The QoS report is intended to provide an overview of the Qality Quality of Service configuration and utilisation of the selected nodes.Rules
To assist in the assimilation of the data, a few simple rules have been applied to the statistics to assist with highlighting some possible problem areas.
Queue Drop
This condition indicates that a QoS Policy is being exceeded and packets in this class have been dropped. It may or may not be impacting applications, depending on how they handle packet loss. For example, HTTP will generally handle packet loss with no problems, while voice and video do not suffer packet loss very well at all.
If an interface utilisation is greater than 0% input and 0% output;
AND DropPkt is greater than 1 packet per second;
THEN this class is highlighted yellow.

...
Class Utilisation Exceeding Policy
This condition indicates that QoS class was configured for a certain bandwidth and the traffic levels have exceeded the configured policy. This may not be a problem, depending on QoS configuration, traffic may be being forwarded or discarded, if necessary increase the bandwidth allocated to this class.
If an interface utilisation is greater than 0% input and 0% output;
AND PrePolicyUtil exceeds the classes configured bandwidth Percent;
THEN this class is highlighted yellow.
Uptime Report
The uptime repors provides an overview of recently restarted devices, as well as very long running ones.
The configuration items uptime_shortest_days (default 7) and uptime_longest_days (default:365) define which nodes should be selected for display.

...
Response Time Report
The Response Time report tabulates the selected nodes in descending order of their average response time. Besides the average and maximum measurements, the report also shows the 95th percentile of the response time. These readings are in milliseconds.
...
This column shows the number of times a device's response time has exceeded the exception threshold during the reporting period. This threshold is configurable (property response_exception_threshold), and its default value is 10 ms.

Interface Utilisation Report
...
- Option
show_threshold(default: true)
If set to false, no thresholds are shown; instead the bandwidth, average traffic and average utilisation are presented (plus a shortened report period column). - Option
show_only_util(default: false)
Ifshow_tresholdis false, and ifshow_only_utilis set to true, then only bandwidth and average utilisation are shown (ie. average traffic is omitted).

CPU Report
This report shows the average CPU utilisation for Cisco devices, for both 1-minute and 5-minute averages.

Free Memory Report
This report shows the free memory statistics for Cisco devices.

Memory Pool Report
This report shows the memory pool statistics for Cisco devices.
More information can be found here: Memory Pool Report
Traffic Usage Report
This report displays the cumulative traffic usage figures for one or more interfaces. The measurements that are displayed include the node and the interface, and total traffic inbound, outbound and combined (all in Gigabyptes), plus a shortened report period column.

Traffic Summary Report
The traffic summary report provides a specialized report of categorized and grouped traffic figures for any number of nodes and interfaces.
This report requires a node_intf_type input file that provides nodes, interfaces and "type" for grouping (see How to select Nodes (and Interfaces) for reporting).
The interfaces are grouped both by their "type" attribute and their average combined utilisation (into categories Low=<45%, Minor=<80%, and Major=>80%).
The report consists of
- A summary table, which displays for each "type" category the number of interfaces in each utilisation category (and a total)
- And a details table for each combination of "type" and utilisation categories.
The details table shows the node and interface, the input and output interface speeds, the average combined traffic and the average combined utilisation, plus a shortened period column.
For output formats HTML and CSV these tables are shown one after the other. For XLSX, the tables are put on separate worksheets (within a single spreadsheet file).

Node Availability Report
New in version 3.0.8. Please note that the precise content of this report is subject to change.
This report provides an overview of nodes' reachability and down time for a given period (which may include business days and/or business hours filtering).
For each selected node the report shows the percentage of time the node was up, down, or partially reachable (i.e. up but packet loss was encountered), plus the percentage of time where NMIS couldn't collect any reachability information whatsoever, as well as the cumulative periods for up, down and periods with missing data.
From version 3.0.10 on this report offers optional embedded graphs of each node's availability. The default choice is to include graphs but you can change that using the report option embedgraphs. In the GUI this option is named "Include Embedded Graphs". The contents of the graph are not configurable, but the desired size can be set using the configuration option opreports_embedded_graph_size (default: 600 pixels wide by 150 pixels high).

Interface Capacity Report
New in version 3.0.8. Please note that the precise content of this report is subject to change.
The interface capacity report displays a comparison between configured interface speeds and observed actual bandwidth figures.
For each selected interface, it shows the configured input and output speeds, the observed maxima of input and output bandwidth for the report period, and the 95th percentile of the interface utilisation.
Before version 3.0.14, the 95th percentile for combined interface utilisation was shown (Combined utilisation in this report means the set of averages of each input and output utilisation reading). From 3.0.14 onwards, you can select from three options: the 95th of combined utilisation, two separate columns for 95th of inpunt and output utilisation, or three separate columns for 95th of input, output and combined utilisation.
From version 3.0.10 on this report offers optional embedded graphs of each interface's capacity. These graphs show the observed input and output bandwidth (input in green, output in blue), and the higher of the configured in and out speeds as a red warning line. If the configured input and output speeds are identical, the 95th percentile of the combined interface utilisation is also shown as a dotted line.
The default choice is to include graphs but you can change that using the report option embedgraphs. In the GUI this option is named "Include Embedded Graphs". The graph contents are not configurable, but the graph size can be adjusted using the configuration option opreports_embedded_graph_size (default: 600 x 150 pixels).

Traffic Snapshot Report
New in version 3.0.14.
The snapshot report type produces a table of interface utilisation versus interface capacity for one or more groups of interfaces, with configurable coloring of the utilisation column. The utilisation data is computed and presented for each group of interfaces. Besides that, for each interface a (selectable) NMIS graph is included as well.
The groups of Interfaces are selected exclusively from opCharts Business Service definitions, hence opCharts is required to be installed on the same machine for this report type.
The report type is somewhat geared towards XLSX outputs, and supports multiple pages where each page definition contains its own list of sources, coloring rules, measurement and graph options; each page definition results in a separate XLSX worksheet. For the CSV output type, only the utilisation tables are present. In HTML output, all the logical pages are included on one HTML page, but visually separate in their own sections.
The snapshot report produces tables of interface utilisation versus interface capacity for one or more groups of nodes and interfaces, with configurable coloring rules for each group (based on utilisation ratio). For each interface a (selectable) NMIS graph is embedded as well.
