How do you monitor network stats ?

EMC DPA (Data Protection Advisor) - the Celerra license is quite affordable

i have DPA for my Avamar environment, not the most intuitive product i've ever used to be honest with you.  Common Rainer ..tell me how to  query nasdb or whatever it is that Celerra monitor is using to store the data?

Do you run snmpwalk on the control station ? I just tried and it Timed out.

i have no problem graphing the data, how do i capture it other than runing server_stats ?

SNMP MIB-II - even server_netstat uses that to get the info from the data mover :-)

try a snmpwalk -Cc server_2 public  to see whats in there

http://www.oidview.com/mibs/0/RFC1213-MIB.html

Thats not very difficult to figure out

(even though I think the S for simple in SNMP is a misnowner )

2700 entries, wow ..i can't figure out which counters represent network stats.

sorry - syntax changed - see what your community string is set to and then try  snmpwalk -v 1 -c public server_2

yes, I've done it on the control station

[nasadmin@nstest ~]$ snmpwalk -v 1 -c public server_2 | wc -l
644

i'll be honest i have zero, null experience with snmp ...can you help me identify those counters. Nothing jumps out at me.

Thank you

come on :-)  its all in the oidview link - attached is how to dump the interface stats table

I would still recommend the MRTG route since these are only counters - no bytes per second

you would have to compute that for yourself plus deal with the counters overflowing, getting reset, and so on

MRTG already has all that logic builtin

the ifInOctets / ifOutOctets are the same as InBytes / OutBytes in netstat -i

hey ..this was too easy, straight out of the box (Ubuntu 9.04) MRTG started collecting network stats for all interfaces, including management interfaces on each datamover.  I was hoping it would display other stats like datamover CPU load ..etc but this is a good start. Thank you Rainer very much !!!

With gigabit interfaces and 32-bit counters, the counters can wrap in roughly 34 seconds when running at high speeds...100Mbits wrap in 5.7 minutes...  I have never been able to get the 64-bit counters (or snmp v2..) to work with our version of DART - so while you are getting something back, it is likely gibberish unless you never run over 100Mbits.  I monitor the switchports instead as my switch supports the 64bit counters.

Hi dynamox,

you're very welcome!

told you its easier with MRTG :-)

the reason it works out-of-the-box is that this info is the standard MIB-II that every device implements that does SNMP.

I'm afraid there currently isnt much more than network stats that you can currently get via SNMP from the data mover.

I would appreciate if you (and any other customer that wants it) spend a couple of minutes filing a Product Enhancement Request (PER) via Powerlink to get more stats implemented in the data mover SNMP daemon.

a few more the network stats could be interesting, like some of the ip forwarding and error counters

also the number of TCP connections can give you an idea about the number of active clients (CIFS and NFS/TCP)

you could also poll the control station SNMP for some CS info - that one at least includes CS load and memory as well

It also shouldnt be too difficult to gather other stats via server_stats and feed them into MRTG

have fun

Rainer

yeah, i read that you can have a custom script that will feed 4 values to MRTG and it will grapth it.  I might get creative with "server_stat -table dvol" .  Thanks again.
