Memfault logging with timestamps

[rene_pvh]

Hello support,

For our project we have an integration with Memfault for metrics, coredumps and log files.

We are currently developing in NRF 2.7.0 on a nrf9160 chip.

Transmitting log files works with the function memfault_log_trigger_collection() and memfault_zephyr_port_post_data().

I have the following logging configuration:

CONFIG_MEMFAULT=y

CONFIG_MEMFAULT_LOGGING_ENABLE=y

CONFIG_MEMFAULT_LOGGING_RAM_SIZE=4096

CONFIG_MEMFAULT_COMPACT_LOG=y

The received log file in memfault has the following layout:

E <err> bme680: Bad BME680 chip id: 0x0I<inf> BH1749: BH1749 initialized

E <err> ADXL372: failed to read id (0x0:0x0)I<inf> LSM6DSO: Initialize device lsm6dso@2

I <inf> LSM6DSO: chip id 0x6c

The output on my serial monitor is with a timestamp before each log line. Is there an option to transmit these timestamps also to memfault?
I have already tried with CONFIG_MEMFAULT_COMPACT_LOG disabled and also with CONFIG_MEMFAULT_PLATFORM_LOG_FALLBACK_TO_PRINTK enabled but both actions wont change anything.

I have also tried to overwrite the timing function with the config CONFIG_MEMFAULT_SYSTEM_TIME_SOURCE_CUSTOM

I am using the normal zephyr LOG_INF and other functions in my application.

Is there an alternative way to add the timestamps to the memfault log?

Thank you in advance!

Best regards,

Hello,

timestamp logging in memfault is currently not possible, but there is a feature request for it so I assume it is being worked on.
