Yesterday i install nagios, after that i can successfully monitor my local machine disk usage and its services, but now i want to monitor remote host, but have no idea how to do this , i also google alot but not getting resource full explanation.so please guys tell me how can i monitor the remote host using nagios..
View 54 Replies View RelatedIs this possible that a process running on a remote-host only inform nagios when some thing is wrong. Rather then nagios-monitoring-server checking through NRPE every so often. Reason is I want to add too many alerts in the application. And I don't want a whole list of ok messages.

Here is my services.cfg.

I just installed nagios to a Cent 5.4 box. Everything is working so far except I want to add a plugin I found on nagios exchange. The file has a .pl extension. I am unsure how to add the plugin to the rest of nagios. Do I need to add it to a nagios folder and then define it. If I just try to run the pl file I get a error mesg. I am unsure if the error is caused by system misconfig or because the plugin is not installed. The plugin is check_dayime.pl and the error I get is Can't locate Date/Parse.pm Perl seems to be working as I can run simple perl scripts and perl -v spits out v 5.8.8
View 3 Replies View RelatedI installed Nagios following the Quick Install method from the Nagios.org web site but now I would like to add and monitor another host.I don�t find a way , I have for example replaced the ip number of the localhost(127.0.0.1 localhost.cfg) for another ip number and I am able to monitor another computer that way. But then I no longer MONITOR the localhost unless I replace the ip number in the localhost.cfg file. what I would like to do is to monitor both or more computers.

Now how do i create web access to 3 of them, so that they can monitor only their server? Say, India shouls be able to see and monitor only India group, US guys should able to monitor only US servers. And they not be anle to access other group.
View 1 Replies View RelatedSince a week or 2 Nagios is constantly marking hosts (servers mainly but also a few Serial-over-IP converters) down for anything up to a few minutes. Typically, all services stay in OK status. Looking closer at a host in such state, it's status information is
CRITICAL - Packet Filtered (<IP address of host in question>)
in soft state. Sometimes services are in critical state with the host in OK status. Almost always the status information is "No route to host". Further checking shows no problems. Rarely this state lasts longer than one check interval. This started after a link was down, putting, correctly, all hosts and services on red for being unreachable. The link problems were solved within a few hours but Nagios only showed this after 2 reboots. Since then the problems has lessened in frequency gradually, from 5 to 10 of the 34 hosts being reported down at any given moment (the same for the 150-ish services monitored) to where I am now, 1 to 5 problem statuses (counting both hosts and services) and the occasional 'all green' screen. A week ago, when the problems were going a week already, Nagios updated from 3.2.0 to 3.2.1. This showed no apparent improvement.
Still, the Host Groups screen is not stable. A read or yellow status initially signified a problem to be looked at, right now it is likely a false alarm to will go away. Whenever the "packet filtered" or "no route to host" is followed up by a ping test, no problems, not even with the slightest delay or packt loss are found.
I have installed nagios successfully also able to monitor windows hosts. but not able to monitor linux hosts. i have follow below procedure, installation part and evertything was ok.but still i am not able to see linux host under nagios. i followed below url for monitor linux hosts on nagios.URL...
View 3 Replies View RelatedI am using nagios to monitor a local host and a remote host in a vmware, where both the machines working in CentOS. Now i need to monitor MySQL in my local host so that i should know whether MySQL is up and running. I came across some plugins like
check_MySQL_health
check_MySQL_status
check_MySQL_stat.
While i was trying to install check_MySQL_health, i cant get clear description about the installation and i got stuck with that.
I believe that I need to disable the host check, I'm checking a public FTP service and ping is disabled on that FTP host. This is resulting in Nagios reporting the host as down, but the service shows as OK.
Is there any way to disable the host check?
My question is about checking remote services under Nagios. I have installed nrpe and the standard plugins on my Nagios server (RHEL 5.4) and the systems I want to monitor. I have been able to create hostgroups. I am somewhat confused as to how to add a new service. I want to check to see if tomcat is running on the remote servers. I found a plugin check_procs. If I run the following command on one of the remotes it works.
Quote:
check_procs -u tomcat6
PROCS OK: 1 process with UID = 101 (tomcat6)[code].....
It doesn't work. I'm not sure how to format the service.I've found gobs of documentation on how to setup and install Nagios, done. I've not been so lucky on how to setup a new service.

I've trying to add a route to a host to force traffic out of a clustered IP address...
IE I have a cluster and the IP address moves from host to host on failure of a resource. The IP address is just a simple alias of an interface so for example... bond0:0 192.168.1.1 and bond0 192.168.1.10
What I want to do is force a program that starts up on the cluster hosts which sends packets out to a listening server to only send out of the cluster ip address.
I did a route add -host 172.22.2.2 gw 192.168.1.1. But this doesn't seem to work if i try to send a ping the packets still go out the wrong address, and more and above that for some reason the ping doesn't work at all. If i remove the route the ping will work again.
I have an automated setup (debian) which includes a startup script that rsyncs to a server (always the same server). Everything works well - just that I have to manually confirm that the host is supposed to be added to the known_hosts
Code:
The authenticity of host 'myserver.com (xx.xx.xx.xx)' can't be established.
RSA key fingerprint is 9b:ee:a6:47:hb:92:ac:76:81:94:18:7d:ad:8c:3e:25.

I am running 10.04 and am trying to add a route to a remote network using a gateway that is NOT on the local subnet. I am not messing with the default GW as all the other posts I can find are. I am using public IP addresses, but all of this is contained behind a firewall. I need to add a route to a private network (192.168.1.x) that is behind a router attached to a different subnet. The current routing table looks like this:
Code:
Destination Gateway Genmask Flags Metric Ref Use Iface
xxx.xxx.108.48 0.0.0.0 255.255.255.240 U 1 0 0 eth0
0.0.0.0 xxx.xxx.108.49 0.0.0.0 UG 0 0 0 eth0
The remote network is 192.168.1.0/24 and it is reachable via xxx.xxx.37.203. I can ping the gateway no problem. However when I try to add a route to this network I get an error.
route add -net 192.168.1.0 netmask 255.255.255.0 gw xxx.xxx.37.203
SIOCADDRT: No such process
I assume this is because the GW is not on the local subnet. When I try this on a machine that is connected to the xxx.xxx.37 network, everything works fine and I can reach the remote network. I even tried adding a static route to the gateway, but that did not help.
route add -host xxx.xxx.37.203 gw xxx.xxx.108.49
From a Fedora 9 server (I think!) I'm trying to mount an nfs drive from a Mac Server. You see, a couple weeks back this was working fine but now there seems to be a problem. I've tried using the mount command and found the following line in the /etc/fstab doc...
Code:
<IP ADDRESS>:/remote/nfs/directory /directory/to/mount/on nfs defaults 0 0
It was commented so I uncommented it, hoping this would be a quick and easy resolution =). Anyway, it didn't work and when I run mount -av the server timesout. So on the Mac Server, I enabled Samba sharing preferences and tried adding this to fstab,
Code:
<IP ADDRESS>:/remote/nfs/directory /directory/to/mount/on cifs username=name,password=password 0 0
When I run mount -a it hangs. I guess I'm doing everything totally wrong. I can SSH into the MAC Server and use tar, rsync etc with no problem. But I really need this drive to mount as it once use to. It's been suggested to me that the NFS or networking module on the Linux box might be broken.

I have installed Nagios 3 on CentOS 5.2. Everything is running. It is monitoring 10 machines and 60 services for now. Now I want email notifications for the critical alerts from Nagios. I am already having one mail server (Qmail) running on different machine and I want to use its reference to send alerts to my network.

View 1 Replies View RelatedI have a box (boell) running Fedora 10 sitting behind a firewall at school. I am able to freely ssh to and from this box to other computers (minion) within that lan. Outside of this network I cannot directly ssh to boell - I must ssh first to minion, then I can ssh to boell. I've spoken with the sysadmin and he's verified that the firewall permits ssh freely - i haven't had any issues like this with other boxes of mine there, so this isn't any surprise.
I have verified that the hosts.deny file is blank, iptables permits ports 22 (and 80) and I didn't see anything obvious in the sshd_config. I tried a tcp dump on the external host and boell while attempting to ssh from the former to boell. The packets appear to be acknowledged by boell, but this fails to lead to a connection. I've tried this process with external hosts in different locations with the same result. I have made few modifications to the default installation for F10, so perhaps there is some default somewhere I have to change. In any case, below I have attached excerpts of germane files.

i have a udp server running at port 60178. when i connect to it from localhost there is no problem. when i use the client from a remote host i am not able to connect. I changed my server firewall settings[Fedora 11] and added "udp 60178" to trusted ports but still nothing happened. I ran wireshark and observed that packets are coming to the server machine but server returns a "Port Unreachable" ICMP message and doesnt give the packet to the application.
