CentOS 5 :: Nagios - Checking Remote Host For Disk Space?

Nov 22, 2010

I'm trying to setup my test nagios to check the disk space of another linux box. I've got it setup and checking. But to my surprise, it was checking the nagios server's local disk space instead of the remote linux.

Here is my services.cfg.

define service{
use basic-service
name disk-space
check_command check_local_disk!20%!10%! /

Software :: Nagios, Checking Remote Services?

May 16, 2011

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.


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.

Server :: Nagios Passive Or Remote-host-side Alert?

Jan 6, 2010

Is 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.

Software :: Nagios: Free Disk Space : Invalid Drive?

Feb 19, 2010

We are using Nagios to monitor our servers. One of the items we monitor is the diskspace. We use the following code in our config file:

define service{
use generic-service,srv-pnp
host_name servername
service_description C: Drive Space
check_command check_nt!USEDDISKSPACE!-l c -w 80 -c 90

The check for the C-drive works fine. The check for the D-drive gives "Free disk space : Invalid drive".

General :: Checking Of Services In Nagios

Jul 29, 2010

checking of services in Nagios. You all know the check_[service] command right? In the commands.cfg and windows.cfg. To check for the different types of services/ports, we just replace the [service] in check_[service] with the name of the port? I only know of check_http, check_ssh, check_ftp etc. Some ports like Finger, snmp etc, all these we also write it as 'check_finger', 'check_snmp'? 2) And, if that is the case, do we have to install additional plugins to monitor the ports defined earlier? 3) Lastly, if i want to monitor finger,snmp in windows server, would i need to download any software?

Ubuntu :: Checking Disk Mean Checking All Partitions On Hd?

May 10, 2010

Sometimes at startup I get this message "Checking disk 1 of 1". Does that mean it's checking all partitions on the hd? After a bad shutdown there is no prompt for fsck to run and the system just boots up. In fstab I have both options set to "1" for the partition Ubuntu is on, all others set to "0". Any ideas on both?

CentOS 5 :: Install CentOS 5.2, And The Installation Ran Out Of Disk Space After Running For About 2 Hours?

Feb 18, 2010

I am trying to install CentOS 5.2, and the installation ran out of disk space after running for about 2 hours.I checked the FAQ, and it said 1.2 GB. The disk is 3 GB. The default install was selected, and I think that it checks for sufficient available disk space before installing. Still, it ran for quite a while before announcing that it was out of disk space.The Installation Guide is not very helpful, since there is a blank page where the disk space requirement is supposed to be. I just picked the default installation. A search of the forums on "not enough disk space" did not return much.

CentOS 5 :: Ssh_exchange_identification: Connection Closed By Remote Host?

Feb 3, 2011

I am having trouble connecting to one of the VM's through ssh from base machine all of a sudden. All I get is an error : ssh_exchange_identification: Connection closed by remote host

--IP/Hostname crossed out --
[root@XX-XX02 ~]# ssh -v 1XX.1X.5X.1XX
OpenSSH_4.3p2, OpenSSL 0.9.8e-fips-rhel5 01 Jul 2008[code].....

Saying that the problem is only with ssh would be wrong as I can't seem to telnet or ftp it either. But I can ping it fine.When I try to login to that VM through console, it won't even let me login. The screen would flash for a sec and the same login prompt would reappear. I am not sure what exactly happened as it was working fine before.

OS version: CentOS release 5.5 (Final)
uname -a: Linux XX.XX 2.6.18-194.17.1.el5 #1 SMP Wed Sep 29 12:50:31 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux

CentOS 5 Server :: Vsftpd - Takes Long Time To Login From Remote Host

Aug 19, 2009

I've setup vsftpd correctly and it's running fine with local users (in the same LAN). However, when remote users wanna login to the server, it takes more than 1 minute to get in. Users do can login from remote. It just took too long. (It prompted for the username and password very fast.) Since the server is behind a router, I did configure the port forwarding for TCP 20-21. The centos version is 5.3. The vsftpd is v2.0.5.

CentOS 5 :: Increased Disk Space Not Reflected

May 11, 2011

I am running Centos 5.5 in vmware and recently had to increase my disk space from 20GB to 40GB. I understand that in linux, the increased disk space is not automatically reflected but as I am new to this topic, I am not sure how I can go about doing this. how to see what's the available space and how I can partition(?) this.

For your reference:

[root@localhost ~]# fdisk -l
Disk /dev/sda: 42.9 GB, 42949672960 bytes
255 heads, 63 sectors/track, 5221 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

CentOS 5 :: Any Known Errors On Allocating Disk Space Using Rsync?

Mar 13, 2009

Need to know if there are any known errors allocating disk space using rsync. I have recently setup a small file backup server (2 500GB drives) running Centos 5.2, with a rsync daemon (via xinetd). However I have noticed that after about a week of usage, if I reboot, then the disk that rsync uses, has a lot of multiply claimed blocks and inode errors, such that I have to run fsck multiple times to fix. This has happened a couple of times now so I don't think that its random.

CentOS 5 :: Df Not Showing Disk Space After Logical Volume Expansion / Fix It?

Jun 5, 2009

I've added a new LUN to my Centos 5.2 server using Powerpath and have added it to an ext3 logical volume. I extended the logical volume using lvextend and the new space shows up correctly in lvdisplay. What I'm having problems with is getting Centos to see the new disk space (df -h shows 500GB, not 600GB as expected). I've tried running a resize2fs on the new volume but it tells me that "the filesystem is already n blocks long. Nothing to do". Does any one know where I'm going wrong? If possible I'd like to sort this without a reboot.

Software :: Nagios Reports Host As Down Services?

Apr 2, 2010

Since 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.
