Description: Provides XPath-based alarm filter expressions for selective alarm subscription in Ericsson network management systems.
Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.
What Is ERICSSON-ALARM-XPATH-MIB?
This MIB is an Ericsson-wide SNMP alarm interface, modeled on the 3GPP Alarm IRP and X.733, that adds XPath-based filter expressions so a management client can subscribe to a selective subset of alarm notifications rather than receiving the full alarm feed. It exposes summary counters of active alarms by severity (indeterminate through warning) plus per-notification objects carrying rich alarm detail such as additional text/info fields, resource identifiers, and record type. Its monitoring purpose is fault/status monitoring of Ericsson network elements: the severity summary counters give a quick health snapshot of a managed element, while the detailed notification objects (resource ID, additional info, record type) let an operator diagnose exactly what changed when an alarm is raised, cleared, or appended with more information. It is explicitly built on the 3GPP Alarm IRP specification and X.733 alarm model, and complements the related ERICSSON-ALARM-IRP-MIB and ERICSSON-ALARM-PC-MIB. It is deployed in Ericsson telecom network management systems, where ERICSSON-ALARM-XPATH-MIB SNMP monitoring lets operators filter which alarms are forwarded to a given monitoring station using XPath expressions.
IPNetwork Monitor allows you to monitor SNMP objects defined in ERICSSON-ALARM-XPATH-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.
Supported Devices
- Ericsson telecom network element
- Ericsson element manager/network management system
Monitoring Examples
An operator would monitor eriAlarmXSumCritical and eriAlarmXSumMajor for a quick severity-weighted health check of a network element, then, upon receiving an alarm notification, inspect eriAlarmXNObjResourceId and eriAlarmXNObjAdditionalText to identify the specific faulty resource and the human-readable fault description. eriAlarmXNObjAppendedAdditionalInfo would be checked to see whether new diagnostic information was appended to an already-active alarm, indicating an evolving fault condition rather than a new one.
What Can Be Monitored
- active alarm counts by severity
- alarm resource identifier
- alarm additional text/info
- alarm record type
- appended additional info on active alarms

How to Use in IPNetwork Monitor
Example using eriAlarmXSumIndeterminate OID:
Select an Ericsson telecom network element/element manager (XPath-filterable alarm subscription) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type eriAlarmXSumIndeterminate into the Find box to locate it in the OID tree, then select it and click OK. This object shows the number of currently active alarms with perceived severity 'indeterminate'. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Gauge32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.

| ericssonAlarmXpathMIB | 1.3.6.1.4.1.193.183.6 | This MIB Module is an Ericsson-wide SNMP interface for managing alarms. Main inputs to the MIB design are the 3GPP Alarm IRP and X.733. However, an important restriction is that the MIB only represents the resource view and not management activities like acknowledgment, etc. It describes generic notifications used to send alarm state changes and a table which represents the current active alarms in the system. The MIB supports both stateful alarms and stateless alerts. It is important to identify clearly what is to be considered the same alarm object instance. All unique alarm *types* are identified by 'AlarmType'. An AlarmType is a one-to-one mapping with X.733 EventType, ProbabableCause and SpecificProblem. A pair of integers are used to specify the alarm type. A unique alarm object *instance* is the combination of YangNodeInstance and AlarmType. In this way, there is no ambiguity about how alarm and alarm clear correlation should be performed: the same YANG resource instance and AlarmType shall be used. The same is true for changing existing alarm states. Severity, Additional Text and Additional Info can be changed on an existing alarm. For stateful alarms there are notifications to report a new alarm and a cleared alarm. Changing an alarm is done via the new alarm notification. The management system shall match the alarm by using alarm type and YangNodeInstance in the same way as for clear notifications. The MIB has different notifications for different severities in order to support SNMP managers which maps severities based on notification identifiers. For stateless alerts, there are generic notifications to send the alerts with different severities. NOTE - Updated Definition of Alerts in TEA (The Ericsson Architecture): Alerts are used by service management systems to evaluate service impact, and are only applicable to very specific state changes with potential service impact like restart and redundancy shifts. Alerts SHALL NOT be used for fault indication. Alerts should always have Perceived Severity Indeterminate, and should only be sent using eriAlarmXIndAlert notification. The other severity alert notifications should not be used, and are only present in this specification for backward compatibility reasons. A table lists all active alarms so that a manager can read an initial state and also perform an alarm resynchronization procedure. There is also a table of latest stateless alarms. Since the stateless alarms do not have a corresponding clear message, the table size is limited by the agent instrumentation. The MIB supports two approaches for detecting lost notifications: - sequence numbers are used in the alarm notifications, and are shown in the active alarm table. The last used sequence number can be read in a scalar variable - a time stamp indicates the last time alarm tables were updated. Heartbeat mechanisms are supported both in pull and push mode: - Pull: the classical SNMP polling where a manager polls a scalar variable, for example the last sequence number used - Push: the agent can be configured to send heartbeat notifications. These contains the last used sequence numbers. Document number: 11/196 03-CXC 172 7549. | ||

The actual format of the file is out of the scope of this MIB and can be found in the system documentation. A Uniform Resource Locator in accordance with RFC 4248. A string of length zero means that the agent does not have a URL to provide. |
| eriAlarmXActiveAlarmTable | 1.3.6.1.4.1.193.183.6.1.3.5 | not-accessible | This table list all active alarms in the system. The aspect is the resource view of the alarms, not the administrative states and processes performed by users. The number of entries, active alarms, can be read in eriAlarmXActiveNumber. Entries are created when a resource has a new alarm state. If the same resource has several active alarms, with different Alarm Types, this will be represented as separate rows. Rows disappear whenever the alarm is cleared in the resource. Rows can be changed when an alarm changes severity, additional text or additional info. Alarms where the clear state cannot be detected by the resource are not represented in this table. The contents of the active alarm table can also be fetched using file transfer. eriAlarmXActiveTableURL provides a URL to the file. | |
| eriAlarmXActiveAlarmEntry | 1.3.6.1.4.1.193.183.6.1.3.5.1 | not-accessible | One entry in the table holds one active alarm for a given resource. Entries are created by the system when a resource has a new alarm state. Entries are deleted by the system when a resource alarm state is cleared. Alarm severity, additional text and additional info can later be changed in a row. | |
| ERI eriAlarmXActiveIndex | 1.3.6.1.4.1.193.183.6.1.3.5.1.1 | EriAlarmIndex | not-accessible | A unique value, greater than zero, for each alarm. It is recommended that values are assigned contiguously starting from 1. The value for each alarm must remain constant at least from one re-initialization of the entity to the next re-initialization. Note that this index should not be used for alarm synchronization purposes since the 'logical' index for an alarm is - eriAlarmXActiveMajorType - eriAlarmXActiveMinorType - eriAlarmXActiveYangNodeInstance |

Different YANG Schema Nodes and instances can share alarm types, but if the same YANG resource instance reports the same alarm type, it is to be considered as the same alarm state. The alarm type is a simplification of the different X.733 and 3GPP alarm IRP alarm correlation mechanisms based on EventType, ProbableCause, SpecificProblem and NotificationId. For systems where eriAlarmXActiveMajorType is not needed for identification purposes, it is not used and MUST be zero-valued. |

A management system should also be prepared to receive a resource ID (OID) identifying the alarming resource if the system sending the notification can provide that information. In that case, eriAlarmXNObjResourceId will be set to 'true' and the resource ID will be sent in an eriAlarmXAppendInfo notification. | ||
| NTF eriAlarmXMinor | 1.3.6.1.4.1.193.183.6.2.0.3 | This notification is sent when a resource detects a new alarm state with severity minor. The notification is also used to change severity, additional text and/or additional info of an alarm. The eriAlarmXNObjRecordType varbind will indicate whether this is a new alarm instance or a change to an existing alarm instance. The combination of YangNodeInstance and MajorType/MinorType is always unique and can be used by management systems to correlate alarm, alarm change, and alarm clear. A corresponding row will be created in the Alarm Table, (eriAlarmXActiveAlarmTable). The sequence number will increase for every notification and can be used to detect lost notifications. A management system should be prepared for appending text to additional text, indicated by the eriAlarmXNObjMoreAdditionalText varbind, and sent with eriAlarmXAppendInfo.

| NTF eriAlarmXCleared | 1.3.6.1.4.1.193.183.6.2.0.7 | This notification is sent when a resource detects a cleared alarm state. The combination of YangNodeInstance and MajorType/MinorType is always unique and shall be used by management systems to correlate alarm and alarm clear. The corresponding row in the alarm table will be deleted, (eriAlarmXActiveAlarmTable). The sequence number will increase for every notification and can be used to detect lost notifications. Note that it should not be required to send an append trap for a cleared alarm. Those varbinds which flag that an append trap will follow are kept here for backward compatibility reasons. | ||
| NTF eriAlarmXAppendInfo | 1.3.6.1.4.1.193.183.6.2.0.8 | This notification is sent in order to append further info to an alarm notification. It might be additional text, additional info or a resource ID (OID) identifying the alarming resource using an OID. If additional text/info is sent, do not confuse this with an actual change of additional text/info which is reported using the eriAlarmX notification. A zero-length string value for eriAlarmXNObjAdditionalText means that no additional text is being sent in this notification. A zero-length string value for eriAlarmXNObjAppendedAdditionalInfo means that no additional info is being sent in this notification. A null OID (0.0) value for eriAlarmXActiveResourceId means that no resource ID is being sent in this notification. | ||
| NTF eriAlarmXIndAlert | 1.3.6.1.4.1.193.183.6.2.0.10 | This notification is sent when a resource detects a new alert with severity indeterminate.
