Step – 1: Open Command prompt as Administrator

Step – 2: Use ‘msiexec’ tool for silent installation

  • To install CMON, use /package or /i
Syntax: msiexec /package <cmon-nd msi>
Example: msiexec /package G:\setup\cmon-nd.msi
  • To quiet the display option, use /quiet or /qn

ACCOUNT <domain\user name> To run CavMonAgent as service, use this parameter. In this parameter, user needs to provide windows server domain\username.
PASSWORD <Password> This parameter is required if user has given account name.

 

 Note Service Account details should be correct. Installer does not validate the details. If user has provided incorrect details, CavMonAgent service is NOT installed on windows server.

Syntax: msiexec.exe /package <cmon-nd msi> /qn ACCOUNT=<domain\username> PASSWORD=<password>

Example: msiexec.exe /i “C:\Users\compass-56\Downloads\cmon-nd.x64.4.1.6.58 .msi” /qn ACCOUNT=compass-56-PC\compass-56 PASSWORD=*****

For auto registration, user can provide command line parameters as following:

Parameter Name Parameter Value Description
INSTALLDIR <Absolute Directory Path> This is used to change installation directory path
CONTROLLER <Controller Host: PORT> Provide ND Controller Host and Port for auto registration
TIER <TIER Name> Used to provide Tier Name
SERVER <Windows Server Host/IP> From this parameter, user can register windows server host/IP (with NDE) for auto registration
INSTANCE <Instance> This parameter is for NDE. Here, user provides instance name of the application where ND Agent is plugged

Syntax : msiexec /package <cmon-nd msi> /qn INSTALLDIR=<Installation Directory Path> CONTROLLER=<Controller Host:Port> TIER:<Tier Name> SERVER=<Server IP/Host> INSTANCE=<Instance Name>

Example : msiexec /package G:\setup\cmon.msi INSTALLDIR=C:\home CONTROLLER=10.10.60.11:7895 TIER=WEBSTORE SERVER=10.10.30.65 INSTANCE=USER_APP_INSTANCE

Auto Registration of CMON-ND Agents

This is an optional feature, only in the case where NetDiagnostics Auto scaling capabilities need to be enabled.

The NetDiagnostics has a provision of auto scaling by which it can detect and start monitoring of any new instance or a server. However, if auto-scaling is disabled then NetDiagnostics is not be able to automatically detect and monitor the newly added server.

For NetDiagnostics to automatically monitor the newly added server, the auto registration of the agents is needed, where we provide the information of the tier, server, NetDiagnostics IP address as well as the NetDiagnostics port to the CMON agent. This is referred to as auto registration of agent.

To auto register new server, and to enable auto scaling, user needs to define certain configuration details in the following file:

C:\Program Files (x86)\opt\cavisson\monitors\sys\cmon.env

Configuration:

  • NDE Controller Address (Host and Port): User can configure NDE Controller as following:

CONTROLLER=<host:port>

  • Tier Name: At the time of enabling of auto-scale feature, user needs to define tier name. It is an optional field. Upon defining the tier name, the newly added server becomes the part of this tier. If the tier name is not defined, then the server becomes the part of default tier.

 Tier=<Tier Name>

  • Server: At the time of enabling of auto-scale feature, user needs to define server name. This server is registered with the specified tier. It is an optional field.
  • Instance: At the time of enabling of auto-scale feature, user needs to define instance name of the application where ndAgent is plugged in. This instance is registered with the specified server. It is an optional field.

For example:

#NDE Controller Host and Port - Mandatory
CONTROLLER=10.10.40.13:7890

#Tier and Server – Optional TIER=WebStore SERVER=<ip address or host name of server>

CMON Directory Structure

Following directories are created when the CavMonAgent package is installed in the following directory:

C:\Program Files (x86)\opt\cavisson\monitors

  • lib: Contains essential library files and jars required by CavMonAgent.
  • bin: Contains latest CavMon binaries and monitor programs/class files.
  • logs: Contains log files created by CavMonAgent and other monitor programs.
  • conf: Contains configuration information for running CavMon on windows based system.
  • thirdparty: Contains third party tools and programs.
  • etc: Contains version information.
  • sys: env file (this is created by user, for setting environments specific to user).
