Julien Pivotto	3a7120bc07	Consul: Reduce WatchTimeout to 2m and set it as timeout for requests Signed-off-by: Julien Pivotto <roidelapluie@inuits.eu>	4 years ago
John Bampton	98a69b77d1	Fix spelling (#7512 ) Signed-off-by: John Bampton <jbampton@users.noreply.github.com>	4 years ago
Pierre Souchay	1508678001	Use 10m timeouts for watches (#7423 ) use ?wait=10m will give results as fast as usual when data is changing but will perform far less requests when services do not change. On large infrastructure, this will reduce quite a lot the number of qps on Consul servers while having the same performance for freshness of results.

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.	7 years ago
