Is this type of trend monitoring is possible using nagios?. For this we need to collect data for some amount of time and store in data base and again fetch these values to check for the alert condition. If so how should be our plugins?. </FONT></DIV> <DIV><FONT face="Times New Roman" size=3>Can anyone help me out in this?.</FONT></DIV> <DIV><FONT face="Times New Roman" size=3></FONT> </DIV> <DIV><FONT face="Times New Roman" size=3>Regards,</FONT></DIV> <DIV><FONT face="Times New Roman" size=3>Jaya</FONT></DIV></FONT></DIV></BODY></HTML>
