Adaptec RAID controller collector

Collects logical and physical devices metrics using arcconf command-line utility.

Executed commands:

sudo -n arcconf GETCONFIG 1 LD
sudo -n arcconf GETCONFIG 1 PD

Requirements

The module uses arcconf, which can only be executed by root. It uses sudo and assumes that it is configured such that the netdata user can execute arcconf as root without a password.

Add to your /etc/sudoers file:

which arcconf shows the full path to the binary.

netdata ALL=(root)       NOPASSWD: /path/to/arcconf

Reset Netdata's systemd unit CapabilityBoundingSet (Linux distributions with systemd)

The default CapabilityBoundingSet doesn't allow using sudo, and is quite strict in general. Resetting is not optimal, but a next-best solution given the inability to execute arcconf using sudo.

As the root user, do the following:

mkdir /etc/systemd/system/netdata.service.d
echo -e '[Service]\nCapabilityBoundingSet=~' | tee /etc/systemd/system/netdata.service.d/unset-capability-bounding-set.conf
systemctl daemon-reload
systemctl restart netdata.service

Enable the collector

The adaptec_raid collector is disabled by default. To enable it, use edit-config from the Netdata config directory, which is typically at /etc/netdata, to edit the python.d.conf file.

cd /etc/netdata   # Replace this path with your Netdata config directory, if different
sudo ./edit-config python.d.conf

Change the value of the adaptec_raid setting to yes. Save the file and restart the Netdata Agent with sudo systemctl restart netdata, or the appropriate method for your system.

Configuration

Edit the python.d/adaptec_raid.conf configuration file using edit-config from the Netdata config directory, which is typically at /etc/netdata.

cd /etc/netdata   # Replace this path with your Netdata config directory, if different
sudo ./edit-config python.d/adaptec_raid.conf

Troubleshooting

To troubleshoot issues with the adaptec_raid module, run the python.d.plugin with the debug option enabled. The output will give you the output of the data collection job or error messages on why the collector isn't working.

First, navigate to your plugins directory, usually they are located under /usr/libexec/netdata/plugins.d/. If that's not the case on your system, open netdata.conf and look for the setting plugins directory. Once you're in the plugin's directory, switch to the netdata user.

cd /usr/libexec/netdata/plugins.d/
sudo su -s /bin/bash netdata

Now you can manually run the adaptec_raid module in debug mode:

./python.d.plugin adaptec_raid debug trace
