# Killing pf9-hostd Process Restarts Platform9's Host Agent Service

## Problem

There is a need to temporarily kill the *pf9-hostd* process on one of the hypervisors.

{% tabs %}
{% tab title="None" %}

```none
pf9 4024 4022 0 Jul26 ? 09:25:29 /opt/pf9/hostagent/bin/python /opt/pf9/hostagent/bin/pf9-hostd
```

{% endtab %}
{% endtabs %}

How would the hypervisor be affected?

## Environment

* Platform9 Managed OpenStack - All Versions

## Answer

1. Killing the *pf9-hostd* process will essentially restart the *pf9-hostagent*(Platform9's Host Agent Service) service. It will not affect any running instances on the host.
2. The host however would be seen to be in a converging state to the management plane when the service does restart.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://platform9.com/kb/pmo/how-to/killing-pf9-hostd-process-restarts-platform9s-host-agent-service.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
