[Nagios-users] hosts/services exposed to contact through groups
Hello, I have a contact (nagios_user1) listed in a host (host1) and service (service1) definition. As expected, that contact can only view that host and service in the Nagios web interface (nagios_user1 can view host1 and service1); nagios_user1 cannot view other hosts/services - again, this is expected. What's not expected is nagios_user1 can view other hosts/services when viewing the hosts groups/services groups pages for which nagios_user1 is not listed as a contact for. Selecting these hosts/services displays an unauthorized page but I'm looking to not expose those other hosts/services through the host groups/services groups pages. Thoughts, suggestions? -- Jacob -- Everyone hates slow websites. So do we.

[Nagios-users] hosts change from soft to hard state after first attempt
I am looking for some help tracking down what I think is potentially a timing bug or something of the sort. I show entries in my logs which look like this: [1327419369] HOST ALERT: testhost;DOWN;SOFT;1;CRITICAL - 10.11.12.13: rta nan, lost 100% [1327419369] HOST ALERT: testhost;DOWN;HARD;1;CRITICAL - 10.11.12.13: rta nan, lost 100% The host entry is configured as active on-demand (not scheduled) with a check attempts of 5. I see the above quite frequently where within the same second, it changes state to DOWN/SOFT 1/5 and then to DOWN/HARD 1/5. After performing some debugging, it appears that there are two service checks failing back-to-back and both scheduling a on-demand host check within fractions of a second. Looking through the codebase, it looks like there are provisions in place to abort a check if there is one already executing, but based on the output of the debug, there are two on-demand host checks being executed simultaneously. Any help would be appreciated. System is running Nagios 3.3.1 on RedHat ES5 32-bit.

Does your network use dynamic DNS by any chance? If you do, you could use the laptop's DNS name rather than its IP address. You may also be able to use a script that enumerates all the machines in the network. On Windows, look into the commands net view /Domain: and nbtstat -c as some starting points (Samba also has similar commands) Ken Tang wrote: I'd like to monitor a few user laptops in our environment. They use wireless so they often get dynamic IP addresses. Is there a way that Nagios can accept any connections, or, a range of addresses for a host? I don't have control of the DHCP server so I cannot assign a fixed IP address. -- Kevin Keane Owner The NetTech Find the Uncommon: Expert Solutions for a Network You Never Have to Think About Office: 866-642-7116 http://www.4nettech.com This e-mail and attachments, if any, may contain confidential and/or proprietary information.

[Nagios-users] Hosts are Critical
I am running CentOS 5 and I installed nagios thru yum using the RPMForge repository. When I log into the web interface, it shows my server as down/critical under hosts. Obviously since I'm accessing the host remotely via HTTP it isn't down. Any thoughts on how to fix this? Also, this was a clean install of the OS that I installed Apache, MySQL, PHP, and Nagios onto (including dependencies). Any help would be great.

I can't speak to the specifics of what RPMForge does for defaults but
generally, your host's check_command doesn't work or doesn't
accurately reflect the status of the host.
What is the Status Information?
What is the host{} definition?
What is the command{} definition it references as it's check_command?

An somewhat arbitrary guess is that the host check_command tries to
ping localhost and that doesn't work. Can you ping localhost as the
nagios user? If not, you may need to SUID /bin/ping so that it can be
run by non-root users.

Re: [Nagios-users] Hosts are Critical
Marc,
The status (of the host in Nagios) is down.
The host definition is:
define host{
use linux-server; Name of
host template$
; This host
definition $
; in (or
inherited by) $
host_name localhost
alias localhost
address 127.0.0.1
}
This is how it is out-of-the-box. How would I impliment a check_command?
Thanks,
Andy

Thanks, Andy yeah, that's probably the problem - nagios can't find / can't run the plugin. Make sure that the plugins are installed, nagios can run them, and nagios knows where they are. presumably you already installed the plugins through the RPMForge repository, so they should be executable by the nagios user. As for telling nagios where they are, you should have a commands file that defines commands. It'll use one the $USER$, most likely $USER1$. Edit resources.cfg and point $USER1$ (or whatever) to the correct location of your nagios plugins, which will be where you installed them.

[Nagios-users] Hosts report 'DOWN, HARD' after first attempt.
I am running a distributed monitoring system using Nagios 2.11 on FreeBSD 6.3. I use NSCA to send host and services events to the central server from the slave servers and have always had the following problem: A distributed server notices a host service is non-Ok and fires off check-host-alive. I have it set up to do check_ICMP and so it fires off five ICMP packets. Since the network isn't always perfect those five packets get dropped. However, I have my max_retry_interval set to 3 so it fires off another check_ICMP which completes just fine. As a result I see the following events take place on the slave server: [01-16-2009 15:18:46] HOST ALERT: s3200.blah.net;UP;SOFT;2;OK - 10.XX.XX.XX: rta 100.294ms, lost 0% [01-16-2009 15:18:46] HOST ALERT: s3200.blah.net;DOWN;SOFT;1;CRITICAL - 10.XX.XX.XX: rta nan, lost 100% However on the central server I see the following: [01-16-2009 15:19:02] HOST NOTIFICATION: NOC-email;s3200.blah.net;UP;host-notify-by-email;OK - 10.XX.XX.XX: rta 100.294ms, lost 0% [01-16-2009 15:19:01] HOST ALERT: s3200.blah.net;UP;HARD;1;OK - 10.XX.XX.XX: rta 100.294ms, lost 0% [01-16-2009 15:19:01] HOST NOTIFICATION: NOC-email;s3200.blah.net;DOWN;host-notify-by-email;CRITICAL - 10.XX.XX.XX: rta nan, lost 100% [01-16-2009 15:19:01] HOST ALERT: s3200.blah.net;DOWN;HARD;1;CRITICAL - 10.XX.XX.XX: rta nan, lost 100% The central server is immediately flagging the host as DOWN, HARD in spite of having the same max_retry_interval = 3 setting.

[Nagios-users] Hosts randomly disappearing
Hello All,
I have about 115 hosts in my nagios pool and I recently added a group of
7 UPSs. I made my own check using the check_snmp to check the load
percentage. Funny thing is, some times they show up in the host detail
and some times they do not. Refreshing a few times will get them to
show, then another refresh usually causes them to disappear. Opening one
of the hosts usually results in the message: Error: Host Status

I found this in the documentation: check_interval: NOTE: Do NOT enable regularly scheduled checks of a host unless you absolutely need to! Host checks are already performed on-demand when necessary, so there are few times when regularly scheduled checks would be needed. Regularly scheduled host checks can negatively impact performance - see the performance tuning tips for more information. This directive is used to define the number of time units between regularly scheduled checks of the host. Unless you've changed the interval_length directive from the default value of 60, this number will mean minutes. More information on this value can be found in the check scheduling documentation.

Re: [Nagios-users] hosts
What if there is one service (ping). Isn't it the same as having a check_interval on a host with no services? Depending on which version of Nagios you are running. Nagios 2.x host checks are run in series while Nagios 3.x most host checks are run in Parallel ( much faster as Nagios doesn't have to wait for the slow ping check to continue with everything else). So in Nagios 3.x it is similar to having it only check the host. But the logic of Nagios host and service checks are different. You should have a service check for ping and a host check with ping. And to your earlier question: You should check out Marc Powells post to the list earlier this year for some added insight to host checks keeping in mind that host checks are now performed faster in Nagios 3.x. http://article.gmane.org/gmane.network.nagios.user/52470 If you set the check_interval to be 0 disables regular checks or checks that are performed on a time interval. Nagios will then check the host if a service of the host is in a non-OK state. The documentation for the Nagios 3.x Service Check Scheduling has yet to be completed but you still might get some insight from the 2.x docs if you keep in mind the change in how host checks are executed http://nagios.sourceforge.net/docs/2_0/checkscheduling.html - Sponsored by: SourceForge.net Community Choice Awards: VOTE NOW!

I find it strange that a host could reboot and nagios not detect that outage. What version of nagios are you using? With nagios-2.x and prior, hosts are never checked unless a service on the host returns a non-OK result. Hosts are then checked with the host's check_command, up to max_check_attempts, with no pause between attempts. The end of that check process, which should be quick if you've followed the recommendations, will be the status of the host. It appears to me you might need to adjust your service check_interval to be less than the time it takes to reboot _or_ find a better way of knowing when the host reboots (uptime, timestamp on a file, log entries, etc...). -- Marc - This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.

Running nagios 3.0, I have set up a number (most) of my hosts without services, since all I am interested in monitoring is the hosts themselves.

Thanks. Nagios is a service monitoring application and everything is developed with that in mind. Every host is expected to have at least one service associated with it. Being able to effectively monitor hosts without services is new in Nagios-3 and is considered an 'optional' and not a core feature. The effects you're seeing are the result of that expectation. For example, clicking on the hostname link from hostgroup overview takes you to a list of services on that host. It would be nice if it did something different in your case but it's not there and you should understand that your use case is the exception, not the norm. I have heard nothing about that behavior changing in the future. -- Marc - This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.

And moving traffic; you might find it useful to ping-check other things on that switch. Or at least ssh-check the switch controller itself. Not to mention the rather large category of client machines, which we need to know are running so they can be backed up, and, of course, used for whatever the user needs. Kind of difficult to monitor the ability to run office, or an e-mail client :-). We still want to monitor the host, though, so that hopefully if/when a client machine should die we can fix it before the user (who may well come in before us in the morning) is impacted. We could, of course, monitor something like ssh on those machines, but why? All we (and the user) care about is that the machine is functioning. Sure. But for workstations, you're not monitoring diskspace? Open TCP listens (to watch for trojans) So yeah, while this may not be the way nagios is designed to work, and may never be (which I can live with if so), I really don't see this as being all that unusual a situation, as some responses seem to imply. Well, it's not that it's unusual, I think; I believe the assertion being made is that only doing a ping is not the Best Practice. Cheers, -- jra -- Jay R.

However, I would argue that cluttering up your nagios display with services that either a) are fringe cases which would be quickly noticed anyway, or b) which you really don't care about, not to mention the additional network, monitoring server, and client load this imposes, is not best practice.

Re: [Nagios-users] Hosts w/o services
Well, if you dig, I think you will find that you can monitor much more than you think. In fact, to take one example you mentioned: printers. If I was in charge of monitoring the availability of the boss's printer, I would have Nagios run a test printout every morning that would either return a status or, if it's an old printer that's less intelligent, I'd have a piece of paper in the output tray that I'd pick up on my way to my desk! At that point, you know not only that it's turned on, but that the toner is good, it's not jammed, and a bunch of other stuff. Even in the worst case scenario of a dot matrix printer connected via serial line, you can whip up a plugin that sends a printout via a command line tool with lpr or some other old standby. Samba might come in hand there. This may not be applicable to your printer, but for instance: [EMAIL PROTECTED] ~]$ /usr/lib/nagios/plugins/check_hpjd -h check_hpjd (nagios-plugins 1.4.8) 1.35 Copyright (c) 1999 Ethan Galstad [EMAIL PROTECTED] Copyright (c) 2000-2006 Nagios Plugin Development Team [EMAIL PROTECTED] This plugin tests the STATUS of an HP printer with a JetDirect card.

Re: [Nagios-users] Hosts w/o services
Hi, After reading this thread I just couldn't passed without commenting it. We also have this problem, we are an NREN and so a kind of ISP. We connect clients through rented lines and we want to monitor the lines we rent. How we can do this is simple: just ping the host in the other end of the line. It happens that these hosts are property of the client and so we don't have access to them or neither we care about the services they could have on them... (also, it was to complex to monitor services in multivendor hosts that we don't even know!) So we configured nagios 3.0.1 as we did since the old netsaint era, just created a service "ping", as been mentioned here before. The only difference is we disabled periodic host checks by setting the host check interval to 0. We also have a complex scenario here since we had setup a custom host_alive script to test hosts more time in after-hours time to don't have many false alarms to our night team. We do this with the new $ISVALIDTIME. (Thank you Nagios 3!! ;)) A final note on our monitoring experience is to only monitor services that are really important to us. I don't want to get my attention away of really hard problems with things that are not important to resolve. And that could be on a faulty state for weeks. Of course it depends on the size of the infrastructure you are monitoring, but I'm talking in hundreds of hosts and many more services.

Hey All, I am using version 2.9 currently and am noticing that when I ack a host/service and leave a comment and unchecked the persistent option that when the service or host changes states the acknowledgment comment is not being removed. I know that before I upgraded (was using 2.5) when I left a comment on acknowledging an alert and unchecked the persistent option the comment would automatically be removed when the host/service changed states. I'm not referring to the sticky acknowledgment which I know keeps the acks there across program restarts, I'm referring to the 3rd box under send notifications for the persistent option.

[Nagios-users] Hosts in PENDING State
Hello, I have several hosts configured with active checks enabled and the check_command set to check-host-alive which is defined in the command file. The state on these hosts always stays in pending unless I manually schedule a check. I noticed that in the sample localhost configuration there is a PING service that simply pings the host. Do I need to associate some sort of a service with each host before they will be checked? Is there something that I have missed in the documentation that will cause host checks to be recorded without associating a service with each host? I did see something similar in a GMane search, but the articles did not seem to be available. Regards, Andy Smith - Take Surveys. Earn Cash.

[Nagios-users] Hosts file - help
Hello,
Can I use an IP address instead of a DNS name for hosts in my
/usr/local/nagios/etc/servers/hosts.cfg file? Is this the only place
where I can define hosts to be monitored by Nagios? I can ping the host
below but cannot monitor it even when I use a fully qualified DNS name
for this host.
Currently, my host file looks like this:
define host {
use host-template
host_name 192.168.0.2
alias 192.168.0.2
address 192.168.0.2
}
define service {
use service-http
host_name 192.168.0.2
}
I have also tried:
define host {
use host-template
host_name dns.fmr.com
alias dns.fmr.com
address dns.fmr.com
}
define service {
use service-http
host_name dns.fmr.com
}
Do you see any config problems?
Thanks,
Zaeem.

[Nagios-users] Hosts checks not done when there is no service configured?
Hi there, I'm configuring Nagios and it seems that host-checks (check_command check-host-alive) aren't queued. I need to add a PING service on each host, to keep track of the uptime. Is this normal? I'd like to keep track of ISP routers at customers sites, so we can see if a fallout is caused by our devices or by the ISP.

Re: [Nagios-users] Hosts PENDING
I can't find the specific doc/FAQ that says so, but I know its been discussed here before: Every host needs a service. A host will not be checked if it doesn't have one. Even tho your host-check is probably a check_ping or check_icmp, add a _service_ to that host that does yet another check_ping or check_icmp. I doubt the extra bandwidth usage will kill your network. ;) I was bitten by this in my first installation too. -f On Thu, 2 Feb 2006, Patrick M.

Re: [Nagios-users] Hosts PENDING
Hi,
Actually you have to add the equipment to the service.cfg file. In fact you have to add a service for your equipment, if not, nagios will mark the host with pending status because is waiting for some service to monitor.
For example you have a router defined in hosts.cfg:
# 'router1' host definition
define host{
use generic-host ; Name of host template to use
host_name router1
alias Router #1
address 192.168.1.254
check_command check-host-alive
max_check_attempts 20
notification_interval 60
notification_period 24x7
notification_options d,u,r
}
Then you have to add the following into services.cfg to monitor the host:
# Service definition
define service{
use generic-service ; Name of service template to use
host_name router1
service_description PING
is_volatile 0
check_period 24x7
max_check_attempts 3
normal_check_interval 5
retry_check_interval 1
contact_groups router-admins
notification_interval 240
notification_period 24x7
notification_options c,r
check_command check_ping!100.0,20%!500.0,60%
}
The last configuration is the most simple monitor.
Hope it help.
Best Regards.
