* textfile smartmon.sh Added functions to also parse megaraid disks. Added parsing to also detect the grown_defects counters. * textfile storcli.py Reworked the example file to export lots more information about megaraid attached controllers, VDs and PDs.

"""
|
|
Script to parse StorCLI's JSON output and expose
|
|
MegaRAID health as Prometheus metrics.
|
|
|
|
Tested against StorCLI 'Ver 1.14.12 Nov 25, 2014'.
|
|
|
|
StorCLI reference manual:
|
|
http://docs.avagotech.com/docs/12352476
|
|
|
|
Advanced Software Options (ASO) not exposed as metrics currently.
|
|
|
|
JSON key abbreviations used by StorCLI are documented in the standard command
|
|
output, i.e. when you omit the trailing 'J' from the command.
