# Enable Scheduler Container Logs to Track Pod Placement

## Problem

There is a requirement to track down the scheduling of the pods in the PMK cluster. The pod scheduling is not logged in the container logs located at ***/var/log/containers*** by default.

## Environment

* Platform9 Managed Kubernetes - All Versions
* Kube-Scheduler

## Procedure

{% hint style="warning" %}
**Warning**

Please ensure to apply the following procedure to one master node at a time.
{% endhint %}

* Stop Hostagent and Nodeletd.

{% tabs %}
{% tab title="Bash" %}

```bash
systemctl stop pf9-{hostagent,nodeletd}
```

{% endtab %}
{% endtabs %}

* Stop Nodelet Phases.

{% tabs %}
{% tab title="Bash" %}

```bash
/opt/pf9/nodelet/nodeletd phases stop
```

{% endtab %}
{% endtabs %}

* Edit \_ \_**/opt/pf9/pf9-kube/conf/masterconfig/base/\<OS\_NAME>/master.yaml** on all the master nodes, setting the verbosity level to **"--v=8"** for the scheduler container command, e.g.

{% tabs %}
{% tab title="Bash" %}

```bash
- name: "kube-scheduler"
      image: "k8s.gcr.io/kube-scheduler:__KUBERNETES_VERSION__"
      command:
        - "kube-scheduler"
        - "--config=/srv/kubernetes/configs/kube-scheduler.yaml"
        - "--leader-elect=true"
        - "--profiling=false"
        - "--v=8"
```

{% endtab %}
{% endtabs %}

* Start Hostagent

{% tabs %}
{% tab title="Bash" %}

```bash
systemctl start pf9-hostagent
```

{% endtab %}
{% endtabs %}

* Verify the change

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

```none
ps -ef | grep -i kube-sched
```

{% endtab %}
{% endtabs %}

{% hint style="success" %}
**Success**

Once the above procedure is applied to all master nodes, the scheduler events for pod placement can be observed in the scheduler container logs.
{% endhint %}

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://platform9.com/kb/pmk/how-to/enable-scheduler-container-logs-to-track-pod-placement.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
