Hi All,
I would like to know if there is a downloadable AIX health check script available from IBM that would print a report of a servers health status.
I've been working on a number of Sun Solaris servers and Sun provide a sun checkup script which can give you an ORI figure as well as a list... (3 Replies)
Hi,
I have a server type(A group of AIX,HP-UX and Linux servers running with different appn) in which i need to do health check(memory,cpu,h/w etc). I am planning to automate the same. Please help me out in writing the same.
Thanks

Hi Everyone,
Can you please help me put together a aix health check script that will check the status of CPU,Memory,Adapter, Filesystems (threshold 80%) and Disks.Im thinking of deploying a script to gather the required data in all the 22 servers and probably send out a mail if anything needs... (3 Replies)
There are 3 servers . I want to fire commands df -kh and mpstat -P ALL on those individual servers and retrieve particular values to genrate reports. This part is almost done. But i am facing issue when i need to compile the reports from all three servers on to one server in order to generate a... (1 Reply)
Hi Experts,
I want to check health of hp-ux box.
Basically I want to check if there are possibilities of network/memory/cpu bottleneck?
Are there are any commands available other than glance in hp-ux for the same? (11 Replies)
need a script to check the health of a session server database. It must read the data base and send an alert if the database is unavailable. If its unavailable, we will want to bring down the database listener to force failover.
can u guyz help me in doing this. what information do i need... (1 Reply)
Hi everyone, I am new to the Unix admin position, needed some help. My management wants to report how their over all AIX servers / environment is doing so far. I've been researching and found multiple commands to run on each LPAR, well I have few questions and also wanted to share the commands Im... (12 Replies)

bup-margin
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.
