Statistics View
The Statistics view Pic 1 is by default located within the group of views in the middle of the main program window and displays the monitoring statistics for specific periods of time. The view can either display the summary statistics for multiple hosts or detailed monitoring statistics for specific host. Let us take a close look at each of the modes.
Statistics Summary
The monitoring statistics summary is represented in a form of a table Pic 1 where each row stands for a single host. The statistics is displayed for the period chosen on the view toolbar. You can choose between live intervals, which are configured on the Monitoring Statistics preference page, a set of predefined historical intervals and custom historical interval. You can apply grouping, sorting and filtering operations for all available hosts at once.
Along with the statistical values, in the Statistics view you can find the performance characteristics, calculated on a basis of these values. The conditions for calculating the performance are provided on the Performance preference page. By default, the performance values are highlighted due to their severity, as well as the values that affect the performance. This behavior is controlled with the Highlight button on the toolbar.
Please note that not all of the available data columns are displayed in this view by default, but you can always choose the columns you really need and remove the unwanted ones by using the column chooser. For example, you can display the Uptime Interval and Downtime Interval columns to see how exactly the uptime percentage was calculated.
For the statistics table, you can choose from the following set of columns.

To reach the detailed statistics mode from the Statistics view, you can either click the host name hyper-link in the summary table or choose the Show Details item from the pop-up menu of the host. It is also possible to jump to the detailed monitoring statistics of the host, when selecting it in the Hosts and Connectivity Events views via the Show Statistics > Details menu.
The detailed statistics view for a single host Pic 2 consists of the common host information displayed on the top of the view and six tabs, those are: Overview, Latency & Uptime, State & Quality, State Intervals, Quality Intervals and Events. Let us take a closer look on each part of the view.
The common host information consist of the host name, label and group the host is located in. On the right side of the common info, you can find the buttons for selecting statistics display period, opening the detailed timeline, exporting raw data and publishing the statistics report. In case if you are viewing host details in a not pinned window, you'll also find the pin button, that will either propose you to pin or to unpin details for the current host. When pinned, the new tab is created with the statistics for the host, thus you can view detailed statistics for multiple hosts in parallel.

The host address part of the common host information pane is clickable. The click on this part will open the corresponding host for editing. As we are done with the common part, let us move over to the categorized pages.
The Overview page Pic 2 is used to provide you with the integral monitoring statistics gathered during the specified period, graphically visualized and grouped by categories. The information on this page is grouped in several categories. In the left top corner, you can find the performance characteristics. Below the performance characteristics, you can find the information on host availability during the specified interval. It consists of an uptime percentage, uptime and downtime intervals, a packet loss percentage, lost and delivered packets counts and outages information. The next category to follow is the information on latency: minimum, maximum, average, deviation and coefficient of variation. The next category is showing you the percentage and intervals of different connection quality during the specified period. The last within the left column comes the category, displaying information on monitoring activity – you can find the activity time interval and pause time interval. On the right side of the Overview page the two statistics analysis charts are located. In the top chart you can find the latency and uptime analytic, and the bottom chart displays the analysis information for state and quality intervals. You can click on the points in both charts to open the detailed timeline for the period the point displays integral data for.
The Tracking page Pic 3 is aimed to display the real-time chart with latest responses along with latest state and quality changes. This information is displayed only when reviewing live statistics and, in case the selected interval is longer than an hour, only the data for the latest hour is displayed due to performance reasons.
The Latency & Uptime page Pic 4 is used to focus on the latency and uptime analysis. The chart similar to the one on the Overview page is displayed, but occupies the entire area, so you can review the points in a more detailed manner. The level of aggregaion in the chart is adjusted automatically for the specified period.
|
Export The Export button from the Latency & Uptime page toolbar allows you to export the data used for building the displayed analysis chart to a CSV format. |
If required, you can export the data used for building the displayed analysis chart using the Export button on the toolbar.
The State & Quality page Pic 5 is used to focus on the host state and connection quality intervals distribution analysis. The displayed chart is the same as the one on the Overview page, but occupies the entire area, so you can review the bars in a more detailed manner. The level of aggregaion in the chart is adjusted automatically for the specified period.
|
Export The Export button from the State & Quality page toolbar allows you to export the data used for building the displayed analysis chart to a CSV format. |
If required, you can export the intervals distribution analysis data displayed within the chart using the Export button on the toolbar.
The State Intervals and Quality Intervals tabs are quite similar. The first one displays the list of all host state intervals for the selected period of time, and the second one – the list of connection quality intervals. Let us take a closer look at these pages using the State Intervals one as the reference Pic 6. The list of intervals is displayed in a form of a tree, where the root nodes represent the specific state. In case the host has been unreachable during any interval, it can be expanded to review when the host was reachable and when not. In case the comment is provided for the interval, it is displayed under the root node. For each interval, along with its type, you can find the start time, end time and duration. In case the interval is exceeding the selected period, the exceeding time is marked with a star.
|
Export The Export button from the toolbar allows you to export the displayed intervals list to a CSV format. |
|
Edit Comment The Edit Comment button can be used to provide a comment for the selected interval. |
|
Full Expand The Full Expand button from the toolbar should be used to expand all nodes in the intervals tree. |
|

|
Filter Editor The Filter Editor button should be used to define the custom filter criteria to be applied to the data displayed in the intervals tree. |
|
Advanced Options The Advanced Options button from the toolbar opens the view configuration menu where you can reset the layout of the view. |
For each state or quality interval, it is possible to provide a comment. The comment can, for example, describe the reason for the outage, or something else. To provide a comment, select the interval and choose the Edit Comment item in the pop-up menu or click the corresponding button on the toolbar. The dialog will be displayed on the screen to let you provide the comment. Either the selected or all intervals can be exported to a CSV file using the Export button on the toolbar and the Export All and Export Selected menu items. At any point, you can reset the view layout to defaults using the Reset Layout option from the Advanced Options menu.
The last page is the Events one. It contains all monitoring and connectivity events for the host and can be used as a monitoring log. If you are facing some problems during monitoring or would like to know when the monitoring process was started and stopped, you should refer to this page. The important connectivity events for each host are also available in the Connectivity Events view.
The events are displayed in a form of a table where each row represents a single event. You can sort, group and filter the events by any column as well as change the columns set. By default the table consists of the event type represented by an icon, the event title, the logging time and the event description itself, with or without a troubleshooting hint. The description and hint for any event is by default wrapped, so that you can easily read it. If you would like to have more events visible at the same time, you can configure the Events page to display only one line per event by disabling the Wrap Description option from the Advanced Options menu. If required, it is possible to add the Error Code column to the view using the Column Chooser.
The following icons are used to display the event types:
|
- |
the blue icon with an 'i' character means that everything is OK; |
|
- |
the brown circle icon with a cross-cut line is used to identify that the operation was canceled by user or due to shutdown of the underlying system; |
|
- |
the yellow icon with an exclamation mark is the warning icon. It means that the special attention should be payed to this event; |
|
- |
the red icon with a white cross is the error sign: it stands for a failure event. |
If required, you can add a column containing the text representation for the severity, that can be used for grouping and filtering data.

You can open the timeline using the Timeline button in the detailed statistics view. You can focus on specific interval of the timeline by clicking the point within Latency & Uptime or State & Quality charts.
Within the Timeline dialog Pic 8, you can find the timeline graph and the sliders to be used for navigation through the timeline. The timeline graph consists of three parts, those are Latency, State and Quality. The Latency part is used to display the ping replies data, the State part reflects the state intervals on the timeline and the Quality part is used for displaying the quality intervals.
