Request enhancement for "warp --analyze" to use common output format for single and multi op results

[russfellows]

Request for Enhancement:

Warp’s resulting text output of the “—analyze” command is inconsistent. The inconsistency occurs when processing either single operation .zst files, or multi operation files. Also, for single operation result output, you provide additional information such as throughput, and object operations per second. These are NOT provided with multi operation result outputs. One simple remedy would be to utilize the exact same output format, ideally including the throughput for both. Note, there are several places where these differences occur, making processing of the results extremely difficult. Examples included below:

Difference #1:
After the “Operations loaded… Done!” line, the next line is different,
For single op types, there is a blank line, followed by a line of dashes “- - - - “
For a multi op type, there is no blank line, and no line of dashes, instead a line stating “Mixed Operations.”

Difference #2:
For a single op type file, there is additional information provided, giving throughput, and operations per second, see following example:
------ Example line ONLY included in single operation result files ------
Throughput:

• Average: 119.10 MiB/s, 2330.45 obj/s
  ------- End example ------

Again, it is important to note that this data is NOT provided in a mulit-op file.

Re 1)

Output is meant to be easily readable and not adhere to a specific formula.

Dashes in mixed just looks horrible:

warp analyze warp-mixed-2022-12-13[194820]-kPNY.csv.zst
1526625 operations loaded... Done!
Mixed operations.
----------------------------------------
Operation: DELETE, 10%, Concurrency: 24, Ran 14m59s.
 * Throughput: 169.63 obj/s

----------------------------------------
Operation: GET, 60%, Concurrency: 24, Ran 14m59s.
 * Throughput: 242.65 MiB/s, 1017.77 obj/s

----------------------------------------
Operation: PUT, 15%, Concurrency: 24, Ran 14m59s.
 * Throughput: 60.67 MiB/s, 254.45 obj/s

----------------------------------------
Operation: STAT, 15%, Concurrency: 24, Ran 14m59s.
 * Throughput: 254.44 obj/s

Cluster Total: 303.32 MiB/s, 1696.27 obj/s over 15m0s.

However, having it with details makes much more sense:

warp analyze -analyze.v warp-mixed-2022-12-13[194820]-kPNY.csv.zst

I will add that.

Re 2)

I am not sure I understand. The cluster total average is included at the end: Cluster Total: 303.32 MiB/s, 1696.27 obj/s over 15m0s
