Prerequisites

The communication between the NMS and U2000 is normal.

Context

The NMS can use either of the following methods to obtain alarm files:

l The NMS uses SFTP to obtain alarm files from the specified path on the U2000 server. l The U2000 uploads alarm files to the NMS.

NOTE

The following uses the first method as an example.

U2000

Introduction to Alarm Export Tool and File

About This Chapter

This chapter describes the alarm export tool, formats of alarm export files, alarm export operations, and troubleshooting.

3.1 Alarm Export Tool

The alarm export tool exports alarm logs and event logs from the alarm database to the files in the specified directory on the server.

3.2 Alarm Export File

This section describes the path, categories and quantities, naming conventions, formats, and deletion policy of alarm export files.

3.3 Alarm Export Operations

Alarm export operations consist of modifying configuration files of the alarm export tool, setting automatic alarm export, and stopping automatic alarm export.

U2000

(19)

3.1 Alarm Export Tool

The alarm export tool exports alarm logs and event logs from the alarm database to the files in the specified directory on the server.

Functions of the Alarm Export Tool

The exported alarms still exist in the database.

Configuration File of the Alarm Export Tool

The configuration file of the alarm export tool is /opt/oss/server/etc/alarm/locale/en_US/ fmexportsvc_field.xml, this configuration file defines the name, value, and sequence of alarm information fields in the exported file.

Automatic Alarm Export

After the export function is started, the alarm export tool automatically exports the new alarms after the previous alarms are exported from the alarm database to an alarm export file at a specified time each day. If you have modified Property > Extended Parameters > Filter Condition in the export tool, the alarm export tool exports all data in the alarm database based on the new filter condition. Later, the alarm export tool exports only the incremental data.

Automatically Uploading Exported Files

The U2000 can automatically upload exported files through FTP. Choose Software > FTP Auto Upload Management > Target Server Settings (traditional style); alternatively, double-click System Management in Application Center and choose Settings > FTP Auto Upload Management > Target Server Settings (application style) on the client to set the relevant parameters. After you set the parameters, the U2000 automatically uploads the exported files to the specified FTP server every five minutes by default. The NMS can therefore obtain the generated files. For details about how to configure this function, see the

U2000 Online Help.

3.2 Alarm Export File

This section describes the path, categories and quantities, naming conventions, formats, and deletion policy of alarm export files.

Path of Alarm Export Files

All alarm export files are saved in the /opt/oss/server/var/fileint/fm/ directory by default. If this directory is not available when you export alarm files, the export tool automatically creates this directory.

Categories and Quantities of Alarm Export Files

During alarm export, each type of alarms (current alarm logs and event logs) are exported to a file. Each file records a maximum of 5,000 alarms. If the number of a specific alarm type exceeds 5,000, the export tool saves additional alarms to a new export file.

U2000

(20)

Naming Conventions of Alarm Export Files

l Naming Conventions

Alarm export files are named in the following format: File Prefix-Date and Time

[DST]-Alarm category-auto-Sequence number-Extension, where

The file prefix field takes effect only if you have set the File Prefix parameter while creating alarm export tasks on the U2000 client. The parameter value is case sensitive and composed of 0 to 30 digits or letters. For details, see Help.

The date and time field records the time when alarms are exported. DST indicates that alarms are exported during daylight saving time. [] indicates that the sign is not used in non-DST period.

The alarm category field records the category of exported alarms. The value can be alarm-log or event-log, which represent alarm logs and event logs, respectively. A maximum of 5,000 alarms of the same category can be exported to a file. Additional alarms of the same category are exported to another file. Files are numbered sequentially from 1. If one file is enough to store all exported alarms, the file number is 1.

The extension field indicates the format of a file, which can be set to .xml, .csv, .txt, or .html. If you select a compression mode for export, the extension field is .zip or .gzip according to the compression mode you select.

l Examples

20091006120300-alarm-log-auto-1.xml indicates an alarm log file in .xml format and exported at 12:03 on October 6, 2009.

20091006120300-event-log-auto-1.zip indicates an event log file compressed in .zip format and exported at 12:03 on October 6, 2009.

Formats of Alarm Export Files

The configuration file <U2000 server installation directory>/etc/alarm/locale/en_US/ fmexportsvc_field.xml defines the alarm field information and the sequence and name of each field contained in the alarm export files. You can modify this configuration file as required. For details, see 3.3.1 Modifying the Configuration File of the Alarm Export Tool.

l CSV, TXT, and HTML

In a CSV, TXT, or HTML file, the first row lists the fields recording alarm information, such as the NE name, alarm name, and alarm severity. From the second row, each row corresponds to an alarm.

l XML

In an XML file, each <Record name="AlarmRecord"></Record> corresponds to an alarm.

Following is an example XML file:

<?xml version="1.0" encoding="UTF-8"?> <ExportFileInfo name="AlarmRecords"> <Record name="AlarmRecord">

<column name="Log Serial Number">2</column> <column name="Object Identity Name">OSS</column> <column name="Object Identity">OS=1</column> <column name="ProductName">NMS</column> <column name="NEType">OSS</column>

NOTE

l Some messages are displayed in multiple lines due to the large size of contents. In the actual file, these messages are displayed in one line.

l When interconnecting the system with the NMS through the northbound alarm interface, you are advised to use the alarm ID instead of alarm name to identify alarms. This improves the efficiency of identifying alarms.

l When parsing the location and additional information about alarms, you are advised to parse the information based on alarm names instead of forcibly specifying the location and number of related parameters. When the NMS parses parameter names, ensure that the parameter names are case insensitive.

l Considering that NE alarm severity may be adjusted based on NE versions, you are advised not to forcibly specify the severity of a certain alarm.

l Format description of the alarm generation time: For example, the alarm generation time provided in the alarm export file is 2013/4/13 06:37:43 GMT+08:00, where

l 2013/4/13 06:37:43 refers to the local time, calculated using the following formula: Local time = GMT + Time zone.

l GMT+08:00 refers to the time zone.
