Id: I2973c4baeb8a4618ec3875fb11c6fcf5d111784b	10 years ago
Julius Volz	f7cd18abdf	Add more topk() / bottomk() tests. Test what happens if k > number of input elements. Change-Id: Ie724b850939e297ebf085f0a5a3522e9cfcc6534	10 years ago
Julius Volz	200d02effe	Implement topk() and bottomk() functions. To achieve O(log n * k) runtime, this uses a heap to track the current bottom-k or top-k elements while iterating over the full set of available elements. It would be possible to reuse more code between topk and bottomk, but I decided for some more duplication for the sake of clarity. This fixes https://github.com/prometheus/prometheus/issues/399 Change-Id: I7487ddaadbe7acb22ca2cf2283ba6e7915f2b336	10 years ago
Bjoern Rabenstein	24ece38f7c	Make metrics exported by the Prometheus server itself more consistent. - Always spell out the time unit (e.g. milliseconds instead of ms). - Remove "_total" from the names of metrics that are not counters. - Make use of the "Namespace" and "Subsystem" fields in the options. - Removed the "capacity" facet from all metrics about channels/queues. These are all fixed via command line flags and will never change during the runtime of a process. Also, they should not be part of the same metric family. I have added separate metrics for the capacity of queues as convenience. (They will never change and are only set once.) - I left "metric_disk_latency_microseconds" unchanged, although that metric measures the latency of the storage device, even if it is not a spinning disk. "SSD" is read by many as "solid state disk", so it's not too far off. (It should be "solid state drive", of course, but "metric_drive_latency_microseconds" is probably confusing.) - Brian suggested to not mix "failure" and "success" outcome in the same metric family (distinguished by labels). For now, I left it as it is. We are touching some bigger issue here, especially as other parts in the Prometheus ecosystem are following the same principle. We still need to come to terms here and then change things consistently everywhere. Change-Id: If799458b450d18f78500f05990301c12525197d3	10 years ago
Julius Volz	ffa4a2935e	Merge "Remove backoff on scrape failure."	10 years ago
Brian Brazil	3835b7507d	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
Julius Volz	54eb21b22a	Fix time() behavior. time() should return the timestamp for which the query is executed, not the actual current time. Change-Id: I430a45cabad7785cd58f95b1028a71dff4c87710	10 years ago
Julius Volz	527831ec6e	Add abs() and over-time aggregation functions. This implements aggregation functions over time as request in https://github.com/prometheus/prometheus/issues/383. Change-Id: Ifd69b850de8cfdf6e7a6c0e042056fa4c672410e	10 years ago

Brian Brazil	7ad2cfdfbc	Add 'tmpl', a 'template' for non-string literal names. Change-Id: I6a03a5c5d20029cf414562efa7745ed6c53b2731	10 years ago
Brian Brazil	8be993b8f8	Let consoles get graph links from experssions. Rename ConsoleLinkFromExpression, as we now have consoles. Change-Id: I7ed2c9c83863adb390b51121dd9736845f7bcdfc	10 years ago
Brian Brazil	de71467758	Expose path used to get to console to console. Change-Id: I72386a2d4e53863da302ecc5c7e44d6c310197e0	11 years ago

Björn Rabenstein	443fd93536	Merge "Fix console handler."	11 years ago
Brian Brazil	61659ea733	Fix console handler. This was accidnetally broken in `2128d9d811`. Change-Id: I50ea1fdb8ae4d28ae4555410bee97e5037692aa5	11 years ago
Bjoern Rabenstein	dfb9c2a072	Remove work-around that required copying all bytes of a scrape. Now that the subtle bug in matttproud/golang_protobuf_extensions is fixed, we do not need to copy the bytes of a scrape into a buffer first before starting to parse it. Change-Id: Ib73ecae16173ddd219cda56388a8f853332f8853	11 years ago
Julius Volz	6b325bfbde	Prometheus version 0.6.0. Change-Id: I50f6b69cca952eedf9a62b9a8f58e0fb633a83ed	11 years ago
Julius Volz	6579dc3e40	Speed up disk flushes by removing unnecessary sort. The first sort in groupByFingerprint already ensures that all resulting sample lists contain only one fingerprint. We also already assume that all samples passed into AppendSamples (and thus groupByFingerprint) are chronologically sorted within each fingerprint. The extra chronological sort is thus superfluous. Furthermore, this second sort didn't only sort chronologically, but also compared all metric fingerprints again (although we already know that we're only sorting within samples for the same fingerprint). This caused a huge memory and runtime overhead. In a heavily loaded real Prometheus, this brought down disk flush times from ~9 minutes to ~1 minute.

Julius Volz	9410f15a73	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	2128d9d811	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

Brian Brazil	9c81f2e82a	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	11 years ago
Brian Brazil	fce3873b02	Add humanizeDuration function. This attempts to reasonably handle things from weekly cronjobs, to rpcs taking ns to things that are usually ms but jump to over a second. For consistency, stop putting spaces before prefixes. Change-Id: I6407879187b25680b323cd70254e205315b5fc3c	11 years ago
Julius Volz	859c3b071d	Merge "Use html/template for console templates and add template libary support."	11 years ago
Brian Brazil	29cf4d6ad9	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	11 years ago
Brian Brazil	5e6ab627df	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	11 years ago
Brian Brazil	6003cdbae0	Add title and match functions. Change-Id: Ifd376c2935e22d378e7afa06122642847a237d78	11 years ago
