Port Counters

--per_slvl_cntrs

Provides a report of all per sl/vl port counters (if supported by devices)
These counters are reported in ibdiagnet2.db_csv file.

-

--sc

Provides a report of NVIDIA Diagnostic counters in ibdiagnet2.mlnx_cntrs file and ibdiagnet2.db_csv.

-

--scr

Resets all the NVIDIA Diagnostic counters (should be used with -sc option).

ibdiagnet --scr --sc

--extended_speeds <dev-type>

Collects and tests port extended speeds counters.
Supported dev-type:

• sw (switch only)

• all (all devices)

These counters are reported in ibdiagnet2.db_csv file (PM_INFO section).

-

--pm_per_lane

Lists all counters per lane (if supported by devices). Should be used on combination with --extended_speeds.

ibdiagnet --extended_speeds all --pm_per_lane

--pm_get_all

Get all PM counters. activate the following flags:
--per_slvl_cntrs
--sc
--extended_speeds all
--pm_per_lane

ibdiagnet --pm_get_all

-P | -counter <<PM>=<value>>

If any of the provided counter is greater than its provided value, then print it.

If 'all' is used, all counters get the same threshold (0 by default).

ibdiagnet -P vl15_dropped=1, port_xmit_discard=1

or

ibdiagnet -P vl15_dropped=1 -P port_xmit_discard=1

or

ibdiagnet -P all

--pc

Resets all fabric IB spec compliant port counters (PortCounters and PortCountersExtended), RN, AR and HBF counters.

Note: It is recommended to use this option with –reset_phy_info, as both options have cross counters and using only one of them can be confusing on the next iteration of counters or registers collection.

--pm_clear_all

Clear all PM counters. activate the following flags:
--scr
--p

--pm_pause_time <seconds>

Specifies a delay (in seconds) between counters samples. If set to 0, only single sampling is performed. (default - 1 second)
The delta between the first and the second counter samples will be written to the PM_DELTA section in db_csv file.

ibdiagnet --pm_pause_time 60
