v2.0 - Carbonator (beta2)

This release contains a hotfix for broken functionality when sending metrics to influxdb and additional logging (mostly debug level).

---

v2.0 status

This v2.0 build is considered stable, although it has not had a great exposure in production yet. Please submit an Issue if you see something funky.

Breaking Changes

• <graphite> element removed
  • Introduced <output> element which allows switching between graphite and influxdb via name attribute
    • Due to complexity with how paths are handled in graphite vs. how metrics are submitted in influxdb, only one template format would be supported
    • Changed path attribute in <counters/add> to template (semantics)
    • The template differs between influxdb and graphite. Graphite templates work just like in v1, however, v2 templates work as a prefix in their line protocol.
    • (e.g. <add template="disk-space,host=%HOST%,env=prod,disk=%COUNTER_INSTANCE%" ...> results in disk-space,host=MY-PC,env =prod,disk =C: C:=1132578 1473354688679524608 written to influxdb)
• Removed legacy configuration options
• Default log output is log4net (carbonator.log file in program's directory)
• Increased metric buffers
• Removed support for lower-case host name (%host% variable)

New Stuff

v2 introduces support for sending metrics to influxdb via HTTP POST. It is configured via <output> entry:
<add name="myinfluxdb" type="influxdb" postingUrl="http://localhost:8086/write?db=mydb" />

As described above, the template= attribute becomes a prefix format for influxdb metric line.
Carbonator will then use counter's instance name (e.g. "C:" in case of a Logical Disk), or "value" if instance name is empty and supply that value.

Example data transmitted for performance counters:

• Category=LogicalDisk Counter=% Free Space Instance=.+ (regex)
  • Configuration: <add template="disk-space,host=%HOST%,env=prod,disk=%COUNTER_INSTANCE%" category="LogicalDisk" counter="% Free Space" instance=".+" />
  • On-the-wire disk-space,host=MY-PC,env=prod,disk=C: C:=222123123 1473354688679524608
• Category=Memory Counter=Available Bytes Instance=[empty]
  • Configuration: <add template="memory_avail,host=%HOST%,env=prod" category="Memory" counter="Available Bytes" instance="" />
  • On-the-wire: memory_avail,host=MY-PC,env=prod value=1123123123 1473354688679524608

v1.6

• MetricPathBuilder class to build a metric path instead of CarbonatorInstance (testability)
• install-service.cmd encoded in UTF-8 without BOM (#11)
• Fix documentation (#12)
• Add support for custom metric path prefix (@omerlh, #18)

v1.5 - Carbonator

• Added ability to use ALL system environment variables in configurable metric paths (PR #4)
• Lowercase %host% in metric path (PR #8)
• Added %DOMAIN path variable which replaces with computer's A/D domain or machine name (if not joined to a domain) (Iss #6)
• CounterWatcher class that handles initializing/reporting on counters (decouple from CarbonatorInstance) - e9c7250
• Use either system Event Log or log4net for logging
• Deprecated logLevel configuration setting
• Ability to load instance performance counters based on a regular expression (e.g. a wildcard) (Iss #5)
• Removed collector interval auto-adjustment based on feedback in #3

v1.4

Changes in this version:

• Fix metric value formatting on certain systems (151606b, Iss. #2 )

v1.3

Changes in Release:

• Bug fixes: c694757, 323d59a, f2fd81b
• Configuration feature: 5a5fe6b (PR #1)
