This page contains basic instructions required when trying to run and test Honeycomb agent. Before proceeding, check Honeycomb/Setting_Up_Your_Dev_Environment to get more information about setting up required environment with VPP and Honeycomb

If there already is environment with VPP and it's just Honeycomb that's missing, it can be downloaded straight from FD.io nexus

Starting Honeycomb agent

The v3po distribution can be started by invoking:

 sudo ./karaf/target/assembly/bin/karaf

This will start karaf with all ODL dependencies and Honeycomb agent. It will automatically initialize vpp-japi to create interface between VPP and Honeycomb

Testing Honeycomb agent

There are multiple ways of testing Honeycomb agent, depending on e.g. which northbound interface will be used

Using NETCONF Northbound

Netconf northbound can be easily tested manually using CLI SSH client. Initialize SSH connection by invoking:

 ssh admin@localhost -p 2830 -s netconf

Note: Using default credentials admin/admin, default port 2830 and netconf SSH channel Note: "Are you sure you want to continue connecting (yes/no)?" Answer yes

Next thing to do is to provide client hello message to initialize netconf session. Following content must be copy&pasted into SSH session + hit enter:

<hello xmlns="urn:ietf:params:xml:ns:netconf:base:1.0">
    <capabilities>
        <capability>urn:ietf:params:netconf:base:1.0</capability>
    </capabilities>
</hello>
]]>]]>

This initializes netconf session silently. No response from Honeycomb will be provided

Next step is to get all the configuration data from VPP using Honeycomb's netconf northbound interface. Following content must be copy&pasted into SSH session + hit enter:

<rpc xmlns="urn:ietf:params:xml:ns:netconf:base:1.0" message-id="101">
    <get-config>
        <source>
            <running/>
        </source>
    </get-config>
</rpc>
]]>]]>

Honeycomb will respond will all the data currently configured in Honeycomb + VPP

Next step is to get all the operational data from VPP using Honeycomb's netconf northbound interface. Following content must be copy&pasted into SSH session + hit enter:

<rpc xmlns="urn:ietf:params:xml:ns:netconf:base:1.0" message-id="101">
    <get/>
</rpc>
]]>]]>


Honeycomb will respond will all operational data present in VPP

Using RESTCONF northbound

Testing over RESTCONF is easier, and common calls can be found in this postman collection: Honeycomb POSTMAN collection

To use:

Troubleshooting

Common issues

Unable to open SSH session

If following warning is shown when invoking ssh command: WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!. Just invoke (as suggested by the warning):

 ssh-keygen -f ...

Honeycomb fails to start properly

First thing to do is to take a look at Honeycomb logs(data/log/karaf.log).

If following log message is present: VPP-ERROR: VPP api client connection failed java.io.IOException: Connection returned error -1. Make sure VPP is installed in the system and it's running.

Note: If the VPP-ERROR also contains message stating vpp japi out of sync. It indicates incompatible versions of VPP and Honeycomb.

Honeycomb does not respond

Check suggestions from previous item: Honeycomb fails to start properly
