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.

Fixes #2137

Tristan Colgate-McFarlane 4d9134e6d8 Add labeldrop and labelkeep actions. (#2279) 
Introduce two new relabel actions. labeldrop, and labelkeep.
These can be used to filter the set of labels by matching regex

- labeldrop: drops all labels that match the regex
- labelkeep: drops all labels that do not match the regex

have one and the relabel semantics are clearer that way.

Tom Wilkie 4520e12440 Add HTTP Basic Auth & TLS support to the generic write path. (#1957) 
* Add config, HTTP Basic Auth and TLS support to the generic write path.

- Move generic write path configuration to the config file
- Factor out config.TLSConfig -> tlf.Config translation
- Support TLSConfig for generic remote storage
- Rename Run to Start, and make it non-blocking.
- Dedupe code in httputil for TLS config.
- Make remote queue metrics global.

Fabian Reinartz 7221228843 discovery/kubernetes: select between discovery role 
This adds `role` field to the Kubernetes SD config, which indicates
which type of Kubernetes SD should be run.
This no longer allows discovering pods and nodes with the same SD
configuration for example.
 2016-07-05 14:22:12 +02:00
Anton Tolchanov 772a3af38f Allow URLs in targets defined via a JSON file 
This enables defining `blackbox_exporter` targets (which can be URLs,
because of relabeling) in a JSON file.

Not sure if this is the best approach, but current behaviour is
inconsistent (`UnmarshalYAML` does not have this check) and breaks
officially documented way to use `blackbox_exporter`.

Configuration loading errors if both options are set.

beorn7 a7408bfb47 Unify duration parsing 
It's actually happening in several places (and for flags, we use the

Julien Dehee 061fe2f364 Support AirBnB's Smartstack Nerve client for SD 
nerve's registration format differs from serverset. With this commit
there is now a dedicated treecache file in util,
and two separate files for serverset and nerve.

Brian Brazil fd2bd81cd8 Allow all instance labels in target groups 
With the blackbox exporter, the instance label will commonly
be used for things other than hostnames so remove this restriction.
https://example.com or https://example.com/probe/me are some examples.

To prevent user error, check that urls aren't provided as targets
when there's no relabelling that could potentically fix them.

Brian Brazil 1ddf75240d config: Don't hide username, it's not secret. 
Usernames are not generally considered to be secrets,
and treating them as secrets may lead to confusion
as to how secure they are. Obscuring them also makes
debugging harder.

Will Rouesnel 7810448dbe Add proxy_url parameter to allow specifying per-job HTTP proxy servers 
Allow scrape_configs to have an optional proxy_url option which specifies
a proxy to be used for all connections to hosts in that config.

Internally this modifies the various client functions to take a *url.URL pointer
which currently must point to an HTTP proxy (but has been left open-ended to
allow the url format to be extended to support others, such as maybe SOCKS if
needed).
