  Nagios-Plugins for NetApp Specifications  For the  present development-status  and additional links check out www.netapp-monitoring.info/en/matrix.html Caches BufferCache  checks several metrics of the systembuffer cache (=system memory) like Buffers beingread, Buffers being written, Empty (unused) buffers,Buffers with modified data, Buffers associated withCP IO, ... FlashCache  checks several metrics of the externalFlashCache (PAM II) like External cache hit rate, Av-erage latency of read I/Os, Number of wafl buffersserved off the external cache, ... NVRAM  checks data-rates and latency of theNVRAM. Hardware Hardware  checks the NVRAM, cooling-devices,temperature-sensors and power-supplies of the headand its shelves. Also checks all disks in the system, if they are in a broken, pre-failed or replacing state. Head  monitors the heads hardware objects (fans,NVRAM, power-supplies, health-state, temperature-sensors) Management StorageUtilization  Storage Utilization answers thequestion, “Am I effectively using the storage capac-ity available to my applications. Metro Cluster check_netapp_cluster  checks the status of the highavailability service (connected, taken over, takeoverfailed, ...). Cluster  checks the cluster-members regarding theirstate (connected, taken over, takeover failed, ...) andtime-master-status (master, slave). DiskPaths  checks if an interface-group has enoughactive links. SyncMirror  checks the mirror-status on Metro Clus-ter aggregates. Derzeit nur für den 7m sinnvoll, daMetroCluster auf cm-Filern nicht angeboten wird. Network IfGrp  checks the net ports link-status (up, down). NetPort  checks if the network-interfaces are enabledor not PerfIf   Checks and counts transfer-rates and errors pernetwork-interface (ifnet). Especially useful for moni-toring 10GbE-ports. Performance ConsistencyPoints  reads the performance-countercp_count twice and calculates the rate of CPs persecond. The argument –counter|-z defines the type of consistency-point (wafl-timer, back-to-back, ...). Theinformation gathered from this plugin corresponds tothe CPty-column of ’sysstat -x 1’. LunLatency  Checks the ’latency’ and ’operations persecond’ (ops) per LUN. Shows details for total, read,write and other. NetApp recommends monitoring la-tency as the primary performance indicator. PerfAggr  The area of application for this plugin isto monitor performance-relevant aspects of capacitymanagement within an aggregate -in other words, thepercentage of free blocks available for writes withinan aggregate (ignoring all reservations, guarantees, orthe like - just the free space available to the write al-locator). This allows to proactively order additionalstorage for an aggregate before write performance isimpacted. PerfCpu  checks one or all processors in a NetApp sys-May 9, 2014, Version check_netapp, check_netapp_prowww.netapp-monitoring.info  tem for their utilization. PerfDisk  checks all disks in a NetApp system for theirutilization (Percentage of time there was at least oneoutstanding request to the disk). Optional the checkcan be limited to the disks of a single aggregate. PerfSys  checks various performance coun-ters of the NetApp-system (mostly opera-tions/second and transfer-rates). Counters sup-ported: net_data_sent, dafs_ops, total_ops,disk_data_written, net_data_recv, cifs_ops,streaming_pkts, http_ops, nfs_ops, fcp_ops,disk_data_read, iscsi_ops PerfVolume  Checks the ’latency’ and ’operations persecond’ (ops) per volume. Shows details for total,read, write and other. NetApp recommends monitor-ing latency as the primary performance indicator. Snap SnapMirror  checks and logs: lag-time, pair-state,pair-transfer-status, last-transfer-duration, transfer-errors. SnapVault  monitors a SnapVault-relationship (lag-time, state, last-transfer-duration, transfer-errors) Storage OvercommitAggr  Returns a list of aggregates to-gether with their overcommitment in percent. Over-commitment is the relation between the aggrgates sizeand the total of all its (thin provisoned) volumes sizes. Quotas  sends an alarm, if one of the defined quo-tas are exceeded. One service-check can monitor thewhole filer, since we use the internal definitions of thequota-system as thresholds. Snapshots  checks, if the snap-reserve is still sufficient.Thresholds are set in percent; performance-data canbe either in percent or absolute (Byte). Additional cri-teria are the age or name of the snapshot. This canbe used for monitoring snapshot-backups and whetherthey are up to date or not. Also can be used to findsnapshots related to a specific application like SNMVand check all volumes for left-over snapshots. Usage  checks the used space in volumes and aggre-gates. Thresholds can be set in GB or percent. Status AggregateState  checks the aggregates-state.Alarms if they are not online (configurable). check_netapp_spare  monitors the status of thespare-low condition (alarms if there is no suitable sparedisk available). iSCSI  monitors one or all iSCSI-adapters (online, of-fline, local, partner, error). Raidstatus  alarms, if one of the RAIDs is degraded. ShelfBay  checks, the shelf- and disk-port status. Canalarm BYP-status disks. Status  alarms, according to the global-status. Uptime  checks the seconds since last reboot. vFiler  monitors the status of a vFiler (if the vfiler isrunning and if the network resources are configured) VolumeState  checks the volume-states. Alarms if they are not online (configurable).May 9, 2014, Version check_netapp, check_netapp_prowww.netapp-monitoring.info
