Shooter Types

Currently Monitor one supports 9 different Shooter types, all developed for a specific task. The different types available are:

Table shooter

graphics73

A Table Shooter can be used to retrieve individual SNMP fields or complete SNMP tables with a Get or Get-Next SNMP command. All retrieved data is displayed in a two- or multicolumn table structure depending on whether a GET or a GET-Next (walk) request was used.

Graph shooter

graphics76

Graph Shooters can be used to retrieve and show numeric SNMP fields in real-time graphs. The number in the upper-left corner of the Shooter icon indicates the polling interval.

If the "At runtime" keyword is used (in the Shooter definition) as the Target instance, the Graph will prompt for selecting the desired instance at runtime. This option makes it easy to zoom-in on different ports of a multi-port switch when trying to find performance bottlenecks.

graphics77

The Inst control lets you choose the instance at runtime!

If the "All Instances" keyword is used in the Shooter definition then the values of ALL instances of the OID specified as the Target are shown in one Graph! The All Instances option makes it easy to show - for example - the load of all ports of a switch in one Graph!

Graph types
The current version of Monitor one supports 4 different graph-types: an 2 dimensional line-graph, the same line-graph but with a 3 dimensional look, a bar- and an area-graph. You can select the desired graph-type by clicking one of the Graph type speedbuttons
Raw/Delta
Use the Raw Raw icon and Delta Delta iconspeedbuttons to select how to display the retrieved SNMP values. Use Raw for displaying utilization or percentage statistics. Delta displays the difference between the last retrieved values and the previous ones. Delta is usually used for showing Bytes/sec, Frames/sec etc...
Lin/Log/Automatic UpDown scaling
Use the Lin (Linear) or Log (Logarithmic) speedbuttons to set the desired y-axis scaling. If you select Options|Automatic UpDown scaling then Monitor one automatically scales the Y-axis up/down each time new data is added to the graph. In web mode Automatic UpDown scaling is always ON.
Top-20 series only
If an "All Instances" graph is shown, it might happen that there are so many series to show that the size of the graph does not fit into the window/screen. This is where the Top-20 switch is meant for! Click the Show Top-20 series only speedbutton to limit the number of displayed series to the top-20 only.
Title and Axis/Background color
Right-click somewhere on the graph and choose the desired menu-item in order to change the Title and Axis of a graph or change the background color.

Graph/Data tabs
The Graph and Data tabs speak for themselves. The Data tab lists besides the Min, Max and AVG of the retrieved values also the most recent 5 retrieved values. See the screenshot below

Graph data tab

graphics72The real-time Graph windows are available in native- as well as in web mode. In native mode, all graph settings as: graph type, colors, window size, Abs/Rel etc... are saved to the database and are restored again the next time you start the same Graph Shooter. You can also change the look and feel of the Graph window in web mode but these modifications are not saved to the database!

Threshold shooter

graphics79

A Threshold Shooter can be used to monitor numeric values and compare them with a threshold value. An event is generated if the value of the value exceeds a defined threshold.

Threshold Shooter

History shooter

graphics80

Use a History Shooter to collect and log history information from devices to the database for trending and long-term analysis purposes. Monitor one saves History information into two different databases, the native Monitor one databases and RRD databases.

RRD is the Acronym for Round Robin Database. RRD is a system to store and display time-series data (i.e. network bandwidth, machine-room temperature, server load average). It stores the data in a very compact way that will not expand over time, and it presents useful graphs by processing the data to enforce a certain data density.

RRD (and the key program, RRDTool) is a very powerful and popular system, written by Tobi Oetiker and available under the terms of the GNU General Public License. Monitor one can be used as a front end for RRD and RRDTool. More information on RRDTool can be found here: http://oss.oetiker.ch/rrdtool/

Set shooter

graphics82

A Set Shooter allows you set/write SNMP fields. You can use Set Shooters to create simple configuration forms for managing network devices.

graphics83

Meter shooter

graphics84

The AnalogMeter Shooter (also called just "Meter") can be used to show a value on an old-fashioned VDO-like meter. The Meter is especially useful to display Utilization and Usage etc. Be aware that a Meter Shooter is not able to show more than one value at a time because the Meter has only one needle!

The real-time Meter windows are available in native mode as well as in web mode. In native mode, all Meter settings as: Colors, window size, Abs/Rel etc… are saved to the database and are restored automatically the next time you use the same Meter again.

graphics72You can also change the look and feel of the Meter in web mode but these modifications are not saved to the database!

Raw/Delta
Use the Raw Raw icon and Delta Delta icon speedbuttons to select how to display the retrieved SNMP values. Use Raw for displaying utilization or percentage statistics. Delta displays the difference between the last retrieved values and the previous ones. Delta is usually used for showing Bytes/sec, Frames/sec etc...
Title, Meter appearance and Needle colors
Right-click somewhere on the Meter and choose Set Meter properties. This lets you customize the look of the Meter.

SnipMon Gauge and SnipMon Graph shooters

graphics86graphics87

SnipMon Shooters appear as small images below a device icon on the network map. They are updated in real-time and are especially useful if you want to have important or critical device information always directly at hand.

A SnipMon Gauge (a small meter) can for instance be used to display CPU- or memory utilization, temperature or used disk space.

A SnipMon Graph is very useful for displaying interface utilization, number of running processes etc over a short period in a graph. If the mouse moves over a SnipMon, detailed information such as a description of the SnipMon and the last/most recent value is shown.

graphics88

The example SnipMons above (from left to right) show: CPU utilization, interface utilization and percentage used disk space of a certain drive.

Pie Shooter

graphics89

A Pie Shooter is useful for displaying things like the Top-talkers or the Top-5 busiest ports etc. The Pie graph is available in native mode as well as in web mode. In native mode, all Pie settings as: Number of slices, colors, window size, Raw/Delta etc… are saved to the database and are restored automatically again the next time you use the same Pie Shooter.

graphics72You can also change the look and feel of the Pie window in web mode but these modifications are not saved to the database!

Raw/Delta
Use the Raw Raw icon and Delta Delta icon speedbuttons to select how to display the retrieved SNMP values. Use Raw for displaying utilization or percentage statistics. Delta displays the difference between the last retrieved values and the previous ones. Delta is usually used for showing Bytes/sec, Frames/sec etc...
#Slices
The #Slices control lets you adjust how many slices to show. For example: If you select 5 slices then the Top-4 is shown and slice #5 (labeled "Other") shows the summation of all other slices not in the top 4!
Title and Axis/Background color
Right-click somewhere on the graph and choose the desired option to customize the Title and Axis of a graph or in order to change the background color.
