CFEngine Enterprise can report on promise outcomes (changes made by
across your infrastructure), variables, classes, and measurements taken by
cf-monitord. Reports cover fine grained policy details, explore all the
options by checking out the custom reports section
of the Enterprise Reporting module.
Specifically which information allowed to be collected by the hub for reporting
is configured by
default_data_select_host() defines the data to be collected for a non policy hub
default_data_select_policy_hub() defines the data that should be collected
for a policy hub.
Controlling which variables and classes should be collected by an Enterprise Hub
is done primarily with a list of regular expressions matching promise meta tags
for either inclusion or
variables that have
meta tags matching
metatags_include and do not have
any meta tags matching
metatags_exclude and does
not have a handle matching
namespace scoped (global)
classes having any meta tags matching
metatags_include that do not have any meta tags
Instead of modifying the list of regular expressions to control collection, we
recommend that you leverage the defaults provided by the MPF (Masterfiles Policy
Framework). The MPF includes
If it's desirable for the classes and variables to be available in specialized
inventory subsystem then it should be tagged with
inventory and given an
attribute_name= tag as described in the custom inventory example.
cf-hub collects information resulting from all other promise types (except
defaults which cf-hub does not collect for). This can be
further restricted by specifying
Collection of measurements taken by
cf-monitord are is controlled using the
There are various limitations with regard to the size of information that is collected into central reporting. Data that is too large to be reported will be truncated and a verbose level log message will be generated by cf-agent. Some noteable limitations are listed below.
- string variables are limited to 1024 bytes
- lists are limited to 1024 bytes of serialized data
- data variables are limited to 1024 bytes of serialized data
- meta tags limited to 1024 bytes of serailized output
- log messages are truncated to 400 bytes
Please note that these limits may be lower in practice due to internal encoding.
Users can not configure the data is stored to disk. For example, you can not
prevent the enterprise agent from logging to
