Someone started blocking icmp to a host we were monitoring. Once we noticed this, we switched over to check_tcp on a listening port. Now, when I look at the availability for this host, if I include any time since the icmp first starting getting blocked, I see only "indeterminate" indications. The log files show: First Host State Assumed (Faked Log Entry) Is there a way to force Nagios to recognize the server is up? Also, how do I get it sufficient data? As it is, the "undetermined" section of the availability log shows "Insufficient Data" for a period of over 9 days. This is longer than it took to get over the blocked icmp issue, so why is it complaining? Can it not gather sufficient data if we use check_tcp, rather than check_host?
