AdaptecRAID

Plugin: python.d.plugin Module: adaptec_raid

Overview

This collector monitors Adaptec RAID hardware storage controller metrics about both physical and logical drives.

It uses the arcconf command line utility (from adaptec) to monitor your raid controller.

Executed commands:

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

This collector is supported on all platforms.

This collector only supports collecting metrics from a single instance of this integration.

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.

Default Behavior

Auto-Detection

After all the permissions are satisfied, netdata should be to execute commands via the arcconf command line utility

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.

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 AdaptecRAID instance

These metrics refer to the entire monitored application.

This scope has no labels.

Metrics:

Metric	Dimensions	Unit
adaptec_raid.ld_status	a dimension per logical device	bool
adaptec_raid.pd_state	a dimension per physical device	bool
adaptec_raid.smart_warnings	a dimension per physical device	count
adaptec_raid.temperature	a dimension per physical device	celsius

Alerts

The following alerts are available:

Alert name	On metric	Description
adaptec_raid_ld_status	adaptec_raid.ld_status	logical device status is failed or degraded
adaptec_raid_pd_state	adaptec_raid.pd_state	physical device state is not online

Setup

Prerequisites

Grant permissions for netdata, to run arcconf as sudoer

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 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

Configuration

File

The configuration file name for this integration is python.d/adaptec_raid.conf.

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 python.d/adaptec_raid.conf

Options

There are 2 sections:

• Global variables
• One or more JOBS that can define multiple different instances to monitor.

The following options can be defined globally: priority, penalty, autodetection_retry, update_every, but can also be defined per JOB to override the global values.

Additionally, the following collapsed table contains all the options that can be configured inside a JOB definition.

Every configuration JOB starts with a job_name value which will appear in the dashboard, unless a name parameter is specified.

Config options

Name	Description	Default	Required
update_every	Sets the default data collection frequency.	5	no
priority	Controls the order of charts at the netdata dashboard.	60000	no
autodetection_retry	Sets the job re-check interval in seconds.	0	no
penalty	Indicates whether to apply penalty to update_every in case of failures.	yes	no

Examples

Basic

A basic example configuration per job

job_name:
    name: my_job_name           
    update_every: 1         # the JOB's data collection frequency
    priority: 60000         # the JOB's order on the dashboard
    penalty: yes            # the JOB's penalty
    autodetection_retry: 0  # the JOB's re-check interval in seconds

Troubleshooting

Debug Mode

To troubleshoot issues with the adaptec_raid collector, run the python.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.d directory, usually at /usr/libexec/netdata/plugins.d/. If that's not the case on your system, open netdata.conf and look for the plugins setting under [directories].

  cd /usr/libexec/netdata/plugins.d/

• Switch to the netdata user.

  sudo -u netdata -s

• Run the python.d.plugin to debug the collector:

  ./python.d.plugin adaptec_raid debug trace
