beorn7 45e5775f9b Add missing logging of out-of-order samples 
So far, out-of-order samples during rule evaluation were not logged,
and neither scrape health samples. The latter are unlikely to cause
any errors. That's why I'm logging them always now. (It's alway highly
irregular should it happen.) For rules, I have used the same plumbing
as for samples, just with a different wording in the message to mark
them as a result of rule evaluation.

beorn7 d566808d40 Bring back logging of discarded samples 
But only on DEBUG level.

Also, count and report the two cases of out-of-order timestamps on the
one hand and same timestamp but different value on the other hand
separately.

Fabian Reinartz 585ab6b163 Merge pull request #1494 from iamseth/master 
Add discovery capability for Microsoft Azure
 2016-04-21 13:49:44 +02:00
Jonathan Boulle 38098f8c95 Add missing license headers 
Prometheus is Apache 2 licensed, and most source files have the
appropriate copyright license header, but some were missing it without
apparent reason. Correct that by adding it.

Seth Miller 0988e3b937 Add support for Azure discovery

Fabian Reinartz 56fc9bdff3 Handle closed target provider channel 
This fixes the case where a target provider closes the update
channel and exits before the context is canceled.
This should only be true for the static provider but it's safer
to generally handle this case.

Fabian Reinartz 1ede7b9d72 Consolidate TargetStatus into Target. 
This commit simplifies the TargetHealth type and moves the target
status into the target itself. This also removes a race where error
and last scrape time could have been out of sync.
 2016-03-01 14:33:21 +01:00
Fabian Reinartz 2060a0a15b Turn target group members into plain lists. 
As the scrape pool deduplicates targets now, it is no longer necessary
to store a hash map for members of each group.

Fabian Reinartz 0d7105abee Remove scrape config from Target. 
This commit removes the scrapeConfig entirely from Target.
All identity defining parameters are thus immutable now and the mutex
can be removed..

Target identity is now correctly defined by the labels and the full URL.
This in particular includes URL parameters that are not specified in the
label set.

Fingerprint is also removed from hash to remove an unnecessary tight coupling
to the common/model package.

Fabian Reinartz 75681b691a Extract HTTP client from Target. 
The HTTP client is the same across all targets with the same
scrape configuration. Thus, this commit moves it into the scrape
pool.

Fabian Reinartz 76a8c6160d Deduplicate targets in scrape pool. 
With this commit the scrape pool deduplicates incoming
targets before scraping them. This way multiple target providers
can produce the same target but it will be scraped only once.

Fabian Reinartz 84f74b9a84 Apply new scrape config on reload. 
This commit updates a target set's scrape configuration
on reload. This will cause all running scrape loops to be
stopped and started again with new parameters.
