Apache Monitoring Agent for OMI Server

Apache-Provider

The Apache-Provider project implements a CIMOM provider, based on OMI, to return logging and statistical information for Apache. Apache is an open-source HTTP server created by the Apache Software Foundation. The Apache-Provider runs on Linux systems as far back as RedHat 5.0, SuSE 10.1, and Debian 5.0.

The Apache-Provider project implements two independent components:

  • An Apache module to collect statistical information from the HTTPD server and make it available to the OMI provider, and
  • An OMI provider to report Apache information via OMI

The Apache-Provider provides the following classes:


The following output shows the results of enumeration of classes:

Enumeration of Apache_HTTPDServer

    ServiceName=_Unknown
    OperatingStatus=OK
}

Note that properties InstalledModules and InstalledModulesFormatted are virtually identical. InstalledModules is an array of strings, which is a data type natively supported by OMI. Some software may have difficulty consuming such a data structure, however. As a result, the same data is available in InstalledModulesFormatted, which is formatted as a comma-separated string.

Due to this formatting, module names with embedded commas may be difficult to properly differentiate.
