Hi all,

I'm currently working on getting our PRTG instance to report on Meraki devices via API, but at this time PRTG only works with numbers, not text fields. As such, I'm trying to at least get SNMP setup.

I have access to two organizations, one has about 50 devices in, one has almost 800. When I setup PRTG to find the devices using the OID 1.3.6.1.4.1.29671.1.1.4, for the org with 50 devices, it brings up the custom table, when I do it on the org with 800 devices, it always times out. The only difference I can see is the amount of devices. Is there something about trying to poll lots of devices that just doesn't work? I'm trying to work out if this is an issue Meraki side or PRTG side. I've tried increasing the timeout, but 10 seconds is fine for the 50 org, 30 seconds still fails on the 800 org.

Hello,

Thanks for contacting us.

Do you see any particular error when you see the timeout from the org that has 800 devices? Please send me the error in clear text if possible.

Did you also try the API for Meraki sensors?

Hi Miguel,

The error is:

Could not create the sensor SNMP Custom Table on device Meraki Cloud (snmp.meraki.com).

No response (check: firewalls, routing, snmp settings of device, IPs, SNMP version, community, passwords etc) (SNMP error # -2003)

I know all the settings are correct, if I change only the community string to that of my 50 device network and run the same sensor creating with the same OID it'll work, and both Meraki orgs are setup identically for SNMP settings.

Also, I get this error when creating the sensor in PRTG, but when I walk the OID with your SNMP tester, it walks, it takes a long time to return all the data, and it does it in chunks, but it works.

SNMP timeouts?
