List files and dirs under /var/lib/nova/instances
The parsers class in this module uses base parser class
CommandParser
& FileListing
to list files & directories.
Parsers included in this modules are:
LsRVarLibNovaInstances - command ls -laR /var/lib/nova/instances
LsVarLibNovaInstances - command ls -laRZ /var/lib/nova/instances
- class insights.parsers.ls_var_lib_nova_instances.LsRVarLibNovaInstances(*args, **kwargs)[source]
Bases:
CommandParser
,FileListing
Warning
This class is deprecated and will be removed from 3.5.0. Please use the
insights.parsers.ls.LSlanR
instead.The class
LsVarLibNovaInstances
don’t show file size when the flag -Z is used. This class parses the output ofls -laR /var/lib/nova/instances
to output file listing with file size.Note: This issue is not seen in GNU coreutils-8.29. When the coreutils package is updated to 8.29 on RHEL7, this parser class can be deprecated.
Typical output of the
ls -laR /var/lib/nova/instances
command is:/var/lib/nova/instances: total 4 drwxr-xr-x. 5 nova nova 97 Feb 20 2017 . drwxr-xr-x. 9 nova nova 111 Feb 17 2017 .. drwxr-xr-x. 2 nova nova 54 Feb 17 2017 _base -rw-r--r--. 1 nova nova 44 May 26 2017 compute_nodes drwxr-xr-x. 2 nova nova 54 Feb 17 2017 e560e649-41fd-46a2-a3d2-5f4750ba2bb4 drwxr-xr-x. 2 nova nova 93 Feb 17 2017 locks /var/lib/nova/instances/_base: total 18176 drwxr-xr-x. 2 nova nova 54 Feb 17 2017 . drwxr-xr-x. 5 nova nova 97 Feb 20 2017 .. -rw-r--r--. 1 qemu qemu 41126400 May 26 2017 faf1184c098da91e90290a920b8fab1ee6e1d4c4 /var/lib/nova/instances/e560e649-41fd-46a2-a3d2-5f4750ba2bb4: total 2104 drwxr-xr-x. 2 nova nova 54 Feb 17 2017 . drwxr-xr-x. 5 nova nova 97 Feb 20 2017 .. -rw-r--r--. 1 qemu qemu 48957 Feb 20 2017 console.log -rw-r--r--. 1 qemu qemu 2097152 Feb 20 2017 disk -rw-r--r--. 1 nova nova 79 Feb 17 2017 disk.info /var/lib/nova/instances/locks: total 0 drwxr-xr-x. 2 nova nova 93 Feb 17 2017 . drwxr-xr-x. 5 nova nova 97 Feb 20 2017 .. -rw-r--r--. 1 nova nova 0 Feb 17 2017 nova-faf1184c098da91e90290a920b8fab1ee6e1d4c4 -rw-r--r--. 1 nova nova 0 Feb 17 2017 nova-storage-registry-lock

Warning
This class is deprecated and will be removed from 3.5.0. Please use the
insights.parsers.ls.LSlanRZ
instead.Parses the output of
ls -laRZ /var/lib/nova/instances
command which provides the SELinux directory listings of the ‘/var/lib/nova/instances’ directory.The
ls -laRZ /var/lib/nova/instances
command provides information for the SELinux directory listing of the/var/lib/nova/instances
directory.Typical output of the
