Description
Monitors Solaris ZFS Storage Pool health status and usage capacity in percentage. [NET-SNMP-EXTEND-MIB::nsExtendOutLine-1.3.6.1.4.1.8072.1.3.2.4.1.2]
Prerequisites
Need to add following Zpool command to snmpd.conf in end device:
extend zpool_name /bin/bash -c “zpool list -H -o name”
extend zpool_capacity /bin/bash -c “zpool list -H -o capacity”
extend zpool_health /bin/bash -c “zpool list -H -o health”
Then do SNMPWALK query on OID: 1.3.6.1.4.1.8072.1.3.2.4.1.2 on end device,
it must give above Zpool commands output in SNMP output.
Means it should give Zpool names, Zpool health status and Zpool capacity in percentage.
Sample SNMP query output:
NET-SNMP-EXTEND-MIB::nsExtendOutLine.“zpool_name”.1 = STRING: zpool_test1
NET-SNMP-EXTEND-MIB::nsExtendOutLine.“zpool_name”.2 = STRING: zpool_test2
NET-SNMP-EXTEND-MIB::nsExtendOutLine.“zpool_health”.1 = STRING: ONLINE
NET-SNMP-EXTEND-MIB::nsExtendOutLine.“zpool_health”.2 = STRING: ONLINE
NET-SNMP-EXTEND-MIB::nsExtendOutLine.“zpool_capacity”.1 = STRING: 44%
NET-SNMP-EXTEND-MIB::nsExtendOutLine.“zpool_capacity”.2 = STRING: 51%
Metric Parameters
| Parameter | Description |
|---|---|
| Frequency | Warning Threshold | If the metric value satisfies the condition defined along with Warning Threshold value, then a notification is sent to the user. |
| Critical Threshold | If the metric value satisfies the condition defined along with Critical Threshold value, then a notification is sent to the user. |
| Alert | The alert value can be set to either Yes or No. If it is Yes, then an alert message is sent to the user. |

| SNMP OID | NULL |
| Expression | NULL |
| Description | It represents the Solaris ZFS Storage pool health status. A pool's health status is described by one of following states: DEGRADED: A pool with one or more failed devices, but the data is still available due to a redundant configuration. ONLINE: A pool that has all devices operating normally. SUSPENDED: A pool that is waiting for device connectivity to be restored. A suspended pool remains in the wait state until the device issue is resolved. UNAVAIL: A pool with corrupted metadata, or one or more unavailable devices and insufficient replicas to continue functioning. UNKNOWN: A pool is not imported and its actual status has not been verified. This health status is used by zpool label command. CLEARED: A pool has at least one device with ZFS metadata cleared by using zpool label -C command. A cleared pool cannot be imported.
