Custom Datasources Catalog

insights.specs.datasources

Custom datasources provide functionality beyond simple_file and simple_command type datasources. If the custom datasource is short and concise it may be added to this module. Other datasources should be added as a separate module. Normally custom datasources are necessary for core-collection. In order for a custom datasource to execute, all of its dependencies must be explicitly loaded by the client. The client uses the YAML template insights.collect.default_manifest and each parser/combiner/component required by a custom datasource must be included in the YAML template to ensure it is loaded.

insights.specs.datasources.DEFAULT_SHELL_TIMEOUT = 10

Default timeout in seconds for ctx.shell_out() commands, must be provided as an arg

Type

int

  • commands (list) -- List of commands to search for in ps output

Returns

insights.specs.datasources.package_provides

Custom datasource for package_provides

insights.specs.datasources.package_provides.cmd_and_pkg(broker)

Collect a list of running commands and the associated RPM package providing those commands. The commands are based on filters so rules must add the desired commands as filters to enable collection. If a command is not provided by an RPM then it will not be included in the output.

In order for the full command line to be present in the Ps combiner a filter must be added to the spec ps_auxww. A filter must also be added to package_provides_command so this datasource will look for the command in Ps.

Parameters

broker -- the broker object for the current session

Returns

Returns the collected information as a file with 1 line per command

Return type

DatasourceProvider

Raises

SkipComponent -- Raised if no data is collected

insights.specs.datasources.package_provides.get_package(ctx, file_path)[source]

Get the RPM package that owns the specified filename with path

Parameters

  • ctx -- The current execution context

  • file_path (str) -- The full path and filename for RPM query

Returns

The name of the RPM package that provides the file or None if file is not associated with an RPM.

Return type

str

insights.specs.datasources.ps

Custom datasources for ps information

class insights.specs.datasources.ps.LocalSpecs[source]

Bases: insights.specs.Specs

Local specs used only by ps datasources

ps_eo_args = <insights.core.spec_factory.simple_command object>

Returns ps output including pid and full args

registry = {}
insights.specs.datasources.ps.ps_eo_cmd(broker)

Custom datasource to collect the full paths to all running commands on the system provided by the ps -eo pid,args command. After collecting the data, all of the args are trimmed to leave only the command including full path.

Sample output from the ps -eo pid, args command:

PID COMMAND
  1 /usr/lib/systemd/systemd --switched-root --system --deserialize 31
  2 [kthreadd]

  9 [mm_percpu_wq]
 10 [rcu_tasks_kthre]
 11 /usr/bin/python3 /home/user1/python_app.py
 12 [kworker/u16:0-kcryptd/253:0]

This datasource trims off the args to minimize possible PII and sensitive information. After trimming the data looks like this:

PID COMMAND
  1 /usr/lib/systemd/systemd
  2 [kthreadd]
  3 [rcu_gp]
  4 [rcu_par_gp]
  6 [kworker/0:0H-events_highpri]

0
Returns

All the missed pulp agent queues and the boolean mark if the data is

truncated in the last line. If the value of last line is 0, it means all the missed queues are returned. If the value of the last line is 1, it means there are a lot of missed queues, to avoid render error, only the first 10 missed queues are returned.

Return type
