How can we help?

General Information


A Host is a monitored system, in a physical environment such as a router, switch, firewall, storage device or server. For a virtualized environment, Hosts would also include each Virtual Machine with a unique IP address. For example, if you had one server running ESXi, which hosted 5 Virtual Machines, your total Host count would be 6 (1 for the ESXi server and 5 Virtual Machines). Conversely, if you had a switch with 48 interfaces, this would still represent one host. Opsview Monitor licensing is based upon the number of monitored Hosts. For a more detailed explanation into what a Host is, visit our Knowledge Center.
Service Checks are the 'things' monitored on the hosts. These could be almost anything, but examples include CPU, Memory and Disk Space. With Opsview Monitor, you can monitor as many Service Checks per host as you require, and the amount of Service Checks per host does not affect the cost of licensing.

The Opsview Monitor agent runs directly on the monitored host and allows Opsview Monitor to run plugins on the host. It then passes the results back to the monitoring system. The advantage of the agent is that it has local access to many of the machine's resources and does not rely on exposed services or APIs. The Opsview Monitor agent is available for Windows and Linux systems. You can find a list of supported operating systems and download them.

Agentless checks run Opsview Monitor plugins on the Opsview Monitor system, which then query the host without the need for additional software to be installed on said host. These are normally designed for services that are available remotely like applications with an API, or technologies like Windows WMI or SNMP.

SNMP is most common on Network devices but is also available on other systems. Opsview Monitor is able to query SNMP devices with SNMP polls and accept SNMP traps, where the device then sends the SNMP data directly to Opsview Monitor.

Opsview comes with some pre-built SNMP Service Checks but can quickly and easily monitor many SNMP enabled devices by accepting a MIB file. This allows you to run an SNMP Walk to find all of the available data. Information on setting up SNMP traps can be found here.

Hashtags are a great way to group components and/or features with Opsview Monitor. Each hashtag has its own view, which lets you see exactly what is going on in your custom Hashtag groupings. Any outage on any Hashtag host or service check will show that Hashtag as down. Many Opsview Monitor reports are based upon the information provided by Hashtags and they’re also incredibly useful for alerting. There is more information about that in the Reporting section within the Knowledge Center.

Opsview's Business Service Monitoring (BSM) allows you to create groupings of hosts and services like Hashtags but take it further. BSM allows you to alert on the health of a service, rather than an individual Service Check. For example, if you have a database and a replica set up, the database service can still be considered OK if one of them fails, but CRITICAL if they both fail.

BSM allows you to easily see the overall status of your high-level services, giving a much broader view of your overall service status rather than just viewing individual host status. You can see the status of Business Services in the dedicated BSM view or using dashlets within the dashboards. Just like Hashtags, Business Service Monitoring can be used in the reporting module to generate reports. Since BSM understands the system dependencies and relationships, real SLA reports can be generated, no need for manual calculations.

Think of an Opspack as a plugin or integration. Opspacks are written by Opsview engineers and also Community members enabling you to monitor any and all technologies; whether existing or emerging. We support over 3500 plugins, Service Checks and much more. This makes it easy to monitor everything from Docker and VMware to Apache, Amazon Web Services, Hyper-V and many more technologies. Take a look at our whole list on the Opspack Marketplace.
