v2.1.0

Changelog for 2.1.0

The following sections list the changes for 2.1.0.

Summary

• Chg #258: Switch to official logging library
• Chg #272: Add type to IP pricing and add metrics for primary IPs

Details

• Change #258: Switch to official logging library

  Since there have been a structured logger part of the Go standard library we
  thought it's time to replace the library with that. Be aware that log messages
  should change a little bit.

  #258

• Change #272: Add type to IP pricing and add metrics for primary IPs

  Since the client SDK has deprecated the previous handling for the pricing of IP
  addresses we had to update the metrics to include the type and location of the
  IPs. Besides that we have also added metrics for the pricing of the primary IP
  addresses.

  #272

v2.0.0

Changelog for 2.0.0

The following sections list the changes for 2.0.0.

Summary

• Fix #246: Fetch metrics for all servers
• Chg #240: Improve pricing error handling
• Chg #240: New traffic pricing metrics because of deprecation

Details

• Bugfix #246: Fetch metrics for all servers

  For previous versions we have used the wrong client function to gather the list
  of servers for the server metrics, this hvae been fixed by using a function that
  automatically fetches all servers by iterating of the pagination.

  #246

• Change #240: Improve pricing error handling

  So far we always existed the scraping if there have been any kind of error while
  parsing the metric values, from now on we are logging an error but continue to
  provide the remaining metrics to avoid loosing unrelated metrics.

  #240

• Change #240: New traffic pricing metrics because of deprecation

  The previous traffic pricing metrics have been deprecated and got to be replaced
  by new metrics as the new metrics have been split between service type like load
  balancers and server types.

  #248
  #240

v1.3.0

Changelog for 1.3.0

The following sections list the changes for 1.3.0.

Summary

• Chg #193: Read secrets form files
• Chg #193: Integrate standard web config
• Enh #193: Integrate option pprof profiling

Details

• Change #193: Read secrets form files

  We have added proper support to load secrets like the password from files or from
  base64-encoded strings. Just provide the flags or environment variables for token or private
  key with a DSN formatted string like file://path/to/file or base64://Zm9vYmFy.

  #193

• Change #193: Integrate standard web config

  We integrated the new web config from the Prometheus toolkit which provides a configuration
  for TLS support and also some basic builtin authentication. For the detailed configuration
  you can check out the documentation.

  #193

• Enhancement #193: Integrate option pprof profiling

  We have added an option to enable a pprof endpoint for proper profiling support with the help of
  tools like Parca. The endpoint /debug/pprof can now optionally be enabled to get the
  profiling details for catching potential memory leaks.

  #193

v1.2.3

Changelog for 1.2.3

The following sections list the changes for 1.2.3.

Summary

• Fix #175: Correctly read loadbalancer traffic

Details

• Bugfix #175: Correctly read loadbalancer traffic

  We used a wrong attribute to read the loadbalancer traffic which resulted in missing metrics
  for the realtime traffic in and out for all loadbalancers. With this fix you should be able to use
  the metrics.

  #175

v1.2.2

Changelog for 1.2.2

The following sections list the changes for 1.2.2.

Summary

• Fix #74: Another fix for go routines within server metrics
• Fix #72: Fix index out of range issue within server metrics

Details

• Bugfix #74: Another fix for go routines within server metrics

  We disabled the server metrics by default for now until the implementation is really stable to
  avoid any side effects. I have reintroduced routines, otherwise the scrapetime will be far too
  high. This time I used wait groups to get everything handled properly.

  #74

• Bugfix #72: Fix index out of range issue within server metrics

  The code has not checked if an index have been really available within the server metrics API
  response. With this fix it gets properly handled.

  #72

v1.2.1

Changelog for 1.2.1

The following sections list the changes for 1.2.1.

Summary

• Fix #70: Fix go routine errors within server metrics

Details

• Bugfix #70: Fix go routine errors within server metrics

  We fixed a go routines issue within the new server metrics. We just got rid of the routines to
  avoid any errors related to sending to closed channels.

  #70

v1.2.0

Changelog for 1.2.0

The following sections list the changes for 1.2.0.

Summary

• Chg #67: Add collector for server metrics
• Chg #53: Integrate standard web config

Details

• Change #67: Add collector for server metrics

  Hetzner Cloud collects basic metrics on the hypervisor-level for each server. We have added a
  new collector which scrapes the latest available metric point for each running server. It is
  enabled by default.

  #67

• Change #53: Integrate standard web config

  We integrated the new web config from the Prometheus toolkit which provides a configuration
  for TLS support and also some basic builtin authentication. For the detailed configuration
  you check out the documentation.

  #53

v1.1.0

Changelog for 1.1.0

The following sections list the changes for 1.1.0.

Summary

• Chg #25: Drop darwin/386 release builds
• Chg #39: Add collector for load balancers
• Chg #24: Refactor build tools and project structure
• Chg #21: Add collector for volumes

Details

• Change #25: Drop darwin/386 release builds

  We dropped the build of 386 builds on Darwin as this architecture is not supported by current Go
  versions anymore.

  #25

• Change #39: Add collector for load balancers

  We have added a new optional collector, which is enabled by default, to gather metrics about all
  loadbalancers part of the configured Hetzner Cloud project.

  #39

• Change #24: Refactor build tools and project structure

  To have a unified project structure and build tooling we have integrated the same structure we
  already got within our GitHub exporter.

  #24

• Change #21: Add collector for volumes

  We have added a new optional collector, which is disabled by default, to gather metrics about
  the volumes part of the configured Hetzner Cloud project.
