Citrix Servers Histogram

The Citrix Servers histogram (ANALYZE > Citrix > Histograms > Servers) gives you an overview of all your Citrix Performance Measurement servers, or a group of Citrix servers, with respect to things like CPU usage and number of active sessions.

  1. Select required Citrix Servers.

  2. In the Primary Type menu, select the data set that you want to cover in the graph:

    • CPU Usage, 90th Percentile: Calculates the CPU usage in the busiest 10% of the time. For example, if you look at a period of 24 hours, the CPU usage is at least this value in 2.4 hours of the period.
    • Free Memory, 10th Percentile: Calculates the amount of free memory in the busiest 10% of the time. For example, if you look at a period of 24 hours, the available memory is at most this value in 2.4 hours of the period.
    • Max. Active Sessions: The maximum number of active Citrix sessions.
    • Avg. Active Sessions: The average number of active Citrix sessions.
    • Avg. Session Startup Time: The average time it took to start the Citrix sessions.

  3. The histogram will include a top-x list of servers. For example, if you selected CPU Usage in the previous step, the histogram will include a list of the servers that used the most CPU. In the Top X field, select how many servers you want such a list to cover, for example a top 10 list.

  4. 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.

  5. Optional: Enter Y-axis Min and Max values. If you leave the fields empty, the range automatically reflects the minimum and maximum values found in the data.

  6. Click the Update button.

The histogram opens on the Servers Histogram tab.
