This topic describes how to use Pivotal Cloud Foundry (PCF) Healthwatch.

##<a id='access'></a>Accessing PCF Healthwatch

You can access PCF Healthwathch and its data through the UI or directly through the metrics datastore.

###<a id='ui'></a>Access the PCF Healthwatch UI

1. Navigate to `platform-monitoring.SYSTEM-DOMAIN`.
2. When prompted to log in, enter the username and password of the UAA user you created in [Configure UAA Authorities](installing.html#uaa-authorities).

<p class="note"><strong>Note</strong>: Currently, only the Google Chrome browser is supported.</p>

###<a id='mysql'></a>Access Data Through MySQL

You can access PCF Healthwatch data through MySQL, which is used to store product metrics. See the description of [available data points](metrics.html).

The table below provides login information.

<table class="nice">
<tr>
  <td>URL</td>
  <td>Any of the MySQL VM IPs</td>
</tr>
<tr>
  <td>Port</td>
  <td>3306</td>
</tr>
<tr>
  <td>Username</td>
  <td>MySQL Admin Password credentials in the PCF Healthwatch tile</td>
</tr>
<tr>
  <td>Password</td>
  <td>MySQL Admin Password credentials in the PCF Healthwatch tile</td>
</tr>
<tr>
  <td>Database</td>
  <td><code>platform_monitoring</code></td>
</tr>
<tr>
  <td>Tables</td>
  <td><code>value_metric</code>, <code>counter_event</code>, and <code>super_value_metric</code></td>
</tr>
</table>

To access MySQL, you can do the following:

* **Method 1**. Use BOSH to SSH into any of the MySQL VMs and run the `mysql -u root -p` command.

* **Method 2**. Assign an external IP to a MySQL VM and a firewall rule to open ports 3306 and 3308 and access MySQL externally.

* **Method 3**. Open a tunnel into your IaaS network and connect that way externally.

##<a id='scaling'></a>Scaling PCF Healthwatch Resources

Use the following guidelines to scale PCF Healthwatch resources:

* **BOSH Director Health Check** (the `bosh-health-check` app).
  Only 1 BOSH Director Health Check can run at a time. This should be considered a hard limit.
* **BOSH Deployment Task Check** (the `bosh-task-check` app).
  By default, this is scaled to 2. It is recommended not to exceed 3 runners at once.
* **CLI Command Health Check** (the `cf-health-check` app).
  By default, this is scaled to 2. It is recommended not to exceed 3 runners at once.
* **Apps Manager Uptime and Response Check** (the `appsmanager-health-check` app).
  By default, this is scaled to 2. It is recommended not to exceed 3 runners at once.
* **Ops Manager Uptime Check** (the `opsmanager-health-check` app).
  By default, this is scaled to 2. It is recommended not to exceed 3 runners at once.
