Configuration field

Description

Tachyon User Name

This is the user configured in ServiceNow and is responsible to fetch or execute instructions to or from Tachyon. Enter the Tachyon username and domain here, to add a user in Tachyon refer Tachyon Platform 8.1 - Users document.

Tachyon User Password

This is the password for Tachyon user to fetch and execute instructions.

Tachyon keep answers minutes

This value is used when ServiceNow sends an instruction to Tachyon and displays how long a Tachyon response is active after the instruction is executed, with a default value of 120with a valid range between 10 and 10080. The same feature is available in 1E Core as well. If an admin has not provided a value, Tachyon uses the value saved in the 1E Core app.

Tachyon gather data minutes

This value shows the timeframe in minutes for how long Tachyon should gather the instruction response data. It has a default value of 60 with a valid range between 10 and 10080. The same feature is available in 1E Core as well. In case admin has not provided any value, then Tachyon server by default considers the value saved in 1E Core app.

Page size

When devices are fetched (synced) from Tachyon into ServiceNow, these are fetched into batches. This feature sets the batch size for same. The default value is set to 1000.

Response batch size

The responses of instruction that are fetched from Tachyon into ServiceNow are fetched into batches. This feature sets the batch size for these responses. The default value is set to 100.

Response batch size for Tachyon Information Service

The feature Tachyon Information Service (TIS) trigger Tachyon instructions on all available end-user devices at once. These responses of instructions that are fetched from Tachyon into ServiceNow are fetched into batches. This feature sets the batch size for these responses. The default value is set to 1000.

Response API wait seconds for Tachyon Information Service

When an instruction is triggered from ServiceNow to Tachyon as a part of 'Tachyon Information Service', there is a continuous calling from ServiceNow to Tachyon for fetching the responses. In case there is no response available on Tachyon for this instruction, then the next response call is triggered after these many seconds. The default value is set to 10.

There is a continuous counter on Tachyon from ServiceNow for getting responses. If responses are not empty, then the counter is set to 0 whereas if responses are empty (i.e. there is no response) then the counter is increased by 1. In case there is no response for more than three times from Tachyon, then we increase this wait time as shown in the following formula:

Wait time = (Counter value / 3) * 5 * (Response API wait seconds for Tachyon Information Service)

For example: If wait counter is 7 and wait time is set to 10 seconds by an admin on the configuration page, then wait time = (7 / 3) * 5 * 10 = 2 * 50 = 100 seconds.

The value 5 here is called a poll multiplier. To change this value update the value in the x_1e_tachyon_cmdb.pollMultiplier property.

The listed devices allow an admin user to configure the types of devices that are to be synced from Tachyon to ServiceNow. In the current version, only the Endpoints (Desktop/Laptop) are available for configuration.

Note

If Endpoints (Desktop/Laptop) is disabled, no devices are synced with Tachyon.
