* Procstat: don't cache PIDs
Changed the procstat input plugin to not cache PIDs. Solves #1636.
The logic of creating a process by pid was moved from `procstat.go` to
`spec_processor.go`.
* Procstat: go fmt
* procstat: modify changelog for #2206
* ceph: maps are already refs, no need to use a pointer
* ceph: pgmap_states are represented in a single metric "count", differenciated by tag
* Update CHANGELOG
* Add in support for looking for substring in response
* Add note to CHANGELOG.md
* Switch from substring match to regex match
* Requested code changes
* Make requested changes and refactor to avoid nested if-else.
* Convert tabs to space and compile regex once
* Make Logparser Plugin Check For New Files
Check in the Gather metric to see if any new files matching the glob
have appeared. If so, start tailing them from the beginning.
* changelog update for #2141
If we write a batch of points and get a "field type conflict" error
message in return, we should drop the entire batch of points because
this indicates that one or more points have a type that doesnt match the
database.
These errors will never go away on their own, and InfluxDB will
successfully write the points that dont have a conflict.
closes#2245
doing this unblocks incoming metrics while waiting for a flush to take
place.
we have to create a semaphore so that we can
'skip' flushes that try to run while a flush is already running.
closes#2262
this basically reverts #887
at some point we might want to do some special handling of reloading
plugins and keeping their state intact, but that will need to be done at
a higher level, and in a way that is thread-safe for multiple input
plugins of the same type.
Unfortunately this is a rather large feature that will not have a quick
fix available for it.
