Re: [PATCH] auvirt: a new tool for reporting events related to virtual machines



I'm also suppressing the AVC records. Maybe "--all-events" or "--show-all-events". What do you think?

I think you are on the right track.


I just added a "--full" option because libvirt can generate several
resource events and this can make the output confusing.
Hmm. Why not call it --resource if its a resource specific report? Full to me
implies everything for all guests.


$ ./auvirt
start guest-name-1    root    Tue Jan 10 11:05
stop  guest-name-1    root    Tue Jan 10 11:39
start guest-name-2    root    Wed Jan 11 15:23
start guest-name-2    root    Wed Jan 11 16:28
start guest-name-1    root    Wed Jan 12 19:47
Why not collapse these into 1 line like last that shows a duration?

start guest-name-1    root    Tue Jan 10 11:05 - 11:39 (00:34)

Do you have any samples for when a guest is paused and restarted? I would also
collapse those into a line showing the duration of the pause.

pause guest-name-1    root    Tue Jan 10 11:15 - 11:30 (00:15)


$ ./auvirt --show-uuid
start guest-name-1 fb4149f5-9ff6-4095-f6d3-a1d03936fdfa root    Tue Jan
10 11:05
stop  guest-name-1 fb4149f5-9ff6-4095-f6d3-a1d03936fdfa root    Tue Jan
10 11:39
start guest-name-2 f937029b-93ca-4e13-b40b-663f46323503 root    Wed Jan
11 15:23
start guest-name-2 f937029b-93ca-4e13-b40b-663f46323503 root    Wed Jan
11 16:28
start guest-name-1 fb4149f5-9ff6-4095-f6d3-a1d03936fdfa root    Wed Jan
12 19:47

$ ./auvirt --summary # keep the same behaviour

$ ./auvirt --uuid fb4149f5-9ff6-4095-f6d3-a1d03936fdfa
start guest-name-1    root    Tue Jan 10 11:05
stop  guest-name-1    root    Tue Jan 10 11:39
start guest-name-1    root    Wed Jan 12 19:47

$ ./auvirt --vm-name guest-name-2
start guest-name-2    root    Wed Jan 11 15:23
start guest-name-2    root    Wed Jan 11 16:28
Maybe it will be easier on admin's fingers to just call the above option --vm? I
like shorter names if they make sense and are unambiguous.


$ ./auvirt --full --uuid f937029b-93ca-4e13-b40b-663f46323503
res   guest-name-2    root    Wed Jan 11 15:23    disk    "?"
"/images/guest-2.img"
res   guest-name-2    root    Wed Jan 11 15:23    vcpu    "0"    "4"
res   guest-name-2    root    Wed Jan 11 15:23    net     "?"
"52:54:00:DB:AE:B4"
res   guest-name-2    root    Wed Jan 11 15:23    mem     "?"    "1048576"
start guest-name-2    root    Wed Jan 11 15:23
avc   guest-name-2    root    Wed Jan 11 19:49    read
"/images/guest-2.img"    denied
res   guest-name-2    root    Wed Jan 11 15:23    mem     "1048576"
"2097152"
stop  guest-name-2    root    Wed Jan 11 16:28
I would separate avcs and anomalies into a security report. Then for the
resource section, I would rearrange the fields so the time is at the end and then
show the duration so you collapse 2 lines (assignment and disposal) into 1 line.

For things that are disposed of at shutdown, you can just put "down" like last
does when users are logged out by the system shutdown.

Overall, I think this is heading in the right direction.

Thanks,
