When disk usage exceeds certain thresholds, administrators are notified through the appliance’s monitoring configuration within the Edge Portal.
Below are the two most common disk email alert scenarios, along with explanations and recommended actions.
Case 1: Disk Alert for ‘/mnt/data’
Description:
A warning alert is triggered when the /mnt/data mount — which stores most of TrendMiner’s critical application data such as indexes, packages, logs, and databases — exceeds 80% usage.
For email alert example, you might receive an message indicating that only 19.98% (19,127 MiB) of space remains available as shown below.
Recommended Action:
Follow Disk space extention guide to extend storage. Expanding storage ensures TrendMiner can continue to write data and perform indexing operations without interruption.
Case 2: Disk Alert for Root Directory ‘/’
Description:
A warning alert is also raised when the root directory (/), which holds the server’s system-critical files — including boot files, binaries, configuration files, and temporary data — reaches 90% usage.
For email alert example, you might receive an message showing only 9.93% (507 MiB) of space remaining as shown below.
Recommended Action:
Contact TrendMiner Support to investigate the cause of the root directory filling up.
