Overview

The Cloud Diagnostic tool, also known as cloud_diags.py script, facilitates debugging of Ribbon cloud devices. You can use this tool as a test agent on all Ribbon cloud instances as well as in production cloud environments where users only have access to the VM hosting the Ribbon instance.

Note

The Cloud Diagnostic tool is currently supported on the SBC, PSX and EMS SWe platforms.

Supported diagnostics

System information

- CPU information
- Platform information
- Storage information
- Memory information
- Basic disk IOPS
- Network interfaces information
- Check if Metadata supported
- Check if Config-drive supported
- Check if DHCP used
- Check if SBC SR-IOV supported
Network connectivity and performance testing
- Packet load throughput measurements on specified interfaces (mgtx, pktx) for different packet sizes (TCP/UDP)
- Request/response round trip measurements (latency) with time stamps

Prerequisites

Create an IP Access Control List (ACL) rules (only for SBC) that is used to allow access to incoming IP packets. A separate ACL rule is required for each protocol type. The ACL rule allows a packet on a specific IP address/port and can be configured to have an “fillRate” and “bucketSize” set to “Unlimited”. For additional information, refer to Working with Access Control Lists.

An example of a user generated ACL rule on SBC CLI:

set addressContext default ipAccessControlList rule <rule_name> protocol tcp destinationIpAddress <destination_ip> destinationAddressPrefixLength <dest_prefix_len> destinationPort any precedence <precedence_no>
set addressContext default ipAccessControlList rule <rule_name> bucketSize unlimited fillRate unlimited
set addressContext default ipAccessControlList rule <rule_name> state enabled
commit

Limitations: Even with the ACL rule configured to Unlimited; the rule is limited by the Operator Aggregate Policer. The total amount of bandwidth allowed on the device is as follows:

Hard coded to 20,000 packets/second
Based on a calculation of 1500 bytes/packet. Expect to get up to 1500 bytes * 8 bytes/bit * 20000 pkts = 240Mbit/second

CLI Examples

Note

The outputs displayed in this section may differ based on the actual system configurations and various other requirements. You may consider the outputs as an example.

The Cloud Diagnostic tool consists of following commands, each of these commands accomplishes one or more feature described in the feature overview section.

To run on an SBC system, ssh to the SBC Linux shell as linuxadmin user. The script is in /home/linuxadmin/cloud_diags/cloud_diags.py directory.
To run on a PSX or an EMS system, ssh to the system Linux shell as root user. The script is in /root/cloud_diags/cloud_diags.py directory.

Note

Within the tool, command names are case-sensitive and required to be entered as shown. Tab completion is supported for command names.

startNetworkServer

This command runs test server with parameters. The user is required to select the protocol type, IP address and optional port for the test. The server acts as a listener for that protocol type; receives and forwards messages from/to the Client.

To start the server from the diagnostics tool menu, execute below command:

startNetworkServer -p <protocol_type> --li <servers_local_ip> [--lp <servers_local_port_no>]

Mandatory Parameters
Parameter	Description / Usage	Example
-p	Specify the Protocol Type of test server. Values: TCP UDP	TCP/UDP
--li	Specify the Local Server IP (IPv4 or IPv6) address.	IPV4 and Protocol - startNetwrokServer -p tcp --li 1.1.1.1 IPV6 and Protocol - startNetwrokServer -p udp --li 2001:0DB8:AC10:FE01::
Optional Parameters
Parameter	Description / Usage	Example
--lp	Specify the Local Server Port Number. Values: TCP: 1024 – 65535. Default TCP - 40000 UDP: 5060 or 5061. Default UDP - 5061 If the user does not specify a Port Number, a default port number is assigned.	IP (IPV4 or IPV6), Protocol, and Port - startNetwrokServer -p tcp --li 1.1.1.1 --lp 5061

This diagnostics tool is running as TCP Server to receive on IP = fd00:10:6b50:42c0::1c1 port = 40000
Waiting ...
             Enter Ctrl-c to exit server mode and return to command prompt

Note

When the diagnostics tool runs as a server, it listens to the port specified in --lp (or default port), and responds to any incoming packet from the client. The standard output connected to the server displays the message "Waiting ...", without displaying any further information. To exit the server mode and return to the command prompt, press the Ctrl+C key combination.

startNetworkTest

This command runs client side performance test. The Client side is responsible for running the test and sending packets to the server. Server should be running when the client test is started.

To start the client test from the diagnostics tool menu, execute below command:

startNetworkTest -p  <protocol_type> --si <remote_server_ip> [--sp <remote_server_port_no>] --li <local_ip> [--lp <local_port_no>] [-r <msg_rate_per_sec>] [-m <message_size>] [-c <run_count>]

Mandatory Parameters
Parameter	Description / Usage	Length/Range	Example
-p	Specify the Protocol Type of test server Values: TCP UDP	N/A	TCP/UDP
--si	Specify the Remote Server IP (IPv4 or IPv6) address.	N/A	IP4: 1.1.1.1 IPV6: 2001:0DB8:AC10:FE01::
--li	Specify the Local Server IP (IPv4 or IPv6) address. Mandatory for TCP and not applicable for UDP.	N/A	IP4: 1.1.1.1 IPV6: 2001:0DB8:AC10:FE01::
Optional Parameters
Parameter	Description / Usage	Length/Range	Example/Default Value
--sp	Specify the Remote Server Port Number. If the user does not specify a Port Number, a default port number is assigned.	TCP: 1024 - 65535 UDP: 5060 or 5061	TCP - 40000 UDP - 5061
--lp	Specify the Local Client Port Number. This parameter is not applicable for UDP protocol.	TCP: 1024 - 65535	TCP - 20000
-r	Specify Message Rate Per Second.	1- 10000	1000
-m	Specify Message Size.	100-10000	500
-c	Specify Run Count (the number of time the test is to be run).	1-100	1
-f	Specify whether test result is written to a file. If, -f flag is specified, the result is displayed and exported to a text file. Naming convention of a text file: SBC - Specifies the application name. vsbc - Specifies the host name. YYYYMMDD-HHMMSS - Specifies the date/time of file is created.

startMessageSizeTest

This command runs client side message size test. The Client side is responsible for running the test and sending packets to the server.

To start the message size test from the diagnostics tool menu, execute below command:

startMessageSizeTest -p  <protocol_type> --si <remote_server_ip> [--sp <remote_server_port_no>]

Mandatory Parameters
Parameter	Description / Usage	Length/Range	Example/Default Value
-p	Specify the Protocol Type of test server, only UDP is allowed.	N/A	UDP
--si	Specify the Remote Server IP (IPv4 or IPv6) address. Note: IP type must match in both server and message size test client to be successful.	N/A	IP4: 1.1.1.1 IPV6: 2001:0DB8:AC10:FE01::
Optional Parameters
Parameter	Description / Usage	Length/Range	Example/Default Value
--sp	Specify the Remote Server Port Number. If the user does not specify a Port Number, a default port number is assigned.	5060 or 5061	5061

Example Usage – UDP

Scenario	Command
User has All Parameters	startMessageSizeTest -p udp --si 1.1.1.1 --sp 5061
User has
IPv 4 and Protocol	startMessageSizeTest -p udp --si 1.1.1.1
IPv 6 and Protocol	startMessageSizeTest -p udp --si 2001:0DB8:AC10:FE01::

Note

Ensure server is active before running client message size test to be successful.

quit/exit

Each of the command allows user to exit from the command mode of tool.

Command syntax: quit / exit

Example: Exit from tool command prompt and return to Linux terminal command prompt.

(Enter command or ?) : ?
