Stop Splunk Observability Studio

Use this skill when you need to stop the local Splunk Observability Studio or disconnect from it safely.

Ownership rules:

• managed: the current plugin started Splunk Observability Studio and may stop it.
• shared: Splunk Observability Studio is reused across repos or sessions; do not stop it

unless the current plugin explicitly owns it.

• external: Splunk Observability Studio was started outside the plugin; do not stop it.

If ownership is unclear, do not stop anything. Report the current state and recommend manual recovery instead.

Prefer the live health endpoint and listener over stale log output or an old saved PID. If health is good and the bundled Splunk Observability Studio binary is already listening, update the saved PID and stop; do not stop or kill a second copy just because the cached state is stale.

Endpoint checks are limited to the Splunk Observability Studio loopback endpoints:

• health: http://127.0.0.1:17900/api/health
• listener inspection: 127.0.0.1:17900, 127.0.0.1:4317, and

127.0.0.1:4318

Steps

1. Check whether Splunk Observability Studio is managed, shared, or external.
2. If Splunk Observability Studio MCP is configured to a non-default endpoint, report:

Splunk Observability Studio MCP is configured to a non-default endpoint: <url>. For safety, this command skill only verifies or controls the default loopback Splunk Observability Studio at 127.0.0.1:17900. I will not probe or control the custom endpoint. Use the MCP server directly, update the config back to the default local Splunk Observability Studio, or manually verify the custom Splunk Observability Studio.

1. Before probing host-local endpoints or inspecting local listeners from a

shell command, request narrow elevated/outside-sandbox permission. Do not first try the check from inside the sandbox.

1. Check only http://127.0.0.1:17900/api/health for Splunk Observability Studio health. Do not

use the MCP endpoint as a health check and do not follow alternate hosts from MCP or user config.

1. If elevated access is denied or the endpoint cannot be verified from the

available context, report sandbox-unverified; do not report Splunk Observability Studio as unhealthy based only on sandbox-local reachability.

1. If health is good and the bundled Splunk Observability Studio is already listening, update the

saved PID to match the live process, then continue applying the ownership rules below.

1. If it is shared or external, do not stop it unless the current plugin

explicitly owns it.

1. If it is managed, stop only the process that the current plugin started.
2. Record "status": "stopped" in the plugin bootstrap-state.json so the

next SessionStart hook does not restart the managed Splunk Observability Studio.

1. Confirm http://127.0.0.1:17900/api/health is no longer reachable if the

goal was to fully shut down the local runtime.
