Updated Microphone Log Format
The order of columns in microphone log files has been changed, and a CSV-style header row has been added to make the file easier to read.
The new column order and headers are as follows:
- DATE TIME
- SN
- DURATION
- HEATER
- SENSOR
- PRIMARY_CAL
- BACKUP_CAL
- TARGET_CAL
Please note that this format differs from previous versions of SMART software. Users with automated scripts may need to update their integrations to accommodate this change.
See Microphone Log Files in the SMART User Guide for a full description of the new format.
Fixed: Alerts Log File Filled with Processing Messages
The alerts log file, /var/www/html/storage/logs/system name-alerts-log.txt was filling up with messages each time the process was executed. These messages were removed and the process will now only log messages with information when an alert is activated.
Fixed: undefined variable $log Message in Cron Log
The cron log file was showing this error message. The root cause has been fixed.
Fixed: SMART Mics Appeared as "Missing" During Startup
When the SMART is starting up, or a microphone is connecting, the system can take a few seconds to display the microphone status (usually “idle”). Now, while a mic state is unknown, the status shown on the devices page will be “Connecting” until the system has time to determine the real status. This should take less than 30 seconds.
Fixed: OPC Alarm Did Not Trigger when Removing One of Two Microphones
If two mics are connected to the SMART, and one is unplugged, the
SystemMicMissingEventType OPC alarm did not trigger. This has
been fixed.
Fixed: GUANO Metadata System Software Version
The GUANO metadata incorrectly reported the SMART Software version as 1.3.0. This has been fixed.
Added Pre-Trigger and Post-Trigger Durations to Recording Metadata
SMART did not include the Pre-Trigger and Post-Trigger duration values in their GUANO metadata. These values are now added.
Fixed: Daily Emails not Delivering to Users with Gmail Addresses
When configured to send the daily maintenance emails to multiple users, any users in the list with gmail addresses would not receive the email. This was due to a formatting issue in the email file which has been fixed.
