Troubleshooting: Polling Does Not Complete for My Sensitive Device

Symptom:

I have a critical device that I must monitor, but polling cannot complete in a single polling cycle. Sometimes there is so much network traffic that my device stops working completely. This device is known to be sensitive, but how can I reliably poll this device to help ensure good performance?

Solution:

Polling is vital for monitoring a device. However, too much polling can cause too much network traffic and can degrade your ability to monitor a device successfully. If too much network traffic is overwhelming your sensitive device, you can try the following adjustments to reduce overall traffic to the device:

• Adjust your monitoring profile to remove unnecessary metric families from polling.
• Apply a filter in your monitoring profile to reduce the number of polled interfaces.
• Adjust your monitoring profile to poll less often (for example, change the SNMP Poll Rate to 15 minutes, instead of the default 5 minutes).
• Adjust the SNMP traffic threshold to lower the number of SNMP requests that are sent to the device at a time.
• Adjust the SNMP timeouts threshold to control how many polling timeouts cause polling to suspend for the current polling cycle.
