class insights.parsers.systemctl_show.SystemctlShowAllServiceWithLimitedProperties(context, extra_bad_lines=None)[source]

Bases: insights.parsers.systemctl_show.SystemctlShowServiceAll

Class for parsing the output of command systemctl show *.service --all --property=<...>.

Sample Input:

CPUAccounting=no

StartupCPUShares=18446744073709551615
CPUQuotaPerSecUSec=infinity
Names=test2.service
SubState=dead
UnitFileState=enabled

Sample Output:

{'test1.service': {
    'Names': 'test1.service',
    'SubState': 'dead',
    'UnitFileState': 'static',
    'CPUQuotaPerSecUSec': 'infinity',
    'CPUShares': '18446744073709551615',
    'StartupCPUShares': '18446744073709551615',
    'CPUAccounting': 'no'
    },
'test2.service': {
    'Names': 'test2.service',
    'SubState': 'dead',
    'UnitFileState': 'enabled',
    'CPUQuotaPerSecUSec': 'infinity',
    'CPUShares': '18446744073709551615',
    'StartupCPUShares': '18446744073709551615',
    'CPUAccounting': 'yes'
    }
}

Examples

>>> 'test1.service' in all_services_with_limited_info
True
>>> all_services_with_limited_info.get('test1.service').get('CPUAccounting', None)
'no'
>>> 'test2.service' in all_services_with_limited_info.get_services_with_cpuaccouting_enabled()
True
get_services_with_cpuaccouting_enabled()[source]

Return a list of service names which enables the CPUAccounting.

class insights.parsers.systemctl_show.SystemctlShowServiceAll(context, extra_bad_lines=None)[source]

Bases: insights.core.CommandParser, dict

Class for parsing systemctl show *.service command output. Empty properties are suppressed.

Sample Input:

LimitLOCKS=18446744073709551615

Id=postgresql.service
Names=postgresql.service
Requires=basic.target
LimitMSGQUEUE=819200
LimitNICE=0

Sample Output:

{
    "postfix.service": {
        "Id"               : "postfix.service",
        "Names"            : "postfix.service",
        "LimitNOFILE"      : "65536",
        "TimeoutStartUSec" : "1min 30s",
        "LimitLOCKS"       : "18446744073709551615",

        "LimitMSGQUEUE"    : "819200",
        "LimitNICE"        : "0",
    }
}

Examples

>>> 'postfix' in systemctl_show_all  # ".service" is needed
False
>>> 'postfix.service' in systemctl_show_all
True
>>> systemctl_show_all['postfix.service']['Id']
'postfix.service'
>>> 'LimitMEMLOCK' in systemctl_show_all['postfix.service']
False
>>> systemctl_show_all['postfix.service']['LimitLOCKS']
'18446744073709551615'
>>> 'postgresql.service' in systemctl_show_all
True
>>> systemctl_show_all['postgresql.service']['LimitNICE']
'0'
Raises:
  • SkipComponent -- When nothing needs to parse
  • ParseException -- When something cannot be parsed
