Metrics export enhancements
- Two shiny new surfacers: AWS CloudWatch and Datadog. (#141 & #583).
- You can now configure any surfacer to export metrics as gauge. You just need to add export_as_gauge to the surfacer config. (#604)
- Also, now you can add failure metric to any surfacer by adding add_failure_metric to the surfacer config. (#604)
- A common way to filter metrics. You now have fine-grained control of which metrics will be exported to which surfacer, e.g. you may want to send only critical probe metrics to an expensive monitoring system, while you may send all metrics to pub/sub or files. (#597)
Labeling
- Multiple substitutions: We now support multiple substitutions in labels, e.g. a label like @target.name@:@target.port@@target.relative_url@ will get appropriately substituted. (#582)
Targets Discovery
- RDS provider for file based targets. To allow sharing a large set of targets across multiple probes.
- Implement caching in RDS protocol. No need to re-process (on RDS server or client) targets that haven't changed. (#646)
[Above two changes allowed cloudprober to work with 1M targets in a single targets file. (#634)] - Add "node" and "pod" labels for K8s endpoints resources. (#612)
Bug Fixes
- External probe: Generate metrics even if requests timeout. (#653)
- External probe: Add additional labels to payload based metrics as well. (#654)
- HTTP Probe: Fix parallelism when running multiple requests per probe. (#647)
