collectors FilestatCollector

FilestatCollector

Uses lsof to collect data on number of open files per user per type

Config Options

• user_include - This is list of users to collect data for. If this is left empty, its a wildcard to collector for all users (default = None)
• user_exclude - This is a list of users to exclude from collecting data. If this is left empty, no specific users will be excluded (default = None)
• group_include - This is a list of groups to include in data collection. If this DOES NOT override user_exclude. (default = None)
• group_exclude - This is a list of groups to exclude from collecting data. It DOES NOT override user_include. (default = None)
• uid_min - This creates a floor for the user's uid. This means that it WILL NOT collect data for any user with a uid LOWER than the specified minimum, unless the user is told to be included by user_include (default = None)
• uid_max - This creates a ceiling for the user's uid. This means that it WILL NOT collect data for any user with a uid HIGHER than the specified maximum, unless the user is told to be included by user_include (default = None)

*** Priority Explaination *** This is an explainatino of the priority in which users, groups, and uid, are evaluated. EXLCUDE ALWAYS OVERRULES INCLUDE within the same level (ie within users or group)

• user_include/exclude (top level/priority)

  • group_include/exclude (second level: if user not in user_include/exclude, groups takes affect)
    • uid_min/max (third level: if user not met above qualifications, uids take affect)

• type_include - This is a list of file types to collect ('REG', 'DIR", 'FIFO' , etc). If left empty, will collect for all file types. (Note: it suggested to not leave type_include empty, as it would add significant load to your graphite box(es) (default = None)

• type_exclude - This is a list of tile types to exlude from being collected for. If left empty, no file types will be excluded. (default = None)

• collect_user_data - This enables or disables the collection of user specific file handles. (default = False)
