Collect metrics from the StorCLI utility on the health of MegaRAID
hardware RAID controllers and write them to stdout so that they can be
used by the textfile collector.
We parse the JSON output that StorCLI provides.
Script must be run as root or with appropriate capabilities for storcli
to access the RAID card.
Designed to run under Python 2.7, using the system Python provided with
many Linux distributions.
The metrics look like this:
mbostock@host:~$ sudo ./storcli.py
megaraid_status_code 0
megaraid_controllers_count 1
megaraid_emergency_hot_spare{controller="0"} 1
megaraid_scheduled_patrol_read{controller="0"} 1
megaraid_virtual_drives{controller="0"} 1
megaraid_drive_groups{controller="0"} 1
megaraid_virtual_drives_optimal{controller="0"} 1
megaraid_degraded{controller="0"} 0
megaraid_battery_backup_healthy{controller="0"} 1
megaraid_ports{controller="0"} 8
megaraid_failed{controller="0"} 0
megaraid_drive_groups_optimal{controller="0"} 1
megaraid_healthy{controller="0"} 1
megaraid_physical_drives{controller="0"} 24
megaraid_controller_info{controller="0", model="AVAGOMegaRAIDSASPCIExpressROMB"} 1

Add a utility to parse the output of `smartctl`.
* Scans all disks.
* Prints metrics for `smartctl --info`.
* Prints metrics for `smartctl --attributes`.
