* Make updating metricsConfig and updating metricsExporter atomic
This requires doing anything with a kubeclient before obtaining the
metricsMux lock.
* Address PR
* Revert "Add support for client TLS to pkg/metrics (#1045)"
This reverts commit 945b556708.
* Roll forward "Add support for client TLS to pkg/metrics (#1045)"
Adds support for client TLS certs for opencensus export
* Switch sharedmain to only pass a getter rather than an all-namespace lister.
* Add a TODO about using a cached copy if this generates undue load
* Update deps per build failure.
* Refactor per @anniefu suggestion
* Document the plan for metrics
* Update with issue links
* Update with other @mattmoor comments.
* Address feedback from @anniefu
* Update export address since `localhost` won't work for a DaemonSet.
* Add an explicit action item to migrate Prometheus
* Fix possible (ambiguous) link vs checkbox.
* Fix typo in metrics/README.md
* Add support for client TLS to pkg/metrics
* Address comments from @vagababov and @anniefu
* Finish removing Resource code
* Update name to be shorter and not require a double migration.
* Add tests for opencensus exporting with TLS
* Add RecordN method to permit recording of N measurements simultaneously.
In serving we have many places where we try to record several metrics at the same time.
Besides very repetetive code, this also brings inefficiences, since metrics code has to do _some_ work
for every call, which is completely avoidable.
This way we can record N measurements with one hit.
* tests and nits
* review items per discussion with Evan:
- remove ros
- make measurements ...
* review
* Add support for OpenCensus Agent as a destination for Knative metrics.
* Update with comments from @mattmoor and @anniefu
* Remember to register exporter.
Fix tests.
* Fix naming per discussion with @anniefu
the observability config is used in other packages including
the sample controller. This commit pulls observability config
into knative.dev/pkg similar to logging config for better reusability.
* Restrict Stackdriver Secret to controlled name & namespace
* Address PR comments
* Lock when reading secret name & namespace
* Export StackdriverClientConfig struct so consumers don't have to
redefine it
* Ensure metrics pkg consumers call SetStackdriverSecretLocation to set
Secret name and namespace
* Export StackdriverClientConfig consts & helper function
* Add TODO for secret watcher
* Add field to metrics config for configuring Stackdriver exporter client
options
* Fix test setting global state and interfering with other tests
* Use correct GCP metadata values & cleanup
* Some code cleanup
* Remove as much test-specific function stubbing as possible
* Remove more stubbed out test code
* Make more descriptive error when getting secret
* Use former locking pattern to avoid deadlock
There is a cyclical dependency between the metrics pkg and client-go
kubeclient where the kubeclient will attempt to read the metricsConfig
to record metrics about kubeclient requests. This prevents using a kubeclient within the metricsMux lock.
* Remove race condition between reading updates to config-observability
and updating stackdriver exporter
* Simply isNewExporterRequired if statement
* Remove unused thread-safe versions of functions
* Use a reader-writer lock & add function comment
* Make internal unlocked function names consistent
* renaming source_name and source_resource_group to name and resource_group,
as they will be used in other resources
* updating
* updates based on code review
* update
* fix
* source stats reporter... should be used by well-behaved sources
* public fields
* moving serialization/deserialization of metrics and logging maps to pkg
* nits
* adding UT
* same order
* updates
* sock-puppet
* unregistration problem?
* removing base64 encoding
* removing TODO
* comments after review
* removing the other constants
* split and update
* bug fixed
* change the copyright year
* use fake metadata in tests
* exclude test coverage for gcp_metadata
* add record
* add tests
* revert 2019 and add a new var
* change documents
* address comment
* change line
* Use different reporting periods based on the metrics backend. Original implementation was setting this value to 1 min to accommodate the minimum allowed value for stackdriver, but that is a sub optimal behavior for Prometheus. The change also allows operator to override the default values.
* Fix the units of reconciler latency from nano seconds to milliseconds.
* Address PR comments.
* Add better logging for reconciliation.
* Remove unnecessary lock in the UT.
* Address PR comments.
* fix flaky test
* relax the requirement for stackdriver project id
* improve log
* add comment for stackdriverProjectIDKey not provided case
* minor format
* simplify the map access
* update dep golang.org/x/net
* Add stackdriver exporter support in pkg
* fix race and tests
* Use thread safe newMetricsExporter in tests
* address cr comments
* minor fix
* checkpoint
* Address cr comments
* add test for UpdateExporterFromConfigMap
* Move lock position
* add a test case for stackdriver error check
* minor change
* removing one test case since it seems app default creds exists for presubmit tests
* replace promSrvChan with promSrv as cr suggsted
* use a local var server for ListenAndServe
* add getter and setter for shared variables
* add func isMetricsConfigChanged and test
* address cr comments
* Update opencensus-go-exporter-stackdriver to v0.7.0
* Revert "Update opencensus-go-exporter-stackdriver to v0.7.0"
This reverts commit 9825f641f8.
