About StackState Agent V2
StackState Agent V2 functions as a collector and gateway. It connects to external systems to retrieve data and pushes this to StackState.
StackState Agent V2 can be run on Linux or Windows systems or inside a Docker container. It is not necessary to deploy StackState Agent V2 on every machine to retrieve data. Each deployed StackState Agent can run multiple checks to collect data from different external systems.
StackState Agent architecture
In StackState, the StackState Agent V2 StackPack includes all the settings required to integrate with a number of external systems. Data from other external systems can be retrieved by installing additional StackPacks in StackState.
To integrate with an external system, an Agent must be deployed in a location that can connect to both the external system and StackState. An Agent check configured on the Agent can then connect to the external system to retrieve data.
StackState Agent V2 consists of up to four different processes -
cluster-agent. To run the basic Agent, the resources named below are required. These were observed running StackState Agent V2 (v2.13.0) on a c5.xlarge instance with 4 vCPU cores and 8GB RAM. They give an indication of the overhead for the most simple set up. Actual resource usage will increase based on the Agent configuration running. This can be impacted by factors such as the Agent processes that are enabled, the number and nature of checks running, whether network connection tracking and protocol inspection are enabled, and the number of Kubernetes pods from which metrics are collected on the same host as the Agent.

For the StackState SaaS product, the StackState Receiver API address will be provided on the StackState UI Agent V2 StackPack page after the StackPack has been installed.
StackState Agent requires the StackState Receiver API key to communicate with the StackState Receiver API.
For the StackState SaaS product, the StackState Receiver API key will be provided on the StackState UI Agent StackPack page after the StackPack has been installed.
