Collectd SmartRAID

Collect SmartRAID disk state using ssacli utility

Usage

Default Path for storcli utility is /opt/smartstorageadmin/ssacli/bin/ssacli

To test the data extraction, the python script collector can be run.

It will output the metrics computed for collected and more detailled info about the disks

python -m collectd_megaraid.collector

Configuration

To use with collectd you need collectd-python plugins

LoadPlugin python
<Plugin python>
    # Path where python module is located (if cloned, working copy path)
    ModulePath "/opt/collectd/collectd-smartraid"
    LogTraces true
    Interactive false
    Import "collectd_smartraid.collectd_plugin"
   <Module "smartraid">
     Verbose True
   </Module>
</Plugin>

Metrics Description

The plugin will output 2 metrics

• logical_drive_state with plugin instance = c{controller_slot_id}_d{logical_drive_id}
• physical_drive_state with plugin instance = c{controller_slot}d{logical_drive}{disk_ref}

The value of the metric is the logical state (1=OK, 0=Anything else)

Prometheus export will look like this :
