Hi!
Some days ago, I discovered the 'xentop' tool (somebody mentioned it here:
http://discussions.citrix.com/topic/374218-what-can-we-do-to-decrease-the-time-needed-for-snapshot-reverts/
)
We work with XenServer 6.5 and we use long names for our virtual
machines to distinguish between them.
A machine name can have about 40 characters, but xentop displays only the first
10 characters in the NAME column. The result is, that I cannot identify a
particular VM using xentop.
I read the man page and googled around to find a solution. I found
the page
http://www.bl-nk.net/2014/07/xentop-and-long-server-names/
and created my own quirky solution as follows:
# cd /usr/sbin
# cp xentop xentop_wide
# sed -i 's/10\.10/80\.80/g' xentop_wide
This works for me today, but my common sense tells me that this solution could
cease working after we update to a newer version or that I could demage
some other instructions that accidentally have similar machine codes.
I discovered this 6 years old bug:
http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1591
The composer of this bug makes recommendations that I wouldn't recommend, so
that seams to be the reason why the bug is nearly 6 years old without being
solved.
I recommend a very simple and reconcilable problem-solving approach:
- The man page should contain / describe another option, let me call it
"-w / --column-name-width", which requires a number.
- When starting xentop with "-w 80" or "--column-name-width=80", then
it should display (in every imaginable work mode) a name column with
a width of 80 characters.
- The default width should stay of cause at 10 characters, but with such an
option, I as a user could have a choice.
Please tell me, how is the chance that such an bug fix enters a next possible
release of XenServer, which release number could this be and when will it
roughly appear?
Thanks in advance,
Michael Großer

For XenServer related bugs:
If you are a Citrix customer in which case you will have a Support contact
which you should use.
Otherwise the right place is somewhere on www.xenserver.org (forums, lists
etc), since that is a separate downstream project from xen.org
(xenproject).
For upstream/XenProject related buts:
xen-devel@lists.xen.org is the right place, the process/expectations are
described more fully at http://wiki.xen.org/wiki/Reporting_Bugs_against_Xen
.
At least in recent xen.org releases xentop takes a -f/--full-name option
which does not truncate the name:
root@st40:~# xentop -f -b
NAME STATE CPU(sec) CPU(%) MEM(k) MEM(%) MAXMEM(k) MAXMEM(%) VCPUS NETS NETTX(k) NETRX(k) VBDS VBD_OO VBD_RD VBD_WR VBD_RSECT VBD_WSECT SSID
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa -----r 56 0.0 524288 6.3 525312 6.3 1 1 53 1 2 0 1991 43 50738 824 0
Domain-0 -----r 308 0.0 522484 6.2 524288 6.3 8 0 0 0 0 0 0 0 0 0 0
So if this isn't present in XenServer then you want to be talking to them
or your Support person.
Ian.
