v0.13.4

2 weeks ago

New Features / Enhancements

  • Latency Breakdown for HTTP Probes Provide a way to report latency breakdown for HTTP probes (#699).

  • gRPC Probe Enhancements

    • Wait for successful connection before sending the request (#726, #729). By default gRPC's DialContext returns immediately even for the non-retryable errors. This mechanism doesn't work very well for probing -- there is no error message to show problems with the connection and connection is in the TRANSIENT_FAILURE state. We now use grpcurl's BlockingDial which takes care of these issues.
    • Use client TLS by default for encryption. (#727)
    • Capture request error messages better. (#731)

  • Streaming Metrics for external probes Parse and export external probes' metrics as soon as they are available. (#708, #712, #713, #715, #716, #722) This feature enables use cases where external probe runs less frequently (say 1 every 60s) but runs many tasks (for performance measurement, e.g.) and export results many times (say every 5s) within that interval. See discussion in #691 and #689 for more background.

  • Bulk writes in postgres surfacer Batch postgres surfacer writes to improve peformance (#717).

  • Allow DNS Overrides Allow overriding DNS server (#707).

Other Changes

  • Add a command line flag to control prometheus metrics prefix: --prometheus_metrics_prefix (#732).
  • Fix ostgres surfacer metric filter (#711).
  • [prober.saveconfig] Write probe configs to disk in order (#721).
  • [tls] Reload server certificates as well (#719).
  • [build.tools] Fix where python proto stub is copied to (#700).
  • [build] Update net dependency for sec alert (#728).
  • [build] Update protobuf package to fix security alert (#714).

v0.13.3

1 month ago

What's Changed

  • Probe scheduling capability:
    • You can now run probes only on the weekdays, only business hours, or turn them off during certain time periods. (#652, #662, #683)
  • External probe server:
  • DNS Probe Improvements:
    • Allow running multiple probes in parallel. (#670)
    • Add support for TCP DNS probes. (#681)
  • Dynamic config: Provide a mechanism to save config to disk on dynamic change. If you program probes dynamically using gRPC interface for example, you can configure cloudprober such that it will reload the config on restart (see https://github.com/cloudprober/cloudprober/issues/645 for more background). (#671)
  • Jsonnet configs support. You can now write Cloudprober configs in textpb (protobuf text), YAML, JSON, and Jsonnet (#687)
  • [surfacers.otel] Additional resource attribute support. (#664)
  • [tls] Fix client cert handling when cert reloading is enabled. (#697)
  • [logs] Redirect container logs to journald. (#682)
  • [website.homepage] Add a diagram to Cloudprober homepage. (#674)
  • [servers.http] Fix /healthcheck when lameduck lister is not initialized. (#684)

v0.13.2

4 months ago

What's Changed

  • [config] Make cloudprober configs composable. You can now include other configs within a cloudprober config. This will make multi-team config management easier (yay!! 🎉) . #643 (Note this doesn't work for YAML configs yet)
    • Cloudprober helm chart also supports specifying additional configs now.
  • [surfacers] Add OpenTelemetry surfacer. OpenTelemetry is becoming very popular and almost all metrics systems support it. Adding this surfacer increases Cloudprober's integration capabilities multifold. There may still be some rough edges but give it try. #642
  • [surfacers] "failure" metric for all. Now all surfacers, except FILE and PUBSUB, export "failure" metric by default. You can still disable it if you want. #648
  • [surfacers] Filtering metrics by name works for all surfacers now except FILE and PUBSUB. #648
  • [probes.ping] Take a small pause between pushing packets to avoid overwhelming the network buffers by @jumpojoy in https://github.com/cloudprober/cloudprober/pull/634
  • [docs] Documentation enhancements. #627 #650
  • [build] Fix Dockerfile.dev by @jumpojoy in https://github.com/cloudprober/cloudprober/pull/632

Breaking Change

  • [targets] Rename targets.endpoints to targets.endpoint (#646). With this change targets { endpoints {} } config fields will result an error. Sorry for the breaking change, but since these fields were introduced only in the last release (v0.13.1), impact should be minimal.

Security Update

Alerting Enhancements

  • Opsgenie integration 🎉 #570
  • Add a generic HTTP notifier. This can be used for pretty much anything. #599

Other Changes (consistency, logs verbosity, documentation, etc)

  • [probes] Make DNS resolve errors behavior more consistent: #616, #619, #620
  • Provide a way to specify detailed targets configuration in the config directly. This will simplify configuration quite significantly. #606
  • [targets] Make targets optional for certain probes. #614
  • [probes] Return an error if interval is smaller than timeout. #560
  • Reduce logs verbosity: #555, #562, #563

  • [probes.grpc] Disable connect failures test for macos. #579
  • [examples] Fix myprober example and simplify it. #568
  • [build] Don't fail fast. Run as many tests as possible. #574
  • [build] Run certain actions only in the main repository. #621

Bug fixes

  • [probes.http] Fix HTTP request body handling and add a lot of tests. We were using a custom reader for HTTP request body to optimize some aspects of it, but some parts of the Go's HTTP implementation expect the request body to be a buffered reader. #408, #407, #409, #411
  • [oauth2] Fix a bug in HTTP token refresh, introduced by the above change. #422
  • [probes.http] Fix how we determine whether to change the TLS config servername. #420
  • [probes.udp] Fix additional labels handling for UDP probe. #421

Other changes

  • [alerting] Add support for email notifications. #403
  • [alerting] Fix config protobuf package name. #402
  • [build] Exclude "tip" from releases. #400

Alerting

It's official. Cloudprober is getting its own alerting functionality 🎉. This release marks the beginning of the alerting implementation. We'll add more ways to notify an alert, but you can already trigger a command on alert. User documentation coming soon, but in the meantime, you can take a look at the alerting config proto to get an idea.

PRs: #359, #361, #364, #365, #380, #384, #387

Enhancements
