Corentin Chary	60dafd425c	consul: improve consul service discovery (#3814) ... * consul: improve consul service discovery Related to #3711 - Add the ability to filter by tag and node-meta in an efficient way (`/catalog/services` allow filtering by node-meta, and returns a `map[string]string` or `service`->`tags`). Tags and nore-meta are also used in `/catalog/service` requests. - Do not require a call to the catalog if services are specified by name. This is important because on large cluster `/catalog/services` changes all the time. - Add `allow_stale` configuration option to do stale reads. Non-stale reads can be costly, even more when you are doing them to a remote datacenter with 10k+ targets over WAN (which is common for federation). - Add `refresh_interval` to minimize the strain on the catalog and on the service endpoint. This is needed because of that kind of behavior from consul: https://github.com/hashicorp/consul/issues/3712 and because a catalog on a large cluster would basically change *all* the time. No need to discover targets in 1sec if we scrape them every minute. - Added plenty of unit tests. Benchmarks ---------- ```yaml scrape_configs: - job_name: prometheus scrape_interval: 60s static_configs: - targets: ["127.0.0.1:9090"] - job_name: "observability-by-tag" scrape_interval: "60s" metrics_path: "/metrics" consul_sd_configs: - server: consul.service.par.consul.prod.crto.in:8500 tag: marathon-user-observability # Used in After refresh_interval: 30s # Used in After+delay relabel_configs: - source_labels: [__meta_consul_tags] regex: ^(.*,)?marathon-user-observability(,.*)?$ action: keep - job_name: "observability-by-name" scrape_interval: "60s" metrics_path: "/metrics" consul_sd_configs: - server: consul.service.par.consul.prod.crto.in:8500 services: - observability-cerebro - observability-portal-web - job_name: "fake-fake-fake" scrape_interval: "15s" metrics_path: "/metrics" consul_sd_configs: - server: consul.service.par.consul.prod.crto.in:8500 services: - fake-fake-fake ``` Note: tested with ~1200 services, ~5000 nodes. | Resource | Empty | Before | After | After + delay | | -------- |:-----:|:------:|:-----:|:-------------:| |/service-discovery size|5K|85MiB|27k|27k|27k| |`go_memstats_heap_objects`|100k|1M|120k|110k| |`go_memstats_heap_alloc_bytes`|24MB|150MB|28MB|27MB| |`rate(go_memstats_alloc_bytes_total[5m])`|0.2MB/s|28MB/s|2MB/s|0.3MB/s| |`rate(process_cpu_seconds_total[5m])`|0.1%|15%|2%|0.01%| |`process_open_fds`|16|*1236*|22|22| |`rate(prometheus_sd_consul_rpc_duration_seconds_count{call="services"}[5m])`|~0|1|1|*0.03*| |`rate(prometheus_sd_consul_rpc_duration_seconds_count{call="service"}[5m])`|0.1|*80*|0.5|0.5| |`prometheus_target_sync_length_seconds{quantile="0.9",scrape_job="observability-by-tag"}`|N/A|200ms|0.2ms|0.2ms| |Network bandwidth|~10kbps|~2.8Mbps|~1.6Mbps|~10kbps| Filtering by tag using relabel_configs uses **100kiB and 23kiB/s per service per job** and quite a lot of CPU. Also sends and additional *1Mbps* of traffic to consul. Being a little bit smarter about this reduces the overhead quite a lot. Limiting the number of `/catalog/services` queries per second almost removes the overhead of service discovery. * consul: tweak `refresh_interval` behavior `refresh_interval` now does what is advertised in the documentation, there won't be more that one update per `refresh_interval`. It now defaults to 30s (which was also the current waitTime in the consul query). This also make sure we don't wait another 30s if we already waited 29s in the blocking call by substracting the number of elapsed seconds. Hopefully this will do what people expect it does and will be safer for existing consul infrastructures.	8 years ago

Simon Pasquier	83325c8d82	web: replace deprecated InstrumentHandler() (#3862) ... * web: replace deprecated InstrumentHandler() This change replaces the deprecated InstrumentHandler function by the equivalent functions from the promhttp package. The following metrics are removed: * http_request_duration_microseconds (Summary). * http_request_size_bytes (Summary). * http_requests_total (Counter). And the following metrics are added instead: * prometheus_http_request_duration_seconds (Histogram). * prometheus_http_response_size_bytes (Histogram). * promhttp_metric_handler_requests_in_flight (Gauge). * promhttp_metric_handler_requests_total (Counter). * Update github.com/prometheus/common/route package * web: refactor using the new prometheus/common/route package	8 years ago

James Turnbull	4486ef013b	Make show annotations checkbox match query history checkbox (#3936) ... After removing the checkbox in #3913 the only remaining element that looked like it was the new Show Annotations checkbox on the Alerts page. Which in turn didn't look like the Enable query history checkout on the graph page. So: 1. This takes the Enable query history button as canonical. 2. Updates the show annotations button code to match it. 3. Simplifies the JS for the checkbox.	8 years ago

Matt Palmer	042090a6d3	[dns_sd] Send an EDNS0 query by default (#3586) ... Based on https://groups.google.com/d/topic/prometheus-users/02kezHbuea4/discussion Does not attempt to handle a situation where the server does not understand EDNS0, however that is an unlikely case, and the behaviour of such ancient systems is hard to predict in advance, so if it does come up, it will need to be handled on a case-by-case basis.	8 years ago
James Turnbull	c3f4f2204f	Refactor/redesign Unhealthy checkbox on Targets page (#3913) ... * Added only healthy to Targets This adds a "Only heathly" button to supplement the "Only unhealthy" button. The two are mutually exclusive. I've also added a red/green text color to the buttons. Arguably this could be a toggle instead if folks think this is worthwhile... Happy to modify it. * Moved functions above init * Simplifed code and made prettier * Appeased codeacy * Made buttons square	8 years ago
