Xen XCP-ng
Xen/XCP-ng
Plugin: xenstat.plugin Module: xenstat.plugin
Overview
This collector monitors XenServer and XCP-ng host and domains statistics.
This collector is supported on all platforms.
This collector supports collecting metrics from multiple instances of this integration, including remote instances.
The plugin needs setuid.
Default Behavior
Auto-Detection
This plugin requires the xen-dom0-libs-devel and yajl-devel libraries to be installed.
Limits
The default configuration for this integration does not impose any limits on data collection.
Performance Impact
The default configuration for this integration is not expected to impose a significant performance impact on the system.
Setup
Prerequisites
Libraries
- Install
xen-dom0-libs-develandyajl-develusing the package manager of your system.
Note: On Cent-OS systems you will need centos-release-xen repository and the required package for xen is xen-devel
- Re-install Netdata from source. The installer will detect that the required libraries are now available and will also build xenstat.plugin.
Configuration
File
The configuration file name for this integration is netdata.conf.
Configuration for this specific integration is located in the [plugin:xenstat] section within that file.
The file format is a modified INI syntax. The general structure is:
[section1]
option1 = some value
option2 = some other value
[section2]
option3 = some third value
You can edit the configuration file using the edit-config script from the
Netdata config directory.
cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
sudo ./edit-config netdata.conf

Metrics
Metrics grouped by scope.
The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels.
Per Xen/XCP-ng instance
These metrics refer to the entire monitored application.
This scope has no labels.
Metrics:
| Metric | Dimensions | Unit |
|---|---|---|
| xenstat.mem | free, used | MiB |
| xenstat.domains | domains | domains |
| xenstat.cpus | cpus | cpus |
| xenstat.cpu_freq | frequency | MHz |
Per xendomain
Metrics related to Xen domains. Each domain provides its own set of the following metrics.
This scope has no labels.
Metrics:
| Metric | Dimensions | Unit |
|---|---|---|
| xendomain.states | running, blocked, paused, shutdown, crashed, dying | boolean |
| xendomain.cpu | used | percentage |
| xendomain.mem | maximum, current | MiB |
| xendomain.vcpu | a dimension per vcpu | percentage |
Per xendomain vbd
Metrics related to Xen domain Virtual Block Device. Each VBD provides its own set of the following metrics.
This scope has no labels.
Metrics:
| Metric | Dimensions | Unit |
|---|---|---|
| xendomain.oo_req_vbd | requests | requests/s |
| xendomain.requests_vbd | read, write | requests/s |
| xendomain.sectors_vbd | read, write | sectors/s |
Per xendomain network
Metrics related to Xen domain network interfaces. Each network interface provides its own set of the following metrics.
This scope has no labels.
Metrics:
| Metric | Dimensions | Unit |
|---|---|---|
| xendomain.bytes_network | received, sent | kilobits/s |
| xendomain.packets_network | received, sent | packets/s |
| xendomain.errors_network | received, sent | errors/s |
| xendomain.drops_network | received, sent | drops/s |
Alerts
There are no alerts configured by default for this integration.
