Description

As part of the Unified helm chart, this is the new chart for APM

• Changes from logzio-telemetry
  • drop support for daemonset mode. In logzio-telemetry it's required for metrics scraping per node which is not needed for traces
  • support enabling autoscaling for SPM via VPA
  • Secret values are read from .Values.global.<secretParam> section. This change provides two key benefits:
    • Enables the definition of tokens in the parent chart without duplication
    • Preserves the ability of each sub chart to control the values of its secrets
  • OTEL configuration changes:
    • Merge the config of latency and calls which renames span.name >> operation
    • Add _seconds prefix to Service Graph metrics (which was dropped in v109) following product request to keep the naming of metrics as it was
    • Add connector.spanmetrics.legacyMetricNames feature gate to keep old names of SPM metrics (which were changed to match the Service Graph metrics names in v109) following product request
  • Fine tune ClusterRole permissions and drop cluster-admin role permissions
  • Add support for easily changing the OTEL Collector logging level via a flag otelLogLevel
  • Listener address for SPM is automatically generated based on the region, for better user experience
  • Move all custom configurations to be generated in .tpl files (_helpers and _config)
  • Add resource limitations to the pods
• Aligned relevant tests
• Added readme
  • add custom tail sampling explanation section
  • moved changelog to it's own file CHANGELOG.md to keep the readme more clean
