Clearvision Status Plug-in - Technical Reference

Introduction

The ClearVision status plug-in reads the status webpage as produced by a GL ClearVision server, making the values produced available within the Geneos monitoring framework. Once available these values can then be used for rules and alerts as normal.

Each instance of the plug-in will produce two views for the configured server. Multiple servers can be monitored by running multiple plug-in instances - one plug-in per server required.

Views

Server View

The server view displays general server state information as reported by the ClearVision status page. An example view is shown below.

Plug-in Configuration

The ClearVision status plug-in is only available when running a Windows Netprobe. The plug-in reads information from the status webpage generated by the ClearVision server, and so must be able to access this file to operate correctly.

The plug-in may optionally read the location of the status file from the Windows registry. In this case the Netprobe must run on the same host as the ClearVision server, and have read access to the registry to read these values.

Configuration for this plug-in is placed in the clearvision-status configuration section.

serverName

Specifies the name of the server to monitor. The plug-in will then use this name to access the following registry key where (by default) the status file location is stored in the "path" value.

HKEY_CURRENT_USER\Software\ClearVision\Server\<name>\Options\Web page\Server status

Mandatory: No (however one of serverName, fileLocation or registry must be specified).

fileLocation

Specifies the location of the ClearVision status file as a path - this can be a UNC path if required. When using this parameter the Netprobe does not have to be on the same host as the ClearVision server, provided the file is still accessible.

Mandatory: No (however one of serverName, fileLocation or registry must be specified).

registry

Specifies a registry key containing the location of the ClearVision status file. When using this setting the Netprobe must be running on the host that holds the registry entry (typically the ClearVision server host).

Mandatory: No (however one of serverName, fileLocation or registry must be specified).

registry > key

Specifies the location of the registry key to read a value from. This key must be a sub-path from HKEY_CURRENT_USER. E.g. specifying path "Software\Windows" will open the key "HKEY_CURRENT_USER\Software\Windows".

Mandatory: Yes

registry > value

The value to read inside the specified registry > key.

Mandatory: Yes
