Re: [Nagios-users] can't get host to display in Host Detail panel
Actually the init script is not ran if you're running it via xinetd. you should look for server_args in /etc/xinet.d/nrpe (usually this is the file name) Diego On Thu, Oct 14, 2010 at 12:53 PM, Assaf Flatto wrote: > On 13/10/10 00:04, Jonathan Wiggins wrote: > > > > the place to look is in the nrpe init script , usually found in the > /etc/init.d directory > > you are looking for the NrpeCfg parameter . > > Make sure to point it to the nrpe.cfg file you found. > > Assaf > > but then I see this also in the logs > nrpe[11817]: Unable to open config file '/usr/local/nagios/etc/nrpe.cfg' for > reading > when I do a "locate nrpe.cfg", its only found in one location: > /etc/nagios/nrpe.cfg --- looking at that file below- looks normal to me, > and where is the application pulling this other nrpe.cfg location from, and > how to change it?

I followed this suggestion, shut down xinetd, ran nrpe as a stand-alone, also
added the nagios server in hosts.allow, and got good results (although no host
in control panel)

I had to take a break from this project, but now I'm circling back to it.
I am able to connect from the nagios server to the monitored node (this server
has (2) IP's as it's eth0 has an IP alias bound to it, hence checking both
IP's):
bash-3.1# /usr/local/nagios/libexec/check_nrpe -H 10.0.100.139
NRPE v2.12
bash-3.1# /usr/local/nagios/libexec/check_nrpe -H 10.0.100.138
NRPE v2.12
I can use another event handler:
bash-3.1# /usr/local/nagios/libexec/check_nrpe -H 10.0.100.139 -c check_users
USERS OK - 1 users currently logged in |users=1;5;10;0
bash-3.1# /usr/local/nagios/libexec/check_nrpe -H 10.0.100.138 -c check_users
USERS OK - 1 users currently logged in |users=1;5;10;0
I can also telnet from the Nagios server to the monitored host:
bash-3.1# telnet 10.0.100.139 5666
Trying 10.0.100.139...
Connected to 10.0.100.139 (10.0.100.139).
but...
I am still getting an SSL failure on the handshake?
Oct 11 19:12:43 mywebserverB nrpe[17659]: Error: Could not complete SSL
handshake
But back to xinetd; does seem that its not binding or starting with NRPE
correctly (not sure if this is why its not connecting)

Re: [Nagios-users] can't get host to display in Host Detail panel
Jonathan , lets take this from the top . You are trying to test on a remote server the amount of logged in users - that is done via nrpe . To test that is working you need to follow 3 major steps 1) make sure NRPE is installed and running on the remote machine . And accepting connections from the main nagios server * 2) make sure you have the nagios plugins installed on the remote machine .* 3) make sure the nrpe commands definitions point to the correct location of the plugins . once you followed the first 2 steps , you can test to see if the nrpe works by issuing the following command on the nagios server "/usr/local/nagios/libexec/check_nrpe -H -c check_users " If every thing is working - you should get the OK or any other result matching your criteria . If you get an error - about can not execute the command - log on to the remote host and recheck step 3. * read relevant documentation on http://www.nagios.org Assaf On 27/09/10 18:37, Jonathan Wiggins wrote: on the Nagios server, I didn't see the event handler, "check_users", I only saw a "check_local_users" in the commands.cfg file.

Hi Stuart
That line does exist, along with others, in the nrpe.cfg file
I run these, for example, and both give the same output:
/usr/lib64/nagios/plugins/check_nrpe -H localhost -c check_users
NRPE: Unable to read output
/usr/lib64/nagios/plugins/check_nrpe -H localhost -c check_load

do I actually need to supply arguments at the end of the check_nrpe command?

I have 3 web servers, and although they at one time all showed up successfully,
now one of them does not.
i have verified on the web server in question that nrpe is running and
listening on tcp/5666:
netstat -ntlp | grep nrpe

nrpe (pid 13920) is running...
I've checked the nrpe.cfg on another server that is showing up, and compared
b/t the two, and they look identical.
i've got an IPTables rule that allows connections on the web server:
-A RH-Firewall-1-INPUT -p tcp -m tcp --dport 5666 -j ACCEPT
One of the things that doesn't test right though is the check_nrpe command:

Re: [Nagios-users] can't get host to display in Host Detail panel
what's the command line that is called from nrpe when it's asked for a
'check_load' ? There should be a line similar to this in there:
command[check_load]=/usr/lib64/nagios/plugins/check_load -w 5,4,3 -c 8,6,4
Does this exist in the nrpe.cfg? If you run the command from your
configuration as the nrpe_user, does it execute and return a value properly?

Sep 21 13:30:08 mywebserver kernel: Removing netfilter NETLINK layer.
Sep 21 13:30:09 mywebserver kernel: ip_tables: (C) 2000-2006 Netfilter Core Team
Sep 21 13:30:10 mywebserver kernel: Netfilter messages via NETLINK v0.30.
Sep 21 13:30:10 mywebserver kernel: ip_conntrack version 2.4 (8192 buckets,
65536 max) - 304 bytes per conntrack
On the nagios server, i've checked the mywebserver.cfg file and it looks legit
and cross-compared with the two others, it seems identical (except for IP of
course):
# Host definition
# Modified 81610
define host{
use linux-server ; Inherit default values from a template
host_name mywebserver ; The name we're giving to this server
alias mywebserver ; A longer name for the server
address 10.0.100.139 ; IP address of the server
}
define service{
use generic-service
host_name mywebserver
service_description Home Page
check_command check_http!ww2
}
Any feedback, suggestions, thoughts, etc.. is much appreciated in advance

[Nagios-users] can't get host to display in Host Detail panel
I have 3 web servers, and although they at one time all showed up successfully,
now one of them does not.
i have verified on the web server in question that nrpe is running and
listening on tcp/5666:
netstat -ntlp | grep nrpe
tcp0 0 0.0.0.0:56660.0.0.0:*
LISTEN 13920/nrpe
/etc/init.d/nrpe status
nrpe (pid 13920) is running...
I've checked the nrpe.cfg on another server that is showing up, and compared
b/t the two, and they look identical.
i've got an IPTables rule that allows connections on the web server:
-A RH-Firewall-1-INPUT -p tcp -m tcp --dport 5666 -j ACCEPT
One of the things that doesn't test right though is the check_nrpe command:
/usr/lib64/nagios/plugins/check_nrpe -H localhost -c check_load
NRPE: Unable to read output
but tail /var/log/messages gives me something interesting, perhaps?
