Since it's a new program, it won't destabilize any existing code,
which to me is the prime definition for something "stable".

While we're on the subject of netapps, let's talk about who's polling
what.  My shop's mon.m4 runs several tests against our NetApps:

  ping
  rpc.monitor
  netappfree.monitor
  netappraidstat.monitor
  snmpvar.monitor - tests these vars:

Variable NETAPP_FAILED_FAN_COUNT
    OID .1.3.6.1.4.1.789.1.2.4.2.0
    Description Number of Netapp Failed Fans is
    
Variable NETAPP_FAILED_POWER_SUPPLY_COUNT
    OID .1.3.6.1.4.1.789.1.2.4.4.0
    Description Number of Netapp Failed Power Supplies is

Variable NETAPP_TEMPERATURE_WARNING
    OID .1.3.6.1.4.1.789.1.2.4.1.0
    Description Netapp Temperature Warning
    Decode 1    no
    Decode 2    yes

Variable NETAPP_RAID_SPARES
    OID .1.3.6.1.4.1.789.1.6.4.8.0
    Description Number of Available Spare Disks is


1) Did we ever check in all of Todd's fixes to  netappraidstat.monitor?  I
have a version he emailed me on 21 Dec 2005 after we got it working on
with the elderly NetApps at my site.

2) Augie, reading over your new script, it looks like we could do
the same thing by using snmpvar.monitor on
NETWORK-APPLIANCE-MIB::diskFailedCount with an entry like this in
snmpvar.def:

Variable NETAPP_DISKS_FAILED
    OID .1.3.6.1.4.1.789.1.6.4.7.0
    Description Number of Failed Disks is

It would be nice if we could roll all this stuff up and make up a NetApp
"howto" page for Mon.  I would volunteer, except as mentioned above the
NetApps I have access to are rather ancient, and we're phasing them out...
