 Description   

When running a SNMP based discovery on the network, scanning each host for a response is very, very slow. I suspect the normal timeout value from the server config file is being used.

As this setting is set to 10 seconds, it'll could take about 2550 second to scan a /24 network for a single SNMP check.
As we are trying to scan /16 network blocks, we are having quite an issue as it will take roughtly 180 hours complete a single scan.

If we were able to configure the timeout (preferably in ms) on the discovery rule, we could lower the amount of time it takes.

I absolutely support that. I recall related discussions in the past.

For network discovery it should be indeed separated from regular checks. Preferably on a discovery check level, or maybe on discovery rule would be enough.

Timeout consideration being changed in different versions as bug fixes or as new features, for example ZBX-4393, ZBX-7719.
So be careful when you use different versions.

Just a note - current feature request has been mentioned in ZBXNEXT-1096.

As mentioned by kodai, it would also be nice to configure the number of SNMP retries for network discovery, similar to ZBXNEXT-1096 for regular polling.
