Hi all, i have a set of sensors deployed to a switch to report ping, uptime, cpu and traffic over SNMP Ping reports as i'd hope constantly stable for 10 days but all the other sensors are dropping out every half hour for around 15 minutes.

What could be causing this flapping of states ?

Hey samuelma,

Thank you for your KB-post.

  • Please open a ticket (using ticket # PAE829693) and forward us screenshots of one of the affected sensors (tabs: "Overview", "Log" and "Settings") and from the parent device (tab: "Settings").
  • Please use our SNMP Tester, run it on the PRTG Host (or host of the Remote Probe), and perform a "Scan available standard interfaces" against the target device. Which results do you get in the Tester? Please send us the result logfile from the Tester.
  • Which version of PRTG are you currently running?

Best regards,
Sven

Hi Sven,

Thank your for your assistance, with the help of my networks team we have deduced this problem is being caused by an IP conflict within the network for the probe group. Reassigning IPs solved this problem.

As a side note, i know SNMP isnt a fantastic protocol but if you guys could implement some kinda better error system for SNMP checks, troubleshooting a generic "No Response" is very tricky.

Your support is great though.

Thanks Samuel
