  • The median value is expressed with a horizontal, coloured line piece at the time the packets were send.
  • The # packets lost are expressed with the colour of the line piece.
  • The distribution of the Round-Trip-Times in the set of packets send are expressed with a vertical set of gray blocks, where the blackness of a block is an indication for the # packets in the sample bin, expressed by the height of the block. The gray blocks are of course only drawn when the distribution of Round-Trip-Times is observable from within the resolution of the ping command and / or the vertical RTT scale.

Por ahora no hay soporte a SATA If you ever tried to use smartctl to read info from your SATA drive, it will fail because libata doesn't yet support the needed ATA-passthrough ioctl() calls. Jeff Garzik, the developer of libata, says it will support it in the future. In the meantime you can apply a patch, and use libata-dev. The libata patchset can be acquired from http://www.kernel.org/pub/linux/kernel/people/jgarzik/libata/ , and after you install it, you can use smartctl to read SMART info from SATA device. However you must specify, on the command line, option "-d ata"
