Releases: grafana/carbon-relay-ng
more tuneables for destinations
these new settings were previously hardcoded (to the values that are now the defaults):
connbuf=<int> connection buffer (how many metrics can be queued, not written into network conn). default 30k
iobuf=<int> buffered io connection buffer in bytes. default: 2M
spoolbuf=<int> num of metrics to buffer across disk-write stalls. practically, tune this to number of metrics in a second. default: 10000
spoolmaxbytesperfile=<int> max filesize for spool files. default: 200MiB (200 * 1024 * 1024)
spoolsyncevery=<int> sync spool to disk every this many metrics. default: 10000
spoolsyncperiod=<int> sync spool to disk every this many milliseconds. default 1000
spoolsleep=<int> sleep this many microseconds(!) in between ingests from bulkdata/redo buffers into spool. default 500
unspoolsleep=<int> sleep this many microseconds(!) in between reads from the spool, when replaying spooled data. default 10
some fixes (requires config change)
- unrouteable messages should be debug not notice #198
- rewrite before aggregator; fix race condition, sometimes incorrect aggregations and occasional panics #199
- config parsing fix #175
- kafka-mdm: support multiple brokers. fix #195
- bugfix: make init section work again. fix #201
attention init section must be changed from:
init = ...
to:
[init]
cmds = ...
note : this was previously released as 0.8.9 but the breaking config change warrants a major version bump.
3 new aggregators, better input plugins and packaging; and better config method
inputs
better pickle input #174
better amqp input options #168, update amqp library 3e87664
kafka input logging fixes #188
config
more proper config format so you don't have to use init commands. #183
aggregations
add last, delta and stdev aggregator #191, #194
packaging
Add tmpfiles.d config for deb package #179
prevent erasing of configs #181
add root certs to docker container for better grafanaCloud experience #180
better docs and stuff
minor release
multi-line amqp
see #165
amqp input, min/max aggregators, and more
- fix metrics initialisation (#150)
- update to new metrics2.0 format (mtype instead of target_type)
- refactor docker build process (#158)
- amqp input (#160)
- allow grafanaNet route to make concurrent connections (#153) to Grafana hosted metrics
- add min/max aggregators (#161)
- add kafka-mdm route for metrictank (#161)
v0.8: Growing up a little
- build packages for ubuntu, debian, centos and automatically push to circleCI upon successfull builds (https://github.com/graphite-ng/carbon-relay-ng#installation)
- add pickle input (#140)
- publish dashboard on grafana.net
- fix build for go <1.6 (#118)
- allow overriding docker commandline (#124)
- validation: tuneable validation of metrics2.0 messages. switch default legacy validation to medium, strict was too strict for many. show validation level in UI. Add time-order validation on a per-key basis
- support rewriting of metrics
- document limitations
- grafana.net route updates and doc updates
- re-organize code into modules
- various small improvements
- remove seamless restart stuff. not sure anymore if it still worked, especially now that we have two listeners. we didn't maintain it well, and no-one seems to care
known issues:
there's some open tickets on github for various smaller issues, but one thing that has been impacting people a lot for a long time now is memory usage growing indefinitely when instrumentation is not configured (because it keeps accumulating internal metrics).
The solution is to configure graphite_addr
to an address it can send metrics to (e.g. its own input address)
see ticket 50 for more info
200 stars
changes:
- regex / substring / prefix support for blacklist
- support more management functionality in admin UI + show dest online status
- properly set default endpoint settings
- configurable maxprocs setting
- consistent hashing (functions same as in official carbon but without replication >1)
- pidfile support
- include example init file & dockerfile
- switch to govendor for native vendoring && update some dependencies
- UDP listener
- pull in js libraries over https
- make validation configurable
- update included dashboard for grafana3
- rate controls for profiling
- experimental new grafana.net hosted metrics route
- refactored imperatives (commands) parsing
- fix versioning when building packages
overhauled codebase, non-blocking operations, more solid
- lots of code refactoring. non-blocking operations
- new config format with imperative commands
- extensive internal stats & grafana dashboard
- a more extensive routing system (which can support round robin & hashing) (see #23)
- aggregators
- use party tool for vendoring dependencies
- metric validator with json endpoint for inspection
- performance fixes
probably more. (was blacklists new?)
note: the admin interfaces need more work.
extended version with more features
extended version with config file, http and telnet interfaces, statsd for internal instrumentation, disk spooling support, but still blocking sends
