Translates raw NetApp syslog messages into human-readable explanations, structured formats, or forwarding-ready outputs for platforms like Splunk.
NetApp storage systems generate syslog messages packed with cryptic event codes, severity levels, and internal references. This translator takes those raw syslog lines and converts them into clear, actionable explanations — or reformats them into structured outputs suitable for SIEM platforms, monitoring dashboards, or documentation.
Storage administrators often need to quickly understand what a syslog entry means without digging through NetApp documentation. Whether you're troubleshooting a failed disk, investigating a network connectivity alert, or forwarding logs to Splunk for analysis, having a plain-language breakdown of each message saves significant time. This tool handles the interpretation so you can focus on resolution.
Paste in raw syslog output from your NetApp ONTAP or Data ONTAP system and get back a decoded explanation, a Splunk-compatible key-value format, a structured JSON object for ingestion pipelines, or a concise incident summary for your team. It works with EMS events, SNMP-related messages, audit logs, and standard syslog severity levels.
Jan 15 03:22:11 netapp-cluster1 [kern.warning] disk.failmsg: Disk 0a.01.3 (S/N: ABC1234567) has failed.
A physical disk has failed on your NetApp cluster. Disk 0a.01.3 (serial number ABC1234567) on node netapp-cluster1 is no longer operational. This is a warning-level event indicating hardware failure in shelf 01, bay 3 on adapter 0a. If this disk is part of a RAID group, the aggregate is now running in degraded mode. A spare disk should be assigned automatically if one is available. Verify RAID status with "storage disk show -broken" and contact NetApp support to arrange a replacement disk under your support contract.

Mar 22 09:17:45 cluster-mgmt [kern.notice] mgwd.clus.nic.linkDown: Cluster network interface e0c on node node01 is down.

Apr 10 22:41:08 fas8200-01 [kern.crit] callhome.battery.low: System battery on controller fas8200-01 is critically low. AutoSupport message sent.
INCIDENT: Critical NVRAM Battery Low on fas8200-01 Severity: Critical — Immediate action required Affected Component: NVRAM battery, controller fas8200-01 Description: The NVRAM battery charge on controller fas8200-01 has dropped to a critically low level. The NVRAM battery preserves cached write data during power loss. If the battery fails completely, the controller may shut down to prevent data loss, causing a failover event. Next Steps: 1) Verify partner node is healthy and ready for takeover. 2) Schedule an urgent battery replacement. 3) Confirm AutoSupport was received by NetApp support. 4) Monitor with 'system battery show'.
May 03 11:30:22 node01 [kern.info] wafl.vol.autoSize.done: Volume vol_data on SVM svm_nfs has been automatically grown from 500GB to 600GB.
An NFS data volume automatically expanded. Volume vol_data on storage virtual machine svm_nfs grew from 500 GB to 600 GB through the autosize feature. This is an informational event — the volume was approaching its space threshold and ONTAP triggered automatic growth as configured. No action is required unless the volume is approaching its maximum autosize limit. You can review autosize settings with "vol show -vserver svm_nfs -volume vol_data -fields autosize-grow-threshold-percent,autosize-maximum-size".
It handles standard NetApp ONTAP syslog output including EMS (Event Management System) events, WAFL messages, disk and RAID alerts, SAN/NAS notifications, cluster interconnect events, callhome/AutoSupport triggers, and general system health messages. Both ONTAP 9 cluster-mode and legacy 7-Mode formats are supported.
In ONTAP 9, you can configure syslog forwarding with 'event notification destination create' or view recent events with 'event log show'. For syslog server forwarding, configure a destination under 'event notification create' pointing to your syslog server IP. In 7-Mode, use 'options syslog.server' to set the remote syslog target. You can also pull logs from /mroot/etc/log/mlog/ on the node shell.
The Splunk key-value format output is designed to be compatible with Splunk's automatic field extraction using KV_MODE=auto. You can paste the output into a log file monitored by a Splunk forwarder, or use it as a reference to build field extraction rules (props.conf/transforms.conf) for your raw NetApp syslog input.
The translator will still parse the structural elements of the message — timestamp, severity, node name, and message body — and provide the best interpretation it can based on the content. For uncommon or custom EMS events, the explanation may be more general, but the structured output formats will still extract and organize all available fields.
Yes. You can paste multiple syslog lines at once. Each line will be interpreted individually. If a single event spans multiple lines (common with stack traces or detailed callhome messages), paste the entire block and the translator will treat it as one event.
