Configuring the Sawmills Drop Metric Datapoints Processor

​

Configuration Components

​

1. Name

• Description: Identifier for your processor. Use a unique and descriptive name to differentiate between multiple processors.

​

2. Metric Names

• Description: List of metric names to target for dropping. Supports wildcard patterns.
• Examples:
  • http.server.request.duration - matches exact metric name
  • http.server.* - matches all metrics starting with http.server.
  • *.request.* - matches any metric containing .request.
• Functionality: All datapoints from metrics matching these patterns will be dropped unless narrowed by datapoint filters.

​

3. Datapoint Filters (Optional)

• Description: Conditions to narrow which datapoints are dropped. Without filters, all datapoints for the selected metrics are dropped.
• Logic Options:
  • Match all (AND): All conditions must be met for the datapoint to be dropped.
  • Match any (OR): At least one condition must be met for the datapoint to be dropped.

1. Choose the attribute key:
   • Select from available metric attributes/labels
2. Select a comparison operator:
   • Equals / Not Equals
   • Contains / Not Contains
   • Regex / Not Regex
3. Provide a value:
   • Enter the value to match against

​

Use Cases

• Cost Optimization: Drop high-cardinality metrics that provide limited value.
• Noise Reduction: Remove metrics from test or development environments.
• Selective Filtering: Keep only datapoints with specific label values by dropping everything else.
• Cardinality Control: Drop datapoints with specific high-cardinality label values.

​

Implementation Notes

• Metric name patterns support wildcards (*) for flexible matching.
• When no datapoint filters are specified, all datapoints for matching metrics are dropped.
• Combine metric name patterns with datapoint filters for precise control over which datapoints to remove.
