State
The State page of the document is mainly designed to be used for focusing on hosts states monitoring, where you can easily detect any problematic situations just in time. You can open it by clicking the State Summary button on the navigation panel of the document.
State Summary
State Summary displays the actual states of hosts. It shows only those hosts the monitoring is currently active for. It is organized with the help of tiles representing the objects being monitored, that are colored to indicate of the hosts states. Let us take a closer look at the data representation.
The first mode of the State Summary is the per-host state monitoring Pic 1. This is the default mode, where each tile in the view represents a single host that is currently monitored and is colored with the host state color: green – for up, red – for down, and gray – for pending. In case the host is currently unreachable, thus the state is represented with the latest reachable one, the tile is hatched.
Together with the state, for each host you can find out how long has the host been in this state, the group the host is located in, the host IP address and resolved reverse name. All these information is available in the tool-tip and on the tile itself, when the large tiles are used. For medium tiles, you can see the host name and label on the tile together with the state time stamp. The small tiles are simply filled with the host state color; any information is available in the tool-tip only.
Along with per-host state monitoring, it is possible to monitor state for host groups. The group tile can either represent the group or the set of individual hosts (selected individually or not belonging to any group) Pic 2. The group tile is displaying the number of hosts within the group that are currently in specific states. When monitoring state in grouped mode, you can click on the group to focus on hosts from that group, or click on the specific state part within a group to focus on hosts with that specific state.
Tiles representation of host state us useful for control rooms where all hosts are displayed on a screen. In other cases you may need to use a table representation Pic 3. It shows host names, host states, state duration and other useful information as table columns.
You can switch between different modes of the State Summary page using the corresponding buttons on the view toolbar.

|
Hosts The Hosts button is used to configure the view for monitoring each host individually. |
|
Groups The Groups button is used to configure the view for monitoring groups of hosts. |
|
Group by Severity The Group by Severity button allows you to group the view the way that the problematic nodes are always displayed on top. |
|
Sort by Name When monitoring hosts, the Sort by Name button enables the view sorting by entry name. |
|
Sort by Time When monitoring hosts, the Sort by Time button enables the view sorting by state change time stamp. |
|
Focus on Problems The Focus on Problems button allows you to configure the view to be automatically scrolled to entries that go down, when grouped by severity and sorted by time. |
|
Highlight The Highlight button from the Statistics view toolbar enables and disables highlighting the performance cell and cells in the statistics table that affect the performance with the performance mark color. |

Small The Small button switches the view to the mode where each monitored host is represented just with a pictogram describing its state. Any other information on the entry is available in the tool tip only. |
|
Medium The Medium button is used to switch to the mode where each entry is represented with a tile containing only the summary information on the entry. The detailed info is available in the tool tip. |
|
Large The Large button enables the view mode where a tile representing each entry contains maximum information on the entry being monitored. |
|
Full Expand The Full Expand button is available in the table mode only. It expands all grouping nodes, if grouping is turned on for the table. |
|
Full Collapse The Full Collapse button is available in the table mode only. It collapses all grouping nodes, if grouping is turned on for the table. |
|
Group By Box The Group by Box button is available in the table mode only. It enables data grouping in the table by the values of the selected columns. When this option is enabled you can drag & drop a column to the appeared area to group data by values of this column. |

All entries within State Summary can be grouped by severity so that the problematic entries are always on top. To enable such grouping, use the Group by Severity button on the toolbar. For example, when enabled, the hosts, that are in the down state, will be displayed on top, then hosts that are in the up state will follow and then there will be the hosts with the pending state.
The Filter Editor button allows you to filter out entries with specific state. To switch between tiles of different size, use the Small, Medium and Large buttons. You can switch to the table data representation using the Table button.
Host State
On the State Summary page you can click on a host to navigate to the host details. It allows you to review the detailed information for a single host Pic 4.
On the host state page, in the left top corner you can find the block that is quite similar to the large tile representing the host and contains the same information. Below this block, you can view the information on the distribution for the twenty latest packets. To the right those latest packets are displayed in the chronological order as well as the host state that is reached after each response.
On the bottom on the page you can find the area with recent state intervals. It is used to display the most recent intervals that occurred during the last hour.
