[1]Artha	hey all
[1]Artha	I am doing check_by_ssh and on the UI I am getting "Usage: check_by_ssh -H <host> -C <command> [-fqv] [-1 "
RomainK	That means you're not passing check_by_ssh the right arguments.
RomainK	Double check your check_command and make sure it works from the command line as the nagios user.
[1]Artha	I did a test on the command line and found that nagios require GLIBC 2.8, and I am trying to monitor a redhat system that has GLIB 2.5
[1]Artha	yum report that is the latest version
[1]Artha	is there a way around?
RomainK	[1]Artha: the server you're trying to monitor doesn't need anything.
RomainK	Why would you install nagios on the server you're monitoring?
[1]Artha	I did not, all I did it copy the check_load to that box, and from the Nagios server I am doing check_by_ssh and execute that command
RomainK	Ah.
RomainK	They're not the same versions of the OS and you copied a binary  over..?
[1]Artha	for the command I am running: $USER1$/check_by_ssh -H $HOSTADDRESS$ -c "/home/nagios/bin/check_load -w $ARG1$ -c $ARG2$"
[1]Artha	yea
RomainK	you expected that to work?
RomainK	Anyway, you need to find a version of check_load that's compiled for that RH version, with the right deps.
[1]Artha	ah
[1]Artha	thank you, I have to track that down and see how I can get a version for RH
d_low	hey gang, can anyone help me with pnp4nagios
d_low	for some reason im getting squares for my graph labels... I think it might be a localization issue, but im not sure.
d_low	found it. missing deja-vu fonts
jmm	hi everyone.
sni	hi
jmm	I wish to improve my nagios setup, the problem is that some of the monitored host seems to have connections troubles, everyday it spam me with host down/host up alerts and notifications.Sometimes it's just for 1 or 2mn, but it can go to like 5.does got some ideas on how I should change my setup so it works better with such hosts ?
rubeus80	Hi I need to take all data from nagios events, including perfdata. nagios.log doesn'f fit our needs...just show changes. I tried status.dat but is not a log. You need to check timestamps for hosts and services. With 500 machines and 10 services per machine this is quite complicated and inneficient...This data must be integrated into a business intelligence app
rubeus80	I had a technical problem and quit...someone answered my previous question? if not sorry for this message
sni	no
sni	but it seems like you are looking for NDO or something similar
rubeus80	sni maybe..just trying ti figure if it was possible with logs
sni	like you said, the logs contain only the changes
rubeus80	no way to configure nagios to create a log with everything?
sni	i dont know your goal, but maybe the performance data written to a file would be enough too
sni	you may enable the debug log :)
rubeus80	lol
rubeus80	suicidal but who knows
sni	what are you trying to achieve?
rubeus80	sni we need to get if there is a change in a service or host state..nagios.log ok with that...but also to get all the performance data in real time (i mean when it's produced)
sni	nagios is capable of writing performance data to a extra logfile
rubeus80	ok
rubeus80	that would do the work
rubeus80	a lof for every service o host with perfdata or a single log?
sni	if thats enough for you, have a look at http://nagios.sourceforge.net/docs/3_0/perfdata.html
rubeus80	sni thank you very much
sni	depends on you configuration
rubeus80	you people are always helpful
rubeus80	:)
sni	especially the last chapter on that page
rubeus80	ok
rubeus80	I'll take a look
partner	seems to be quite quiet shift today :)
Zordrak	i am going crazy trying to work out why sudo nrpe calls are failing on a centos box. looking for help. everything done under an account called nrpe. su - to nrpe and this works fine:
Zordrak	/usr/bin/sudo /usr/lib64/nagios/plugins/check_hddtemp /dev/sda 40 50
Zordrak	nrpe cant do it on its own
Zordrak	running: strace -f /usr/sbin/nrpe -c /etc/nagios/nrpe.cfg -d
Zordrak	the only thing i can find is that just before the process exits it writes to fd2 (apparantly to nowhere since debug logging doesnt seem to log :/) "sudo: needs to be suid root"
Zordrak	/usr/bin/sudo is --s--x--x, check_hddtemp is root.nrpe rwsr-xr-x
jmm	what does ls -l /usr/bin/sudo tell ?
jmm	oh :)
Zordrak	/etc/sudoers is 0440
Zordrak	=everything -seems fine.. not to mention as i said logging in AS nrpe and running it works fine
Zordrak	but the daemon just keeps failing
Zordrak	the sudoers line: nrpe ALL=(root) NOPASSWD:/usr/lib64/nagios/plugins/check_hddtemp,{others}
Zordrak	selinux is disabled completely
Zordrak	hence.. im going crazy
jmm	how does looks your nagios config for that check ?
Zordrak	running manually from all over the place.. /location/of/check_nrpe -H host -c check_temp_sda
Zordrak	nrpe.cfg: command[check_temp_sda]=/usr/bin/sudo /usr/lib64/nagios/plugins/check_hddtemp /dev/sda 40 50
jmm	you could try to chmod +s check_hddtemp, but just to test.
jmm	so you can remove the call to sudo, and check if it's ok.
Zordrak	no joy
Zordrak	trying without sudo call
Zordrak	"UNKNOWN: please make sure script is running as root"
jmm	ENOLUCK.
Zordrak	(!)
Zordrak	running strace on the check_nrpe doesnt "seem" to get fed the sudo error.. looks like the connection is just killed which results in the normal "unable to read output". i assume this is just default behaviour when the daemon hits an abnormal exit
Zordrak	whats really baffling me is why it works manually under the nrpe account, but just not from the daemon itself
CapnDan	morning all!
CapnDan	what's the configuration for adding topology to Nagios called?
CapnDan	where you say, this set of hosts is "behind" this host?
CapnDan	(so if this host is down, don't bother alarming on all the stuff behind it)
jmm	CapnDan: look at the parent / child relation.
CapnDan	parents!! perfect, thanks!
jmm	yw.
Zordrak	maybe i might get *somewhere if i can get some log output
Zordrak	its set to log to syslog and debug.. but after the inital load, it doesnt spit a damn thing out to the log
Zordrak	jmm: fixed it
Zordrak	jmm: bloody stupid redhat defaults (hence why nearly everything runs slackware)
Zordrak	jmm: centos' sudoers file has "Defaults requiretty"
Zordrak	so, no tty login, no sudoers
Zordrak	and a stupid unrelated error msc
Zordrak	*msg
Zordrak	seems like i could solve a lot of my issues if i could somehow get nrpe to output STDERR from commands it runs
CapnDan	Whoaaa Nagos hosts map looks so much better with that "parents" topology added!
Valcor	CapnDan: shocking huh?
CapnDan	:-)
CapnDan	It's an iterative process, eh, I got all the important services in, enough to make my cowworkers go "oohhh" and "aaahhh" , now I can start adding the niceties.
CapnDan	The status map doesn't auto refresh or change colours when there are problems, does it?
LzrdKing	it shows when hosts are down
CapnDan	'k thanks.
LzrdKing	and yes, even throwing in dummy parents really makes a difference
Action: LzrdKing has dummy parents
CapnDan	lol
CapnDan	in this case I have an esx box with windows, linux, and solaris containers on it, and the Solaris container has zones in it, which themselves of course have services, so it works out beautifully.
LzrdKing	the vrml map is cool, but i can;t get to the nagios server from my windows vm to view it and all the vrmol viewers for my mac suck
LzrdKing	vrml*
LzrdKing	so i just do without it
LzrdKing	but seriously, my parents are cool
sni	i would like to add parents, i just don't know them :)
CapnDan	What is that? "3-D Status Map" ?? Mine doesn't work either.
Valcor	something not worh using
Valcor	requires a plugin for browsers to support VRML... and doesn't really give you anything worth it
LzrdKing	well it looks cool
sni	i would like to have a status map, based on host addresses
LzrdKing	vrml is so 1995
Valcor	LzrdKing: it does?
LzrdKing	Valcor:  in my opinion
CapnDan	screenshot of vrml display plz
LzrdKing	can't get one now :)
sni	i build my nagios without
Valcor	I don't think 3.2 includes it any more
sni	its really useless
LzrdKing	http://linux.yaroslavl.ru/docs/serv/nagios/vrml_test1.png
LzrdKing	it's in 3.2.0
LzrdKing	but there is no link, you have to go to statuswrl.cgi manually
Kalavera	hello
Kalavera	is there a way to split my configuration in files like a kind of include?
Valcor	Kalavera: yes
Valcor	http://nagios.sourceforge.net/docs/3_0/configmain.html
Valcor	cfg_file to load an individual file, or cfg_dir to load the entire directory
Valcor	but you should see samples of that already in your configuration
Kalavera	so in this way could I have a customer directory with their own host and services files?
CapnDan	Kalavera: sure, you can just include them in your main configuration.
LzrdKing	ohh, using a directory may me helpful to me...
Valcor	cfg_dir=/etc/nagios3/objects
Valcor	one entry, includes all .cfg files if they're under /etc/nagios3/objects
Valcor	recursively iirc
Valcor	what you do under that dir, nagios doesn't care, as long as it has permissions to the files/directories, and they are correct syntax... you're good to go
adurotec	Does anyone know why this is happening on a remote host: http://fpaste.org/LAt1/
Valcor	does the command exist in $HOME/libexec/check_disk?
Valcor	does the user nagios have rights to execute it?
keith4	holy shit
Zordrak	yup
Valcor	mislabelled the libexec dir?
Action: keith4 blinks
Valcor	adurotec: so does the user nagios, have a libexec directory in their $HOME directory?
adurotec	yes
CapnDan	Pet peeve of the day: explaining to Windows people that I don't have to tweak the memory of the Solaris server every time they start up a new application, or turn off an old one.
CapnDan	"How much phyiscal memory does it have?" "Never mind."  "But, i'll be adding..." "I know. Don't worry about it." "But (bla bla bla) two gigs .." "Don't worry about it."
CapnDan	Actually I'm taking entirely the wrong approach, I should be saying, "Thank you for telling me, I'll make the necessary adjustments to Solaris."
adurotec	is it possible to specify a different port for the plugin "check_https_url!10!20!/healthcheck" and if so where is this done?
Valcor	CapnDan: ahh you're finally catching on :)
Valcor	CapnDan: I've found it pointless arguing the same stuff over and over, and just tell them what they want to hear most of the time
Valcor	adurotec: you can either edit check_https_url command definition to use a different port, or you can add another argument to pass the port into the check command, or you can create another command
keith4	you should probably create a new one that takes a port parameter
adurotec	so something like -p "$ARG4$" appended to
Valcor	quotes not needed for the port number... but pretty much yes... then your call would append !portnum on the end
LzrdKing	does nagios log sending notifications?  i'm not getting them emailed to me anymore and i don;t know why
Valcor	LzrdKing: if you enable it yes
Valcor	http://nagios.sourceforge.net/docs/3_0/configmain.html
keith4	if it suddenly stopped... it's most likely a sendmail problem
LzrdKing	god, what order are those options in?  seems random
LzrdKing	is it possible to force nagios to send out a notification for testing?
CapnDan	LzrdKing: what do you mean?
Valcor	LzrdKing: you mean the test option under the service?
Valcor	"custom service notification"?
CapnDan	LzrdKing: yeah the different check_modules have totally different syntax.  Luckily all can be unified by the command{  } magic
LzrdKing	valcor: custom service notification is what i'm looking for, thanks!
keith4	you can just find your notification command, and run it manually
LzrdKing	ugh, no route to host...
LzrdKing	hooray! it was a nameserver issue
LzrdKing	nagios will once gain be spamming me
CapnDan	burn it out with fire!
LzrdKing	burn out nagios?
CapnDan	no, the nameserver
LzrdKing	i was using internal nameservers instead of external ones
CapnDan	BURN THEM
keith4	having part of your notification process depend on DNS is potentially dangerous
keith4	especially if you are bothering to check the DNS service
LzrdKing	of course it depends on dns to send internet email
LzrdKing	though it should be able to work locally...
LzrdKing	keith4: why dangerous, unless dns goes down?
RomainK	is it 5pm PST yet?
CapnDan	lol not for another 9 hours or so man
RomainK	:(
RomainK	That's what I was afraid of.
LzrdKing	no, only about 8 hours
CapnDan	hence the "or so" :-)
keith4	LzrdKing: for example... if you had used IP addresses for notification, you wouldn't have had your most recent problem
RomainK	IPs for notification?
RomainK	that's something I hadn't thought of.
RomainK	Wouldn't an IP-based smarthost be better?
keith4	yes
RomainK	or is that what you meant?
keith4	that's what i meant
Action: emias would usually prefer a local DNS server on the Nagios host.
emias	Alternatively, one could simply decide that DNS won't break, as we do.
Valcor	I'd still use an IP based smart host
Action: RomainK has done the DNS slave on nagios server thing before.
RomainK	But for the most part, I just used IP-based everything.
LzrdKing	i;m using procmail, it looks up the mx record when it sends mail
