Do you think proxmox server can support a lot of pings each a short
period of time?
Proxmox normally for sure, your network on the other side may be less
(latency wise).
As "worker" normally will be used for longer running tasks (a few
seconds to a few minutes, depends on the action and hardware) i think
polling once per second should be fast enough enough, and that is surely
hand-able by PVE.

If it's a call where a worker gets forked we have an UPID which
represents this action and we have a UPID wait function where you
can wait for this task to finish.
If you're making perl scripts on a PVE host it'd be really easy:
use PVE::API2::Qemu;
use PVE::ProcFSTools;
my $params = {
node => $nodename,
vmid => $id,
timeout => $shutdown_timeout,
forceStop => 1,
};
my $upid = PVE::API2::Qemu->vm_shutdown($params);
PVE::ProcFSTools::upid_wait($upid);
# more code here
But I'm simply guessing you do something else than perl.
But you get the UPID also when making API calls in another way
(through REST calls, e.g.) so you could check on that task.
You will almost always need a loop with waits somewhere but you
can make one function like upid_wait and use that everywhere.
To see how the UPID is calculated look at:
https://git.proxmox.com/?p=pve-common.git;a=blob;f=src/PVE/Tools.pm;h=9f08aa6fbf0c08da62e2f17078684cc2136d5b14;hb=HEAD#l854
For an upid_wait function implementation see;
https://git.proxmox.com/?p=pve-common.git;a=blob;f=src/PVE/ProcFSTools.pm;h=516c0e8b939791a64771df41c36df362e65c7423;hb=HEAD#l355
===== more easier approach ======
A bit complicated maybe, also polling the task (which is also
defined by the UPID) until it has "stopped" as status would be ok:
Something like (using pseudo code):
do {
sleep (1)
task = APICALL(get
nodes/nina/tasks/UPID:nina:00007F77:0029667A:56B36272:vncproxy:104:tom@pam:/status)
} while (task->{status} != 'stopped')

Hello list,
i'm using proxmox api to create Containers and managing ressources.
proxmox commands don't have a fixed duration so you need to
refresh calls to see that an action is correctly done..
Are there a method to catch the end of an action when using API
calls?
