Dear Dan,
As a workaround you may use the following perl script written by Ullrich
Horlacher. It also demonstrates the basic idea where to get a containers uptime
from. Here he use a well known file, but I think one may also use the
information related to the containers init process.
lxc-uptime:
#!/usr/bin/perl -w
$uptime = `/usr/bin/uptime`;
@s = lstat '/dev/pts' or die $uptime;
$s = time - $s[10];
if ($s>172800) {
$d = int($s/86400);
$uptime =~ s/up .*?,/up $d days,/;
} else {
$h = int($s/3600);
$m = int(($s-$h*3600)/60);
$uptime =~ s/up .*?,/sprintf("up %02d:%02d,",$h,$m)/e;
}
print $uptime;
with greetings
Guido
