Informix Logical Logs Test

The logical logs are one of the most important resources of the database server. Your database server will be blocked if they become full because they could not be backed up. You might also lose transactions in the case of a failure, if your logical logs have not been backed up. Thus, observing the behavior of the logical logs is essential. This test collects and reports measures related to the logical logs.

Target of the test : An Informix Dynamic server

Agent deploying the test : An internal agent

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

Configurable parameters for the test
Parameters	Description
Test Period	This indicates how often should the test be executed.
Host	The IP address of the Informix Dynamic server.
Port	The port number at which the specified host listens to.
Instance	The Informix server instance being monitored.
User	A valid Informix user name.
Password	The password corresponding to the above user.
Confirm Password	Confirm the Password by retyping it here.
DBLocale	Specify the language/locale in which your database is installed. This will allow you to return the query in the language supported by your database. By default this attribute is set to “none”, which means that by default, queries are returned in the English locale.
ClientLocale	Specify the language/locale in which the eG agent is running. Normally, when you use an internal agent to monitor Informix, the ClientLocale and DBLocale will be same. However, the ClientLocale may differ when you are monitoring the Informix tests using a remote agent (agentless monitoring). By default, the ClientLocale is set to “none”, indicating that the eG agent runs in the English locale, by default.
