file_dirs_names_service_plugin

[Tomasz Trębski]

Info:

Cannot configure ServicePlugin to watch file in directory

Reproduce:

Download master branch of monasca-agent
Execute: monasca-setup -d keystone -a "file_dirs_names=[('/var/log/apache2',['keystone.log','keystone_access.log'])]"

Expected:

Plugin successfully created monitoring aforementioned files

Observed:

(monasca-agent) root@devstack:/home/vagrant/devstack# monasca-setup -d keystone -a "file_dirs_names=[('/var/log/apache2',['keystone.log','keystone_access.log'])]"

IndexError: string index out of range

It looks like iteration over file_dirs_names expects that argument will be parsed into an array, however it is still a string at this point therefore iteration goes by each character in this string.

For file_size and directory check, monasca-setup command line is not support it. Because depends on the files, the directory and file name combination can be very long. Right now, you can create your own customer defined detection plugin based on the template: https://github.com/openstack/monasca-agent/blob/master/monasca_setup/detection/plugins/file_size.py to run file_size check.
