# Viewing topic partitions

To view topic partitions select the Partition tab. Here you can see a heat map of messages in the topic and their distribution across the partitions.

{% hint style="info" %}
Is the map evenly distributed? If not you might have partition skew.
{% endhint %}

Further information about the partitions and replicas is displayed, for example, whether the replicas are in-sync or not.

{% hint style="info" %}
If the replicas are not in-sync an [infrastructure ](/latest/devx/5.5/user-guide/monitoring-and-alerting/infrastructure-health.md)alert will be raised.
{% endhint %}
