Hi Folks,
Nagios is acting a little weird for me, I have this external script which I hooked into Nagios, it merely does a curl/wget on a URL and returns the status based on string in the content/output. Initially for 2-3 hrs the script returns the right status and Nagios reports correctly i.e.... (4 Replies)

Hello,
I installed Nagios on the Centreon Platform <----"Centralized monitoring platform" anyways now every time i click on any of the tabs inside centreon interface, it gives me a Blank page, i have no idea what to do. i thought of resetting nagios to an earlier time when it was running... (2 Replies)
Hello Experts,
I have my windows servers located at different data-centers across US and I am monitoring all of them using Nagios server configured on a CentOS. All communications are done via public IP address and I doubt it can invite some security threats too. Can anyone let me know if it is... (3 Replies)
We have a dual Nagios server setup. One is setup for internal server monitoring on our LAN, while the second Nagios server is hosted externally and is used for external checks only such as URL and ping checks form the WAN side.
I was wondering if there is any way to setup cross dependencies... (1 Reply)
I'm having a problem scripting Expect to work as a Nagios check. The script runs fine from the cli, but not when run as a Nagios check. I turn on the debug output, and it looks like it's not seeing the whole buffer's worth of info, like it's paged interactively somehow. I'm new to Expect, but this... (1 Reply)

It's pretty simple, you just type two parameters to the script, check_ram -w 80 -c 90... (4 Replies)

bup-margin(1) General Commands Manual bup-margin(1)NAME
bup-margin - figure out your deduplication safety margin
SYNOPSIS
bup margin [options...]
DESCRIPTION
bup margin iterates through all objects in your bup repository, calculating the largest number of prefix bits shared between any two
entries. This number, n, identifies the longest subset of SHA-1 you could use and still encounter a collision between your object ids.
For example, one system that was tested had a collection of 11 million objects (70 GB), and bup margin returned 45. That means a 46-bit
hash would be sufficient to avoid all collisions among that set of objects; each object in that repository could be uniquely identified by
its first 46 bits.
The number of bits needed seems to increase by about 1 or 2 for every doubling of the number of objects. Since SHA-1 hashes have 160 bits,
that leaves 115 bits of margin. Of course, because SHA-1 hashes are essentially random, it's theoretically possible to use many more bits
with far fewer objects.
If you're paranoid about the possibility of SHA-1 collisions, you can monitor your repository by running bup margin occasionally to see if
you're getting dangerously close to 160 bits.
OPTIONS --predict
Guess the offset into each index file where a particular object will appear, and report the maximum deviation of the correct answer
from the guess. This is potentially useful for tuning an interpolation search algorithm.
--ignore-midx
don't use .midx files, use only .idx files. This is only really useful when used with --predict.
EXAMPLE
$ bup margin
Reading indexes: 100.00% (1612581/1612581), done.
40
40 matching prefix bits
1.94 bits per doubling
120 bits (61.86 doublings) remaining
4.19338e+18 times larger is possible
Everyone on earth could have 625878182 data sets
like yours, all in one repository, and we would
expect 1 object collision.
$ bup margin --predict
PackIdxList: using 1 index.
Reading indexes: 100.00% (1612581/1612581), done.
