NetApp Monitoring

New and improved

• New check PerfSysNode (amends PerSys for clusters with DataONTAP 8.3+)
• New check LunAlignment

Fixed

• Sis: Handling of volumes where an error occurs while fetching the status values
• Better error handling if --storedir points to a non-writable directory

New and improved

• New check ServiceProcessor
• nfs counter in PerfVolume
• PerfDisk: additional counters (user_read, latency, total_transfers, ...)
• Systeminfo (model name, DataONTAP Version, ...) in Head

Fixed

• Usage: --check_only and --svm_in_name are compatible now
• check_netapp7_vfiler handles --check_network even if vfnet is empty
• check_netapp_quotas: Option --path filters by qtree-path now
• Distribution: takeover- and quota-check are now distributed as part of the ADVANCED Bundle
• Documentation: missing api aggr-scrub-list-info in list_apis.pl --mode=7m

Fixed

• Improved the error message in case of too less data in perf-stores.
• Fixed the error-message in case a filer does not return a counter-value.
• Removed example from Snapshots which shows how to search with Snapshots for volumes without Snapshots, as this did not work as expected. Using Snapshots to check for snapshot-less volumes will result in false negatives! Existing customers should check their configuration and replace these service-checks with the new SnapshotLessVolume check.

• Fixed a bug which stoped UsageTrend from working, if some instances have been created within the look-behind-period

New and improved

• New: check_netapp_takeover - checks if the take-over facility is enabled and takeovers are possible
• New check: SnapshotLessVolume - searches for volumes without a snapshot.
• New Check Job - checks for failed jobs.
• New switch --svm_in_name for the Usage-check prefixes the volumes name with the vserver. This avoids confusing duplicates in the output.

Important

Due to a change in the store-format existing store-files must be converted (or deleted) before upgrading! Please read the installation instructions.

Fixed

• --mammamia for 7m-getter did not write into storedir
• provide --check_only=without_lun_7m for 7m-filers
• check_netapp_anycli: Document switches --like_result and --unlike_result
• get_netapp_shelfenvironment: Do not stop if one node is down
• check_netapp7_vfiler.pl: Handle undefined vfiler-status
• SnapMirrorState: Avoid UNKNOWN caused by no longer existing snap-mirrors
• SnapMirrorState/Metric: Excluding all relations and setting --no_instances=OK is ok now

New and improved

• New check: LunSize
• Faster, leaner and more reliable store-format (existing store-files must be converted before upgrading! Please read the installation instructions.)
• New switch: --ignore_case (ignore case for --exclude and --include patterns)

New and improved

• New check: check_netapp_quotas.pl - monitors quotas on a cdot filer.
• StorageUtilization output units can be controlled by --factor=ki|Mi|Gi|...
• DiskPaths: Bugfix and additional switch --port_pattern_ok=AAAA | BBBB | ...
• ShelfEnvironment False positives regarding the shelf-status solved with switch --workaround_for_279931
• ShelfEnvironment: False positive for voltage-sensors in DataONTAP 9.1P1 (solved with temporary switch --DataONTAP_91P1)

New and improved

• New check: FCPAdapter checks fcp-adapters status (online, ...)
• Usage-check: --check_only=500GiB..1TiB (ranges to specify different thresholds depending on the volumes total size)
• New switch in PerfVolume: --math=average|total
• New metric in Sis: changelog-used-percent
• New switch --ignore=^temp__ in perfdata-getter - this is the default!
• New switch --node|--vserver-switch for VolumeAutoSize check
• New switch read_ops- and write_ops-counter for PerfDisk check.
• New switch --exclude=<counter> in perfdata-getter. Required to exclude the newly added _ops-counters on older filers.
• Specific cdot-getter for the ShelfEnvironment -Check; this new getter does not need the --node parameter any more.

Fixed

• ClusterPeerHealth: Returns "UNKNOWN - No matching instances found" instead of "no data" if no peer has been found

New and improved

• Performance and History-Checks: Improved usability by setting a mostly higher --tolerance and printing detailed instructions in case of a misconfigured getter.

  • The default for --tolerance is now always 50% of the --delta
  • The checks analyze the existing store-data and print any applicable solution to stdout.

Fixed

• Snapshots: --show_problems works now as documented
• Sis: handles sis-disabled volumes (skips them if --check_disabled is not set)
• PerfDisk: tolerance was missing

New and improved

• All getters can write to more than one storedir. This allows to check from more than one peer/poller. ATTENTION 1: You need either to start with an empty storedir or migrate existing stores. (See also section Upgrading to Version 3.6.x and 3.7.x in the docs.) ATTENTION 2: Storedirs do not get created automatically any more. Add --autocreate_storedir to the getters to get back to the old behavior.
• Direct checks with overall-logic (e.g. check_netapp7_fcpstats, check_netapp_scrub) can write their instance_results into more than one storedir.
• New Multi-Tenancy Checks: ReportSpace, ReportIOPS
• New Check Sis - check for dedup-problems (stale-fingerprints, run-time)
• New check check_netapp_scrub to alarm if last scrubs timestamp is over a certain age.
• Disk check has thresholds now - get a WARNING for 1 failed disk and a CRITICAL alarm for 2 or more.
• --max_records can be configured to reduce the time to collect data (volume, vol_snapshot, disk) from cdot-filers
• Snapshots can check the size of single snapshots now (--single).

New and improved

• A new format and logic for some store-files dramatically reduces the memory-footprint of checks using performance- and history-stores.
• New check_netapp_license.pl
• New switch --vserver for LunState
• New switch --prefix for PerfLif
• New switch --uninitialized_relation_is_ok for SnapMirrorMetrics (Useful if you setup a far away vserver peer and activated protection with snapmirror - synchronization can take a long time than.)
• New switch --exclude_dependency=vclone for the Snapshot check to filter on application-dependency
• Hint in output if instances have been excluded
• Snapshots-check: --node|--vserver is optional now

Fixed

• ShelfEnvironment fixed to check 7m MetroCluster

New and improved

• Length of output can be limited by setting max_length_multi_line in check_netapp_pro.pl

New and improved

• --average implemented into PerfDisk

New and improved

• New check ClusterPeerHealth
• New check MetroClusterVserver
• New option for the collector-checks: --no_store=OK|... (most useful together with the collectors option --no_instances=OK|...)
• DiskPaths: unassigned disks are skipped
• VolumeState: Node-filter --exclude_nodes/--include_nodes introduced

Fixed

• Usage-Check: Handling of volumes with no state-attribute
• shelf-environment-object in cm-getter needs a node-name (sometimes)
• snap-mirror getter for 7-mode: Handle empty config (no snap-mirrors)
• Respect the options --timeout and --hide_uuid

New and improved

• new DiskCount check (counts spare-disks per type or storage-pool)

• extended lun-object in the 7m/cm-getters (in preparation for a LunSize check)

Fixed

New and improved

• New option --display_factor for check_netapp7_snapvault.pl
• New option --skip_reason in Vserver check

New and improved

• New Option: --perfdata_uom_string to replace correct but not accepted units like '/s' with whatever you want. E.g. --perfdata_uom_string=s|persec|empty|°C|µs|us|...
• IfGrp lists ports which are down
• NetPort/NetPort7m: new switch --ignore_disabled
