help with datetimeinfo

natxoasenjo · ‎04-22-2015

hi,

this is probably a simple question but I do not seem to get it right.

With this code:

# get all esx hosts in Datacenter

my $esxhost_view = Vim::find_entity_views(

view_type => 'HostSystem',

properties =>

);

for my $host ( sort { $a->name cmp $b->name } @$esxhost_view ) {

    print $host->name . "\n";
    #print Dumper $host;
    print $host->config->dateTimeInfo;

}

I see I get all the required info from virtual center (both dumping it with Data::Dumper or with the --verbose flag on the script. But when I run it I keep getting:

Can't call method "dateTimeInfo" on an undefined value at bin/check_esx_time line 30.

How do I get to the ntp config of the esx hosts? I found the vmware health check (<a class="jive-link-external-small" href="https://github.com/lamw/vghetto-scripts/blob/master/perl/vmwareHealthCheck.pl">https://github.com/lamw/vghetto-scripts/blob/master/perl/vmwareHealthCheck.pl</a>) which seems to do the same I am attempting (see from line 1665) but no cookie.

Thanks in advance for any assistance.

sorry, I cannot seem to be able to edit this post and this forum messes with the code and has no preview button

# get all esx hosts in Datacenter
my $esxhost_view = Vim::find_entity_views(
    view_type  => 'HostSystem',
    properties => [ 'name', 'config.dateTimeInfo', ]
);

for my $host ( sort { $a->name cmp $b->name } @$esxhost_view ) {

    print $host->name . "\n";
    #print Dumper $host;
    print $host->config->dateTimeInfo;
}

not very pretty, but works:

my $ntpservers = $host->{'config.dateTimeInfo'}->ntpConfig->server; 
    for ( @$ntpservers ) {
        print $_ , "\n";
}

You figured it out, but because you asked for 'config.dateTimeInfo', it was stored as that hash key.

You could use the get_property() method in the SDK, which will sort of try both forms:

$host->get_property('config.dateTimeInfo')->ntpConfig->server;

Should also work:

$host->get_property('config.dateTimeInfo.ntpConfig.server');

I don't use it much personally, I sort of fall back on the usual Perl hash syntax.
