Overview
This filter type can be used to process OTLP (Open Telemetry) traces.
This filter type samples failed and high-latency traces with successful traces and a sampling probability.
This filter supports OTel traces.
Review Parameters
Review the following parameters that you can configure in the Edge Delta App:
| Visual Editor | YAML | Description |
| Not applicable | name |
Enter a descriptive label for this filter / processor. When you create a workflow, you will use this label to enter your filter into the workflow. This parameter is required. Review the following example: name: opentelemetry_trace_filter |
| Not applicable | type |
Enter buffered-otlp-trace-processor. This parameter is required. Review the following example: type: buffered-otlp-trace-processor |
| Not applicable | trace_deadline |
Enter a deadline to wait for the last event of a trace. When a deadline is reached, the filter will be applied to the events of the trace. 30s is the default value. This parameter is optional. Review the following example: trace_deadline: 1m |
| Not applicable | should_filter_traces |
Enter true or false to filter traces based on failures, high-latencies, and sampling rate. This parameter is optional. Review the following example: should_filter_traces: true |
| Not applicable | failure_path |
Enter the path where the failure information will be obtained from. The obtained value will be converted into a string. You can enter a name or attribute. This parameter is optional. Review the following example: failure_path: "attributes.result_code" |
| Not applicable | failure_value_pattern |
Enter a pattern to match against the obtain value from failure_path. This parameter is optional. Review the following example: failure_value_pattern: "(4|5)xx" |
| Not applicable | latency_threshold |
Enter a threshold value for latency. If a high-latency trace exceeds the entered value, then that trace will pass the filter. This parameter is optional. Review the following example: latency_threshold: 2500.0 |
| Not applicable | success_sample_rate |
Enter a floating number between 0 and 1. 0.0 is the default value. This parameter is optional. Review the following example: success_sample_rate: 0.1 |
