zabbix-ecc

Zabbix template & script to monitor ECC errors on Linux.

It uses kernel's EDAC infrastructure to read the info directly from SysFS.

Single Python script that emits all information needed for discovery & data gathering in a single JSON. All items are defined as Dependent and extract relevant data using JSONPath queries.

Features

• Low level discovery of:
  • DIMMs/Ranks
• Items:
  • Correctable Errors
  • Uncorrectable Errors
  • Location
  • Size
• Triggers:
  • Correctable Errors
  • Uncorrectable Errors
• Zabbix agent passive checks. Can be converted to active if needed.

Macros

• {$EDAC_CE_THRESH} - Number of correctable errors to trigger on (>0 by default)
• {$EDAC_UE_THRESH} - Number of uncorrectable errors to trigger on (>0 by default)

Requirements

• Tested on Zabbix 5.2, but should work on 4.2+
• Python3

Installation

• Place edac.conf in /etc/zabbix/zabbix_agentd.d
• Place edac.py in /etc/zabbix/scripts You can put it into any other place, but then you'll have to adjust edac.conf
• Restart zabbix-agentd
• Import template_edac.xml
• You're good to go
