[hobbit] CPU Utilization, Not Good

The agent may be using top to get an average across the entire sample period (300 seconds). When you run top interactively you are seeing a shorter sample. But I think there is some "smoothing" in top to begin with. To add some extra zest, the RRD tool also applies some normalization of its own to the data as it comes in.

To really answer your question, though, you should look at the source to see what parameters Hobbit is using for top, then you can compare the "raw" output with what is getting graphed.

Subject: [hobbit] CPU Utilization, Not Good



Hi,

 

I've asked this several times, but I really have not received

a good answer. Hobbit doesn't really seem to monitor cpu 

utilization correctly.

 

For example, I can look at the load, login to the box, and then

run top. Top shows that cpu utilization is at 100%, 0% idle

time.

However, the "trends" utilization graph shows 20% cpu

utilization.

Can someone tell me why?

 

Thanks....James
