Media Flow Controller Fault Management : Displaying Information Using Show Commands

Displaying Information Using Show Commands
Media Flow Controller show commands let you find the system information you need. This section excludes commands that show settings deemed not useful for fault management, including show commands for banner, cli, clock, delivery, email, ip, license, logging, ntp, radius-server, snmp-server, ssh, tacacs-server, telnet, terminal, username, web, and whoami. See Table 11, “Logging Status (%s) Codes and Table 12, “Logging Status Sub-Codes for descriptions of HTTP response codes and sub-codes you may see.
show analytics—Analytics manager default settings (shown); these include:
Note! In Release 2.0.2, you can configure some of these settings with analytics commands.
show bootvar— The installed images on partition 1 and partition 2, from which partition was the last boot, and which partition is set as the next boot.
show configuration— Lists the CLI commands needed to bring the state of a fresh system up to match the current persistent (saved) state of this system. A short header is included, containing the name and version number of the configuration, in a comment. Commands that have not been saved, or would set something to its default, are not included, so this command on a fresh configuration produces no output, except the header. Includes arguments:
files [<filename>]—If no filename is specified, display a list of configuration files in persistent storage. If filename is specified, display the commands to recreate the configuration in that file; only non-default commands are shown.
full—Same as show configuration but includes commands that set default values.
running—Same as show configuration except that it applies to the currently running configuration, rather than the active saved configuration.
text files—Display text-based configuration files.
show counters—The following information (below). See “Log Codes and Sub-Codes” on page 115,” for descriptions of HTTP response codes:
show files—List available files or display their counters. Includes these arguments:
debug-dump—List of debug dump files.
stats—List of statistics reports.
system—Filesystem information; includes these statistics for /config and /var:
tcpdump—Display tcpdump files.
show hosts—Hostname, DNS configuration, and static host mappings.
show images—Information about system images and boot parameters.
show interface [configured]—Information about each system interface including:
Admin state—Whether or not the interface is enabled.
Link state—Up means there is a cable plugged into that interface and it is “live” – connected to something which is turned on at the other side, i.e. a switch, router, or another computer.
Current TX (transmissions out) and RX (transmissions received) statistics.
Use configured to see the settings of the interfaces, rather than their runtime state.
show log—View event logs including commands executed during this session.
show media-cache disk—The list argument displays available caches and information on each including Device (name), Type, (cache), Tier (1=SSD, 2=SAS, 3=SATA), Active status, Enabled status, Free Space, and Disk State. Use show media-cache disk <disk_name> for details on a particular disk.
show media-cache free-block threshold—The free-block threshold argument displays the free-block threshold of the disk caches.
show memory—Memory usage; includes Total, Used, and Free for Physical and Swap.
show namespace—Use the list argument to display a list of configured namespaces and their UIDs; use show namespace <namespace_name> to display settings for the specified namespace. Tip! Use namespace <name> object list {all | URI | pattern} to see all objects stored in Media Flow Controller for that namespace URI; for more information, see “(namespace) object list | delete | revalidate” on page 212.
show network—Network configurations; includes time out, max connections, session assured flow rate, and session max bandwidth settings.
show ram-cache—Buffer-manager configuration; defaults are sync-interval = 86400 seconds, object minimum size = 0 (zero), revalidate-window = 120 seconds, and maximum RAM cache size = 0 (zero) or AUTO. Also displays current RAM cache size.
show running-config—Displays commands to recreate the currently running configuration.
show service—Configuration and status (current status, number of failures, last terminated, and uptime) for these services: delivery (mod-delivery), offline origin manager (mod-oom), pre-stage FTP (mod-ftp), accesslog and errorlog (mod-log), and FMS service (mod-rtmp-fms and mod-rtmp-admin).
show statistics—Key statistics; including:
Current Bandwidth (MB/Sec)—The rate at which Media Flow Controller is currently delivering the service.
Current Cache Bandwidth (MB/Sec)—The delivery bandwidth at which Media Flow Controller is delivering from cache, excluding deliveries from the origin directly.
Current Disk Bandwidth (MB/Sec)—The delivery bandwidth coming from objects in the disk; should be a subset of Current Cache Bandwidth.
Current Origin Bandwidth (MB/Sec)—The delivery bandwidth for objects being fetched from the origin and directly delivered.
Avg Number of Connections Per Sec—On average, the connection acception rate.
Avg HTTP Transactions per Sec—On average, number of completed HTTP transactions.
Avg Cache Bandwidth (MB/Sec)—On average, the data fetch rate from buffer to network for delivery.
Avg Disk Bandwidth (MB/Sec)—On average, the data fetch rate from disk.
Avg Origin Bandwidth (MB/Sec)—On average, the data fetch rate from origin (happens only when there is a cache miss).
Avg Proxy Rate (Origin Manager) (MB/Sec)—Total bytes received from origin, sampled every 5 seconds and averaged since Media Flow Controller start.
Current Proxy Rate in this sec (MB/Sec)—Rate of GET requests made in one second.
Per Disk Bandwidth (MB/Sec)—Lists available disks and the bandwidth for each.
show stats <type>—Display statistics (stats) settings and gathered data; includes these statistic types (see stats for CLI details on alarm, chd, and sample types):
alarm—Display status and configuration of statistics-based alarms.
chd—Display configuration of statistics CHDs.
cpu—Display CPU statistics.
sample—Display configuration of statistics samples.
show system—Displays system configuration (debug level and mod).
show users—Displays information about user logins.
show version—Displays version information for current system image.
show virtual-player—Displays virtual player settings; use list to se a list of defined virtual players and their type, use <name> to see settings.
