- rename some confusing names
- get mondemand_statdb:config() to print out parts of md_config table
- make sure gcounters are read from the appropriate table
- initialize gcounter rate to 0
- improve code coverage on a couple modules
* Tue Jun 04 2019 David Hull <[email protected]> 6.12.0
- Add gcounter type, a counter which emits values like a gauge.
- Add unknown type in statsmsg to match other libraries.
* Thu Feb 07 2019 Anthony Molinaro (djnym) 6.11.0
- update lwes library
- added a more robust mondemand.conf file parser
* Fri Dec 14 2018 Anthony Molinaro (djnym) 6.10.1
- use rebar3 in Makefile
- fix for when statsmsg contexts are mismatched, the library will no longer
crash
* Fri Jun 08 2018 Yoshihiro Tanaka (yoshi) 6.10.0
- Add literal memory usage stat
* Tue May 15 2018 Anthony Molinaro (djnym) 6.9.4
- have version in .app.src come from ChangeLog
* Mon May 14 2018 Anthony Molinaro (djnym) 6.9.3
- Switch ChangeLog format to semi-standard RPM format
- Fallback to a default config if the config file is not found
* Sat Apr 28 2018 Anthony Molinaro (djnym) 6.9.2
- minor fixes to compile without warnings under erlang 20
* Fri Oc 20 2017 Anthony Molinaro (djnym) 6.9.1
- forgot to bump the version in the .app.src
* Fri Oct 20 2017 Anthony Molinaro (djnym) 6.9.0
- don't print out info about flushing, instead just keep a metric.
- better unit test coverage
* Thu Apr 20 2017 Anthony Molinaro (djnym) 6.8.1
- avoid webmachine dependency
* Tue Mar 21 2017 Anthony Molinaro (djnym) 6.8.0
- add user state to the mondemand_statdb:map function so that you can do
the equivalent of mapfold there.
- alter flushing to use an initial state function
- added a convience function for adding contexts to events which support
them to mondemand_event.
* Mon Mar 06 2017 Anthony Molinaro (djnym) 6.7.0
- generalize flush functionality so that the server can plug in a slightly
modified version.
- cleanup some config, all application config should be read only in
mondemand_config
* Fri Feb 03 2017 Anthony Molinaro (djnym) 6.6.1
- make sure that mondemand vmstats metrics are not emitted without a full
interval having gone by. This means a restart of a service can lead to
a gap in vmstats, but that's better than the spikes which can happen without
waiting (IMHO).
* Thu Feb 02 2017 Anthony Molinaro (djnym) 6.6.0
- add scheduler utilization to vmstats
* Thu Oct 06 2016 Anthony Molinaro (djnym) 6.5.0
- add a call to get vmstats out from the vmstats sampler
- add a call to get all event names
* Mon Sep 19 2016 Anthony Molinaro (djnym) 6.4.1
- don't crash if http trace endpoint is not set
* Mon Sep 19 2016 Vikram Kadi (vikramkadi) 6.4.0
- now able to post traces over 65kb
- updated the version of lwes dependency
* Tue Aug 02 2016 Anthony Molinaro (djnym) 6.3.0
- fix median calculation where there is only one sample (since this is
ill defined, it will be set to zero)
- add fetch_sample_set/4 to allow fetching a sample set from a previous
minute
* Fri Jun 10 2016 Tim Whalen (whalen) 6.2.1
- moved max_metrics constant to mondemand_config so we can tweak at runtime
* Thu Jun 09 2016 Anthony Molinaro (djnym) 6.2.0
- added a function to convert from millis since epoch to erlang:now/0
format
* Wed Jun 01 2016 Tim Whalen (whalen) 6.1.0
- when sending stats emit multiple lwes events when num_metrics is large
* Thu May 12 2016 Anthony Molinaro (djnym) 6.0.0
- significantly improved performance when deserializing stats events
- improved coverage of mondemand_statsmsg as well as mondemand_event
- removed some unused fields from currently unused records, but since they
were in the public header
* Fri Feb 26 2016 Anthony Molinaro (djnym) 5.8.0
- significantly improved performance when deserializing performance events
- improved coverage of mondemand_perfmsg module
* Fri Feb 05 2016 Anthony Molinaro (djnym) 5.7.1
- minor dialyzer issue
* Fri Feb 05 2016 Anthony Molinaro (djnym) 5.7.0
- add annotation message support
- add accessors for performance messages
- fix for R15B port calls
* Fri Dec 04 2015 Anthony Molinaro (djnym) 5.6.0
- add port count and limit to vmstats
* Thu Dec 03 2015 Anthony Molinaro (djnym) 5.5.2
- syntax_tools needs to be in the required apps
* Mon Nov 23 2015 Anthony Molinaro (djnym) 5.5.1
- performance trace deserialization was broken
* Wed Oct 28 2015 Anthony Molinaro (djnym) 5.5.0
- vmstats can now be sent once a minute via mondemand when specified in the
application config file. A program id is required so a minimal config
might be something like
{ vmstats, [ { program_id, mondemand } ] }
in addition a context could be added via a context parameter with a
2-tuple list as an argument like
{ vmstats, [ { program_id, mondemand }, {context, [{foo,bar}]} ] }
* Tue Oct 27 2015 Anthony Molinaro (djnym) 5.4.2
- problem with context deserialization
* Fri Oct 09 2015 Anthony Molinaro (djnym) 5.4.1
- missing file in 5.4.0 release, as well as some additions to the
performance tracing event. Added contexts and a caller_label
* Thu Oct 08 2015 Anthony Molinaro (djnym) 5.4.0
- support performance messages as well as allowing sending of different
events to different channels.
* Fri Sep 18 2015 Anthony Molinaro (djnym) 5.3.1
- typo in restart code meant hot-restarts were failing with bad_ip_port
* Thu Aug 20 2015 Anthony Molinaro (djnym) 5.3.0
- allow more than one previous minute to be kept
* Mon Jul 13 2015 Anthony Molinaro (djnym) 5.2.0
- allow host sent in events to be overriden by an application env variable
and stored in a global (copied mochiglobal into the mondemand application).
- added collect_time which is the time that statsets were collected.
* Fri Jul 18 2014 Anthony Molinaro (djnym) 5.1.0
- added interface for gauges
- cap counters to max signed int64 as that's what lwes is doing
- allow for multiple configs in config file to emit to multiple servers
- added an mondemand_stats module which centralizes operations around stats
- added statset which collects samples in a reservoir and emits a
configurable amount of statistics each emit interval
* Fri Mar 14 2014 Anthony Molinaro (djnym) 5.0.0
- serialization of events now happens in calling process instead of while
sending
- make send_interval an application variable so you can change it from 60
seconds if you want
- mondemand:stats/0 now adds context when it's available
- trace messages now always use dicts internally to better match other
languages implementations
* Wed Feb 19 2014 Anthony Molinaro (djnym) 4.1.1
- updated dependency on version of lwes
* Fri Feb 14 2014 Anthony Molinaro (djnym) 4.1.0
- added a mondemand:stats/0 function to pretty-print stats
- updated dependency on version of lwes
* Mon Mar 28 2011 Anthony Molinaro (djnym) 4.0.0
- Trace messages now require a string message to be sent
* Mon Mar 21 2011 Anthony Molinaro (djnym) 3.0.0
- Update to deal with new lwes-erlang
- Added trace messages
- removed send_event call from public API, use trace messages instead
- sync version with other clients
* Fri Feb 04 2011 Anthony Molinaro (djnym) 1.3.0
- Default types to counters when increment has been used, otherwise allow it
to be set when sending stats
- fix bug with context num
* Wed Jan 26 2011 Anthony Molinaro (djnym) 1.2.0
- initial version, originally in another non-public repo, so versioning
reflects an upgrade from that version
