Info

During the Iguana Server migration, you might need to manually resubmit queued message from the old Iguana into the new Iguana. There are two ways to achieve it.

Iguana Log Export

  1. Navigate to Iguana Logs

  2. Configure the following Search Criteria:

    1. Channel

    2. Type=Message

    3. Hide Deleted

    4. Time Range (If know the queued message time range)

  3. Choose on Export

  4. Choose A CSV file

  5. Click on Export button to generate CSV

  6. Open CSV in Excel and Delete None “Message“ type logs (such as “Ignored Data Msg“)

  7. Back Iguana Logs with the same Step 2 Search Criteria

  8. Click on “Last Processed Message” link

  9. Scroll up/down to find the “Last Processed Message“ message that has “PROCESSED“ tag and click on it

  11. Use refid to find the last processed message in CSV file

  12. Find refid in CSV MessageId column and delete all the earlier processed messages include the “Last Processed Message“

  13. The remaining messages in CSV are queued messages

Iguana Translator

  1. Copy the Lua code below into your translator

  2. Update the CHANNEL_NAME, QUEUED_COUNT, and LOG_COUNT

  3. Update Iguana Log API endpoint if you query logs from another Iguana

  4. Run the Lua code

  5. Retrieve Queued Messages from line 56

      if tonumber(id1List[2]) >= tonumber(id2List[2]) then

   end
