Hi all, ever since I started building up our new nagios environment under nagios 3.0, I noticed that my logfile contains massive amounts of HOST UP alerts - even though the host was never down before. Actually I seem to have this log entry each time a host is checked, I guess they get checked for the predictive and cache host tests. But sadly it's getting a real pain, since the logfile is growing so big, that my firefox even crashes when I try to view it with the webinterface. My daily nagios.log has the massive amount of roundabout 110.000 entries each day - which is little bit too much for its 400 hosts / 1600 services imho. Nearly the same checks (actually a few less, but whatever) produce roundabout 10.000 lines of log on our nagios 2.11 server each day. The culprit seems to be: [root@essnagios01 archives]# egrep "HOST ALERT:.*UP;HARD" nagios-05-28-2008-00.log | wc -l 97716 So I have 97716 entries each day looking like: [1211844162] HOST ALERT: sw-00-o2;UP;HARD;1;OK - 1.2.3.4: rta 1,069ms, lost 0% with the hostname of course being always different - every host comes up every minute. Does anyone have any clue if this is intended behaviour or what I may have done wrong?
