VMware vCenter Server is advanced server management software
that provides a centralized platform for controlling your VMware vSphere environments.
This module collects hosts and vms performance statistics from one or more
vCenter servers depending on configuration.
vspherecollector cannot re-login and continue collecting metrics after a vCenter reboot. go.d.plugin needs to be restarted.
All metrics have "vsphere." prefix.

password. Here is an example for 2 servers:
For all available options please see module configuration file.
Module supports filtering hosts and vms. Filtering options are
host_includeis a list of match patterns:
/Dc pattern[/Cluster pattern/Host pattern].
vm_includeis a list of match patterns:
/Dc pattern[/Cluster pattern/Host pattern/VM name].
Pattern should start with
/. It matches name,
syntax: simple patterns.
host_include: # filter all hosts
vm_include: # allow all vms
host_include: # allow all DC1 datacenter hosts and DC2 datacenter hosts except HOST2
- '/DC2/*/!HOST2 *'
vm_include: # allow all vms from datacenters whose names starts with DC1 and from all hosts except HOST1 and HOST2
- '/DC1*/*/!HOST1 !HOST2 */*'
update_every is 20 seconds, and it doesn't make sense to decrease the value. VMware real-time statistics are
generated at the 20-seconds specificity.
It is likely that 20 seconds is not enough for big installations and the value should be tuned.
To get better view we recommend to run the collector in debug mode and see how much time it will take to collect metrics.

There you can see that discovering took
525.614041ms, collecting metrics took
154.77997ms. Discovering is a separate
thread, it doesn't affect collecting.
timeout parameters should be adjusted based on these numbers.
To troubleshoot issues with the
vsphere collector, run the
go.d.plugin with the debug option enabled. The output
should give you clues as to why the collector isn't working.
Navigate to the
plugins.ddirectory, usually at
/usr/libexec/netdata/plugins.d/. If that's not the case on your system, open
netdata.confand look for the
Switch to the
sudo -u netdata -s
go.d.pluginto debug the collector:
./go.d.plugin -d -m vsphere
