Monitoring an EMC Celerra

[olourkin-nagios at yahoo.com]

Thanks for the info James, appreciate your taking a stab at it.  I did come 
across that site, but I haven't yet dug into everything it presents.  Could be 
some good info there.  I'll start messing around, and if I make any headway I'll 
share it with you and the list.

Cheers,
Erik

Thanks, that helps understand better. Unfortunately, the celerra
datamovers run DART OS, an EMC-propietary os, so i'm not sure what kind
of visibility you may have into the datamovers from the CS via snmp... i
imagine little if any, without use of other binaries/helpers..  

I did find this, which is new to me as well... apologies if you have
been there and are looking for snmp-only..

EMC seems to like making simple things very complex - I'm the guy who
runs the celerra and the nagios setup, and in the past 3 years not one
part/things has failed on the celerra, so I tend to not worry as much
about them - especially if you have a standby-datamover in your
celerra(s).

let us know how things go, sorry i cannot be of more help, but i am
always interested in all things nagios & SNMP,... & EMC.

cheers,
james

Well, assuming we can get snmpd set up to allow gets despite EMC's
claim, we'd be attempting to monitor the celerra's datamover via the CS.
As far as I understand, snmpd runs on the CS, so that's where our
queries would have to go. 
It's still an open question whether we'd be picking up DM data at that
point, or whether we'd only be seeing data for the CS. 

As to what and why I'm looking to monitor this way - I'm in a large
organization with a Nagios implementation that I maintain.  But I don't
maintain the Celerra's.  So I'd much prefer to handle all the check and
threshold definitions within Nagios, rather than having to learn the
Celerra config, and then having to poke the guy who does maintain them
until he gets them set properly.

May not work out that way, but I'm at least going to give it a shot.

Cheers,
Erik

Hi all -

Been digging around to try to figure out how to enable SNMP gets against
an EMC Celerra so that I can implement active checks in Nagios.  I have
traps set up, but I much prefer active checks whenever possible.
Problem is, EMC support says the Celerra isn't capable of allowing gets.

I've heard and suspected otherwise, so I thought I'd check the list to
see if anyone's made the necessary config changes to allow gets.  I
think it should be a matter of changing /etc/snmp/snmpd.conf, but has
anyone tried?

Thanks,

Erik Larkin

I guess having skipped bothering to implement this at our site, i look
at this a different sort of way, and ask - are you attempting to monitor
the celerra 's datamover via the CS (Control station?), or directly
against the dm(s)?

I'm not sure what you wish to monitor either - the celerras have some
pretty good internal alerting configs if you dig around ... at least
they have worked fine for us.

what are you attempting to do specifically , like monitor just health /
temp stuff, or filesystem/share usage etc etc? I'm also curious because
i use SNMP gets here extensively, just never bothered against the
celerra... 


cheers,
James
