+# Simple parser for /proc/mdstat that outputs status of all |
| 20 |
+# or some RAID devices. Possible results are OK and CRITICAL. |
| 21 |
+# It could eventually be extended to output WARNING result in |
| 22 |
+# case the array is being rebuilt or if there are still some |
| 23 |
+# spares remaining, but for now leave it as it is. |
| 24 |
+# |
| 25 |
+# To run the script remotely via SNMP daemon (net-snmp) add the |
| 26 |
+# following line to /etc/snmpd.conf: |
| 27 |
+# |
| 28 |
+# extend raid-md0 /root/parse-mdstat.pl --device=md0 |
| 29 |
+# |
| 30 |
+# The script result will be available e.g. with command: |
| 31 |
+# |
| 32 |
+# snmpwalk -v2c -c public localhost .1.3.6.1.4.1.8072.1.3.2 |
