The Citrix Subnets histogram (**ANALYZE > Citrix > Histograms > Subnets**) gives you an overview of the [Citrix Performance Measurement](/performanceguard/i-want-to-know/i-want-to-know-if-citrix-works-ok/citrix-performance-measurement/) session activity on your subnets.

1. Select required **Citrix server**.
2. Select required subnet.
3. In the **Primary Type** menu, select the data set that you want to cover in the graph.

   - **Latency**: The average Citrix latency, measured in milliseconds.
   - **Max. Active Sessions**: The maximum number of active Citrix sessions.
   - **Avg. Active Sessions**: The average number of active Citrix sessions.
4. The histogram will include a top-x list of subnets. For example, if you selected Latency in the previous step, the histogram will include a list of the subnets that experienced the most latency. In the **Top X** field, select how many subnets you want such a list to cover, for example a top 10 list.
5. Select the required **Interval** (that is the period of time that you want to cover). If the predefined intervals don't suit you, select **Custom** to [Custom Time Periods on Graphs](/performanceguard/analyze/custom-time-periods-on-graphs/).
6. Click the **Update** button.
