Sampled stack traces of applications that identify hot-spots in application code. Executable symbols are required for human-readable function names to be displayed.
Column | Type | Pattern | Desc |
---|---|---|---|
time_ | TIME64NS | METRIC_COUNTER | Timestamp when the data record was collected. |
upid | UINT128 | GENERAL | An opaque numeric ID that globally identify a running process inside the cluster. |
stack_trace_id | INT64 | GENERAL | A unique identifier of the stack trace, for script-writing convenience. String representation is in the `stack_trace` column. |
stack_trace | STRING | GENERAL | A stack trace within the sampled process, in folded format. The call stack symbols are separated by semicolons. If symbols cannot be resolved, addresses are populated instead. |
count | INT64 | METRIC_GAUGE | Number of times the stack trace has been sampled. |
