Zenoss ZenTech Community

Once I set the user/password and installed all the dependencies (notably perl-libwww-perl.noarch), the server was properly modeled but with some issues:

- I get the "No data returned for command" message on my event log, tracing it on the logs running with debug, basically I do:

This is an extract of the logs, it's strange because some of the hosts display the data without issues while others just show no output

2014-11-14 10:01:42,346 DEBUG zen.zencommand: Datasource: VMwareGuest Received exit code: 0 Output:

Is there any way I can see the exact commands that are called So I can reproduce them Using the zencommand still lacks some information.

Hey,

you can run zencommand with the "showfullcommand" option.

E.g.:
zencommand run -v10 --showfullcommand

For an VMware Guest the command will be the following:
/usr/bin/perl /opt/zenoss/ZenPacks/ZenPacks.community.VMwareESXiMonitor-2.0.1-py2.7.egg/ZenPacks/community/VMwareESXiMonitor/libexec/esxi_monitor.pl --server --username --password --options 'guestperf:' | tail -n1

Thanks for your help, with this command I found three of the guest machines that don't show any output, I haven't figured yet what do they have in common, when I've got something I'll post it here.

Ok, I tracked it down to this code at the file esxi_monitor.pl

This call returns nothing and interrupts the execution of the code on certain circumstances
----
my $diskUsage = get_info($vm_view, $perfmgr_view, 'disk', 'usage', 'average');
----

Which is triggered by this code dying without any output
----
my $perf_data = $perfmgr_view->QueryPerf(querySpec => \@perf_query_spec);
----

So I guess there's something in that guest disk that provoking the issue (this disc is from a clonned guest but both are running normally according vmware console)

Hey,

I apologize for the delayed response.

I would love to spend more time writing ZenPacks and helping you guys, but payed job comes first. ;)

I'll try to reproduce the problem next week (by cloning a VM) and do some more debugging.

Thanks for your patience.

Hello, I have been looking at this, still no clue, even to the point that if I call twice the same command (extractred from the logs with the fullcommand flag) I get results only once for the guests where the scripts are working (never got any result on the nonworking ones)

Hey,

I cloned one of my VMs today and tried to reproduce without success...

Which Zenoss, vSphere SDK and ESXi versions are you using

I'll try to create a script which will dump the raw performance metrics returned by the ESXi Host.

But this might take a couple of days (still have to do some Christmas shopping). ;)
