Question 1

goroutine-inspect vs pprof for goroutine analysis

Accepted Answer

goroutine-inspect offers interactive filtering and deduplication for static dumps, making it better for deep, manual investigation, while pprov provides live profiling and web-based visualization but less fine-grained control over large trace sets.

Question 2

How to filter goroutines by duration in goroutine-inspect

Accepted Answer

Use the search() function with a conditional like 'duration > 10' to show goroutines running longer than 10 minutes, as demonstrated in the README where it highlights long-running goroutines for leak detection.

Question 3

Can goroutine-inspect analyze live goroutines?

Accepted Answer

No, it only processes goroutine dump files saved from tools like pprof, so you need to generate dumps first before loading them into the interactive shell for analysis.

Question 4

How to save a modified goroutine dump in goroutine-inspect

Accepted Answer

After manipulating a dump variable, use the save() function, e.g., 'a.save("pprof-deduped.log")', to export the filtered or deduplicated results to a text file for sharing or further review.

Question 5

Does goroutine-inspect support JSON output?

Accepted Answer

No, the current version only saves to plain text files, so if you need structured data for automation, you'll have to parse the output manually or use other tools in conjunction.

Question 6

Is goroutine-inspect good for large production dumps?

Accepted Answer

Yes, its deduplication and filtering features help manage thousands of goroutines, but performance might slow with extremely large files, and it requires manual interaction rather than batch processing.
