Dera all, I have a strange message on my vThunder. I’m sending log messages to my syslog server to keep trace of the client connections, locally I log up to warning severity so I expect not overload my buffer, you can see my configuration in the screenshot attached. The problem is that I receive a lot of messages like _“Local log traffic is too heavy. Lost 383 local log messages in last minute.”_ as shown in the second screenshot. I really can’t understand where this local log messages are generated, someone could help me on troubleshooting this?

Thanks

Luca

We recently experienced the same log error message. You can fix this by specifically setting rate limiting for external logging. I suggest watching your real time memory and control CPU. **conf t slb common rate-limit logging max-remote-rate 2000 exclude-destination local** You can then check how many logs you are sending per second based on the following command. **show slb rate-limit-logging** Total ------------------------------------------------------------------ Total log times 336967919 Total log messages 336967423 Local log messages 88452 Remote log messages 336965267 Local rate (per sec) 0 Remote rate (per sec) 931 Log message too big 0 No route 168512250 Buffer alloc fail 0 Buffer send fail 0 Log-session alloc 79 Log-session free 79 Log-session alloc fail 0 No repeat message 7
