Parses /proc/lve/list and produces a small set of metrics that let us answer: - does this kernel expose net accounting at all (NETO/NETI columns present)? - how many user LVEs exist and how many actually accumulated traffic? - what's the cumulative NETO/NETI volume across user LVEs on this host? /proc/lve/list contains two non-user LVE rows we exclude from all aggregates: - *default* (user_id = UINT_MAX) — kernel catch-all for processes not attached to any specific LVE (sshd, systemd, dnf, ...). Has non-zero traffic on essentially every running CL host. - *root* (user_id = 0) — LVE container for root (uid 0). Not a hosting user. After exclusion the metrics describe user hosting activity, and lves_total matches the count seen by `lvectl list` and the panel's user list. � N)�Dict�Iterable�Optionalz/proc/lve/listl �� ��net_acct_kernel_supported�net_acct_lves_total�net_acct_lves_with_traffic�net_acct_total_neto_bytes�net_acct_total_neti_bytes� lve_id_field�excluded�returnc � � | � dd� � d } t |� � |v S # t $ r Y dS w xY w)z�True if the LVE row's user_id is in the excluded set.

Format of /proc/lve/list: <version>:<TAB>LVE<TAB>...<TAB>NETO<TAB>NETI # header <lve_id><TAB>...<TAB><neto><TAB><neti> # one row per LVE The leading "<version>:" prefix is optional/version-dependent; we tolerate its presence and absence. NETO/NETI are cumulative byte counters; their lowercase counterparts lNETO/lNETI are limit columns and ignored here. skip_user_ids — additional user-id slots to exclude beyond the standard root/default. Used by cloudlinux-summary to skip its own transient self-LVE (created via _run_self_in_lve) which would otherwise inflate counts by 1 on every collection run. On any structural problem (no header, missing NETO/NETI columns, malformed rows) we treat the kernel as not supporting net accounting and return a zeroed result. r �:r � �NETO�NETINr ) r � splitlines�split�indexr �set�NON_USER_LVE_IDS�update�strip�len�maxr r )r r �lines�header�columns�neto_idx�neti_idx� excluded_ids�total� with_traffic�sum_neto�sum_neti�raw�fields�neto�netis r �parse_proc_lve_listr< B s � �. � � ��� � � � � � �E� � � ��� � �1�X�F� �f�}�}�� � �c�1�%�%�a�(���l�l�4� � �G� ��=�=��(�(���=�=��(�(���� � � � � ��� � � � ���� �'�(�(�L�� +����M�*�*�*� �E��L��H��H��Q�R�R�y� � ���y�y�{�{� � ����4� � �� �v�;�;�#�h��1�1� 1� 1� � �V�A�Y� � 5� 5� � � ��v�h�'�(�(�D��v�h�'�(�(�D�D��� � � � �H� ���� �� �� �!�8�8�t�a�x�x� �A� �L��D����D���� &'� $�&2�%-�%-� � � s$ �3*B � B9�8B9� *F � F�F�pathc �< � t j � | � � st � � S t | ddd�� � 5 }|� � � }ddd� � n # 1 swxY w Y n # t $ r t � � cY S w xY wt ||�� � S )z�Read /proc/lve/list and return parsed metrics.
