Get name/IP of grid master from WAPI

[#1]

Is there a call to get the name or IP address of the current grid master from a REST API call? If so, what is it?

I've looked through the grid and member object documentation but can't seem to find it. I also can't just use the IP/name that I'm accessing the WAPI from as it doesn't match the member details configured on the Infoblox appliance.

Hi,

You can get this information using the /member endpoint like below:

curl -k -u admin:infoblox "https://grid-master/wapi/v2.11/member?_return_fields%2B=vip_setting"

Sample output:

[
    {
        "_ref": "member/b25lLnZpcnR1YWxfbm9kZSQw:infoblox.localdomain",
        "config_addr_type": "IPV4",
        "host_name": "infoblox.localdomain",
        "platform": "VNIOS",
        "service_type_configuration": "ALL_V4",
        "vip_setting": {
            "address": "172.26.1.20",
            "dscp": 0,
            "gateway": "172.26.1.1",
            "primary": true,
            "subnet_mask": "255.255.255.0",
            "use_dscp": false
        }
    }
]

If you have MGMT port enabled, you can get the mgmt IP using the following API call:

curl -k -u admin:infoblox "https://grid-master/wapi/v2.11/member?_return_fields%2B=vip_setting,node_info"

Thanks and regards,

Thanks for the reply! 

I have multiple members on the grid - this looks like it returns the IP addresses for all of the members. Is there a way to tell which one of the members is currently the grid master?

Hi,

If you know the IP address of the grid master, you can send a query with that like below:

curl -k -u admin:infoblox "https://grid-master/wapi/v2.11/member?ipv4_address=172.26.1.20&_return_fields%2B=vip_setting"

Thanks for the reply! In this case I'm wondering if there's any way to retrieve the identity of the grid master without knowing its IP address or name beforehand.

Generally you need to know the gridmaster's name or IP address because that's where you need to send the HTTPS session for the WAPI call.  By default the gridmaster is the only appliance that can accept WAPI calls.  However it is possible to turn on WAPI access on other appliances.

If you're interested in finding out, in a generic way, such as for automation, you could ask for a list of all the appliances, and request the field "upgrade_group".  The active gridmaster will be the only appliance in the "Grid Master" upgrade group.

The upgrade_group field is not searchable so you would need to return all the appliances, and then parse the data to get the one you want.

The hostname is included by default.

There are potentially multiple IP addresses on any appliance.  Typically you would want the LAN1 or VIP address, which is stored in the "vip_setting" structure.

This call:

curl -k -u admin:infoblox -X GET 'https://10.100.42.6/wapi/v2.7/member?_return_fields%2b=upgrade_group,vip_setting'

would return a list like this:

[
    {
        "_ref": "member/b25lLnZpcnR1YWxfbm9kZSQw:gm.example.net",
        "config_addr_type": "BOTH",
        "host_name": "gm.example.net",
        "platform": "VNIOS",
        "service_type_configuration": "ALL_V4",
        "upgrade_group": "Grid Master",
        "vip_setting": {
            "address": "10.100.42.6",
            "dscp": 0,
            "gateway": "10.100.42.1",
            "primary": true,
            "subnet_mask": "255.255.255.0",
            "use_dscp": false
        }
    },
       {
        "_ref": "member/b25lLnZpcnR1YWxfbm9kZSQ3:gmc.example.net",
        "config_addr_type": "BOTH",
        "host_name": "gmc.example.net",
        "platform": "VNIOS",
        "service_type_configuration": "ALL_V4",
        "upgrade_group": "Default",
        "vip_setting": {
            "address": "10.100.42.7",
            "dscp": 0,
            "gateway": "10.100.42.1",
            "primary": true,
            "subnet_mask": "255.255.255.0",
            "use_dscp": false
        }
    }
]
