Check_Nexenta uses the Nexenta API to monitor system health and report performance data. It can also use SNMP for additional performance monitoring, and SNMP extends for custom performance and/or health monitoring.
- Report all warnings and criticals the Nexenta runners report (failed hardware, cluster issues, memory low, cpu high etc).
- Report performance data for CPU, Memory, Network, Volumes, Folders, Snapshots and Compression.
- Report warnings, criticals and performance data supplied by your own custom SNMP extend scripts.
- Warn on Volume and Folder available free space in % or MB/GB/TB.
- Warn on Snapshot used space in % or MB/GB/TB.
- Convert descriptions and warning levels of known errors.
