Unix Script to get Kernel Parameters

[Former Member]

Hi All,

I need to create Unix Script on my SAP HP-Unix box using kctune command to fetch following Unix Kernel Parameters and write output to file:

msgmnb

msgtql

msgmni

shmmni

vx_ninode

vxfs_ifree_timelag

maxdsiz_64bit

maxssiz_64bit

pa_maxssiz_64bit

maxuprc

nproc

max_thread_proc

Please suggest me how can I write it, Concept is Script should fetch value of these Parameters and put output in a file on the server.

Regards,

Please provide output of kctune command as it is

then we can work on it because right now I don't have HP-UX access

Hi Ahmad,

Thanks for reply, I am also in phase of getting Unix access for Servers.

As per URL - http://h20000.www2.hp.com/bc/docs/support/SupportManual/c02259653/c02259653.pdf

We only need to put kctune as command to see all parameters. So now We only need to find how to put its output to file, Please tell me do you think below script will work -

#!/bin/csh

kctune > output.log

or what else need to be added.

yeah this will work and put all the content in the file.

I would like to append information each time in same file.

#!/bin/csh

date                                         >> /usr/sap/output123.log

/usr/sbin/kctune | grep msgmnb >> /usr/sap/output123.log

/usr/sbin/kctune | grep msgtql    >> /usr/sap/output123.log

/usr/sbin/kctune | grep msgmni  >> /usr/sap/output123.log

.....

like this for each parameter value

Hi Anand,

Thanks, Script is running as expected, Just one Last thing Can I update this script to get swap utilization, memory & CPU utilizations of the server.

Hey Shivam,

You can append lines like

/usr/sbin/swapinfo                  >> /usr/sap/output123.log

or other commands you want to use for each of them, its fine too
If you want to use glance for all of the 3 info then you need to use grep, cut to get precise info.

if you want me to do it for you then you need to provide exact output of glance.

Consider assiging points if it helps.

Shivam,

If your glance output is like this screenshot

usr/perf/bin/glance  | grep Glance  >> /usr/sap/output123.log

echo "--------------------------------------------------------------------------------------------------"  >> /usr/sap/output123.log

usr/perf/bin/glance | grep Util        >> /usr/sap/output123.log

~~

By these 3 lines you can get CPU, Disk, Memory and Swap information

Please verify the full path of glance command.

Thanks
