Subcommands

probe-create

Create probe port - create port and interface within a network namespace.

probe-list

List all probes.

probe-clear

Clear all probes.

probe-delete

Delete probe - delete port then delete the namespace.

probe-exec

Execute commands in the namespace of the probe.

ping-all

ping-all is an all-in-one command to ping all fixed IPs in a specified network.

neutron-debug optional arguments

--version

Show version number and exit.

-v, --verbose, --debug

Increase verbosity of output and show tracebacks on errors. Can be repeated.

-q, --quiet

Suppress output except warnings and errors

-h, --help

--os-auth-strategy <auth-strategy>

Authentication strategy (Env: OS_AUTH_STRATEGY, default keystone). For now, any other value will disable the authentication

--os-auth-url <auth-url>

Authentication URL (Env: OS_AUTH_URL)

--os-tenant-name <auth-tenant-name>

Authentication tenant name (Env: OS_TENANT_NAME)

--os-tenant-id <auth-tenant-id>

Authentication tenant name (Env: OS_TENANT_ID)

--os-username <auth-username>

Authentication username (Env: OS_USERNAME)

--os-password <auth-password>

Authentication password (Env: OS_PASSWORD)

--os-region-name <auth-region-name>

Authentication region name (Env: OS_REGION_NAME)

--os-token <token>

Defaults to env[OS_TOKEN]

--endpoint-type <endpoint-type>

Defaults to env[OS_ENDPOINT_TYPE] or public URL.

--os-url <url>

Defaults to env[OS_URL]

--os-cacert <ca-certificate>

Specify a CA bundle file to use in verifying a TLS (HTTPS) server certificate. Defaults to env[OS_CACERT]

--insecure

Explicitly allow neutron-debug to perform "insecure" SSL (HTTPS) requests. The server's certificate will not be verified against any certificate authorities. This option should be used with caution.

--config-file CONFIG_FILE

Config file for interface driver (You may also use l3_agent.ini)

neutron-debug probe-create command

usage: neutron-debug probe-create NET

Create probe port - create port and interface, then place it into the created network namespace.

Positional arguments

NET ID

ID of the network in which the probe will be created.

neutron-debug probe-list command

usage: neutron-debug probe-list

List probes.

neutron-debug probe-clear command

usage: neutron-debug probe-clear

Clear all probes.

neutron-debug probe-delete command

usage: neutron-debug probe-delete <port-id>

Remove a probe.

Positional arguments

<port-id>

ID of the probe to delete.

neutron-debug probe-exec command

usage: neutron-debug probe-exec <port-id> <command>

Execute commands in the namespace of the probe

neutron-debug ping-all command

usage: neutron-debug ping-all <port-id> --timeout <number>

All-in-one command to ping all fixed IPs in a specified network. A probe creation is not needed for this command. A new probe is created automatically. It will, however, need to be deleted manually when it is no longer needed. When there are multiple networks, the newly created probe will be attached to a random network and thus the ping will take place from within that random network.

Positional arguments

<port-id>

ID of the port to use.

Optional arguments

--timeout <timeout in seconds>

Optional ping timeout.

neutron-debug example

usage: neutron-debug create-probe <NET_ID>

Create a probe namespace within the network identified by NET_ID. The namespace will have the name of qprobe-<UUID of the probe port>

Note

For the following examples to function, the security group rules may need to be modified to allow the SSH (TCP port 22) or ping (ICMP) traffic into network.

usage: neutron-debug probe-exec <probe ID> "ssh <IP of instance>"

SSH to an instance within the network.

usage: neutron-debug ping-all <network ID>

Ping all instances on this network to verify they are responding.

usage: neutron-debug probe-exec <probe_ID> dhcping <VM_MAC address> -s <IP of DHCP server>

Ping the DHCP server for this network using dhcping to verify it is working.
