VNF Fault Management¶
This document describes how to manage VNF Fault with CLI in Tacker.
Prerequisites¶
The following packages should be installed:
tacker
python-tackerclient
CLI Reference for VNF Fault Management¶
Note
To call the VNF FM API with vnffm subcommand, you need to use the option –os-tacker-api-version 2
1. List alarms¶
$ openstack vnffm alarm list --os-tacker-api-version 2

Maximum display width, <1 to disable. You can also use the
CLIFF_MAX_TERM_WIDTH environment variable, but the parameter takes
precedence.
--fit-width Fit the table to the display width. Implied if --max-width greater than
0. Set the environment variable CLIFF_FIT_WIDTH=1 to always enable
--print-empty Print empty table if there is no data to show.
2. Show alarm¶
The <vnf-fm-alarm-id> should be replaced with the ‘ID’ in result of ‘1. List alarms’. In the following sample, d59545c5-6882-47a2-85aa-b25a5a0591c0 is used.
$ openstack vnffm alarm show <vnf-fm-alarm-id> --os-tacker-api-version 2
