Re: [Nagios-users] Checking host up without ping
It's probably a bit late for this, but one of my servers used to be with a host that blocked pings, so I used check_ssh instead - if the SSH service responded, the server was up :) Andy.

Just use a host check that *can* determine whether the host is up or not. There's no rule that says a host check must be an ICMP ping. - Take Surveys. Earn Cash.

Re: [Nagios-users] WRONG STATUS
Also, in your check_ping command definition, you're requesting the host
respond within 30ms to be classed as up and OK.
This seems awfully quick - personally I request 1000ms (1 second) to
give it a fair amount of time to respond. If the host/router/whatever
is busy, it could take slightly longer than 30ms to reply, causing a
warning (or longer than 60ms to be 'down'.)

Hi Grace,
Try to increase max_check_attemps. Let nagios accept a host is in
DOWN status after at least 5 checks.
If it is important for you to be aware of a DOWN status of a host in
max. 2 minutes, then make nagios check intervals base on seconds
(instead of minutes). Then make max_check_attemps to be 6 but totally
taking 2 minutes with a delay of 20 seconds each.
Sorry for my English.

Re: [Nagios-users] NRPE 2.7.1 command_prefix problem
I've been looking at this some more today, and finally found the problem and solution! I added /dev/stdout 21 to the end of a command in my nrpe.cfg, and got the following result when running check_nrpe off my Nagios server: sudo: sorry, you must have a tty to run sudo. Looking at the /etc/sudoers file on the machine reveals a line Defaults requiretty. Commenting this out sorted the problem. For some reason, on a stock FC4 install, the sudoers file was virtually empty, yet in FC6 it was full of various settings! Andy.

[Nagios-users] is there a way to set host min_check_attempt?
Hi, (as to be numbers are only sample) We know that host assumed to be DOWN if host does not reply (or timeout) for 5 times successively (I mean 5 distinct checks in order). Do you know how to make nagios assume that host is UP only and only if host says OK to ping check for 5 times successively after a HARD-DOWN status? 2007/3/25, Andy Shellam [EMAIL PROTECTED]: Also, in your check_ping command definition, you're requesting the host respond within 30ms to be classed as up and OK.

[Nagios-users] Need help
Hi This is Mukta Sharma. I am masters student in GWU. I am doing Nagios installation and configuration during my Unix project. I am having one problem, after installing it. I followed all the steps written in the documentation to install Nagios. But after restarting my web server when i just want to verify if that changes working or not or i want to see the Nagios web interface, i entered the following path in to my web browser http://localhost/nagios/ . It asked me for the user name and password for Nagios Access at http://localhost. i have not entered any password, i just created the user as written in the documentation. So please anyone can tell me what i should do to resolve this problem. Thanks Mukta Sharma M.S Student The George Washington University - Take Surveys. Earn Cash.

You'll need to complete that process. Take a look at your Apache configuration, and any files you have specified there that it should use for authentication. - Take Surveys. Earn Cash.
