Damien Lespiau	e64037053d	Expose controller kind and name to labelling rules ... Relabelling rules can use this information to attach the name of the controller that has created a pod. In turn, this can be used to slice metrics by workload at query time, ie. "Give me all metrics that have been created by the $name Deployment" Signed-off-by: Damien Lespiau <damien@weave.works>	7 years ago

Philippe Laflamme	2aba238f31	Use common HTTPClientConfig for marathon_sd configuration (#4009) ... This adds support for basic authentication which closes #3090 The support for specifying the client timeout was removed as discussed in https://github.com/prometheus/common/pull/123. Marathon was the only sd mechanism doing this and configuring the timeout is done through `Context`. DC/OS uses a custom `Authorization` header for authenticating. This adds 2 new configuration properties to reflect this. Existing configuration files that use the bearer token will no longer work. More work is required to make this backwards compatible.	7 years ago

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

Pedro Araújo	575f665944	Add OS type meta label to Azure SD (#3863) ... There is currently no way to differentiate Windows instances from Linux ones. This is needed when you have a mix of node_exporters / wmi_exporters for OS-level metrics and you want to have them in separate scrape jobs. This change allows you to do just that. Example: ``` - job_name: 'node' azure_sd_configs: - <azure_sd_config> relabel_configs: - source_labels: [__meta_azure_machine_os_type] regex: Linux action: keep ``` The way the vendor'd AzureSDK provides to get the OsType is a bit awkward - as far as I can tell, this information can only be gotten from the startup disk. Newer versions of the SDK appear to improve this a bit (by having OS information in the InstanceView), but the current way still works.	7 years ago
