StackState version 4.4
Overview
A number of advanced configuration options are available for StackState Agent V2. These can be set either in the stackstate.yaml configuration file (Linux and Windows) or using environment variables (Docker, Kubernetes and OpenShift).
Blacklist and inclusions
Processes reported by StackState Agent V2 can optionally be filtered using a blacklist. Using this in conjunction with inclusion rules will allow otherwise excluded processes to be included.
The blacklist is specified as a list of regex patterns. Inclusions override the blacklist patterns, these are used to include processes that consume a lot of resources. Each inclusion type specifies an amount of processes to report as the top resource using processes. For top_cpu and top_mem a threshold must first be met, meaning that a process needs to consume a higher percentage of resources than the specified threshold before it is reported.
Docker, Kubernetes, OpenShift
Linux, Windows
To specify a blacklist and/or inclusions, set the associated environment variables and restart StackState Agent V2.
Environment variable
Description
STS_PROCESS_BLACKLIST_PATTERNS
A list of regex patterns that will exclude a process if matched. Default patterns (github.com).
STS_PROCESS_BLACKLIST_INCLUSIONS_CPU_THRESHOLD
Threshold that enables the reporting of high CPU usage processes.
STS_PROCESS_BLACKLIST_INCLUSIONS_TOP_CPU
The number of processes to report that have a high CPU usage. Default 0.
STS_PROCESS_BLACKLIST_INCLUSIONS_TOP_IO_READ
The number of processes to report that have a high IO read usage. Default 0.
STS_PROCESS_BLACKLIST_INCLUSIONS_TOP_IO_WRITE
The number of processes to report that have a high IO write usage. Default 0.
STS_PROCESS_BLACKLIST_INCLUSIONS_MEM_THRESHOLD
Threshold that enables the reporting of high memory usage processes.
STS_PROCESS_BLACKLIST_INCLUSIONS_TOP_MEM
The number of processes to report that have a high memory usage. Default 0.
To specify a blacklist and/or inclusions, edit the below settings in the Agent configuration file stackstate.yaml and restart StackState Agent V2.

Disable Agent features
Certain features of the Agent can optionally be turned off if they are not needed.
Docker, Kubernetes, OpenShift
Linux, Windows
To disable a feature, set the associated environment variable and restart StackState Agent V2.
Environment variable
Description

STS_APM_ENABLED
Default true. Set to "false" to disable the APM Agent.
STS_NETWORK_TRACING_ENABLED
Default true. Set to false to disable the network tracer.
To disable a feature, edit the below settings in the Agent configuration file stackstate.yaml and restart StackState Agent V2.
Linux - /etc/stackstate-agent/stackstate.yaml
Windows - C:\ProgramData\StackState\stackstate.yaml
Configuration item
