Graphs show data collected by Pandora FMS during a time threshold defined by the user. Pandora FMS graphs show data on request, and they are generated every time the operator requires one of them, showing the most recent data.
Pandora FMS simplifies monitoring management through user permissions. There are several permission systems that restrict what a user can see or manage, the most important is the concept of groups (either predefined groups by Pandora FMS and/or customized groups) combined with the profile of each user. Pay special attention to the notes about the “All group” (ALL
) throughout the documentation.
The graphs in Pandora represent the values that a module has had over a period of time.
Advantages: They are generated very quickly, without hardly consuming any resources.
Disadvantages: The information provided is approximate. The states of the monitors they represent are calculated based on events.
Advantages: The data represented are all decompressed data from the database. It is the most realistic way to review module data.
Module graphs represent data reported by specific modules.
They may be interactive or static graphs (by placing the mouse at some point on the backside of the graph, the specific data of that point will be shown).
Module graphs are accessible through the module detail Operation → Monitoring → Views → Monitor detail. Select the parameters to filter or leave the default ones and click Show.
In order to have access to filter management, the user must have a AW profile assigned.
Each item, depending on the data type of each module, has two icons to display graphs:
You may also find them in the agent view (module list). To access these graphs, choose an agent from Operation → Monitoring → Views → Agents Detail. To access the agent's operation menu, click on the agent's name.
To customize the module data to be displayed, click on the graph icon and then Graph configuration menu. Enabling Show AVG/MAX/MIN data series in graph will show the map key with the statistical data (Last value, Average, Maximum and Minimum) for each of the series shown.
To select an area of the graph that you want to represent, select that area with the mouse in the graph below, zooming in the desired area.You may use the right icon Overview Graph to have both graphs at the same time and click Cancel zoom to reset.
Always keep in mind that the date and time of the computer where you are running the web browser to access the Console is the one that provides the date and time for the corresponding parameters.
Once the values have been changed, click Reload to apply them.
Interface graphs are specialized combined graphs that allow to analyze the performance of a network interface.
They are automatically shown whenever the following modules exist in the agent:
interface_ifOperStatus
interface_ifInOctets
interface_ifOutOctets
Input and output octets may also appear as your HC alternatives (ifHCInOctects
, ifHCOutOctects
). When the system detects the existence of these modules, it will automatically generate the interface analysis section and the following graphs. These graphs also enable quick option selection, as in module graphs, with the particularity that they add to same view information from different sources (input and output octets) and the variety of drawing options is smaller.
Custom graphs allow to combine information from multiple modules into a single, size-variable graph. That way, information from several sources can be compared visually.
To add a combined graph, go to Operation → Reporting → Custom graphs → Create graph.
When exporting graphics in CSV format, it is important to bear in mind the decimal separator configuration of the CSV file management program to be used. Pandora FMS uses a dot as a separator by default.
To add new modules, click on the Graph Editor button, you will be presented with a form where you can add new modules from any agent. The weight option allows to adjust the data in order to compare graphs of different magnitudes. This field multiplies the data by the defined weight.
There is no limit on the number of elements to display, however the default limit (in terms of the number of modules) is 10 and can be modified in “Number of elements in custom graph”.
To see a combined graph, go to Operating → Reporting → Custom Graph where a list of all saved graphs appears. To see a graph, click on its name. When accessing the graph, it will be made up by the most recent values for the selected time threshold.
From this page, it is possible to modify certain display parameters such as time period, graph type and zoom (Graph definition, Zoom x1, Zoom x2 and Zoom x3).
To delete a stored combined graph, click on Operation → Reporting → Custom Graphs. It is where all stored graphs are listed. Click on the trash icon on the graph's right side to delete it.
The Graph container allows:
To create a graph container, access the container tab from the main custom graphs page (menu Operation → Reporting → Custom graphs → Graphs container icon). Click on Create container:
Simple module graph
Select the agent and module to be drawn, as well as the time threshold, in addition to the following options:
Custom graph
Similar to the previous graph, it allows to select an existing custom graph.
Simple module graphs based on dynamic rules
It allows you to add several simple module graphs using selectors based on regular expressions.
Specify the regular expressions that agents and modules must meet to be added to the list of graphs to generate.
At the bottom of the container's editing page, you may see the list of graphs registered in this container. You can delete them by clicking on the trash can icon.
It is not possible to edit container graphics, you must create it again with the required modifications and then remove it.
From the Containers tab, access the list of containers and their graphs. To view the graphs stored in a container, click on the container title. If there are nested containers, they will also be displayed in this tab.
There are two ways to display graphs in real time. On the one hand, there is a series of checks generated by Pandora FMS and others generated by SNMP modules.
The first to be discussed is graphs created by Pandora FMS. Therefore, go to Operation → Monitoring → Views → Real-time graphs.
Once SNMP data about the machine are entered: IP, community and OID, it will show in real time the data returned by the machine to which you are making the request. In this type of graphs, only versions 1, 2 and 2c can be checked. In order to know the OID, there is the SNMP walk tool with which you can see in tree form the OID of the machine to which you point. To learn more about SNMP monitoring, go to the following link.
Besides choosing the type of graph to use, select the graphic update interval (which minimally affects the performance) and if you wish to show the data incrementally or not. If you use the incremental, you will see a rate of the changes made in the results per second (if the interval is 1 second). It is important to emphasize that it is not possible to generate new graphs apart from those that come by default in Pandora FMS.
Another graph type is SNMP version 3 available both in in Monitoring → Views → Monitor Detail as well as within the view the agent view.
These graphs are the same as those generated in SNMP Interface throughput explained above, with the data added to the module.
Operation → Reporting → Graph analytics menu.
Graph analytics in Pandora FMS lets you quickly display one or more modules as graphs, with data from the last 12 hours by default, save this selection and even share it with a public link.
The selection box collapses once the module(s) have been selected or a saved selection has been chosen.
In the first search column, when typing in one or more characters, the matching agents, groups or modules will be searched. It should be noted that, depending on the number of agents, groups and modules in the environment, it will take some time to display the results.
By clicking on a single agent or a single group (it may take some time for groups) the second column will show the modules of the agent or group. At the same time, the second column can also be filtered by typing one or more characters.
From both lists of modules you may drag and drop them into the third column, below the default period (12 hours), for example:
Up to two modules can be placed in the same graph for comparison, and as many modules as necessary can be added for the filter.
