Defining Text File Reading and Monitoring Jobs

You can define a Text File Reading and Monitoring (TEXT_MON) job to search a text file on a Windows, UNIX, or i5/OS computer for a text string. For example, you can monitor a log file for an error message after a script executes.

Note: To run these jobs, your system requires CA WA Agent for UNIX, Linux, Windows, or i5/OS.

Required Statements

To define a Text File Reading and Monitoring job, you must specify the following statements:

Optional Statements

You can specify the following optional statements for a Text File Reading and Monitoring job:

Example: Search for a Text String on a Windows System

This example searches for a text string in a text file on a Windows computer. The path to the text file is enclosed in single quotation marks because the path contains a space. The job searches between lines 1 and 20. The job completes successfully if the string is found.

AGENT SYSAGENT
TEXTFILE 'c:\Program Files\CA\component.txt'
TEXTSTRING 'CreateService failed' EXIST
SEARCHRANGE LINE FROM(1) TO(20)

Example: Monitor an i5/OS Text File for a String in the First 20 Lines of the File

This example searches for a text string in the DATA member of a QSYS file object on an i5/OS computer. The job searches the content between lines 1 and 20. The job completes successfully if the string is found.

AGENT I5AGENT
TEXTFILE /QSYS.LIB/LIBRARY.LIB/RESULTS.FILE/DATA.MBR
TEXTSTRING 'Create file failed' EXIST
SEARCHRANGE LINE FROM(1) TO(20)

Example: Monitor a File for a String using a Regular Expression

In this example, the text string contains regular expression pattern matching syntax. The search range is also a regular expression as indicated by the operand REGEX in the SEARCHRANGE statement.

AGENT SYSAGENT
TEXTFILE '/home/cybesp/file.txt'
TEXTSTRING '^\w{4,10}\.' EXIST
SEARCHRANGE REGEX FROM(\A\W\sE)

The regular expression can be interpreted as follows:

^ or \A—match only at the beginning of string (line)
\Z or $—match only at the end of string
\w—a word character [a-zA-Z0-9]
\W—a non-word character
\s—a whitespace character
{4,10}—match at least 4 times but not more than 10 times

To illustrate the last item {4, 10}, consider the following syntax:

TEXTSTRING 'b1{1,3}c'

Evaluating this expression yields the following conditions:

The line contains the text b1.
Numeric 1 should exist at least once, but not more than three times.
The specified text string must be followed by the letter c.
