Logging

All hardware events are logged to /var/log/messages and /var/log/dragen_mond.log. The following shows an example in /var/log/messages of a temperature alarm:

Jul 16 12:02:34 komodo dragen_mond[26956]: WARNING: FPGA software over temperature alarm has been triggered -- temp threshold: 85 (Chip status: 0x80000001)
Jul 16 12:02:34 komodo dragen_mond[26956]: Current FPGA temp: 86, Max temp: 88, Min temp: 48
Jul 16 12:02:34 komodo dragen_mond[26956]: All dragen processes will be stopped until alarm clears
Jul 16 12:02:34 komodo dragen_mond[26956]: Terminating dragen in process 1510 with SIGUSR2 signal

By default, temperature is logged to /var/log/dragen_mond.log every hour:

Aug 01 09:16:50 Setting FPGA hardware max temperature threshold to 100
Aug 01 09:16:50 Setting FPGA software max temperature threshold to 85
Aug 01 09:16:50 Setting FPGA software min temperature threshold to 75
Aug 01 09:16:50 FPGA temperatures will be logged every 3600 seconds
Aug 01 09:16:50 Current FPGA temperature is 52 (Max temp = 52, Min temp = 52)
Aug 01 10:16:50 Current FPGA temperature is 53 (Max temp = 56, Min temp = 49)
Aug 01 11:16:50 Current FPGA temperature is 54 (Max temp = 56, Min temp = 49)

If DRAGEN is executing when a thermal alarm is detected, the following is displayed in the terminal window of the DRAGEN process:

**********************************************************
**  Received external signal -- aborting dragen.        **
**  An issue has been detected with the dragen card.    **
**  Check /var/log/messages for details.                **
**                                                      **
**  It may take up to a minute to complete shutdown.    **
**********************************************************

If you see this message, stop running the DRAGEN software. Do the following to alleviate the overheating condition on the card:

• Be sure that there is ample air flow over the card. Consider moving the card to a slot where there is more air flow, adding another fan or increasing the fan speed.
• Give the card more space in the box. If there are available PCIe slots, move the card so that it has empty slots on either side.

Contact Illumina Technical Support if you are having trouble resolving the thermal alarm on your system.
