The data in StackState is divided into three different sets:
Kafka Topic data
With this much data to store, it is important to have the means to manage it. There is a standard 8 days data retention period set in StackState. This can be configured according to your needs using the StackState CLI or manually on each machine. Find out more about StackState data retention.
The StackState CLI needs access to the Admin API (default port 7071) to issue the command used below.
Running the StackState CLI delete command will:
Stop all necessary services.
Delete all topology and telemetry data. Note that, the Kafka topics folder needs to be deleted manually from the StackState server. The Kafka topics folder is located in
/opt/stackstate/var/lib/ and is named
# Delete all topology and telemetry datasts graph delete --all# The Kafka topics folder needs to be deleted manually from the StackState server:# /opt/stackstate/var/lib/kafka
To clear stored data in StackState running on Kubernetes, it is recommended to run a clean install.
Please note that the below instructions are valid for a single node installation type. For a two-node installation, you need to stop the service corresponding to the node. For example,
systemctl stop stackgraph for a StackGraph node.
Stop the StackState and StackGraph services:
systemctl stop stackstatesystemctl stop stackgraph
Remove the directory that holds the files:
rm -rf /opt/stackstate/var/lib/*
Start the StackState and StackGraph services:
systemctl start stackstatesystemctl start stackgraph
