There are three basic approaches to monitoring devices on your network:
- The device sends details into Opsview Monitor when events happen or on a regular schedule. For more information, see SNMP Traps and Passive Checks.
- Opsview Monitor runs checks to test network connectivity to the host and the services it provides. For more information, see Active Checks and SNMP Polling.
- Opsview Monitor talks to an agent installed on the device to see what is happening ‘on the inside’.
This document discusses how to achieve the last item in the list.
The ITRS Infrastructure Agent is the recommended agent to install on monitored servers, and supports both Windows and Linux.
The Infrastructure Agent enables communication between systems by running a daemon that Opsview Monitor Collectors can use to interrogate the status of the system. It provides some default plugins (for checking on RAM, CPU, and DISK, amongst others) that Host Templates within Opsview Monitor can make use of straight away, but can be extended with additional plugins.
For installation details on any distribution see Infrastructure Agent Installation.
WarningWe do not recommend manually installing or upgrading the Infrastructure Agent on servers which run Opsview Monitor itself, as these already have packages managed by Opsview Deploy.
The Opsview Agent is still supported, but we recommend that new customers and existing customers deploying new monitoring use the ITRS Infrastructure Agent instead. Please follow the instructions above for the latest information on the ITRS Infrastructure Agent.
To view information about the Opsview Agent, you can refer to the Opsview documentation version 6.8.4 or earlier.
