Ubuntu :: Parsing Web Data From Nagios (Bash Fu)?
Apr 27, 2011
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...
Code:
wget -O - "http://user:pass@skynet/nagios/cgi-bin/status.cgi?status.cgi?host=all&servicestatustypes=16&hoststatustypes=3"| grep -i "<TD ALIGN=LEFT valign=center CLASS='statusBGCRITICAL'><A HREF='extinfo.cgi?type=2&host="
[Code]...
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 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.

fakeFile's contents :
Code:
blah $(date +%F) blah
fakeScript's contents :
Code:
while read line; do
echo $line
done < "fakeFile"
so here's the problem : is there any way to evaluate the fakeFile's contents (in the fakeScript), so that the term "$(date +%F)" (or any other bash script) in a string , translates to it's corresponding value ? (in this example , we want to have "blah current date" instead of " blah $(bash script) blah " )

I am looking for ways in where I could parse a web-page, say lURL... and need to parse data of the web-page. URL....Now, as can be seen the page has lot of information. I just need/want to only take the names of the packages rather than version numbers.

As a curious side project I'm playing with mzXML data(an xml format for holding mass spec data). A typical scan can be quite large, even up into GB size. I'm wondering how would one go about parsing an xml file in sections, one section at a time. The idea being if the computer doesn't have enough memory to load up the entire data file, work on chunks of it at a time.

as a result of a find command, i have
852065 72: /bin/gunzip
852065 72: /bin/gzip
852065 72: /bin/zcat
(the first column is inode number and the second is size if you're curious)
I want to be able to format it in a way such that:
852065 72:
/bin/gunzip
/bin/gzip
/bin/zcat
I know I can get the bottom half using awk- but I can't figure out how to extract the first set of numbers and get them to appear only once

I've searched online and found many examples using getopts, but nothing that clearly explains it use, nor any examples of what I'm trying to do. I have a script named "process". It can take from 0 to 3 different options. I'd like to be able to handle these options regardless of the order that they are entered.
Syntax:
process [-v] [-d #] [-h|-?] [string]
-v = verbose mode on
-d # = how deep to do the process, expecting a number parameter
-h or -? = show command usage
string = only process lines containing the specified string

playername4 password email #ofgames score setting1 setting2 setting3
playername5 password email #ofgames score setting1 setting2 setting3
I dont want to display everything, of course ^^, but how do i get the player name, the number of games he played and his score to display it in a webpage in this fasion:
Name Games Played Score
joe blow1 25 9876890
joe blow2 31 8989767
joe blow2 26 7989767
joe blow2 17 5989767

Is there a way to process individual characters one-by-one from a text file in Bash, or is that hoping for a little too much from this lovable old clunker?

I'm at the bottom of the bash learning curve, looking up, hoping someone can toss me a line. I need to update tracker on my system but this will erase the metatag database I've been building up over the course of months for the purpose of indexing a news archive. So the solution seems to be, 1) save the output of tracker-tag to a text file for all relevant files within a directory, 2) upgrade tracker (since the version in the Ubuntu repositories is very much out of date) and then 3) use a script to parse the text file and pass appropriate arguments back to tracker-tag to rebuild the database. It sounds as though it ought to be simple enough, but I need a push in the right direction, which hopefully will not be off the cliff. Before I confuse my metaphors any further, here's what the text file looks like.

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

PI'm trying to write a script to list all open ports in the MINIUNPND chain in iptables and use the procotol, port and destination ip to open ports on another router using upnpc.Here is the output of iptables -L MINIUPNPD
Code:
>iptables -L MINIUPNPD
Chain MINIUPNPD (1 references)
target prot opt source destination
ACCEPT tcp -- anywhere 192.168.3.124 tcp dpt:19955
ACCEPT tcp -- anywhere 192.168.3.124 tcp dpt:20054
ACCEPT tcp -- anywhere 192.168.3.130 udp dpt:10654
ACCEPT tcp -- anywhere 192.168.3.121 tcp dpt:29955
code....
No matter what i do i cant seem to remove the first 4 characters from the MYPROT array to leave only the digits. Also i cant seem to read the array back???
I thought it would simply be a loop reading each line and passing the fields in variables, executing upnpc commands i need then moving to the next line of the file until it reached the EOF.

set up BASH scripts on the server to automatically download and process data, and then upload it to my website. Is it even possible? Do servers allow website owners to place BASH scripts that can run automatically, or keep running indefinitely?

I have been trying to write a simple snip of bash shell code to import from 1 to 100 records into a Bash array.
I have a CSV file that is structured like:
record1,item1,item2,item3,item4
record2,item1,item2,item3,item4
record3,item1,item2,item3,item4
record4,item1,item2,item3,item4
And would like to get this data into corresponding arrays as such:
$record1[item1-4]
$record2[item1-4]
$record3[item1-4]
$record4[item1-4]

I have very little linux experience. And need some help with a bash script. I need to a script I can set cron to run to sort files out of a holding folder into final folders. It doesn't necessarily have to be bash, but I think it would be sufficient for this. File names are formatted as such when created: Dest-Date-Time-CID-Destination# I want the files to be moved from a all in one holding folder to a folder structure like this.
.../storage/year/month/day/Destination#/VarX(type)/hour/CID/'File'
I would need an if/else if/else statement to say if Dest = A set VarX = B If for example the file name was
infinity-20100927-17:00-1112223333-4445556666.wav
I would like the above file to end up moved from
.../holding
to
.../storage/2010/09/27/4445556666/Inbound/17/1112223333/infinity-20100927-17:00-1112223333-4445556666.wav
So the script will need to make directories based on information in the file name which is delimited by single dashes. Then move files from the holding folder to the newly created "sorted" folders.

I've reinstalled my system and installed apache. I've installed php5. 'a2enmod php5' returns with a message telling me that php5 is already enabled.
However, this code does not parse:
Code:
</php
phpinfo() ;
/>
I get a blank page. When I view the source code for the page, I see the php code.
How do I get php to work?

I have a new setup of 8.04 with Apache2, MSQL5 and PHP5.However, I can't get the PHP to run. It is NOT the common problem of the browser offering to download the files. In my case I have some PHP in an HTML file, but the PHP is just ignored.
I have played around with my httpd.conf and also php5.conf files, but I couldn't make any difference.
My httpd.conf sets the document root to /var/www and if I put a php file in here with command phpinfo(), then it seems to dispay correctly. My HTML files are /var/www/app/index.html

I have logs files from freeradius that have looks as follows:

Mon Aug 31 09:25:27 2009 : Auth: Login incorrect (rlm_ldap: User not found): [John Doe] (from client oficina port 0 via TLS tunnel)
[code]....
I use the following line to get the amount of users that don't exist on ldap:
Code:
grep "Login incorrect (rlm_ldap: User not found" /var/log/radius/radiusd-inner-tunnel-20090831.log | awk '{print $14}' | sort -fu | wc -l
Now, awk on line one for example parses [John Doe] and [Joon Williams] as "[John" and that it's not what I'd want. I mean how could I do for awk looks username field as closed between squared brackets?
