Controller devs We have been facing issues while trying scaled scenarios on bgp and netconf projects when the setup was clustered. We had tried some settings to improve the replication performance like using tell-based mode enabled and then tried to tinker with few other factory/akka.conf settings like akka.cluster.failure.detector.acceptable-heartbeat-pause. These measures improved performance a bit since the tolerance for heartbeat detection failure was increased.
We also enabled the artery mode to and did the corresponding setting changes in akka.conf to enable it. After some other setting changes, we could avoid the OOM issues that we faced initially. But inspite of these, we were not able to successfully run the cluster on artery mode. We may be able to troubleshoot it further if we are able to find some more detailed logs from akka. Are there any 1. Log settings we can enable to get the debug/trace level logs from akka ? 2. Any other akka settings which we can tune to choose an acceptable tradeoff ? We have been using master for these tests to bring in the patches to improve cluster performance (mainly from TomP and Robert). -- Thanks Atul
