Issue/stack 1979 [healthmonitor_degrade] failed to create hm with protcol type TCP or UDP-CONNECT

[ytsai-a10]

Description

Severity Level: HIGH Desciption: HM creation failed for TCP and UDP-CONNECT type

Jira Ticket

https://a10networks.atlassian.net/browse/STACK-1979

Technical Approach

It is degraded by STACK-1654, in patch of STACK-1654 didn't consider TCP and UDP-CONNECT types. So, this patch we will check url-type and url-path before using it in directory. Because TCP and UDP-CONNECT will not have these keys in directory.

                     }
             ]

Test Cases

1. create hm for TCP
2. create hm for UDP
3. create hm for HTTP with POST method
4. all hm should create correctly.

Manual Testing

openstack loadbalancer create --vip-subnet-id f25ce642-f953-4058-8c46-98fdd72fb129 --vip-address 192.168.91.56 --name vip1
openstack loadbalancer listener create --protocol TCP --protocol-port 80 --name vport1 vip1
openstack loadbalancer listener create --protocol UDP --protocol-port 53 --name vport2 vip1
openstack loadbalancer listener create --protocol HTTP --protocol-port 8080 --name vport3 vip1
openstack loadbalancer pool create --protocol TCP --lb-algorithm ROUND_ROBIN --listener vport1 --name sg1
openstack loadbalancer pool create --protocol UDP --lb-algorithm ROUND_ROBIN --listener vport2 --name sg2
openstack loadbalancer pool create --protocol HTTP --lb-algorithm ROUND_ROBIN --listener vport3 --name sg3
openstack loadbalancer healthmonitor  create --delay 7 --timeout 6 --max-retries 3 --type TCP sg1 --name hm1
openstack loadbalancer healthmonitor  create --delay 7 --timeout 6 --max-retries 3 --type UDP-CONNECT sg2 --name hm2
openstack loadbalancer healthmonitor create --delay 3 --timeout 3 --max-retries 2 --http-method POST --type HTTP  sg3 --name hm3
openstack loadbalancer healthmonitor set --max-retries 5 hm3
