I found that urls containing spaces are not handled correnctly by trac. Most likely its about the escaping in nginx.

Sample URL is provided below: ​http://www.smartmontools.org/timeline?from=2011-10-20T19%3A20%3A23Z&precision=second

Cant find any specification and attributes seems to be very non-standard. E.g. 174 and 175 according to my tests are read/write in Mb.

On Darwin (OSX) ATA_LOG_EXT command is not implemented, as well as on some other outdated ATA interfaces. However i found that device statistic is readable using smartlog 0x04 page.

This is sample output with my dirty hack for darwin:

Device Statistics (SMART Log 0x04)

  1  =====  =                =  == General Statistics (rev 2) ==

  1  0x010  4              413  Power-on Hours
  1  0x018  6       4466199876  Logical Sectors Written

  7  =====  =                =  == Solid State Device Statistics (rev 1) ==

                              |_ ~ normalized value

Correct logic on -ldevstat should be:

1. Check if gplog is supported
2. If not - check if SMART log page 0x04 available and use it as fallback

Also os_darwin.cpp needs to be converted to the new interface (#103) to support multi-sector requests.
