    }
    long fd = nodeStats.getProcess().getOpenFileDescriptors();
    if (fd > 0) {
        // fd can be -1 if not supported on platform
        totalOpenFileDescriptors += fd;
    }
    // we still do min max calc on -1, so we'll have an indication of it not being supported on one of the nodes.
    minOpenFileDescriptors = Math.min(minOpenFileDescriptors, fd);
    maxOpenFileDescriptors = Math.max(maxOpenFileDescriptors, fd);
