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.

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.

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.

Networking :: Changes On The Server Side Aren't Visible On The Client Side?

Jan 10, 2011

I'm using NFS and I have the following problem. After ~100 days, the client and server lose connection, but the client doesn't know about this, it gives no error. The problem is that the changes on the server side aren't visible on the client side.

The nfs options are: "noatime, nolock, hard, udp, notcp, nosuid, nodev, rsize=8192, wsize=8192, actimeo=60"

The kernel version is: built with 250 Hz. Is this an already corrected issue in a kernel version? Or are my options wrong?

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.

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.
