cacher.py Traceback errors on 10.11.6 server 5.2

[elflames]

G'day eriking, I have tried to use you cacher.py script on my caching server as I too need a nice way to to show this is saving us bandwidth. Ever time i call cacher.py in terminal, i get the following output;

Traceback (most recent call last): File "/usr/local/bin/cacher.py", line 913, in main() File "/usr/local/bin/cacher.py", line 896, in main cacherdata = cacher(rawLog.readlines(), targetDate, friendlyNames) File "/usr/local/bin/cacher.py", line 167, in cacher frompeers_size = linesplit[17] IndexError: list index out of range

python is not my strong suit and I hope this error is a simple misconfig on my behalf. Any input from yourself would be greatly appreciated.

cheers Damien C

Ping @hunty1 - this is due to your code changes.

@elflames can you post your logs?

[erikng]

Also @elflames can you try https://github.com/erikng/Cacher/pull/37/commits?

[calum-github]

will need the logs to check.

10.11 doesnt have the metrics sql db so that commit above you'll need to change the flag to use the logs for getting metric information

o.add_option('--measurement',
 +                 help=('Optional: Measurement source, use either'
 +                       ' logs or metrics to specify either the Debug'
 +                       ' logs or metrics sqlite db as the source for'
 +                       ' calculating bandwith statistics'
 +                       ' Defaults to use metrics sqlite db'))```

[elflames]

will the last 500 lines of the current debug log be enough?

[erikng]

More than likely not. Some days cacher would look through 20,000+ lines. It just takes one bad line to cause this error.

On a side note I may need to stuff the main function into a try and print out the bad log line to help debugging.

Thanks, Erik Gomez

Just zip up the entire logs directory and send

logs attached in first message. please advise once you have them. cheers

Why are all your values in bytes?

This is why its tripping, its expecting a bandwidth type after the number

ie MB after 2.3

but yours are all in bytes already

ie

Served all 21102703 of 21102703 bytes

instead of what it should be like

Served all 21.1 MB of 21.1 MB

And this is why the line split is tripping up.

[elflames]

I am not suer why mine has defaulted to bytes. checking the server admin settings now.. using commit #37 code, I was able to get this to stdout;

Please confirm what OS version and what version of Server app you using. and what region are you from or using? US English?

[elflames]

macOS: 10.11.6 ServerApp: 5.2 Region: AUS happy to jump onto slack channel or free node channel.

[calum-github]

Are you sure its 5.2?

5.1.7 is the latest for 10.11.6

5.2 won't install/run on 10.11.6

I have a 10.11.6 caching server here with the latest version of server 5.1.7 and i am not seeing the output you are.

Perhaps you have manually or through some kind of automation have installed 5.2 on 10.11.6 somehow and thats causing you issues.

[calum-github]

My apologies, just built a 10.11.6 caching server here and 5.2 came down from the app store.

¯_(ツ)_/¯

Running a quick test not seeing the values in bytes here..... Must be something on your machine

[elflames]

I will rebuilding the server and see what I get.. Thank you for the quick replies and your continued development of this tool.

[elflames]

Prolly an id10t error.
