Hi all,

I am currently investigating an issue for a server.
I notice alot of load early in the morning. However there is no clear pointer to what is the cause of this.

So I configured sar and am looking at the report.

At a certain time I found that one counter is significantly higher than when the load issue is not there.

00:00:01 CPU i000/s i001/s i006/s i007/s i008/s i009/s i012/s i015/s i051/s i059/s i067/s i075/s

The 4th last column seems to be significantly changing.
However I can't seem to find what this i051/s exactly is.
It is probably an interrupt code. However I am not clear what this interrupt stands for.

Could someone explain this counter to me or give a resource with explanation for all counters?

Thanks in advance!

Hi there,

Did you use the "sar" command to see this output? If so, what was the exact command you used?

I used the report file, didn't change any defaults.

/var/log/sa/sarxx or something I believe
