Hardware
cisco Nexus9000 C9508 (8 Slot) Chassis ("Supervisor Module")
Here is the steps to reproduce the issue with the SNMP packets,
- Use the Cisco IOS by SNMP template to monitor a Cisco Nexus 9000 device.
- Observe that the SNMP packet count on the device is 100 packets per minute.
- Use the Cisco Nexus 9000 Series by SNMP template to monitor a Cisco Nexus 9000 device.
- Observe that the SNMP packet count on the device is also 100 packets per minute.
- Disable monitoring for the devices in Zabbix.
- Observe that the SNMP packet count on the devices goes back to normal.
The issue is that Zabbix is sending too many SNMP packets to the devices. This is causing the devices to become overloaded.
In Zabbix 4.0, the SNMP packet count for the Cisco IOS by SNMP template is around 10 packets per minute (same nexus 9000 device). This is a more reasonable number, and it does not cause the devices to become overloaded.
The following are some possible solutions to the issue:
- Upgrade SNMP template that sends fewer packets.
- Configure Zabbix to poll the devices less frequently.
We are not sure why Zabbix is sending so many SNMP datagrams to the Nexus 9000 device.
