Checkpoint fingerprint mappings only upon shutdown
 2016-04-15 01:05:32 +02:00
beorn7 a90d645378 Checkpoint fingerprint mappings only upon shutdown 
Before, we checkpointed after every newly detected fingerprint
collision, which is not a problem as long as collisions are
rare. However, with a sufficient number of metrics or particular
nature of the data set, there might be a lot of collisions, all to be
detected upon the first set of scrapes, and then the checkpointing
after each detection will take a quite long time (it's O(n²),
essentially).

Since we are rebuilding the fingerprint mapping during crash recovery,
the previous, very conservative approach didn't even buy us
anything. We only ever read from the checkpoint file after a clean
shutdown, so the only time we need to write the checkpoint file is
during a clean shutdown.

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.

Implement relative complement set operator "unless"
 2016-04-04 21:36:17 +02:00
Tobias Schmidt 8cc86f25c0 Implement relative complement set operator "unless" 
The `unless` set operator can be used to return all vector elements from
the LHS which do not match the elements on the RHS. A use case is to
return all metrics for nodes which do not have a specific role:

    node_load1 unless on(instance) chef_role{role="app"}

beorn7 4b574e8a61 Switch chunk encoding to type 2 where it was hardcoded type 1 before 
The chunk encoding was hardcoded there because it mostly doesn't
matter what encoding is chosen in that test. Since type 1 is
battle-hardened enough, I'm switching to type 2 here so that we can
catch unexpected problems as a byproduct. My expectation is that the
chunk encoding doesn't matter anyway, as said, but then "unexpected
problems" contains the word "unexpected".
