Simple Script output to graph

Overview:

This quickly goes over the steps needed to take the single output of a script and graph it over time.

1. Console :: Collection Methods :: Data Input Methods :: <add>

2. Name = random-script (the name of the input method)

3. input string = perl <path_cacti>/scripts/random2.pl (the location of the perl script)

4. Output Fields :: <add> script does not need any arguments, but will produce one output)

5. Field Output = random_number (define the variable name for the output)

5. Friendly Name = Random Number (a description to the variable name)

5. <save>

6. Console :: Management :: Data Sources :: <add>

7. <create>

8. Name = random2ds (name for this data source)

9. Data Input Method = random-script (select from the pulldown the data-input-method: step#1)

10 Internal Data Source Name = random_number (variable name for rrd file)

11. <save>

12. Console :: Management :: Graph Management :: <add>

12. <create> (leave two variables blank, and just select create button)

13. Title = RANDOM NUMBERS (title of the graph)

14. Vertical Label: Random Number (add a title for the graph)

15. <create>

16. Graph Items :: <add> (create a graph item)

17. Data Source = random2ds (select name of data source, step #8)

18. Color = {something} (pick a nice color for the lines of your graph)

19. Graph Item Type = line1 (this kind of graph would look best as a line)

20. <create>

Then you will see your graph being plotted.

After this, add your graph to your tree under

Console :: Management :: Graph Trees
