Lpstat - command lpstat

Parsers contains in this module are:

LpstatProtocol - command /usr/bin/lpstat -v

LpstatQueuedJobs - command /usr/bin/lpstat -o

class insights.parsers.lpstat.LpstatPrinters(*args, **kwargs)[source]

Bases: CommandParser

Class to parse lpstat -p command output. Parses the output of lpstat -p, to get locally configured printers. Current available printer states are:

  • IDLE (PRINTER_STATUS_IDLE)

  • PROCESSING (PRINTER_STATUS_PROCESSING) -- printing

  • DISABLED (PRINTER_STATUS_DISABLED)

  • UNKNOWN (PRINTER_STATUS_UNKNOWN)

Sample output of the command:

printer idle_printer is idle. enabled since Fri 20 Jan 2017 09:55:50 PM CET printer disabled_printer disabled since Wed 15 Feb 2017 12:01:11 PM EST - reason unknown

Raises:

ValueError -- Raised if any error occurs parsing the content.

Examples: >>> type(lpstat_printers) <class ‘insights.parsers.lpstat.LpstatPrinters’> >>> len(lpstat_printers.printers) 3 >>> lpstat_printers.printer_names_by_status(‘DISABLED’) [‘disabled_printer’]

parse_content(content)[source]

This method must be implemented by classes based on this class.

printer_names_by_status(status)[source]

Gives names of configured printers for a given status

Parameters:

status (string) --

printers

Dictionary of locally configured printers, with keys ‘name’ and ‘status’

Type:

dict

class insights.parsers.lpstat.LpstatProtocol(context, extra_bad_lines=None)[source]

Bases: CommandParser, dict

Class to parse lpstat -v command output.

Sample output of the command:

device for test_printer1: ipp
device for test_printer2: ipp
device for savtermhpc: implicitclass:savtermhpc
device for A1: marshaA1:/tmp/A1

Examples

>>> type(lpstat_protocol)
<class 'insights.parsers.lpstat.LpstatProtocol'>
>>> lpstat_protocol['test_printer1']
'ipp'
>>> lpstat_protocol['savtermhpc']
'implicitclass'
parse_content(content)[source]

This method must be implemented by classes based on this class.

class insights.parsers.lpstat.LpstatQueuedJobs(context)[source]

Bases: Parser

Class to parse lpstat_queued_jobs_count datasource result to get the count of queued jobs.

Currently, this parser only provide one attribute count which returns the count of queued jobs but no detailed jobs are provided.

Sample output of the /usr/bin/lpstat -o command:

Cups-PDF-1804           root          265443328   Tue 05 Sep 2023 02:21:22 PM CST

Examples

>>> type(lpstat_queued_jobs)
<class 'insights.parsers.lpstat.LpstatQueuedJobs'>
>>> lpstat_queued_jobs.count
3
