General :: Parsing Through A Nagios Config File To Extract Info W/ Sed - Awk - Vi
Oct 13, 2010
I have a config file called hosts.cfg.
It contains entries like this:
Quote:
There are many more of these entries in the file, over 500, all in this same format: each host has a "define host" followed by 18 directives contained in squiggly brackets.
If I want to know all the hosts that are in the hostgroup called SERVER_GRP, I suppose I would need to read every hostgroups line (8th directive in squiggly brackets) that contains SERVER_GRP and output the corresponding host_name line (1st directive in squiggly brackets) from that entry.
I have a few questions to ask, so please pardon me
1) How to check for https in commands config file for Nagios? I only know how to check for http, not sure for https.
2) The log file in Nagios, is it possible to extend Nagios's plugins (or are there already have plugins existed) so that we could actually make use of the log file to check for status of each and every services in different hosts, instead of looking through the log file manually which can be very time-consuming if the list is very long.
We have a system called Skynet, which is basically a bunch of monitoring tools, including Nagios. What I want to do is output the status of 'critical' processes in conky. The conky part I'll worry about later (how hard can that be?), but I'm looking for some feedback on how I'm parsing the initial data. I figure that the simplest way to get the information is to query the cgi, then take what I need from the results...
All I basically want is the server name and the process name, the above example giving server0/server1 and 'update status' as the service. How would you go about extracting merely these two pieces of information, bearing in mind that the server name and process are variable?
I have a bash variable where the content looks like this where ;f1; and ;f2; are delimiters: ;f1;field1value1;f2;field2 value1 ;f1;field1value2;f2;field2 value2 ;f1;field1value3;f2;field2 value3
So what I need is to extract and put into variables each combination of f1 and f2 in a loop to something like that:
#first pass of the loop I need: f1=field1value1 f2=field2 value1
#second pass of the loop I need: f1=field1value2 f2=field2 value2
# third pass of the loop I need: f1=field1value3 f2=field2 value3
I need to get the modified date on a file in linux to use in a script.I tried using 'ls -l' on the file, but this caused problems when the date turned from a single digit into a double. The reason for the problem was because I was parsing the result string on spaces.How can I get the date of the last time a file was modified so I can use it in a script? For example, if a file was modified on 1/11/2010, I need the 11.
Running CentOS 5 KDE as a DNS Resolving Caching Name Server, Centos.myname.local ... I run PeerBlock with iBlock List, the 2 main ones which blocks everything, I may have to config it to allow connections. How is Nagios to install and setup. I use it at work, in the NOC and really love this software. 5 computers and a lot of devices using reserved IP's.
I'm trying to run extract-ikconfig because I've mistakenly deleted an old kernel config that I'd like to recover. However, when running the script from the latest (2.6.32.5) tree I run into this error:
Quote:
ERROR: Unable to extract kernel configuration information.
This kernel image may not have the config info.
Coincidentally, this happens with all of my kernel images. Is it a fixable problem? I should really set CONFIG_IKCONFIG_PROC next time..
I am using nessus to scan systems, and it generates the report file without any specific delimiter. Shown below is how a typical line in the file reads (It might show up as a very long line.
Code:
xx.xx.xx.xx|cpq-wbem (2301/tcp)|49272|REPORT|Synopsis :;;The remote web server is affected by multiple vulnerabilities.;;Description :;;According to its self-reported version number, the HP System;Management Homepage install on the remote host is earlier than 6.2. ;Such versions are reportedly affected by the following ;vulnerabilities :;; - Session renegotiations are not handled properly, which; could be exploited to insert
[code]....
The field of interest (for me) are IP ADDRESS, Synopsys, Description, Solution and Risk Factor. I tried the following command to parse this:
But this would not give desired results as ':;;' is not a standard delimiter and hence gives incorrect results. how to grab everything that occurs between the strings 'Synopsys', 'Description', 'Solution' & 'Risk factor' in the above example? In other words i may be asking to use multiple delimiters.. in the order of occurance.. is there a tool that supports multiple delimiters?
I'm working on a alias/script that will make it easier to look at my environment via the set command.
On my ubunto when running set it also displays some 10 pages of code pertaining to something called "imagemagik". at the end of the output. This code begins with the { character.
This is annoying if I want to look at my environment when working on scripts. How could I use something like grep, awk, sed, or whatever to ignore everything after the "{" character.
That seems to be the simplest way as long as there are no leading brackets in my environment. (And if you're thinking I should just remove {imagemagik}, I might just do that. But I still would like to know how to do this).
so i cannot install anything because update-info-dir file is missing from /var/lib/dpkg/info/ .. I've searched for the last day and a half for a way to fix this, but nothing. can't even update dpkg because of this. so how do I bypass or fix this so I can install stuff (this is a fresh install of ubuntu 10.04 lts Lucid Lynx).
I did some searches and after a few hours was able to get what I needed. What I didn't find was a fully encompased means of what I'm used to in the windows world in working with delimted files. Hopefully this is helpful to others and if there is something better or leaner way, even better.We have an issue where managing printers, just viewing on RHEL w/ sys-conf-prtr we lose any number of, up to ~30 printers from lpadmin. Rather than stare and compare to find the missing ones, I wanted to make an intuitive script. This is what I came up with.
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 looking to extract a config from a working kernel..that much was pretty easy..all ya gotta do is "cp /proc/config.gz ." which will put it in whatever directory you're currently in and then do a "gzip -d config.gz" to get the config file.
Now...after that it gets a bit tricky..Linus says you should never compile a kernel in /usr/src/ because those header files in ../include should never change. He says you should extract a new kernel gz in your home directory and compile it there. I tend to agree (who am I to argue?). Anyway..whereever your sources are this is where you need to copy the config file...
Like this...my home dir is "/home/dart". So I would put the kernel sources there under "/home/dart/linux". I would cd to /home/dart/linux and do "cp /proc/config.gz ." then "gzip -d config.gz" which should leave you with a file called "config", then "mv config .config"
Now here's where I run into a problem..when I do "make xconfig" I get this...
Tried to install the qt3-devel packages from CD but guess what? I ran into cdrom errors which is what I was trying to fix in the first **** place...catch 22 eh?
I know a .bin file is an executable file type in linux. We have an error after installing it and it referes to a file name and a line number within the file. I'm trying to find out if the file is part of the .bin file but I need a way to see what's inside of it or extract it.
and I want to extract VAR15 from each line (which can be at any column unfortunately - columns separated with commas - csv file), or VAR15 together with LATn,LONn from each line. Is it possible to do it with awk, grep or something other in linux?
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?
File in question is [URL].. meder@pc:~$ tar -xvjf wkhtmltopdf-0.10.0_rc2-static-i386.tar.bz2 bzip2: (stdin) is not a bzip2 file. tar: Child returned status 2 tar: Error exit delayed from previous errors
I tried to unzip it as well, and I tried a various slew of commands to no avail on my Debian box which has no GUI. I downloaded this on my local desktop ( Ubuntu ) and was able to easily extract w/ my mouse so I'm not exactly sure what the extractor did differently...
Im trying to extract the contents of a zip file but I want to extract it to my own directory. I'v tried -d from unzip but that just puts the contents of the zip into that directory.
But I want to extract the contents of the first (root) directory in the zip if there is only one directory in the root of the zip else just extract the files/folders in the root of the zip file (if there are more then one files).
e.g. test.zip contents the following dir structure:
test.zip /app_v1/ <-The contents of this directory I want extracted to a dir of my choice - folder-1 - folder-2 - folder-3 - folder-4 - file1 - file2
I stay in /var/www/upload and I want extract a file with tar command.
The output of tar xfvz /var/www/file.tar.gz is
Quote:
tar: /var/www/esempio.tar.bz2: funzione "open" non riuscita: Nessun file o directory tar: Errore irrimediabile: uscita immediata tar: Child returned status 2 tar: Uscita con stato di fallimento in base agli errori precedenti
I have a problem when I try to service nagios start, error is the following; No lock file found in /var/run/nagios.pid So when I verified the sample Nagios configuration files whit /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg, get: -bash: /usr/local/nagios/bin/nagios: No such file or directory
After an automatic update from Debian I get the following error while starting a root terminal: An error occurred while loading or saving configuration information for gnome-terminal. Some of your configuration settings may not work properly. Failed to contact configuration server: the most common cause is a missing or misconfigured D-bus session bus daemon.
I have an ISO CD image file and want to extract it's contents to a folder. I know there are ways to mount the image and stuff, but it's complicated. I'm looking for a GUI tool to open up the contets and extract needed files. On windows I would use WinRar to do this. K3B only allows me to burn the stuff, Arch does not work with ISO files :(Is there a similar tool on Linux, preferably from KDE world?
