How to tell how many linux running on z/VM?
We use vdisk for swap.
So I find :
q vdisk can tell me about the current running linux guests using Vdisk.
vmcp q vdisk |awk '{print($2)}' | sort -u

Re: How to tell how many linux running on z/VM?
That may be a good measure for some, including you; however, it is not
universal. We use V-disk for temp disks, so most of our CMS users have one or
more V-disks. We would have to filter the non-swap vdisks out of the results.
As noted, there is no one size fits all solution. You have to base your filters
on knowledge of your system, conventions, and user base. If you want it to be
nearly bullet-proof, you have to adopt some kind of convention and enforce it.
(I couldn't even use machine size if we were mixing IFLs and regular CPUs in an
LPAR - we have large, anywhere from 3.4 to 18 GB guests that are not Linux. In
that situation, we could base it on whether the guest was IFL or other).

Re: How to tell how many linux running on z/VM?
one simple command does it
Simple? I laugh in your general direction!
Also, this presupposes that the one asking the question has Velocity
Software performance products, and sufficient background z/VM performance
analysis to utilize them in this fashion.
The original question would seem to eliminate the second supposition.
That's not a flame at Sunny, experience comes from experience and it's
obvious that even experienced list members have come up with MANY
different ways to derive an answer.
I'm still waiting for Sunny to define the actual requirement more
thoroughly. To what use will this information be put?
Knowing that, an appropriate solution can be devised. Without that, it is
if senior management asked How many guests are running on z/VM? Without
knowing if they are talking about server consolidation, more about those
servers; or whether they want to know for many CMS users are still on the
box, etc., (imagination can run wild) -- who knows to what evil they might
put the answer?

Re: How to tell how many linux running on z/VM?
Gee, nothing works. You might as well have an EXEC like this: /* */ return random(1,99) /* Substitute whatever you like for the range. */ Kidding aside, establishing a naming convention and sticking to it is probably the best bet. That plus filtering based on the information from IND USER (IPL device/name and Virtual Storage) if you have those clever enough to IPL CMS in an otherwise Linux machine, should give you a pretty good idea of which are your Linux guests (so long as you avoid Levanta products :-) ) Regards, Richard Schuh -Original Message- From: The IBM z/VM Operating System [mailto:ib...@listserv.uark.edu] On Behalf Of Phil Smith III Sent: Friday, August 14, 2009 10:47 AM To: IBMVM@LISTSERV.UARK.EDU Subject: Re: How to tell how many linux running on z/VM?

Re: How to tell how many linux running on z/VM?
The question was how to tell how many Linux guests are running. Other types of users may inhabit the system. There are service machines (TCPIP, RSCS, etc.), operations machines (OPERATOR, OPERATNS, etc.), CMS users (MAINT, sysprog userids, etc.) that are included in the mix. If all you are counting are Linux guests, you need some way to either eliminate the non-Linux guests from the results of Q N, or to positively identify which guests are Linux. If you do not filter the results of Q N, then you might as well make it easy on yourself and use Q U, instead.

One more approach: set something distinctive for each guest -- a printer at address , a specific accounting code, etc. -- and use that (subject to other site restrictions, of course).

Q SIGNALS may be good, but you still need to filter out other users to be accurate. If I were to use the unfiltered response on my main system, I would get a result of 3.

A naming convention is probably the simplest way to ensure you get everything.. LNXx or what have you.

You can use PIPE CP Q N | SPLIT AT /,/ | STRIP | FIND LNX| count lines|consif you happen to use LNX as the prefix... Or keep a table - which in the end you need one in one form or another (even if a list of CP XAUTOLOG statements in AUTOLOG2 PROFILE EXEC).

Re: How to tell how many linux running on z/VM?
I count nine. Seriously, though; there's nothing there that indicates if a userid is running linux or some other utility. Being disconnected isn't significant, because someone could be connected to the console of one. I counted esaweb01 and 02 because I didn't recognize them any more than mlxap01s. I think that you use MLX as a prefix, but that'd be an internal standard, and not useful across customers. Ours tries to identify a customer in the first three characters, then P or D for production or dev. Then ZL for zlinux, then a two digit number. But it isn't totally consistent. I think that what is sought is a definitive, non shop specific way of counting linux images. -- Robert P. Nix Mayo Foundation.~.

Re: How to tell how many linux running on z/VM?
The first thing I don't like about this is that it is very prone to human error during the process of adding or removing images. This is just one more, in a long list of files, that has to be edited each time a guest is added. One more place for mistakes to be made. I'd first create a central, agree-upon definitive source for the image names and user ids. Ours are penguin files kept on autolog1 191. Every exec that needs to run through the list of images links Autolog1 191 and reads the penguin file for the system it's being run on. When a new image is added, the one penguin file needs to be edited, and all of the utilities and references immediately get the change, because they all use the same source for the information. If something's messed up, you know exactly where to look, and you know how many places it's messed up in: Just one. We run a two system CSE complex, so there are two penguin files, one for each CEC. They're used for everything from autologging the images during IPL to checking to see if they all are there or all ping. One stop shopping. -- Robert P. Nix Mayo Foundation.~.

You could use Q NSS NAME xxx MAP to find out how many CMS users (xxx=INSTSEG, CMSPIPES, or CMSVMLIB) and how many GCS users (xxx=GCS) there are an subtract from the Q USERS total to get a count of users running other operating systems (Linux, z/OS, VSE, TPF, etc) or no operatating system at all (eg: in a SYSTEM RESET state). Of course, if you've setup a shared DCSS for Linux guests, just query on that instead. Brian Nielsen Note: Don't use the CMS NSS or you will not exclude userids that did an IPL 190.)

If all the linux guests are configured to shutdown with the signal from CP SHUTDOWN, then count the number of userids listed in the response from CP Q SIGNALS SHUTDOWN, minus the number of SFS servers.

Re: How to tell how many linux running on z/VM?
Hi, Sunny. Some sites have guest naming standards (Linux guests are named LIN or LS., etc.) that would allow you to very simply see which guests were running Linux, as opposed to CMS or GCS. If your site doesn't have such a standard, then I'm afraid you're going to have to do this the hard way. I would download and install the TRACK z/VM utility; for each guest on the system, it can tell you what the IPL statement was, and if all of your Linux guest were IPLed off of a known DASD address, that would tell you which ones are indeed running Linux. To verify that the guest is a Linux one, TRACK can also display the kernel parm line, which is stored at a fixed location (x'1000'?) in the guest. This isn't too difficult to do for a handful of guests, but if you have a lot to query, you might want to consider automating this task via some Rexx TRACK macros. sunny...@wcb.ab.ca wrote: I was asked to find out how many linux guests are running on our z/VM? the cp commands:Q N is not very suitable for this question.

Re: How to tell how many linux running on z/VM?
If IPL device is sufficient, then it is not necessary to install TRACK. The IPL device or system is in the CP IND USER userid response, so a PIPE can be used to count all the userids IPL'ed by device, excluding the IPL 190 userids. -Original Message- From: The IBM z/VM Operating System [mailto:ib...@listserv.uark.edu] On Behalf Of Dave Jones Sent: Wednesday, August 12, 2009 4:13 PM To: IBMVM@LISTSERV.UARK.EDU Subject: Re: How to tell how many linux running on z/VM?

Re: How to tell how many linux running on z/VM?
That's true, Robert; I had forgotten that the IND command does show the last IPL statementof course, if some knuckle head had installed Linux on a virtual DASD at address 190, then that could pose a problem:-) Hodge, Robert L wrote: If IPL device is sufficient, then it is not necessary to install TRACK.

Re: How to tell how many linux running on z/VM?
Hi Sunny, Are you Linux guests autologed? If so then just check out the profile exec (or associated exec) for the Linux names there...should be unidentifiable by their IPL device numbers. --- On Wed, 8/12/09, sunny...@wcb.ab.ca sunny...@wcb.ab.ca wrote: From: sunny...@wcb.ab.ca sunny...@wcb.ab.ca Subject: How to tell how many linux running on z/VM?

Re: How to tell how many linux running on z/VM?
Strong incentive to make sure that either all of the linux guests IPL from the same virtual address or, at the very least, that none of them has a virtual 190. As long as you are using something fuzzy to make the determination, you can also see the virtual storage in the response to IND USER. CMS guests are usually measured in MB, not GB.

Re: How to tell how many linux running on z/VM?
I agree with Mark, why is the Q N command not suitable, maybe I am missing something or don't understand what Sunny is asking. I would just write a simple PIPE grabbing count them and write them to a file or to the console along with the count.

Re: How to tell how many linux running on z/VM?
And perhaps a set of clarifying questions: 1- do you mean those Linux guests logged on at a particular moment? 2- do you mean Linux guests defined in the directory? 3- do you care which are production, development, test, QA, or sandbox machines? Perhaps if you described the reason for the query, we can better describe solutions.

Re: How to tell how many linux running on z/VM?
A naming convention is probably the simplest way to ensure you get everything.. LNXx or what have you. Anything else is just guessing when it comes down to it, when talking about checking dynamically. You can use PIPE CP Q N | SPLIT AT /,/ | STRIP | FIND LNX| count lines|consif you happen to use LNX as the prefix... Or keep a table - which in the end you need one in one form or another (even if a list of CP XAUTOLOG statements in AUTOLOG2 PROFILE EXEC). What do you use to ensure the Linux guests are running when VM IPLs? Whatever it is, it is probably a good basis for counting how many are supposed to be running. Scott p.s. PIPE CP Q SIGNALS | DROP FIRST 2 | COUNT LINES | CONS -- can be pretty accurate in a pinch depending on what else uses signals.
