check_ib_switch.py

This tool is used to monitor unmanaged Infiniband switches made by Mellanox. This script is using mlxreg_ext to query the register on the switches. The information could have errors since some guesswork is involved.

Requirements

• mgt
• python3

Usage

This script is intended to be used with NRPE.

A switch can be accessed with its GUID or the combination of its name and the path to a node name map file.

The --cable option will also query each transciver to get their temperature. It will also display the cable information like its part number and length.

usage: check_ib_switch.py [-h] [-v] [--guid GUID]
                          [--node_name_map NODE_NAME_MAP] [--name NAME]
                          [--fan] [--cable] [--psu] [--temp]

optional arguments:
  -h, --help            show this help message and exit
  -v, --verbose         increase output verbosity
  --guid GUID           Switch GUID to check
  --node_name_map NODE_NAME_MAP
                        Node name map file path
  --name NAME           Switch name used in node-name-map
  --fan                 Check fans
  --cable               Check cables
  --psu                 Check PSUs
  --temp                Check temperatures

Example

Serial numbers and switch name is redacted.

check_ib_switch.py --name switch0 --node_name_map /etc/node-name-map --psu --temp --fan --cable
