I noticed today while looking at the request.log file something a little different. This is a multi-cell environment and I wanted to verify how traffic is hitting the cells. Typically I have been able to just login and go straight to the logs directory and tail the request.log file. Today I noticed that cell01 the log files were only present for today, and that they were appended by numbers (2013_06_27.request.log.024221650). The other cell had the most recent request.log file as simply request.log without the numbers, and older logs with the appended numbers. The issue I have with this is that it seems like there is no recent request.log on cell01 because the most recent log is 3 hours ago.

Thanks in advance
I'm sure you've already figured this out by now.
You just happen to have traffic load balancing to one cell for some time. that's about it really. An these are mostly for API call logging, or website logins (getting the HTTPS session started). If the log rotates, then we stamp the files and use them as the roll over.
I ended up rebooting cell01 because there was no way of seeing the log, so after it came back from reboot the logs were populated correctly and I was able to view the log on both cells. From there I could also tell that the load balancer was now balancing to both cells correctly.
