IBCHECKERRS(8)              OpenIB Diagnostics             IBCHECKERRS(8)

NAME         top

       ibcheckerrs - validate IB port (or node) and report errors in
       counters above threshold

SYNOPSIS         top

       ibcheckerrs [-h] [-b] [-v] [-G] [-T <threshold_file>]
       [-s(how_thresholds)] [-N | -nocolor] [-C ca_name] [-P ca_port]
       [-t(imeout) timeout_ms] <lid|guid> <port>

DESCRIPTION         top

       Check specified port (or node) and report errors that surpassed
       their predefined threshold. Port address is lid unless -G option
       is used to specify a GUID address. The predefined thresholds can
       be dumped using the -s option, and a user defined threshold_file
       (using the same format as the dump) can be specified using the -t
       <file> option.

OPTIONS         top

       -G      use GUID address argument. In most cases, it is the Port
       GUID.
               Example:
               "0x08f1040023"

       -s      show predefined thresholds

       -T      use specified threshold file

       -v      increase the verbosity level

       -b      brief mode. Reduce the output to show only if errors are
               present, not what they are.

       -N | -nocolor use mono rather than color mode

       -C <ca_name>    use the specified ca_name.

       -P <ca_port>    use the specified ca_port.

       -t <timeout_ms> override the default timeout for the solicited
       mads.

EXAMPLE         top

       ibcheckerrs 2           # check aggregated node counter for lid 2

       ibcheckerrs 2   4       # check port counters for lid 2 port 4

       ibcheckerrs -T xxx 2    # check node using xxx threshold file
