Exception Log Test

This test reports general statistics pertaining to the log files in a host. 

Target of the test : Any host

Agent deploying the test : An internal agent

Outputs of the test : One set of results for the server being monitored.

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed.

Host

Host name/IP address of the server for which the test is to be configured

PortNo

The port on which the specified server listens for HTTP requests

LogFile

The name of the log file to be monitored.

LogDir

The full path to the specified log file.

EmptyFile

Enter either true or false. The entry true instructs the eG Enterprise suite to monitor even empty log files. The entry false instructs the eG Enterprise suite to ignore empty log files during monitoring. By default, this text box will hold the value false.

HighPattern

In order to track critical exceptions logged in the log file, you need to specify the pattern of such exceptions, here. For eg., if critical exception logs contain the string "Error", then your pattern specification could be *Error*. A leading '*' signifies any number of leading characters, while a trailing '*' signifies any number of trailing characters.

LowPattern

To monitor minor exceptions logged in the log file, the pattern of the minor exceptions has to be specified in this text box. For eg., if minor exception logs contain the string "Low", then the pattern specification could be *Low*. A leading '*' signifies any number of leading characters, while a trailing '*' signifies any number of trailing characters. 

MediumPattern

For monitoring the medium exceptions in the log file, the pattern of these exceptions needs to be defined in this text box. For eg., if medium exception logs contain the string "Warning", then the pattern specification could be *Warning*. A leading '*' signifies any number of leading characters, while a trailing '*' signifies any number of trailing characters.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

Total exceptions

Indicates the total number of exceptions logged in the log file

Number

A high value of this measure indicates the need to analyze the exceptions, ascertain their severity, and take corrective action if required.

High exceptions

Indicates the number of critical exceptions that have been logged in the log file

Number

System performance will suffer much on the occurrence of critical exceptions. Such exceptions will have to be fixed with immediate effect.

Medium exceptions

Indicates the number of not-very-critical exceptions logged in the log file

Number

Medium exceptions might not have an immediate impact on the system performance, but, in the long run, they could grow to be fatal. Such exceptions need not be looked into immediately, but will have to be fixed soon enough.

Low exceptions

Indicates the number of very minor exceptions in the log file

Number

Low exceptions are very negligible in nature and can be ignored.

Note:

If a log file to be monitored is not found or is empty, then the errcount will be 0.
