After upgrading my nodes to 1.34.1, I noticed that the Tip Diff KPI in gLiveView began returning high 200+ results and the block propagation times increased by a couple seconds. The relay nodes are running fine, no change in behavior.

In addition to the node upgrade, I did implement a firewall threat detection and blocking service called "SNORT" on my WAN.

I have attempted to reboot the nodes, but behavior remains.

Node version: 1.34.1 gLiveView version: 1.26

Overall, I feel that the relay and core nodes are operating fine but perhaps the issue is with gLiveView.

NOTE The missed slot leader checks KPI did not change. The value still show "favorable" data after upgrade just as it did before upgrade.

All help / information is very much appreciated.

my 1.34.1 tip diff is showing regular metrics.

  • How did you configure SNORT? Try to stop the service and see if kpi is returning back to normal.

If not

  • Switch back to cardano-node 1.33.0 and see if kpi is returning back to normal.

Hope it helps

  • Thanks for the suggestion. I did temporarily stop the SNORT service, so we will see over the next few days if the KPI values return to normal. Thanks again!

  • In troubleshooting this issue further, it appears that reinstalling gLiveView on all nodes has resolved the issue. I will continue to monitor the core node for a couple days before confirming as solution. NOTE I have restored the SNORT service on the WAN Thanks

This issue has been resolved by reinstalling gLiveView to the latest version. No issues are caused by the SNORT service on my firewall.

Thank you, Nick
