PmLogSummary - Command pmlogsummary

class insights.parsers.pmlog_summary.PmLogSummary(context, extra_bad_lines=None)

Bases: CommandParser, dict

Parser to parse the output of the pmlogsummary command

Sample output of the command is:

mem.util.used  3133919.812 Kbyte
mem.physmem  3997600.000 Kbyte
kernel.all.cpu.user  0.003 none
kernel.all.cpu.sys  0.004 none
kernel.all.cpu.nice  0.000 none
kernel.all.cpu.steal  0.000 none
kernel.all.cpu.idle  3.986 none
kernel.all.pressure.io.full.avg ["10 second"] 0.001 none
kernel.all.pressure.cpu.some.avg ["1 minute"] 14.942 none
kernel.all.pressure.memory.full.avg ["5 minute"] 0.002 none
disk.all.total  0.252 count / sec
disk.dev.total ["vda"] 0.016 count / sec
disk.dev.total ["vdb"] 0.445 count / sec
disk.dev.total ["vdc"] 2.339 count / sec

Output is parsed and stored as a dictionary. Each value is stored as a dict in the form {'val': number or string, 'units': string}. Keys are a hierarchy of the input key value split on the “.” character.

For instance:

1. Input line "mem.util.used  3133919.812 Kbyte" is parsed as:
    {
        'mem': {
            'util': {
                'used': {
                    'val': 3133919.812,
                    'units': 'Kbyte'
                }
            }
        }
    }
2. Input line "disk.dev.total ["vdc"] 2.339 count / sec" is parsed as:
    {
        'disk': {
            'dev': {
                'total': {
                    'vdc': {
                        'val': 2.339
                        'units': 'count / sec'
                    }
                }
            }
        }
    }

Example

>>> type(pmlog_summary)
<class 'insights.parsers.pmlog_summary.PmLogSummary'>
>>> 'mem' in pmlog_summary
True
>>> pmlog_summary['disk']['all']['total'] == {'val': 0.252, 'units': 'count / sec'}
True
>>> pmlog_summary['disk']['dev']['total']['vdc'] == {'val': 2.339, 'units': 'count / sec'}
True
>>> pmlog_summary['kernel']['all']['pressure']['memory']['full']['avg']['5 minute'] == {'val': 0.002, 'units': 'none'}
True
