Plugin: charts.d.plugin Module: libreswan
Monitor Libreswan performance for optimal IPsec VPN operations. Improve your VPN operations with Netdata''s real-time metrics and built-in alerts.
The collector uses the
ipsec command to collect the information it needs.
This collector is supported on all platforms.
This collector supports collecting metrics from multiple instances of this integration, including remote instances.
This integration doesn't support auto-detection.
The default configuration for this integration does not impose any limits on data collection.
The default configuration for this integration is not expected to impose a significant performance impact on the system.
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 IPSEC tunnel
Metrics related to IPSEC tunnels. Each tunnel provides its own set of the following metrics.
This scope has no labels.
There are no alerts configured by default for this integration.
Install charts.d plugin
If using our official native DEB/RPM packages, make sure
netdata-plugin-chartsd is installed.
Permissions to execute
The plugin executes 2 commands to collect all the information it needs:
ipsec whack --status
ipsec whack --trafficstatus
The first command is used to extract the currently established tunnels, their IDs and their names. The second command is used to extract the current uptime and traffic.
Most probably user
netdata will not be able to query libreswan, so the
ipsec commands will be denied.
The plugin attempts to run
sudo ipsec ..., to get access to libreswan statistics.
To allow user
sudo ipsec ..., create the file
/etc/sudoers.d/netdata with this content:
netdata ALL = (root) NOPASSWD: /sbin/ipsec whack --status
netdata ALL = (root) NOPASSWD: /sbin/ipsec whack --trafficstatus
Make sure the path
/sbin/ipsec matches your setup (execute
which ipsec to find the right path).
The configuration file name for this integration is
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 charts.d/libreswan.conf
The config file is sourced by the charts.d plugin. It's a standard bash file.
The following collapsed table contains all the options that can be configured for the libreswan collector.

|libreswan_priority||The charts priority on the dashboard||90000||no|
|libreswan_retries||The number of retries to do in case of failure before disabling the collector.||10||no|

To troubleshoot issues with the
libreswan collector, run the
charts.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
charts.d.pluginto debug the collector:
./charts.d.plugin debug 1 libreswan
