If your hostd, vpxd and or vpxa log files are rotating to quickly or not quick enough check out this great KB article on how to set this up. The most important thing to set is the maximum amount of logfiles and the size. Be sure to do a basic calculation so your logging partition won’t fill up completely! And while your at it, might be worth setting up the rotation scheme for vmkernel, messages etc. If I can find the time I will do a blog article on that one later this week.
