Slow Proxies ?

[seymourp]

Hi,

I am new to Zabbix and trying 6.4.3 with proxies for SNMP monitoring.

On the server I set a discovery rule and after about 10 minutes this showed in the proxy logs:-

1172977:20230609:103930.767 Received [{"data":{"drules":{"fields":["druleid","name","iprange","delay"],"data":[[21,"Testing VPC1 Proxy","100.64.4.10","1h"],[23,"Testing VPC1 Proxy SNMP","172.31.16.70,172.31.32.70","1h"]]},"dchecks":{"fields":["dcheckid","druleid","type","key_","snmp_community","ports","snmpv3_securityname","snmpv3_securitylevel","snmpv3_authpassphrase","snmpv3_privpassphrase","uniq","snmpv3_authprotocol","snmpv3_privprotocol","snmpv3_contextname","host_source","name_source"],"data":[[21,21,12,"","","0","",0,"","",0,0,0,"",1,1],[23,23,11,"1.3.6.1.2.1","public","161","",0,"","",0,0,0,"",2,2]]}},"config_revision":9502}] from server

Then 21 minutes later the inserts get added to the DB (Sqlite):-

1172987:20230609:110023.851 query [txnlev:1] [insert into proxy_dhistory (clock,druleid,dcheckid,ip,dns,port,value,status) values (1686308423,23,23,'172.31.16.70','',161,'',1)]
1172987:20230609:110023.852 query [txnlev:1] [insert into proxy_dhistory (clock,druleid,ip,dns,status) values (1686308423,23,'172.31.16.70','',1)]
1172987:20230609:110023.854 query [txnlev:1] [insert into proxy_dhistory (clock,druleid,dcheckid,ip,dns,port,value,status) values (1686308423,23,23,'172.31.32.70','',161,'',1)]
1172987:20230609:110023.854 query [txnlev:1] [insert into proxy_dhistory (clock,druleid,ip,dns,status) values (1686308423,23,'172.31.32.70','',1)]

But as it stands some 20 minutes later there is no discover attempted to the devices, either that I can see via the logs or `tcpdump`.

Am I being impatient, is there something wrong, or is there something I can tune ?

Many thanks.
