C++ (Cpp) proc_meminfo Examples

Example #1

File: client.c Project: ramiro-alba/lcmt

static int
_get_mem_usage (pctx_t ctx, double *fp)
{
    uint64_t kfree, ktot;

    if (proc_meminfo (ctx, &ktot, &kfree) < 0) {
        err ("error reading memory usage from proc");
        return -1;
    }
    *fp = ((double)(ktot - kfree) / (double)(ktot)) * 100.0;
    return 0;
}

Example #2

File: lmtmetric.c Project: LLNL/lmt

static int
_sysstat (pctx_t ctx, char *buf, int len)
{
    static uint64_t cpuusage = 0, cputot = 0;
    double cpupct, mempct;
    uint64_t ktot, kfree;
    int ret = -1;

    if (proc_stat2 (ctx, &cpuusage, &cputot, &cpupct) < 0)
        goto done;
    if (proc_meminfo (ctx, &ktot, &kfree) < 0)
        goto done;
    mempct = ((double)(ktot - kfree) / (double)(ktot)) * 100.0;
    snprintf (buf, len, "cpu_util: %.2f%% mem_util: %.2f%%", cpupct, mempct);
    ret = 0;
done:
    return ret;
