load average: 1.89, 1.69, 1.72

its shows

last 1 min, 5 min and 15 min  average how much load your server had

you need to see how many process you got



like for 8 core processor
i would expect something like

load average: 6.89, 7.69, 6.72

which means, its has used 6 core from last 1, 5 and 15 min interval

as long as it does not more then your core , i wold not worry ..
