DOC0000740: Setting a Telegram Group for a Swarming Session

To set up a Telegram group for a major incident, do the following:

On the Administrator's computer

1. Download and set up Infrastructure Agent.

2. Create a Telegram client. 

   To create a Telegram client, complete the steps below:

   1. Get registered in Telegram, using any client name.

   2. Follow the https://my.telegram.org link for authorization.

   3. Complete the form on the https://my.telegram.org/apps website to receive the URLs and parameters of api_id and api_hash needed for the users' authorization.

   It is possible to link only one api_id to the telephone number.

3. Open the folder downloaded in Step 2 and run the "createGroup" script manually.
   The four scripts in the folder are:
   
   • createGroup – to create a group,
   • cancelGroup – to restrict commenting upon the completing of the incident and changing its state to Completed,
   • deleteGroup – to delete a Telegram group,
   • clientInformation – to store api_id and api_hash.
4. Complete the user's authorization that the system will require. As a result, a "router.session" file is created.

On the SimpleOne instance

1. Create a new server in the MID Server (MID_server) table.
2. Create three scripts in the MID Scripts (MID_script) table. To do so:
   1. Click New and in the new Script Form 
   2. Add a name of the script (for example, createTelegram)

   3. Add the path to the script on your computer in the Script field.

      createGroup

      Path:
      Parameters:

3. Go to the System Properties (sys_property) table, set the value true for the itsm.telegram.swarming property.
4. Repeat the previous step to add the scripts to close and delete a group.
5. Go to System Properties (sys_property) table and add the IDs of the three created scripts to the corresponding properties as their values.
6. Go to a major incident form. Now there appears a Start Swarming button. Click it for the first time, and a record with a corresponding name appears in the MID Queue (sys_mid_queue) table. 

1. A closeGroup record in the MID Queue (sys_mid_queue) table appears when the incident state is changed to Done. Commenting in the group is unavailable, but the participants can read the messages.
