Hi! I have an interesting Problem:
I am monitoring some ESXi 4 and some ESXi 5 hosts. The ESXi 4 hosts are free, and the ESXi 5 are in a vSphere Essentials environment. I'm monitoring with the following sensors: esxserverhostsensor, sshdiskfreesensor, diskspacesensor, esxservervmsensor. On the ESXi 4 hosts everything is fine. On the ESXi 5 hosts my root partition is running full (ramdisk). I thought i have a problem with the log files, and moved the scratch to a bigger (persistent) storage. The only file with stayed in the ramdisk under /var/log is wtmp. And this file is growing very fast, as long as i have the sensors running. If i stop the monitoring the file grows very slow. My sensors are set to 30 seconds monitoring interval. I know that this is very short, and i thought to set the disk space sensors to 6h or 12h. But this doesn’t solve the problem, just makes the growth rate slower, and would not help me if i would have a problem with local storage running full on any ESXi host. I just would get the warning some h to late.
Do you have an idea how to fix this without changing the interval to more than a few minutes?
