General :: Nagios Installation And Configuration On RHEL 5
Apr 23, 2010
I am trying to install and configure nagios on RHEL 5. I have apache 2 installed and php all working as exepected. When i install nagios following the these steps [URL]. The nagios folder that is suppossed to be placed under apache2's httpd is no where to be seen. So when I try to open localhost/nagios/. It says: The requested URL /nagios/ was not found on this server. What can I do for the nagios to work on this system. The apache and php are working fine.
I have installed latest Nagios and Nagios plugins. Nagios is working properly, but when I go to the browser n write the www.server-name.com/nagios, it gives Not Found The requested URL /nagios/ was not found on this server. How can I tell Apache to open Nagios on adding /nagios in my URL.
We are planning to migrate our LINUX server from RHEL 3to RHEL 5. What are the configuration difference between RHEL 3 to RHEL 5 for webserver installations?
How to see the code behind the nagios plugin: Nagios Checker? I opened the folder which i have downloaded. After that where do i have to go to see the codes? Is it in App_Codes?
I have few doubts regarding fonts configuration in RHEL 5.4.
Code:
[vinay@linuxcoe4 fonts]$ cd /usr/share/X11/fonts [vinay@linuxcoe4 fonts]$ ls 100dpi 75dpi encodings misc TTF Type1 util
[code]....
Also there is no fonts.dir file, which describes fonts under a specific fonts directory in /usr/share/fonts tree. But we can find fonts.dir or fonts.scale file under /usr/share/X11/fonts/ tree. Does files under /usr/share/fonts tree are not dependent on fonts.dir ?
One monitor is working fine but the display is not coming on other monitor. I guess no problem in monitor because I swapped the cable to check the individual monitor. When I try to install the new driver its giving GCC-VERSION-CHECK while installing. And I do not think I have to install the new driver because it has already one. What should I do to configure the dual monitor. Do I have to edit any configuration file.
My system configuration details are below. Redhat version : Redhat Enterprise Linux WS release 3 (Taroon update 4) Driver in SRBC 26: NVIDIA-LINUX-x86_64-1.0-7664-pkg2.run Nvidia card model : Quadro fx p171 Bios version of Nvidia : 4.35.20.23.07 p/n : 900-50171-0400-0000K 600-50171-0002-201J
I am new to mysql can some one provide me the documentation or some recommended links to start the configuration of mysql server on RHEL. Also if I get the database schema, how can I replicate the same in my machine. Any documentation for this?
So we monitor all of our disk space, but only get pages for critical. What we would like to do is have one email sent to our team every month with all the "Warnings" for our disk. I have been searching and haven't found a way to do this. Any suggestions?
I've followed all the instructions in nagios documentation to install the nrpe agent in a remote host, but the daemon nrpe is not listening on port.. that means I can't even test it localhost!
netstat -at | grep nrpe returns nothing. You added the nrpe entry to your /etc/services file - done The only_from directive in the /etc/xinetd.d/nrpe file contains an entry for "127.0.0.1" - done xinetd is installed and started - done
Check the system log files for references about xinetd or nrpe and fix any problems that are reported - syslog empty..
Is there anything else I can do to correct this? I configured this yesterday and it was working ok.. but today when got into computer it stopped working
I am having individual Linux server and need to install nagios monitoring tool on the server. How to install on this linux server. I am using CentOS. Need to to monitor mysql and http services.
Running natios server in Debian 8? I cannot start nagios3 demon, it got following error:
Error: Check period '24x7' specified for service 'check ssh connection' on host 'testk2' is not defined anywhere! Error: Notification period '24x7' specified for service 'check ssh connection' on host 'testk2' is not defined anywhere!
But if I commented following statement in generic-service_nagios2.cfg, it works just fine.
I'm working hard with Nagios 3.0.4 on Debian Lenny. I have some questions. I can't find any information about these issues. I have hosts with a first_notification_delay of 60 minutes.And I have the whole day a Nagios controlling the same hosts. It's good to know if the same host is turned on during the night, but my work period begins at 10:00 am and it finish at 22:00 pm, I'm not a lucky boy I have configured a notification Period to 10:00 am to 22:00 pm.
Question 1: If a host goes into hard state CRITICAL, I know that Nagios waits 60 minutes to send a notification, but What happens if the host recovers before the first_notification_delay period ( for example, 30 min before)?Does it send the recovery notification or not?
Question 2: If a hard state happens at 21:59. Does Nagios wait until the 10:00 am of the day after to send the notification? If the host recovers at 9:00 am of the day after is the notification message cancelled?
Heare i come with Nagios Problem, When ever i stop nagios it say's
[root@x292 ~]# service nagios stop Stopping nagios: No lock file found in /usr/local/nagios/var/nagios.lock When ever i restart nagios it say's [root@x292 ~]# service nagios restart Running configuration check... CONFIG ERROR! Restart aborted. Check your Nagios configuration. my nagios.cfg file is # 'Nagios CFG 1'
I have an existing Nagios installation from before I started working here. It seems to be working well but my boss has just asked for a report of what servers and the associated processes/functions are being monitored. Is there any way to generate this report other than going through all the Nagios configuration files and putting it together manually?
can not ping from host (RHEL 6) to RHEL 5 in (virtual)? I have stopped iptables on both machines. But still not able to ping from host machine to virtual.
We have a client that is currently running Ultramonkey on their RHEL4.5 server (these are oracle application servers) for load balancing. We are currently busy with a project whereby we are upgrading their systems and one of the upgrades is to take their operating systems to RHEL5.4. I have downloaded the Ultramonkey rpm's from the website however this is specifically for RHEL 3. I am trying to get hold of the correct rpm's and installation process for RHEL5.4.
I am trying to download RHEL 5.4 AS version for testing..But under [URL] There is no specific link for AS version or ES version..How can I detect which iso is for AS and which one for ES..? There are separate links for AS and ES version for RHEL 4.x version but why is it not available for RHEL 5.x versions?
Friends i got an opertunity to configure ddns in my office.I already configured staic dns in linux, but this is the first time iam configuring ddns.I just configured ddns in rhel 5.2 in my office.So far every thing working fine,dhcp is giving ip address to the clients and both forward and reverse dns database is updating.
1) In windows we can use flushdns and registerdns commands to update the dns database, like this any command is in linux to update client details in dns database?
2)how to restrict multiple client entries keeping in dhcp database.
3)if i change client hostname it is not updating the dns database,it is keeping the old one.
I have few doubts regarding fonts configuration in RHEL 5.4.
Code: [vinay@linuxcoe4 fonts]$ cd /usr/share/X11/fonts [vinay@linuxcoe4 fonts]$ ls 100dpi 75dpi encodings misc TTF Type1 util [vinay@linuxcoe4 fonts]$ cd /usr/share/fonts/
[Code].....
What is the difference between fonts in /usr/share/X11/fonts and /usr/share/fonts
Also there is no fonts.dir file, which describes fonts under a specific fonts directory in /usr/share/fonts tree.
But we can find fonts.dir or fonts.scale file under /usr/share/X11/fonts/ tree. Does files under /usr/share/fonts tree are not dependent on fonts.dir ?
I believe that SU log messages are supposed to be appended to /var/log/messages but I'm not getting any log entries. I edited the /etc/syslog.conf and added the line below
su.* /var/log/sulog
Then ran /etc/rc.d/init.d/syslog restart (I also ran this prior to editing the syslog.conf file just in case). I'm still not getting any SU log messages.
I have and RHEL5.4 conecceted to an SAN HSV200. When I present a LUN to it, In system-confg-lvm gui appears a device like /dev/mapth/mapth0 (that�s the correct device to multipath) and other like /dev/sda or /dev/dm-N, as uninitialized entities. How could I configure to not display this device (/dev/sda) and prevent human errors?
This is the things I need:
1- I want (if it is posible...) to disappear the part where it says "uninitialized entities"
2- Is It necesary mantain the partitioning done to default (like /dev/mapper/mpath0p1) with device-mapper-multipath (kpartx command)? or Can I delete it without future problems?
I don't understand why after a successful installation of RHEL 5.3 in my PC (dual-boot with Windows XP x64), the hard disk just reads continously and my monitor.just went blackout. This happens (3x) everytime I setup it for the first time, re:detection of hardware,network, creation of a new user, etc. Although my GRUB is working perfectly.
I am trying to install RHEL 5.5 using rhel-server-5.5-i386-dvd DVD on my DELL Inspiron 1464 Laptop. However, after probing the hardware, I see a message at the bottom of the screen regarding xwindow, (cannot read it as it disappears fast) and then the first page of installation loads.(this has a redhat logo and a forward button at lower right corner) BUT this page is extremely DIM. Its as good as its not there.I have
