'Unknown' Host Status

Hi,

I am having some trouble getting cacti to detect several servers in my organization. I have followed the installation procedure according to the official documentation. When I add a device, the host status shows as 'Unknown' (see screenshot). I can add graphs, but they show up as 'Not Being Graphed'.

Localhost seems to be working and graphing just fine, so at first I thought it was the firewall on the servers. I turned off the firewall but still the same problem.

Any ideas?

Thanks,
Paul

when you click on the device name, does it show any SNMP information under the device name on the next page, or does it say SNMP Error?

Well, I don't see any type of error, but no device information either. The only thing I see for SNMP options is 'SNMP Version', which is 'Not In Use'.

Does each device I want to monitor require some kind of client or agent on it? I installed net-snmp on the two servers shown in the screenshot.

Depending on the "downed host detection"
If you do not use SNMP, you won't see an SNMP error, for sure. But if you did not yet create any graph for that device, it will always be "unknown"

For my part, i would like to just query if my host is down or not.
Therefore I created a device with "SNMP Not in Use" and a Downed Device Detection "Ping".
The status stays being "unknown" and you say if no graph is created, the status will stay to be unknown but it's illogical! Else why create a "ping" Downed Device Detection ???

Am I wrong ? What's the prob ?

Use spine then. Or mess with the Advance Ping template and do a ping graph.

It's ok

Now my host is Up with a TCP Ping port 80.

I have installed the Threshold plugin to have Downed Host Notifications.

First, if my host goes down, Cacti "realizes" it really late (somelike 5/10 minutes). But the bigger problem is that I receive no email, whereas my postfix server is ok. I've realized that there wasn't any "Mail/DNS" groove in the Settings page of Cacti !!!

Has someone ideas ?
