graphic interface for smartahci

<< < (2/6) > >>

Doug Bissett:
I will comment here, that I do not trust anything that, so called, smart monitoring tells me. I have (had) one disk that never showed any problem, but just plain wouldn't work because of errors. I have another disk, that has been telling me that total failure has already happened, but it continues to work, with no problems, after 10 years (I do need to turn off the BIOS checking, or it refuses to use the disk). I had another one, that told me that all was well, and it became unusable 3 days later.

Use it if you want to, but be very wary of what it tells you. Better to spend your time doing backups.

ivan:
I agree with you Doug especially about backups.  If used properly the SMART information can be useful (in the graphic the attributes marked with * are the ones to watch.  I have had a couple of disks that worked but it took them up to 5 minutes to spin up so they got pensioned off before the stopped spinning at all.  Relocated sector count is another one to watch because disks only have a limited number of sectors to relocate and when they are used up problems start.

SMART data isn't for general use, you have to know what you are reading and how it interacts with the disk electronics firmware.

Which leaves me wondering hoe to get a graphics display like the attachment.

Any Ideas?

Might be as simple as setting the correct terminal (doubtful as I don't see any ansi) or more likely, need compiling with ansi support. I don't have an ahci adapter so can't test but assuming it shares the same source as smartmon, it should be able to output the correct ansi.

It looks like the Worst column is used for the indicator.  When it's 100, it has red, yellow, yellow, then full greens.  When it was 99, it drops down one, same with 92.  When it was 82 or 75, it had fewer greens.

It seems to just be a projection of that value relative to what it should be.  Some values seem to be up to 100.  Others 200.  Others 255.

Something like (off the top of my head, untested):

--- Code: ---char ansi_red[]     = "whatever the code is for ANSI red";
char ansi_yellow[]  = "whatever the code is for ANSI yellow";
char ansi_green[]   = "whatever the code is for ANSI green";
char ansi_normal[]  = "whatever the code is for ANSI normal";

// See http://ascii-table.com/ansi-escape-sequences.php
// Possibly the codes are ... don't know, haven't used them since DOS days in 90s:
// ansi_red    = "\033[1;31;40m";
// ansi_yellow = "\033[1;33;40m";
// ansi_green  = "\033[1;32;40m";
// ansi_normal = "\033[0;37;40m";

char* get_indicator(int value, int max_value, int& len)
{
    int   s, d;
    char* ind;

    // Make sure the parameters are in range
    max_value = max(max_value, 1);
    value = min(value, max_value);

    // Get the length we'll need
    len = (int)(10.0f * (float)value / (float)max_value);

    // Allocate the maximum length we'll need for the indicator
    ind = malloc(   ((len >= 1) ? sizeof(ansi_red)    : 0)
                  + ((len >= 2) ? sizeof(ansi_yellow) : 0)
                  + ((len >= 4) ? sizeof(ansi_green)  : 0)
                  + len
                  + sizeof(ansi_normal) + 1  );

    // Render it in ANSI
    for (s = 0, d = 0; s < len; ++s)
    {
        // Add any ANSI codes:
        if (s == 0)
        {
            // Add red
            memcpy(ind + d, ansi_red, sizeof(ansi_red) - 1);
            d += sizeof(ansi_red) - 1;

        } else if (s == 1) {
            // Add yellow
            memcpy(ind + d, ansi_yellow, sizeof(ansi_yellow) - 1);
            d += sizeof(ansi_yellow) - 1;

        } else if (s == 3) {
            // Add green
            memcpy(ind + d, ansi_green, sizeof(ansi_green) - 1);
            d += sizeof(ansi_green) - 1;
        }

        // Store the thick hyphen character
        ind[d++] = 22;
    }

    // Add the trailing restore to normal coloring
    memcpy(ind + d, ansi_normal, sizeof(ansi_normal) - 1);
    d += sizeof(ansi_normal) - 1;
    ind[d] = 0;

    // Return our result
    return ind;
    // Note:  len is updated to the number of thick hyphen characters to be displayed, not the string length
}

--- End code ---

If you are able to parse that data in raw text content, you could generate the display using something like ANSI escape codes and the ASCII 22 character.  Or paint it on the terminal using color attributes.  In either case, something like the above should work.

Make sure you free() the return value later.

Here's an actual program that displays some colorize results.  It doesn't handle the ID#... header line properly, but it does demonstrate the general idea.
