SNMP HOST-RESOURCES-MIB: Used Space in Filesystems
Distribution offizieller Teil von Check_MK
Lizenz GPL
Unterstützte Agenten SNMP

This check monitors the usage of filesystems using SNMP and the {HOST-RESOURCES-MIB}, which is supported by many SNMP agents - especially those on full operating systems. For configuration parameters and examples please refer to the man page of {df}. Please note, that due to the fact that Linux usually reserves 5% of the filesystem for root, the amount of used space output by this check and the native {df} check of Linux differs by up to 5%. The {df} check accounts the reserved space as used, as this is a safer assumption. Whereas the SNMP agent accounts it as free. There is no way to get the information about the reserved space via SNMP, so there is no way to fix this, unfortunately.

Item

The description of the filesystem as in {hrStorageDescr}. For Linux SNMP agents this is the mount point.

Discovery

One service is created for each fixed disk if the description of the filesystem in not listed in {inventory_df_exclude_mountpoints}.
