在被监控的主机snmpd.conf中加入如下内容
…. ############################################################################### # disk checks # # The agent can check the amount of available disk space, and make # sure it is above a set limit. # disk PATH [MIN=DEFDISKMINIMUMSPACE] # # PATH: mount path to the disk in question. # MIN: Disks with space below this value will have the Mib‘s errorFlag set. # Default value = DEFDISKMINIMUMSPACE. # Check the / partition and make sure it contains at least 10 megs. #disk / 10000 #disk / 100000 includeAllDisks 10% ….
主要是includeAllDisks 10%这句，如果没有这句话，出问题的磁盘空间实际上显示的是cacti所在主机的磁盘空间。
至于为什么，不是很明白。
