No data collected and not logs

[markfree]

Recently I found an odd issue with some monitored hosts.

I have a host that started being monitored by a Proxy using SNMP. Zabbix 6.2 shows it as available and is collecting most data from it.


I can see most data being collected correctly, but some items have no data yet.


When I test the items, Zabbix shows the correct value for it.


I can also get data using snmpget.

$ snmpwalk -v 2c -c [community] 10.105.51.237 1.3.6.1.4.1.674.10892.5.1.3.12
SNMPv2-SMI::enterprises.674.10892.5.1.3.12.0 = STRING: "PowerEdge R620"​

Still, Zabbix won't write any data for this item.
Also, the proxy logs don't show any lines for this host or item.

Any ideas?

Here comes packet capture suggestion again... You have the "Discard unchanged with heartbeat" step configured, with what interval? If you want to be sure if the data is being polled or not, it's easy to run sudo tcpdump host <ip-of-the-host> and port 161 -w snmp.pcap -v and then check it with Wireshark if you see the expected OIDs being fetched or not.

Latest data page only shows a limited amount of time, was it 24 hours.

Only now have I been able to return to this topic.
I actually did not do anything, but now the data is being collected.
Let it be...
