State Monitor View

The State Monitor view, that is located within the group of views in the middle of the main program window, is mainly designed to be used for focusing on hosts states monitoring, where you can easily detect any problematic situations just in time. The view displays only those hosts the monitoring is currently active for. It is possible to monitor per-host states as well as the states distribution for groups of hosts. The view 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 view and its features.

Monitoring hosts state

Pic 1. Monitoring hosts state

The first mode of the State Monitor view we are going to introduce 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.

Monitoring state for groups of hosts

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.

You can switch between different modes of the State Monitor view using the corresponding buttons on the view toolbar.

Toolbar Overview

Hosts

Hosts

The Hosts button is used to configure the view for monitoring each host individually.

Groups

Groups

The Groups button is used to configure the view for monitoring groups of hosts.

Group by Severity

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

Sort by Name

When monitoring hosts, the Sort by Name button enables the view sorting by entry name.

Sort by Time

Sort by Time

When monitoring hosts, the Sort by Time button enables the view sorting by state change time stamp.

Focus on Problems

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.

Link to Hosts View

Link to Hosts View

The Link to Hosts View button can be used to filter the view for displaying only those items that are selected in the Hosts view.

Small

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

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

Large

The Large button enables the view mode where a tile representing each entry contains maximum information on the entry being monitored.

Filter Editor

Filter Editor

The Filter Editor button should be used to define the custom filter criteria to be applied to the monitored entries.

All entries within the State Monitor view 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 down, will be displayed on top, then hosts that are up will follow the down ones, then there will be the hosts with the pending state.

The State Monitor view can be filtered to always display information for the entries currently selected in the Hosts view. You can enable such behavior using the Link to Hosts View button. 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.

Within the State Monitor view you can also focus on monitoring specific hosts and then pin the tab with the host, if required. To monitor single host, just click the tile the host is represented with. The content of the view will be replaced with host monitoring details Pic 3.

Monitoring state for a single host

Within the detailed state monitor view, 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 detailed state monitor view you can find the area with recent connectivity events. It is used to display the fifteen most recent events about state changes that occurred during the last hour.

Within the view header, next to the host name and group, the arrow is located that allows you to go back to per-host state monitoring. The header also contains the buttons that allow to print and save the report based on the displayed monitoring data and pin the current detailed monitor. When pinned, a new tab is created representing the detailed monitor for that host. So you can open several detailed monitoring tabs next to each other.
