Note about "available" memory: up until psutil 4.3 it was calculated as "avail = (free + buffers + cached)". Now "MemAvailable:" column (kernel 3.14) from /proc/meminfo is used as it's more accurate. That matches "available" column in newer versions of "free". � %s/meminfor � r Ns MemTotal:r� s Buffers:rU r� rV r� s Shmem:s MemShared:rW s Active:rS s Inactive:s Inact_dirty:s Inact_clean:s Inact_laundry:rT s Slab:s MemAvailable:rO �Zround_z6%s memory stats couldn't be determined and %s set to 0�, ZwasZwere)r r r{ r� r� r� r� r� r �joinr� �warnings�warn�RuntimeWarningrM )Zmissing_fieldsr� r� r� r� rN rR rU rV rW rS rT rX rQ r� rP �msgr? r? r@ �virtual_memory� s� 8 ��� � �r� c C s� i } t dt� ��:}|D ]$}|�� }t|d �d | |d < qW d � n1 sR0 Y z| d }| d }W n8 ty� t�� \}}}}}}}||9 }||9 }Y n0 || }t||dd�} zt d t� �}W nF t�y } z,d t | � } t � | t � d } } W Y d} ~ n�d} ~ 0 0 |�� d } } |D ]n}|� d ��rXt|�d �d �d d } n&|� d��r~t|�d �d �d d } | du�r,| du�r, �q��q,d} t � | t � d } } W d � n1 �s�0 Y t�|||| | | �S )zReturn swap memory metrics.r� r r� r Ns SwapTotal:s SwapFree:r� z %s/vmstatzP'sin' and 'sout' swap memory stats couldn't be determined and were set to 0 (%s)s pswpin� r# s pswpoutzK'sin' and 'sout' swap memory stats couldn't be determined and were set to 0)r r r{ r� r� �cextZ linux_sysinfor r� �strr� r� r� r� r Zsswap)r� r� r� r� rN rR �_Zunit_multiplierrQ rP �errr� ZsinZsoutr? r? r@ � swap_memory sF 8 � (r� c C sr t � } t| � td| �� }|�� �� }W d � n1 s<0 Y |dttj�d � }dd� |D �}t|� S )z�Return a named tuple representing the following system-wide CPU times: (user, nice, system, idle, iowait, irq, softirq [steal, [guest, [guest_nice]]]) Last 3 fields may not be available on all Linux kernel versions. r� Nr c S s g | ]}t |�t �qS r? ��float� CLOCK_TICKSr� r? r? r@ r� ^ r� z cpu_times.<locals>.<listcomp>)r r� r r� r{ r� r� �_fields)r� r� r� r� r? r? r@ � cpu_timesR s *r� c C s� t � } t| � g }td| ��n}|�� |D ]L}|�d�r,|�� }|dttj�d � }dd� |D �}t|� }|� |� q,|W d � S 1 s�0 Y dS )zfReturn a list of namedtuple representing the CPU times for every CPU available on the system. r� s cpur c S s g | ]}t |�t �qS r? r� r� r? r? r@ r� p r� z!per_cpu_times.<locals>.<listcomp>N) r r� r r� r� r{ r� r� r� r� )r� �cpusr� r� r� r� �entryr? r? r@ � per_cpu_timesb s r� c C s� z t �d�W S ty� d} tdt� ��0}|D ]}|�� �d�r2| d7 } q2W d � n1 sb0 Y | dkr�t�d�}t dt� ��:}|D ]$}|� d �d }|� |�r�| d7 } q�W d � n1 s�0 Y | dkr�Y dS | Y S 0 dS ) z0Return the number of logical CPUs in the system.�SC_NPROCESSORS_ONLNr � %s/cpuinfos processorr Nzcpu\dr� rm ) ry �sysconf� ValueErrorr r �lowerr� �re�compiler r{ �match)�numr� r� �searchr? r? r@ �cpu_count_logicalv s$ ( (r� c C s2 t � } d}d}t�|�p t�|�D ]>}t|��"}| �|�� �� � W d � q"1 sV0 Y q"t| �}|dkrv|S i }i }tdt� ��~}|D ]h}|�� �� }|s�z|d ||d < W n t y� Y n0 i }q�|� d�r�|� d d �\} } t | �|| < q�W d � n1 �s0 Y t |�� �}|�p0dS ) z2Return the number of physical cores in the system.z9/sys/devices/system/cpu/cpu[0-9]*/topology/core_cpus_listz?/sys/devices/system/cpu/cpu[0-9]*/topology/thread_siblings_listNr r� � cpu cores� physical id)r� r� s :r )�set�globr �addr� r� r� r r� r� r� r{ r� �sumr� ) �lsZp1Zp2r` r� �result�mappingZ current_infor� �key�valuer? r? r@ �cpu_count_physical� s4 2 � . r� c C s� t dt� ���} d}d}d}| D ]r}|�d�r@t|�� d �}n6|�d�r\t|�� d �}n|�d�rvt|�� d �}|dur |dur |dur q�q W d � n1 s�0 Y d}t�||||�S )z*Return various CPU stats as a named tuple.r� Ns ctxtr s intrs softirqr )r r r� r� r{ r Z scpustats)r� Z ctx_switchesZ interruptsZsoft_interruptsr� Zsyscallsr? r? r@ � cpu_stats� s& �$�r� z'/sys/devices/system/cpu/cpufreq/policy0z$/sys/devices/system/cpu/cpu0/cpufreqc C s� dd� } g }t t� �D ]�}| |�}|s(qtjj}t||d�dd�}|du rlt||d�dd�}|du rltd��t|�d }tt||d ���d }tt||d ���d }|�t � |||�� q|S ) z�Return frequency metrics for all CPUs.
