# cfxdm - dm:tail

**dm:tail:** This cfxdm tag allows the user to fetch last 'n' rows from the queried data.

**dm:tail** syntax**:** 

* **n (optional)**. Specify number of last rows that need to be listed. When this argument is not specified, by default it retrieves last 10 rows.

{% hint style="info" %}
For predictable results, use it along with **dm:sort** tag.
{% endhint %}

In the below example, for a reference, we are going to use **VMware vROps** as an extension to query the data and ingest it into **dm:tail** tag to list last 'n' rows.

Enter the below command to select **VMware vROps Datastore Summary tag (\*vrops:datastore\_summary**). (In this example, vrops name is used as a label to identify VMware vROps extension and it's tags. The label is defined while adding the extension in cfxdx configuration file or through UI)

```
tag *vrops:datastore_summary
```

```

**Example 2:** Sort the data in ascending order and List last 20 rows.

Get the data from VMware vROps Datastore Summary tag (**\*vrops:datastore\_summary**), sort the data by datastore name and list last 20 rows.

```
data --> dm:sort columns = 'name' --> dm:tail n = 20
```
