OhmGraphite/CHANGELOG.md

0.7.0 - 2018-10-17

This is strictly a breaking change for TimescaleDB users (nothing else has changed). Previously OhmGraphite would create a schema and initialize the Timescale table. While convenient, creating tables, indices, etc automatically is not desirable for an application that could be installed on many client machines. In production, one may want to create indices on other columns, omit an index on the host column, or create custom constraints. OhmGraphite shouldn't dictate everything. In fact, OhmGraphite should be able to function with a minimal amount of permissions. That is why with the 0.7 release, automatic creation of tables, etc is opt-in via the new timescale_setup option.

Recommendation: create a user that can only insert into the ohm_stats table

CREATE USER ohm WITH PASSWORD 'xxx';
GRANT INSERT ON ohm_stats TO ohm;

Then initialize the ohm_stats appropriately.

If one desires OhmGraphite to automatically setup the table structure then update the configuration to include timescale_setup

  <add key="timescale_setup" value="true" />

A side benefit of this update is that OhmGraphite can now insert into traditional PostgreSQL databases.

0.6.0 - 2018-10-07

The big news for this release is TimescaleDB support, so OhmGraphite can now writes to a PostgreSQL database!

One can configure OhmGraphite to send to Timescale with the following (configuration values will differ depending on your environment):

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <appSettings>
    <add key="type" value="timescale" />
    <add key="timescale_connection" value="Host=vm-ubuntu;Username=postgres;Password=123456;Database=postgres" />
  </appSettings>
</configuration>

OhmGraphite will create the following schema, so make sure the user connecting has appropriate permissions

CREATE TABLE IF NOT EXISTS ohm_stats (
   time TIMESTAMPTZ NOT NULL,
   host TEXT,
   hardware TEXT,
   hardware_type TEXT,
   identifier TEXT,
   sensor TEXT,
   sensor_type TEXT,
   sensor_index INT,
   value REAL
);

SELECT create_hypertable('ohm_stats', 'time', if_not_exists => TRUE);
CREATE INDEX IF NOT EXISTS idx_ohm_host ON ohm_stats (host);
CREATE INDEX IF NOT EXISTS idx_ohm_identifier ON ohm_stats (identifier);

Currenlty the schema and the columns are not configurable.

All patch notes:

• Add TimescaleDB support
• Update inner dependencies:
  • Update Topshelf from 4.0.4 to 4.1.0
  • Update pometheus-net from 2.1.0 to 2.1.3
• Switch packing executable from ILRepack to Costura, as ILRepack is unable to pack in Npgsql without type exceptions at runtime.

0.5.0 - 2018-07-26

• Add Prometheus support
  • OhmGraphite now requires .NET v4.6.1 (up from .NET v4.6). Most users should be unaffected by this change.
• More metrics! OhmGraphite now takes advantage of metrics that the underlying hardware library detects at runtime.

0.4.0 - 2018-07-15

• Update LibreHardwareMonitor to 4652be0
  • Support for Ryzen 2000 series processors
• As long as OhmGraphite can send to a given graphite endpoint, keep a persistent tcp connection alive. Previous behavior would open a connection every interval seconds. This technique should work for 99% of use cases, but when there are a limited number of ports open on the client load one can receive the error "Only one usage of each socket address (protocol/network address/port) is normally permitted". The new behavior will keep the same connection open until there is a failure, which will then trigger a reconnect.
• Update internal dependencies
  • NLog (4.4.12) -> (4.5.6)
  • TopShelf (4.0.3) -> (4.0.4)

0.3.0 - 2018-05-14

• Update LibreHardwareMonitor to 3460ec
  • Support for NCT6792D (X99)
• Add opt-in to Graphite tag support
• Add InfluxDB support

This release is backwards compatible. For those interested in Graphite tags -- they are not backwards compatible! While tagged metrics will have the same name as pre-tagged OhmGraphite metrics, Graphite will treat them separately. So one can either merge these metrics or start over.

0.2.1 - 2018-05-03

Bugfix for users where their computer culture doesn't use a period . as the decimal separator resulting in warnings and no data being stored.

0.2.0 - 2018-04-02

Huge shout out to @jonasbleyl who discovered a whole swath of hardware metrics that can be reported!

• Report sub-hardware sensors. For those missing motherboard temperatures, fan controllers, and voltage metrics -- those should now be reported.
• Change logging of sensors without a value from warning to debug as fan controllers often don't have a value and we want to prevent log spam.

0.1.3 - 2018-03-07

• Increase logging done under DEBUG to aid diagnostics
• Ease upgrades by packing everything into OhmGraphite.exe. No need for the .dll files anymore. Upgrading now consists solely of replacing the executable.

0.1.2 - 2018-02-06

• Update LibreHardwareMonitor to 22bd00c
  • Z270 PC MATE support
  • Add support for Coffee Lake
  • Add support for Fintek F71878AD

0.1.1 - 2017-12-10

• Update LibreHardwareMonitor to 60e16046
  • Adds support for PRIME X370-PRO mobo
  • Additional metrics for Ryzen 7, Threadripper, and EPYC CPUs

0.1.0 - 2017-11-01

• Initial release
