Settings for MID Servers which is part of MID Server Cluster for REST Message
The MID Server Cluster is supported for Rest Message call / functionality.
The MID Server criteria plays a major role in the setting of the MID Server Cluster.
- Supported Applications
- IP Ranges
- Capabilities
By default, the MID Server's criteria above are defined as "ALL" (during the setup if not Cancel).
However, there are some MID Servers that defined particular "Supported Applications, IP Ranges, Capabilities as per the requirements.
To be able for the MID Server Cluster works for REST Message, ALL MID Servers should have the same criteria defined.
Example
MID Server Cluster: "MID Cluster" have the following MID Servers with the following criteria defined:
i. MID 1
Supported Applications: ALL
IP Ranges: ALL
Capabilities: WMI, ServiceMapping, SNMP, Resolve DNS, SSH, PowerShell, REST, VMware
ii. MID 2
Supported Applications: ALL
IP Ranges: ALL
Capabilities: ALL
iii. MID 3
Supported Applications: ALL
IP Ranges: ALL
Capabilities: ALL
With the settings defined above, if MID 1 goes down, the MID Server Cluster will not use the MID 2 and MID 3 (can be check in the ECC queue transaction, where there are no queues created for the MID 2 and MID 3 as part of the REST Message call).
To resolve:
MID 1 - Capabilities should be updated to use "ALL".
OR
MID 1, MID 2 and MID 3 - Capabilities should be updated to use only "REST".
OR
MID 2 and MID 3 - Capabilities should be updated to use the same as Capabilities of MID 1.
