Hoping I can get some direction. Any posts I'm able to find seem to point to Permissions issues or this problem being a global issue. I'm only having a problem with newly added Meraki MX64 Devices. I'm able to create graphs for other devices (Ex Cisco Switches, Firewalls) I connect to the Meraki MX64 using the Generic SNMP-enabled Host Template. Verbose Query comes back fine no errors. I can see the interfaces and add the In/Out Bits (64-Bit Counter) for graphing them. However after poling cycle the graphs do not created The Debug on the graph just says "ERROR: opening 'C:/inetpub/wwwroot/cacti/rra/corp_meraki_mx64_traffic_in_12827.rrd': No such file or directory"

snmpwalk connects and I can pull the ifHCInOctets/ifHCOutOctets just fine...

Help/suggestions please?

(Edit) Forgot to mention if I use Realtime graphs pluggin it pulls the data for realtime successfully

Bump. Any suggestions? I can't figure out why only these Meraki devices won't pole and create rrd. Yet live graphs work?

[Mrvw67]

Still struggling with this. I don't get why rrd won't create graphs for just the meraki. I'm using the builtin SNMP - Interface templates and it is able to read all 5 just fine. I created graphs using the In/Out Bits (64-bit Counters).
I can confirm I get data with snmpwalk, and realtime graphs work... just rrd never makes a graph during the normal polling. Permissions don't seem to be an issue either as I just created another 8 Cisco Switch devices using Generic SNMP also and those are generating fine.

Ok I've got some additional news. I tried changed the poller from cmd.php to Spine. When the poller was cmd.php the graphs (again only for meraki devices) would not generate a graph. When I changed it to Spine, the graphs generated.

Why would the poller make such a difference?

To test this I spun up a new Cacti Server and added only Meraki devices. You can see with the cmd.php polling it didn't process any RRD's. Yet once I switched to Spine they got processed.

Bump. Any ideas why I can only poll Meraki using Spine and not cmd?

I think the biggest problem is that you are using Windows and not Linux. It also looks like you may have some permission issues, or there are missing components such as net-snmp or php-snmp, you can tell this from Settings > Paths. Or, being that there were 0 data sources updated, it could be that you are playing with settings and turned boost on/off between testing. You have to really know what you are doing before you turn on boost. I suggest you move to Cacti 1.x also. Lastly, if you were using Linux, I could be more helpful.
