opareport — Provides powerful fabric analysis and reporting capabilities.

Syntax

opareport [-v] [-q] [-h hfi] [-p port] [--timeout] [-o report] [-d level] [-P|-H] [-N] [-x] [-X snapshot_input] [-T topology_input] [-s] [-r] [-V] [-i seconds] [-b date_time] [-e date_time] [-C] [-a] [-m] [-M] [-A] [-c file] [-L] [-F point] [-S point] [-D point] [-Q]

Description

Must be run on a host connected to the CN5000 Omni-Path Fabric with the FastFabric Toolset installed.

Options

--help

Produces full help text.

-v/--verbose

Returns verbose output.

-q/--quiet

Disables progress reports.

-h/--hfi hfi

Specifies the SuperNIC, numbered 1..n. Using 0 specifies that the -p port port is a system-wide port number. Default is 0.

-p/--port port

Specifies the port, numbered 1..n. Using 0 specifies the first active port. Default is 0.

--timeout

Specifies the timeout (wait time for response) in ms. Default is 1000 ms.

-o/--output report

Specifies the report type for output. Refer to for details.

-d/--detail level

Specifies the level of detail 0-n for output. Default is 2.

-P/--persist

Only includes data persistent across reboots.

-H/--hard

Only includes permanent hardware data.

-N/--noname

Omits node and IOC names.

-x/--xml

Produces output in XML.

-X/--infile snapshot_input

Generates a report using the data in the snapshot_input file. snapshot_input must have been generated during a previous -o snapshot run. When used, the -s, -i, -C, and -a options are ignored. '-' may be used as the snapshot_input to specify stdin.

-T/--topology topology_input

Uses topology_input file to augment and verify fabric information. When used, various reports can be augmented with information not available electronically (such as cable labels). '-' may be used to specify stdin.

-s/--stats

Gets performance statistics for all ports.

-i/--interval seconds

Obtains performance statistics over interval seconds. Clears all statistics, waits interval seconds, then generates report. Implies -s option.

-b/--begin date_time

Obtains performance stats beginning at date_time. Implies -s option.

If -b/--begin and -e/--end are specified, the performance stats are provided over the specified interval.
If only -b/--begin is specified, the absolute value of the performance stats at the specified time is provided.

date_time may be a time entered as HH:MM[:SS] or date as mm/dd/YYYY, dd.mm.YYYY, YYYY-mm-dd or date followed by time; for example, "2016-07-04 14:40". Relative times are taken as "x [second|minute|hour|day](s) ago".

-e/--end date_time

Obtains performance stats ending at date_time. Implies -s option.

If -b/--begin and -e/--end are specified, the performance stats are provided over the specified interval.
If only -e/--end is specified, the absolute value of the performance stats at the specified time is provided.

-C/--clear

Clears performance statistics for all ports. Only statistics with error thresholds are cleared. A clear occurs after generating the report.

-a/--clearall

Clears all performance statistics for all ports.

-m/--smadirect

Accesses fabric information directly from SMA.

-M/--pmadirect

Accesses performance statistics using direct PMA.

-A/--allports

Gets PortInfo for down switch ports. Uses direct SMA to get this data. If used with -M, also gets PMA stats for down switch ports.

-c/--config file

Specifies the error thresholds configuration file. Default is /etc/opa/opamon.conf file.

-L/--limit

Limits operation to exact specified focus with -F for port error counters check (-o errors) and port counters clear (-C or -i). Normally, the neighbor of each selected port is also checked/cleared. Does not affect other reports.

-F/--focus point

Specifies the focus area for report.

Limits output to reflect a subsection of the fabric. May not work with all reports. (For example, route, mcgroups, and the verify* reports may ignore the option or not generate useful results.)

-S/--src point

Specifies the source for trace route. Default is local port.

-D/--dest point

Specifies the destination for trace route.

-Q/--quietfocus

Excludes focus description from report.

-h and -p options permit a variety of selections:

-h 0: First active port in the system (Default).
-h 0 -p 0: First active port in the system.
-h x: First active port on SuperNIC x.
-h x -p 0: First active port on SuperNIC x.
-h 0 -p y: Port y within the system (no matter which ports are active).
-h x -p y: SuperNIC x, port y.

Snapshot-Specific Options

-r/--routes: Gets routing tables for all switches.
-V/--vltables: Gets the PKey tables for all nodes and the QoS VL-related tables for all ports.

Other Information

opareport also supports operation with the Fabric Manager Performance Manager (PM)/Performance Manager Agent (PMA). When opareport detects the presence of a PM, it automatically issues any required PortCounter queries and clears to the PM to access the PMs running totals. If a PM is not detected, then opareport directly accesses the PMAs on all the nodes. The -M option can force access to the PMA even if a PM is present.

opareport takes advantage of these interfaces to obtain extensive information about the fabric from the subnet manager and the end nodes. Using this information, opareport is able to cross-reference it and produce analysis greatly beyond what any single subnet manager request could provide. As such, it exceeds the capabilities previously available in tools such as opasaquery and opafabricinfo.

opareport obtains and displays counters from the Fabric Manager PM/PA or directly from the fabric PMAs using the -M option.

opareport internally cross-references all this information so its output can be in user-friendly form. Reports include GUIDs, LIDs, and names for components. Obviously, these reports are easiest to read if the end user has taken the time to provide unique names for all the components in the fabric (node names and IOC names). All Cornelis components support this capability. For hosts, the node names are automatically assigned based on the network host name of the server. For switches and line cards, the names can be assigned using the element managers for each component.

Each run of opareport obtains up-to-date information from the fabric. At the start of the run opareport takes a few seconds to obtain all the fabric data, then it is output to stdout. The reports are sorted by GUIDs and other permanent information so they can be rerun in the future and produce output in the same order even if components have been rebooted. This is useful for comparison using simple tools like diff. opareport permits multiple reports to be requested for a single run (for example, one of each report type).

By default, opareport uses the first active port on the local system. However, if the Management Node is connected to more than one fabric (for example, a subnet), the SuperNIC and port may be specified to select the fabric to analyze.
