IntroductionIntroductionSynology DiskStation Manager (DSM) allows users to monitor the status of their Synologyservers through Network Management Systems (NMS) via Simple Network ManagementProtocol (SNMP). However, Synology DSM does not provide SNMP trap capability.This document introduces Management Information Base (MIB) files of Synology servers. Itfocuses on which MIB files are supported by DSM, while also describes how Object Identifiers(OIDs) in Synology MIBs are used with your preferred NMS software. Users are encouraged tohave experience and knowledge of NMS and SNMP before consulting this document.01

Supported MIB filesSupported MIB filesDSM and SRM supports numerous MIB files that can help users monitor different informationon their Synology NAS/IP SAN (hereinafter referred to as Synology servers). Table 1 shows theMIBs supported by DSM and SRM.These MIB files can be separated into two types: general SNMP MIB and Synology MIB. GeneralSNMP MIB files are equipped on NMS clients natively.Synology MIB files can provide specific data about a Synology server system, disks, RAID, andconnected UPS devices. Please see the “Synology MIB Files” section below for more SynologyMIB information.You can download the Synology MIB file here.Note: For all tables in this document, unless otherwise noted, DSM denotes that this OIDis compatible with DSM 6.2.4 and above, and DSM UC denotes that this OID is compatiblewith DSM UC 3.0.Table 2 General MIB Files Supported by IBSNMP-USER-BASED-SM-MIBExplanationFor defining event triggers and actions for networkmanagement purposesFor scheduling SNMP set operations periodically or atspecific points in timeFor use in managing host systemsFor describing network interface sub-layersFor the management of CIDR multipath IP RoutesFor IP and ICMP management objectsFor entities implementing the ICMPv6For entities implementing the IPv6 protocolFor entities implementing TCP over IPv6For entities implementing UDP over IPv6For monitoring structures for the Net-SNMP agentFor scripted extensions for the Net-SNMP agentDefines Net-SNMP extensions to the standard VACM viewtableFor logging SNMP NotificationsTo help support coexistence between SNMPv1, SNMPv2c,and SNMPv3The SNMP Management Architecture MIBFor Message Processing and DispatchingFor the SNMP User-based Security Model03

Synology MIB filesSynology MIB filesThe following Synology MIB files are provided in DSM. These MIB files are the child-nodes ofOID (Object Identifier) Table 3-1 shows the exact OID of each MIB. Pleasenote that the MIB files are mutually dependent. Before your NMS can monitor any of the itemsin these MIB files, please make sure that all of them have been imported together and useSNMPv2c to obtain the complete Synology OID information.Table 3-1 OID of Synology rgetFile arget-MIB05LastupdatedversionDSM 6.0.2DSM 7.0DSM 7.0DSM 6.0.1DSM 6.0.1DSM 6.2.1DSM 6.1.7DSM 6.0.1DSM 6.2.2DSM 6.1.7DSM 6.2.1DSM 6.2.2DSM 7.0DSM 6.2.2SRM 1.2.5DSM 7.0

Synology Disk MIB contains several types of information regarding hard drives, includingID, type and so on, as listed in Table 3-3. This MIB is a table in SNMP. As such, it can increaseor decrease in size when disks are inserted or removed. For example, if a disk is inserted, anadditional row containing relevant information will emerge. The OID DiskIndex (.1) is reservedfor an index of table rows and cannot be accessed.

Monitor Specific OIDsMonitor Specific OIDsIn any NMS, particular MIB files are needed in order to capture data through SNMP. Usersneed to import all MIB files to ensure that the NMS can resolve specific OIDs. Once imported,data can be captured by setting up the NMS. Although the means of operating different kindsof NMS may vary, the process of OID monitoring is similar. The overall procedure is as follows.1. Import MIB file into NMS.2. Set up the NMS to monitor specific OIDs.The followi
