Behavior

• The Toolkit plug-in executes scripts asynchronously.
• The Toolkit plug-in is executed by the Netprobe on a separate thread.

Asynchronous Logic

Example A

Scenario

• Sample interval is 10 seconds
• Script finishes after 5 seconds

Event

@01:00:00

• 1st sample
• Toolkit sampler executes the script

@01:00:05 - Toolkit sampler sends the update to the Gateway. Toolkit dataview gets updated.

@01:00:10

• 2nd sample
• Toolkit sampler checks the status of the script;
  • If the script is done, the sampler executes the script again. (This is what happens during this sample.)
  • If the script is not yet done, the sampler the sampler does not do anything.

Example B

Scenario

• Sample interval is 10 seconds
• Script finishes after 15 seconds

Event

@01:00:00

• 1st sample
• Toolkit sampler executes the script

@01:00:10

• 2nd sample
• Toolkit sampler checks the status of the script;
  • If the script is done, the sampler executes the script again.
  • If the script is not yet done, the sampler does not do anything. (This is what happens during this sample.)

@01:00:15 - Toolkit sampler sends the update to the Gateway. Toolkit dataview gets updated.

@01:00:20

• 3rd sample
• Toolkit sampler checks the status of the script;
  • If the script is done, the sampler executes the script again. (This is what happens during this sample.)
  • If the script is not yet done, the sampler the sampler does not do anything.

Separate Thread

The Toolkit plug-in is executed separately from other non-Toolkit plug-ins. This was done so that the Toolkit plug-in would not block the results of other non-Toolkit plugins if in case the former had a long sample duration.

Although the plug-in has its own thread, multiple Toolkit plug-ins are executed sequentially by default. For example, if there are 3 Toolkit plug-ins (Toolkit A, Toolkit B, Toolkit C) in a Netprobe, these Toolkits are run sequentially. Hence, Toolkit A needs to finish before Toolkit B can be executed. There is setting found in the Advanced Tab of the Netprobe that allows Toolkit plug-ins to run simultaneously. The setting is maxToolkitProcesses. See below:
