Disable SNMP polling

[rdilallo]

Okay, here's a crazy question...

I want to use Cacti to monitor Microsoft devices WITHOUT having SNMP enabled. Can it be done? I've seen issues where the poller will not collect the data from my WMI queries because it first wants to check the device with SNMP.

Any takers?

Change the polling downtime method to Ping only. Then your WMI query scripts should work fine.

That's fine, however, when you first add a device, it checks SNMP. This will cause the device to show a status of "down". How do I get around that?

[BSOD2600]

After first adding it, the status should be UNKNOWN. Can you truly ping your host from the cacti computer fine?

[rdilallo]

I can still ping them. I can also run a perl script against one of the devices to gather WMI information. It seems that when the poller runs, my RRD's don't update. Looking at the poller log, it's because I can't communicate via SNMP. Ugh...

Something interesting...
So, I started over with the site. I removed locahost. I went to settings and configured my site to use ping only (no snmp). I added back localhost and a remote server. Localhost shows "SNMP not in use", while the remote server says "SNMP error." What's that about?

[BSOD2600]

The SNMP error has to do with cacti trying to query the device for some basic SNMP info. It's related to this thread. If cacti polls the device with your scripts fine, then you can ignore the snmp error.

This is default behavir, if you clear the read string (hokey workaround), Cacti will ignore the SNMP string and it will instead say "SNMP Not In Use".
