Obviously Nagios will page out once for each host and service goes down. But, is there a way to configure it to page out once, kind of like "Hey, LOTS of stuff just went down." Rather than 200+ individual pages?

View 3 Replies View RelatedI am trying to set up Nagios to monitor four machines in my local network. I set up one of the remote machines to use the check_nrpe plugin. When trying to start Nagios it says it cannot find the plugin. I have included a locate for check_nrpe and check_ping (a plugin that IS found). I do not know if the problem is in Fedora, Nagios, or ELBKS (error lies between keyboard and seat). I have checked permissions on the two check_ plugins and they are identical. Here is the terminal log: [root@Linux04 wegemer]# nagios /etc/nagios/nagios.cfg

When you first access Nagios, it displays the Home page (the Nagios Core version and check for updates page). I would like to have a way to change the default page to either the Tactical Overview display or the Services display.This question was asked here, but not answered

I have this scenario.
Nagios Server - 192.168.1.200
Nagios Client - 192.168.1.201 (This is the remote-host I am trying to monitor)

I need to find a solution where I can monitor multiple sites at once and know when they go down. There are fraudulent sites (not mine I am in the infosec industry)
I have been playing with Nagios and Zabbix all day with not much luck. I have managed to get both installed and running and researched for hours. I just need to figure out how to add domain names to be monitored and I am stuck. I know you have to do it in the conf files but I cannot get a domain to show up?
How can we run the linux process like tar on multiple core? For example if we want to build the kernel we can use -j4 to distribute process of 4 different core. Is it possible to run long time consuming process on mulitple core?
View 1 Replies View RelatedWhenever I monitor my CPU's, it seems only the first is ever utilized, with the second always being at 0%.Does this mean it is not being used, or just not being reported as in use?Is there anything I could do to improve the situation if it is not being used as much as it could be?On Windows, I can assign processes to both cores, or either one. Is there a way to do something similar in Linux?

But he does not give a name for the formula. Does anyone happen to know what it is called? I need to do some related research.
I have an interesting issue with simple scan. When I scan a single page document, the exposure is not very good because there are dark and light areas scattered over the entire document. Of course, one cannot adjust these settings in simple scan as one can with xsane. However, I noticed if I scanned a multiple page document, all pages after the first seemed to be more consistent and the exposure was fairly good (exposure here referring to all the aspects accessable in xsane such as brightness, contrast, gamma, etc.)
So I tried a little experiment. I scanned a single page document as if it were a multiple page document by scanning the document multiple times in the same session.The same thing occurs as if one were scanning a multiple document: the first page is mottled, but all pages after are much better scans. What is happening here?
I have a page which is going to be internationalized, and available in more languages. It contains PHP scripts to load, let's say, current user's data from database and the internationalized content itself, like "Welcome user" message. The problem for me is the fact, that internationalized content is not continual, and it's all over the page mixed with php scripts.
I don't want to use eval(). I've got 2 , they are, however, not good enough. 1. One file per language version, with scripts included - there will be many languages, so there would have to be many files with redundant data. Also if I wanted to change structure of script, I would have to change it in all pages. 2. Load international data from db, while scripts are on the page - not sure about good database structure I mean, how would I get the right content from database? (content would be split into rows, columns, or something?)

Ive installed apache2 on the new server and moved all the files from one server to the other. I'm making tests in my local lan so I've edited my computer's hosts file to point to the name of each site to the local ip of the new server:
192.168.1.85 www.mypage.com
192.168.1.85 svn.mypage.com

I have all the site definition files in /etc/apache2/sites-available I also have the used a2ensite to enable each page.

I am using Xfce as the desktop enviroment and Mozilla Firefox as the webrowser. Within the webrowser window, I do File>Save Page As. I save it, and the result is almost always foo.html and directory foo_files. But I think under KDE I could choose the format, one of them being something like "Single page" (only one file; the colecction of .png, etc is embedded into that file). And this is the format I want Xfce (or Firefox) to use when downloading to hdd.
View 1 Replies View RelatedIn my logs for Apache I have lots and lots of failed attempts for incorrect incarnations of [URL]. None of them are anywhere near my alias for the index.php but yet phpmyadmin is broken. Is there away I can mess up robots like this. Send IP's that create multiple wrong page requests on my server back to their own IP address maybe? I would then just set thresholds to decide how strict to be. I did try fail-to-ban before but it is cryptic. I don't have it on this particular server.

View 14 Replies View RelatedI've been looking though different editors for one that has good printing support. Ideally it should be able to print C++ code with line numbers, syntax highlighting, multiple columns per page, customizable fonts and sizes and a print preview feature so that I can make sure it looks right before sending it to the printer. It appears that notepad++ had at least some of these features, but it is not available on linux. The best I could do so far is to copy/paste the output of 'cat -n foo.cpp' into oowriter and format it into two colums. I don't get synax highlighting though and I have to manually replace tabs with a few spaces as well as some excessive leading spaces before the line numbering.

View 6 Replies View RelatedComing in Linux 2.6.39 but probably really here under your nose in 2.6.38: mblk_io_submit
Ext4 will now by default use the "Multiple Page-IO Submissions" mblk_io_submit option, which is said to considerably improve performance and scalability. The code behind it was already added to the kernel with version 2.6.37; however, just before this Linux version was finalised, the Ext developers disabled the function by default because it caused data corruption in certain situations; the responsible bug was fixed in the stabilisation phase of 2.6.38.So is that true? Does 2.6.38 have a deactivated-but-perfectly-usable EXT4 file system performance option by the name of mblk_io_submit? On Natty (well really Lucid running a back-port of 2.6.38 but Natty should be even easier) I added it to /etc/fstab like this:
Code:
/dev/mapper/vg0-lv0 / ext4 mblk_io_submit,relatime,errors=remount-ro 0 1
and rebooted. The system (really a VM) had no issues at all
Code:
$ dmesg | grep -i ext4
[ 3.363201] EXT4-fs (dm-1): mounted filesystem with ordered data mode. Opts: (null)

I have a command line OCR program called OCR Shop XTR (Vividata corp) that I am using on a system with a 6-core AMD chip. I changed the bios so that the 6-cores were activated, but htop shows me that while the program is running, I am only getting activity on one core (the program maxes out the one core with consistent usage between 97% and 100%).
I have read that many programs are not written to take advantage of multiple core cpu's. However, I am just hoping that there is some way to get this program to take advantage of the extra cores. Does anyone know of a way to invoke programs from the command line which would spread the workload out among additional cores?

I recently read in a forum that by default the Linux kernel only activates one of two cores in a dual core processor. Searching online gave one option to find out and that was the mpstat command. I therefore ran the command and got the following output.As the result says, it shows only 1 cpu. I was wondering what I could do to activate both cores in my machine, and whether doing so was going to cause me any problems.
