To choices - use SNMP or use NetApp APIs with their SDK SNMP is simple, but limited - some data seems not to be available through SNMP for CDOT (Cache Age, CIFS ops, NFS ops). Additionally, CPU load is only for one node and possibly for one core - never had time to find out which. SNMP templates can...

So no one has any idea how to deal with this? Anyone? Bueller?

I've been trying for a while to make older NetApp templates to work with current versions of OnTap (see http://forums.cacti.net/viewtopic.php?f=12&t=55805) Was able to make both volume and qtree usage work, but run into very strange problem: when i setup user quotas on homedirs, all qtrees stop ...

Strange. Minor version upgrade like that shouldn't really break things. You can try to compare NetApp MIB files from 2 versions.

What's not working? All qtree graphs? What about volumes graphs?

@stormonts - that "SNMP - Interface Statistics" is not netapp specific: it's the same one that pulls switch interface stats. I guess netapp changed what OIDs return interface stats in CDOT, so netapp specific xml is needed. honestly though - i always monitor switch ports for interface stat...

OK, i think i got it this time. First - there are 3 CDEFs involved, so create them first (i included 2 grap templates - one with and one without dependencies): 1. "_b as percentage of a" (cdef=b,a,/,100,*) 2. "_Make Current Data Source 0" (cdef=CURRENT_DATA_SOURCE,0,*) 3. "_...

Yeah, i'm having no luck either. I'm gonna step back for a while and come back to the problem later.

I just noticed - if i enable user quotas on a qtree, all qtrees stop graphing. don't know why.

CURRENT_DATA_SOURCE,ALL_DATA_SOURCES_NODUPS,/,100,* is given as example in the docs for "disk used" and "disk available" and NetApp only gives "disk used" and "disk total" (as qrV264KBytesUsed and qrV264KBytesLimit), so you're still getting wrong data: (used) ...

In my environment i just monitor space in KB/MB, etc. I use thold cacti plugin and set warning limits on vol/qtree usage. Granted this does not scale well, but works for me. You can play with cacti CDEFs to create graph template for usage in percent: they actually give it as example "Example 19...

define "connecting"? to test if snmp answers on the IP address you're using (i'm assuming cluster management) run from the server cacti is installed on (assuming linux here): snmpwalk -On -c <your_read_only_snmp_community> -v 2c <your_cluster_man_IP> - there should be answer, including CDO...

Don't have any 8.1 CDOT, so can't help you there. For 8.2, yes, you can enable/disable SNMP only per cluster, but if i remember correctly it enables access to nodes using SNMP as well. It's possible networking on individual nodes is not configured with default gateway? Try snmpwalk from machine on t...

No, sorry - just took a quick look at NetApp MIB: no usage in percent. But you can create a graph template using KB and some arithmetic - just don't ask me how to do it. :-P If you want to just monitor volumes and q-trees - use cluster management interface (make sure SNMP is enabled). However - thes...

Attached are following files inside cacti_templates_netapp-64bit-cdot.tar.gz: - netapp_interfaces.xml (drop it in cacti/resource/snmp_queries, you may already have this one there is you setup netapp in cacti before) - netapp-volumes.xml (drop it in cacti/resource/snmp_queries, you may already have t...
