For example output of **diag** commands, see: :ref:`diag-command-examples`. :: platform@VOSS:~$ diag USAGE: ------ diag config [] - Display configuration, optionally specifying the configuration prefix, diag config /platform/network/name diag config app [] - Display application configuration, optionally specifying the configuration prefix, eg diag config app snmp /community diag date - Convert epoch timestamp to datetime diag disk - Display diagnostics for disk usage diag epoch - Convert datetime to epoch timestamp diag fileguard - Run a file integrity check using AIDE (Advanced Intrusion Detection Environment) to detect unauthorized or unexpected changes to critical system files. diag free - Display diagnostics relating to free memory diag health - Display a health report diag health report - Save a health report as a logfile diag iostat - IO subsystem statistics diag largefiles - Find the largest files on your system no more than the top 10 items are display diag mem - Display memory diagnostics diag monitor - Display the system resource analysis diag monitor list - Display the long-term average and maximum system resource usage diag nicstat - Network interface statistics diag ntp - Display ntp status diag ping - Ping a remote host to test network reachability diag proc - Display a list of system processes diag resolve - Resolve a hostname to IP address diag stats - Display the container statistics diag tasks - Display constant task listing diag test_connection - Test if system can open a connection to a remote port diag top - Process resource statistics diag traceroute - Discover the network path to diag vmstat - Virtual memory subsystem statistics .. rubric:: Command Descriptions Some of the commands are provided with details below: .. tabularcolumns:: |p{5cm}|p{9cm}| +----------------------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | Command | Description | +========================================+===========================================================================================================================================================================================================================================================================+ | **diag ping ** | Test network reachability to a network host. | +----------------------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | **diag resolve ** | Test DNS resolution of a hostname. | +----------------------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | **diag test_connection ** | Given a host IP and port number, return a message: "Successfully connected to :" or "Failed to connect to :". | +----------------------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | **diag free** | Display the memory usage. | +----------------------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | **diag disk** | Display the disk usage. Logical volumes for the database have the format ``/dev/mapper/voss-dbroot``. | +----------------------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | **diag largefiles** | Display up to 10 largest files on the system over 1GB in size, else no files are shown. | +----------------------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | **diag mem** | Display a more detailed memory usage by process. | +----------------------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | **diag ntp** | Display details of ntp server, including peers and host addresses. Equivalent to the ``ntp -pn`` command. | +----------------------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | **diag health** | Display a comprehensive health summary. This includes status on the following: CPU, Memory, Disk, Security Update, Application, Cluster, Cluster Failover and Health email scheduling. Logical volumes used by the database have the format: ``/dev/mapper/voss-dbroot``. | +----------------------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | **diag top** | Display a single Unix top summary. | +----------------------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | **diag unittests** | Utility for developers only. Note that services will be restarted by this utility. | +----------------------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | **diag fileguard** | Although a checksum of system and configuration files is carried out regularly, a manual check for changes since the previous check can be carried out. If any files have changed, these will be listed in the command output. | | | File tamper detection and integrity monitoring is also carried out. If any files have changed, these will be listed in the command output. | +----------------------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ For **diag health**, see also :ref:`diagnostic-troubleshoot`. .. |VOSS Automate| replace:: VOSS Automate .. |Unified CM| replace:: Unified CM
