Guide for setting up a cluster/load balanced Cluster Active Gate configuration

runatyr — Thu, 28 Dec 2023 11:59:15 GMT

Hello:

We currently have one Cluster Active Gate that collects data from external sources as well as several DMZ environment AG's.

We are interested in making the cluster AG High Availability by having a second Cluster AG present.

Are there any guides available on how to do this? Our current Cluster AG is dual nic and the second server would also be dual nic.

Hi,

if you ask about how to set up HA for Cluster AG - you just install additional Cluster AG and that's it. However, there are certain rules you have to remember:

ActiveGates exist in the following hierarchy:

Level 1—Environment ActiveGates
Level 2—Cluster ActiveGates
Level 3—Embedded ActiveGates—ActiveGates embedded within cluster nodes

ActiveGates can only send data to higher hierarchy levels. It is impossible to send data to the same or lower level of the hierarchy.

Environment ActiveGates, by default, connect directly to the Dynatrace Cluster (unless custom network zones are used—see below). This eliminates an intermediate step of connecting to a Cluster ActiveGate. Connecting through the Cluster ActiveGate needs to be arranged if the Dynatrace Cluster is not directly reachable. For example, if the Environment ActiveGate is in a different network or different data center.

Connectivity can also depend on network zones if such are configured. Network zone configuration means that ActiveGates and OneAgents will prefer to communicate with ActiveGates from the same zone, before connecting to ActiveGates outside of the active zone.
