How to register Pingable hosts in discovery

[MARUBUN SUPPORT]

Hi Team,
We have received the following question from one of our customers. 
We would appreciate any advice you can give us.

[Product]
CA Spectrum 23.x
RHEL

[Questions]
The user's system has a node that is not responding to SNMP but wants to register as Pingable.

Because of the large number of nodes in the user's system, the user wants to complete the registration in the shortest possible time and is considering using a discovery rule.
However, the user is aware that even if the "Use ICMP first, then SNMP" option is specified when registering a node using a discovery rule, it will still check for SNMP responses and wait until it times out.
If we want to minimize this waiting time, please let us know what we can do.

Also, users think that if they can perform discovery without specifying SNMP community strings (for v1 and v2c) or SNMP port numbers, the SNMP wait time will be eliminated.
However, they have not been able to confirm that it is possible to run discovery without setting SNMP community strings or port numbers.
Please let me know about this as well.

Best Regards,
Marubun Support

Marubun,

You must supply at least one snmp community string in your discovery configuration. If not, you get the following error when trying to run it.

What you can do is click the Advanced Options button and set the Timeout (In seconds) and Try Count parameters to 1.
