Error description
The Linux OS Agent by default monitors all filesystem types. There are options only to exclude NFS and CIFS types. It does not provide any options to filter out other specific types. In servers configurations where there is a huge number of filesystems the Disk data collection may become extremely slow, and it would be useful to filter out the filesystem types that are not needed. Affected Platforms / Versions: This issue affects all the Linux OS agent versions and it does not depend on the Linux OS version. Initial Impact: Medium, unneeded monitoring of filesystems can introduce performance issues on the server where the agent runs. Additional Keywords: FileStats KLZDISK Linux Disk File System Type FSTYPE

Problem summary
Problem Description: Performance impacts due to missing option for excluding unneeded filesystem types on Linux Problem/Problem Summary: The Monitoring Agent for Linux OS only provides the possibility to choose whether or not NFS and CIFS filesystems must be monitored. Any other types cannot be excluded. In case of a large number of filesystems of the same type that don't need to be monitored, this limitation can introduce performance issues on the agent. In order for this APAR to be properly implemented in your environment, a new environment variable has been added. See the "Install Actions" section of the APAR conclusion for more details.
Problem conclusion
Problem conclusion: Introduced new environment variable that allows to exclude a list of filesystem types. Install Actions: set KLZ_EXCLUDE_FSTYPE=<comma separated list of types> in the lz.ini configuration file. Example: KLZ_EXCLUDE_FSTYPE=mvfs,ext3. The The names must match exactly those shown by command "mount -l". In case of conflict with KBB_SHOW_NFS or KBB_SHOW_CIFS settings, KLZ_EXCLUDE_FSTYPE takes priority. The fix for this APAR will be contained in the following maintenance packages: | FixPack | 6.3.0-TIV-ITM-FP0007 | InterimFix | 6.3.0.6-TIV-ITM_LINUX-IF0004
