*: avoid missed Alertmanager targets (#6455)
This change makes sure that nearly-identical Alertmanager configurations
aren't merged together.

The config's identifier was the MD5 hash of the configuration serialized
to JSON but because `relabel.Regexp` has no public field and doesn't
implement the JSON.Marshaler interface, it was always serialized to
"{}".

In practice, the identifier can be based on the index of the
configuration in the list.

Chris Marchbanks a6a55c433c Improve desired shards calculation (#5763)
The desired shards calculation now properly keeps track of the rate of
pending samples, and uses the previously unused integralAccumulator to
adjust for missing information in the desired shards calculation.

Also, configure more capacity for each shard.  The default 10 capacity
causes shards to block on each other while
sending remote requests. Default to a 500 sample capacity and explain in
the documentation that having more capacity will help throughput.

Callum Styan 6f69e31398 Tail the TSDB WAL for remote_write
This change switches the remote_write API to use the TSDB WAL.  This should reduce memory usage and prevent sample loss when the remote end point is down.

We use the new LiveReader from TSDB to tail WAL segments.  Logic for finding the tracking segment is included in this PR.  The WAL is tailed once for each remote_write endpoint specified. Reading from the segment is based on a ticker rather than relying on fsnotify write events, which were found to be complicated and unreliable in early prototypes.

Enqueuing a sample for sending via remote_write can now block, to provide back pressure.  Queues are still required to acheive parallelism and batching.  We have updated the queue config based on new defaults for queue capacity and pending samples values - much smaller values are now possible.  The remote_write resharding code has been updated to prevent deadlocks, and extra tests have been added for these cases.

As part of this change, we attempt to guarantee that samples are not lost; however this initial version doesn't guarantee this across Prometheus restarts or non-retryable errors from the remote end (eg 400s).

This changes also includes the following optimisations:
- only marshal the proto request once, not once per retry
- maintain a single copy of the labels for given series to reduce GC pressure

Other minor tweaks:
- only reshard if we've also successfully sent recently
- add pending samples, latest sent timestamp, WAL events processed metrics

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.

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:

      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.

|`rate(process_cpu_seconds_total[5m])`|0.1%|15%|2%|0.01%|

|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.

Thibault Chataigner bf4a279a91 Remote storage reads based on oldest timestamp in primary storage (#3129)
Currently all read queries are simply pushed to remote read clients.
This is fine, except for remote storage for wich it unefficient and
make query slower even if remote read is unnecessary.
So we need instead to compare the oldest timestamp in primary/local
storage with the query range lower boundary. If the oldest timestamp
is older than the mint parameter, then there is no need for remote read.
This is an optionnal behavior per remote read client.

Fuente, Pablo Andres 902fafb8e7 Fixing tests for Windows
Fixing the config/config_test, the discovery/file/file_test and the
promql/promql_test tests for Windows. For most of the tests, the fix involved
correct handling of path separators. In the case of the promql tests, the
issue was related to the removal of the temporal directories used by the
storage. The issue is that the RemoveAll() call returns an error when it
tries to remove a directory which is not empty, which seems to be true due to
some kind of process that is still running after closing the storage. To fix
it I added some retries to the remove of the temporal directories.

Add ability to limit scrape samples, and related metrics
2017-01-08 01:34:06 +01:00
Brian Brazil 30448286c7 Add sample_limit to scrape config.
This imposes a hard limit on the number of samples ingested from the
target. This is counted after metric relabelling, to allow dropping of
problemtic metrics.

This is intended as a very blunt tool to prevent overload due to
misbehaving targets that suddenly jump in sample count (e.g. adding
a label containing email addresses).

Add metric to track how often this happens.
