Working with Graphs
- Alon Men
ZEN Master features a wide variety of graphs that allow you to monitor the resources, objects, and networks over time. In most cases, the data is gathered from the underlying resource/object (e.g., Broadcaster, ZEC, etc.) and displayed in the relevant graph format and units/scales.
Understanding the legends
Most graphs display multiple measurements in a single graph to provide multiple perspectives and help in the troubleshooting process. Each measurement and its related color appears in the legend, which is located underneath the corresponding Y-axis. The Y-axis adjusts to accommodate the min and max values of the entire displayed graph, expanding or contracting to show as much detail as possible for the given range.
For example, the following graph measures the CPU (green) and Memory (yellow) utilization. Both legends are located underneath the Y-axis on the left as they share the same unit scale, which in this case is the percentage. Â The X-axis refers to the timescale of the graph, with the right-hand edge being the current point in time, left of which the data progresses further into the past.
In the following example, there are two sets of legends. The left legend corresponds to the unit scale on the left Y-axis and the right legend corresponds to the unit scale on the right Y-axis.
Viewing the measurement details
To view the exact measurement details of a graph at any point in time, hover your mouse over the graph at the desired point in time.
Changing the time range
There are multiple ways to change the timescale displayed on the graph:
Entering an absolute time range
Selecting a relative time rangeÂ
Navigating back/forward across the time range
Zooming in to a selected range
Zooming out
Changing the time range by entering an absolute time range
To change the time range by entering an absolute time range:
Click the Time Range field.
Under the Absolute time range section click the From field or enter an exact date and time in the following format – YYYY-MM-DD HH:MM.
Select the beginning of the time range, by double-clicking the desired day in the calendar.
Optionally edit the time in the following format - HH:MM:SS.
Click the To field and repeat the process.
Click Apply time range.
The graphs will be updated with graphs from the selected time range.
Selecting a relative time range
To select a relative time range:
Click the Time Range field.
Under the Relative time range section, click on one of the relative time ranges from the list.
The graphs will be updated with graphs from the selected time range.Â
Navigating back/forth across the time range
To navigate back and forth in time:
Click the Time Range Zoom Out button.
Click the right/left arrow to move forward/backward in time at the same time interval as the selected time range.
Â
Zooming in to a selected range
To focus on a specific time range within the graph, select the time range using your mouse.
Â
The graph displays the selected time range and the specific time range is displayed in the time range filter.
Zooming out
To zoom out in the time range, click the Time Range Zoom Out button.
Changing the time zone
By default, the graph uses your browser’s local time zone, however it is possible to change the timezone. The time zone is indicated in the Browser Time field.
To change the timezone:
Click the Time Range field.
Click Change Time Zone.
Select the relevant timezone from the drop-down list. You can search it by typing the name of the country, city, or the timezone abbreviation.
Refreshing the graph
The data presented in the graphs does not refresh on its own (i.e., it displays data up to the moment the graph has been displayed). It is possible to refresh the data manually or automatically at predefined time intervals.
To manually refresh the graph:
Click the Refresh button.
To set an automatic refresh time interval:
Click the dropdown menu next to the Refresh button.
Select the relevant refresh time interval from the list.
