I have an AIX (v5.1) server being monitored and recenty the hourly average % has  -2,506,511,387.454 displayed at various times, this causes the graphs to look wrong and hard to troubleshoot server loading issues.

 

example below

Date Time Minimum value in % Maximum value in % Hourly Average in %
Jul 11,2011 9:00 - 100  -2,506,511,387.454     

Any ideas ?

 

regards
