Description

Definition File for monitoring text-formatted logging File.

Copy the template (fluentd_@@trapname@@_tail.conf.template) and change file name of Copy destination to fluentd_log-monitoring-name_tail.conf for use. File name must be unique within integrated agent host. For details on the location of fluentd_log-monitoring-name_tail.conf, see Appendix A.4(3) Integrated agent host (Windows) and Appendix A.4(4) Integrated agent host (Linux) in the JP1/Integrated Management 3 - Manager Overview and System Design Guide. log-monitoring-name must be between 1 and 30 characters long. Allowed characters are single-byte alphanumeric characters, "-" (hyphen), and "_" (underscore).

Create a monitor-definition file for each wrapped-around log file group that you want to monitor (or for each log file that does not wrap-around). JP1/IM - Agent creates a IM managed node for SID of target of monitoring according to the value specified in IM-management-node-label-name of the IM managed node in the monitoring definition file. If another monitoring definition file has the same IM-management-node-label-name, only one IM management node is created.

The text-based log file monitoring feature reads this definition file and analyzes the log that the application has written to the text-based log file. You can setup if you specify a condition for the analyzed information and the condition is met, the information to be converted to JP1 events or output to Fluentd logging file. For details about JP1 event to be issued, see 3.2.3(2) JP1 event issued that monitoring a textual log File.

Lines beginning with "#" are treated as Comment and do not affect the programming behavior.

The default definition in [Forward Settings] section is set to transform log data to JP1 event and transfer to JP1/IM - Manager when SEVERITY is worse than Warning.

When transforming log data to JP1 event and transferring it to JP1/IM - Manager, set SEVERITY so that its severity is equal or worse than Warning.

worker-id (optional)

Description	Changeability	What You Setup in Your JP1/IM - Agent	JP1/IM - Agent Defaults Value
Specifies the number of workers that Fluentd will start. Serves as an argument to the <worker N> directive. Valid values are integers from 1 to 128.	Can be changed	It must be specified so as not to duplicate the worker ID specified in the existing text log file monitoring definition file or the Windows event log monitoring definition file.	1

[Metric Settings] section

Setup Value of label of sample that you want to send to JP1/IM - Manager's Trend data Management Database.

log-monitoring-name (mandatory)

Specifies log-monitoring-name specified in the file name of copy destination as a string of 1 to 30 characters. Allowed characters are single-byte alphanumeric characters, "-" (hyphen), and "_" (underscore). The default value is "@@trapname@@".

Because you need to setup several locations in the file, use OS command/editor function to replace the "@@trapname@@" location with log-monitoring-name you want to specify.

If the specification is omitted, error occurs when Fluentd is started.

Note that log-monitoring-name must be setup as follows:

• All log-monitoring-name in the same file are the same.

• log-monitoring-name is unique for the monitoring text-formatted log file definition file and the Windows event log monitoring definition file

host-name (optional)

Specify the host name to be monitored using characters 1 to 255 other than control characters. The default value is setup by integrated agent installers.

If the specification is omitted, IM management node is not created.

You can also dynamically setup the canonical host name of the system by doing the following:

    instance ${Socket.gethostname}

IM-management-node-label-name (optional)

Specifies the character string that integrated operation viewer displays on IM management node label. This is not a control character. When URL is encoded, the character string must be between 1 and 234 bytes (the upper limit for multibyte characters is 26). The default value is "Application".

If the specified information is invalid or omitted, IM management node is not going to be created.

You can specify the same IM management node label name in different monitoring definition files. Then, only one IM management node is created, and JP1 events in both of monitor-defined files are Add to one IM management node.

category-ID (optional)

Specifies the category ID of IM management node corresponding to SID to be monitored for logging as a character 1 to 255 other than control characters. If the specification is omitted, "otherApplications" is assumed.

[Input Settings] section

[Attributes Settings] section

Serup Attributes of JP1 events to be issued and Attribute value.

log-monitoring-name (mandatory)

Same as description of [Metric Settings] section.

event-ID (optional)

Specifies Value to Setup for B. ID property of JP1 event. For details about Value that can be specified, see JP1/Base Operation Manual. The default Value is "00007601" (Event ID used for monitoring text-formatted log file definition file).

If this option is omitted, JP1 events are not issued.

Instead of specifying "ID event-ID", you can setup event ID according to the value of message property by specifying:

    ID "${
         if record['message'].match(/regex-1/)
           'event-ID1'
         elsif record['message'].match(/regex-2/)
           'event-ID2'
         elsif record['message'].match(/regex-3/)
           'event-ID3'
...
         else
           'event-ID4'
         end}"

The conditional branch of Ruby determines value of message property and turns setup event ID. In the above cases, if regex-1 is matched, event ID is set to the value as specified in event-ID-1. If it doesn't match, it will setup event-ID-2 if it matches regex-2. If none of the matches are compared by the number specified in elsif, else statement setup value specified in event-ID-4. to event ID. You can specify a maximum of 100 if and elsif statements.

host-name (optional)

Same as description of [Metric Settings] section.

If the specification is omitted, the attribute value of JP1_SOURCEHOST is not setup and JP1 event is not add to the correct IM management node.

You can also dynamically setup the canonical host name of the system by doing the following:

    JP1_SOURCEHOST ${Socket.gethostname}

severity (optional)

Specifies the value to setup for E.SEVERITY property of JP1 event. For details about the value that can be specified, see the JP1/Base User's Guide. The default value is "Notice".

If this option is omitted, JP1 events are not issued.

Instead of specifying "SEVERITY severity", you can setup the severity according to the value of message property by specifying:

    SEVERITY "${
         if record['message'].match(/regex-1/)
           'Critical'
         elsif record['message'].match(/regex-2/)
           'Error'
         elsif record['message'].match(/regex-3/)
           'Warning'
...
         else
           'Notice'
         end}"

The conditional branch of Ruby determines value of message property and turns setup severity. In the above cases, "Critical" is setup to severity if the regex-1 is matched. If it doesn't match, it will setup "Error" if it matches against regex-2. Setup "Notice" in else construct to severity if elsif matches none of the specified numbers. You can specify up to 100 statements of if and elsif.

IM-management-node-label-name (optional)

Same as description of [Metric Settings] section.

If this option is omitted, JP1 events are not issued.

any-attribute-name any-value (optional)

Specify this operand if you want to Add a JP1 event-attribute. For details about Attribute name that can be specified, see JP1/Base Operation Manual.

For Value, you can specify the captured name in the [Input Settings] section with the regular expressions to parse the logs.

For example, to capture with the name "NUMBER" and Setup to the property EXIT_CODE, you would specify:

EXIT_CODE ${record['NUMBER']}

You can Add more than one extended attribute, but no JP1 event is issued if the sum of the sizes of Value that Setup the extended attribute of JP1 event exceeds the limit.

For details about the upper limit of extended attributes, see 4.4.4(5)__transformEvent method.

[Inclusion Settings] section

Specifies the conditions of the log to be monitored in a regular expression. If not specified, all logs are monitored. If an unmonitored log is output, the log is not converted to a JP1 event and is not output to Fluentd log.

In the default Setup, "#" is specified at the beginning of the line and is handled as Comment, so when specifying it, "#" is going to be deleted.

log-monitoring-name (mandatory)

Same as description of [Metric Settings] section.

attribute-name-of-JP1-event (optional)

Specifies the attribute name of JP1 event. For example, "MESSAGE". If the specification is omitted, error occurs when Fluentd is started.

regular-expression-of-logs-to-monitor (optional)

Specifies a regular expression for the value of the attribute specified by the attribute name of JP1 event. If the value to be match is included, monitoring is performed.

If the specification is omitted, error occurs when Fluentd is started.

You can also specify a logical AND or OR condition for multiple regular expression patterns. For details about how to specify the log data, see 3.15.3(7) Log data extractor (grep plug-in) in the JP1/Integrated Management 3 - Manager Overview and System Design Guide.

[Exclusion Settings] section

Specifies the conditions for logs that are not monitored, in regular expressions. If not specified, all logs are monitored. In the default Setup, "#" is specified at the beginning of the line and is handled as Comment, so when specifying it, "#" is going to be deleted.

log-monitoring-name (mandatory)

Same as description of [Metric Settings] section.

attribute-name-of-JP1-event (optional)

Specifies the attribute name of JP1 event. For example, "MESSAGE".

If the specification is omitted, error occurs when Fluentd is started.

regular-expression-of-logs-to-monitor (optional)

Specifies a regular expression for the value of the attribute specified by attribute-name-of-JP1-event. If value to be match is included, monitoring is not performed.

If the specification is omitted, error occurs when Fluentd is started.

You can also specify a logical AND or OR condition for multiple regular expression patterns. For details about how to specify the log data, see 3.15.3(7) Log data extractor (grep plug-in) in the JP1/Integrated Management 3 - Manager Overview and System Design Guide.

[Forward Settings] section

Setup the regular expression of the log data to be converted into a JP1 event.

log-monitoring-name (mandatory)

Same as description of [Metric Settings] section.

attribute-name-of-JP1-event (optional)

Specifies the attribute name of JP1 event. The default value is "SEVERITY".

If the specification is omitted, error occurs when Fluentd is started.

regular-expression-for-logs-that-emit-JP1-events (optional)

Specifies the condition for regular expressions that issue JP1 events for the value of the attribute specified by attribute-name-of-JP1-event.

The default value is "Warning|Error|Critical|Alert|Emergency" and matches if the value of SEVERITY is greater than or equal to Warning.

If Value of the attribute contains a Value that Match the condition, the monitored log content is converted to JP1 events and Add to JP1/Base in Integrated manager host. The content of the monitored log is also output to Fluentd log. If you do not Match the condition, JP1 event is not issued and only logged in Fluentd.

If the specification is omitted, Error occurs when Fluentd is started.

In the [Attributes Settings] section, "Notice" is specified as the default SEVERITY. Therefore, the log monitoring result is not output as a JP1 event. It is output only in Fluentd log.

If you want to publish a log with a SEVERITY of "Notice" as a JP1 event, change the definition as shown in the underlined part:

    pattern /Notice|Warning|Error|Critical|Alert|Emergency/
