What's not working? Did it compile correctly? Nagios needs some extra packages to for all of its features to work. These can be installed via YUM even if you compile Nagios itself from source. Also, if you install Nagios from source, SELinux will prevent it from doing a lot of stuff by default. However, it's entirely possible to run Nagios with SELinux in Enforcing mode with the right policy. ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
[CentOS] list_add corruption problem
Howdy, I've got a CentOS 7 VM that occasionally becomes unresponsive. There's a "list_add corruption" entry in /var/log/messages, included below. This is on VMware. We have lots of other VMs which are running just fine. Only a few are CentOS 7 VMs, though, so I can't rule out some kind of environment issue. It's up-to-date on OS patches, and running kernel 3.10.0-514.26.2.el7.x86_64. When it locks up, there isn't any indication on its console, other than it looks like it's waiting at a login prompt. I did some Googling, which suggested similar issues have been around a while, but the results I found tended to be for CentOS 6 and older kernels. Can anyone help me understand what this means?

It's more time-consuming than hard to build a virtual machine these days, and it's not even that time-consuming. Is there a distro that already has what you want all packaged up? Run it in a VM. Take a snapshot first if you want to try something potentially system-breaking or that's going to spew files everywhere. On a single-user machine, the performance should be within a few percent of running on the bare metal. So, if you test drive some beta software and it doesn't perform well on a VM, it's probably not going to be much better running on a same-spec physical machine. NB: I administer several hundred virtual desktops, so I chugged rather than sipped the virtualization Kool-Aid. :-) -- -Chris ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

Since you can't have a file and a directory named "logs" in the same directory at the same time (that I know of), you could turn on bash's extended globbing. $ shopt -s extglob $ rm -rf !(logs) That will only preserve the top-level entity named logs, though.

Re: [CentOS] Nagios, getting started
On 6/22/2015 6:04 AM, Rob Kampen wrote:> What advantages does the RH/CentOS world have (if any?) over the ubuntu > LTS world? I can't think of any compelling reason to run Nagios on RHEL/CentOS if the rest of your shop is Ubuntu. If everyone there is familiar with Ubuntu, it'll be easier for them to troubleshoot a problem if they don't have to learn a new package manager at the same time. > If a vm is okay, what kind of RAM does it need? A VM is fine. I have Nagios monitoring 1,800 hosts and 17,000 services on a VM with 3 CPUs, 4GB of memory, and 20GB of storage. Whatever you do, set up MRTG graphing so you know how well Nagios is performing (http://nagios.sourceforge.net/docs/3_0/mrtggraphs.html) on your monitoring host. If you have many hosts and services to monitor, look in to the large installation tweaks and other advice in the tuning guide (http://nagios.sourceforge.net/docs/3_0/tuning.html). Also, Nagios causes constant disk activity temporarily storing and processing check results, so you can use a RAM disk to speed that up. > I see epel has nagios 3.5.1 with a date of 2013 for CentOS7 along with > plugins, is this the version folk use? - as the latest from nagios is 4.0.8 I still use 3.5.1. There was a compatibility break in 4.0 with Check_MK, an addition that's too valuable to lose. It's since been resolved, I think, but I haven't gotten around to upgrading yet. I will probably put it all together on a new CentOS 7 VM for maximum fun. > I am under orders to use packages and not compile, a viewpoint I endorse. > Are there other repos folk use? I use the distro package manager to manage Nagios' dependencies, but I compile Nagios myself for maximum control. It's really not that hard. What I would like to do next is get the best of both worlds and learn how to make my own Nagios RPM. > What about front ends, visualization etc.? I use Check_MK. It can replace Nagios' own configuration files, but I only use that part for several Linux hosts. However, the LiveStatus pages is a Swiss Army knife compared to the stock Nagios pages (which are still available). And it's FAST. I don't use any Nagios-specific add-ons for Nagios' config files. However, since they are still just text files, I use a programmer's text editor (SciTE), version control (git), and rsync to move config files from the dev Nagios host to the production Nagios host to the DR Nagios host. Both Check_MK's LiveStatus pages and SciTE understand regex searches. Unfortunately, they use different syntaxes, but once you get the hang of them they're invaluable. > Any comments about FAN? I don't know anything about FAN or any other Nagios configuration tools, but the moment you have to do something creative with your monitoring system will probably be the same moment you figure out it's not something automatic tools were programmed to cope with.

How about a cron job that e-mails you the output of 'service httpd status' or equivalent? You'll get a message that tells you if your web server is up or not. If you don't get a message, your mail server is down! (HHOS.) Unless you're just collecting performance or availability metrics for reports, how you intend to be notified is something to consider.

I didn't mean to imply that you use a multi-seat computer to get to a desktop served by a remote machine, though you could certainly do that if you wanted. Everyone still needs a machine to function as an endpoint for the remote desktop to be delivered to, though.

John is right. Laptops with integrated Intel video controllers have all the video processing power necessary for just about anything short of heavy gaming or real-time professional-level image processing. I run a virtual desktop infrastructure. A typical VDI host here will be running around 30 virtual desktops with dual displays at around 30% CPU utilization on 16 cores. Granted, you won't find those Xeons in any laptops, but those virtual desktops (running a full suite of business apps) AND their 60 displays are being emulated entirely in software, and then the display output is compressed and sent to the user over Ethernet, yet the users do not experience the dreadful video performance you describe being the result of not having discrete graphics. Also, each virtual desktop consumes about 3.5GB of memory (including its displays) on its host. The display memory isn't allocated directly as a number, but as a resolution. I seem to recall that it would take up to 128MB to support two 1920x1200 displays, however. -- -Chris ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] Spacewalk? Local repo? Cache?
I have a mix of CentOS 5, 6, and now 7 servers at work. There are enough of them now that it is starting to make sense for them to get updates from an internal source. I've seen RHN Satellite in years past. It looks like it may be a way to allow Windows admins here (familiar with WSUS) to update Linux boxes. A local repo might be easier to set up, but (as with Spacewalk) it seems like we'd end up with a lot of packages we don't need. A proxy and a sufficiently-large cache might do the trick if the first Linux box to get updates populates the cache which the files the others will need, but I haven't looked into this enough to see if there's even a way that works. How do you all keep a dozen or more Linux boxes updated?

For me, it provides a better experience than VNC, Radmin, RDP, PCoIP (even on a zero client device), and whatever VMware uses when you open a console in vSphere Client. That goes for speed and smoothness of display updates and even just copying and pasting text into the remote machine. -- -Chris Nothing in this message is intended to make or accept an offer or to form a contract, except that an attachment that is an image of a contract bearing the signature of an officer of our company may be or become a contract.

Re: [CentOS] Failing Network card

Try moving the network card to a new slot, especially if you can swap the network card with another card which is known to work. Also, try swapping the card into a spare server. If the problem follows the network card, then the card is probably bad. If a known-good card misbehaves in the slot where you previously had the network card, then the slot may be bad as well. -- -Chris Nothing in this message is intended to make or accept an offer or to form a contract, except that an attachment that is an image of a contract bearing the signature of an officer of our company may be or become a contract.
