Hi @bud4,

Can you try decreasing snmptimeout to 1 and snmpretry to 0 in your agent configuration file ?

Regards,
Léa

Hi @Lea9250 ,
Already tried what you suggested, There was no substantial change. I think the problem lies in the fact that the program continues to query the same IP address with all the oids configured, even if the first query goes into a timeout error

If the subnet range is very large, a long time can pass between the scan carried out by nmap and the subsequent snmp query. This means that in many cases the host is no longer turned on and therefore reachable. Despite multiple tests acting on both the ocs and operating system configurations, I was unable to lower the timeout time to a reasonable value. I think it depends on the perl module.
I would also suggest doing the snmp query in multiple threads.
