# ibcheckerrs(8)

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

## NAME

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

## SYNOPSIS

**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

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

\-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

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
