Getting Started - Monitoring

Once a device is discovered, a set of default monitors are automatically associated to your devices based on its type. These monitors collect essential data from the device and help in calculating the performance of your devices and also contribute to the creation of performance reports.

How to add monitors in OpManager?

Apart from the default monitors, you can also add various other performance monitors to your devices based on your environment needs.

Before adding monitors to your respective devices, kindly ensure the following:

Proper credentials must be associated.
Devices must be associated with the respective device templates.
The monitor you are trying to add must be compatible with the selected device.

1. Adding monitors individually:

To add monitors to an individual device, go to Inventory -> Device -> Monitors -> Add Monitor.

2. Adding monitors in bulk:

Likewise, to add monitors in bulk, go to Settings -> Configuration -> Device Template and click on the necessary device template to add device specific monitors and apply it to the whole bunch of devices.
You can also add monitors by navigating to Settings -> Monitoring -> Performance Monitors -> Associate adds bulk monitors to a bunch of devices.

3. Adding custom monitors:

For WMI and SNMP-enabled devices, OpManager allows you to create custom monitors suited to your needs.

These custom monitors can be added in various ways as mentioned below :

Open the "Device Snapshot" page and click on the "monitors" tab. Now, under the actions dropdown, click on "Add WMI/ SNMP"
Navigate to Settings -> Monitoring -> Performance Monitors and then click on the "Add monitor" button at the top right. Now click on SNMP/ WMI according to your needs.
Navigate to Settings -> Configuration -> Device Template and then click on a device template. Now, click on the "Add" option found to the right of "Associated monitors". Now click on SNMP/ WMI according to your needs.

Apart from performance metrics, users can also add various other monitors to keep track of other critical aspects of the devices. Here is a detailed overview according to the monitoring types.

Types of Monitoring	Subtypes	Description
Availability Monitoring	Network Availability	Helps you check the Availability/Uptime of your network devices using either ICMP (default), TCP or SNMP protocol. You can also track other metrics like Interface Availability, Service Availability, etc.
Network Monitoring	Wireless Monitoring	Helps you monitor the wireless devices in your network.
	IPSLA Monitoring	Helps monitor WAN links and quality of VoIP between Cisco devices.
Server Monitoring	Application monitors	Helps you monitor the applications in your systems such as Exchange servers, Active directory and MS SQL.
	Files and Folders Monitors	Helps you monitor the files and folders in your server.
	Process monitors	Helps you monitor the background processes running in your environment.
	URL monitors	Helps you monitor the status of external URLs as well as the URLs running in your system.
	EventLog monitors	Helps you monitor your device's eventlogs.
	Script monitors	Helps you monitor the scripts running in your environment.
Virtual Monitoring	VMWare	Provides in-depth, agentless monitoring of VMWare virtualized servers.
	HyperV	Monitor the details of your HyperV server and gain complete visibility over the performance of your hosts and VMs.
	Citrix	Monitor hosts, VMs and storage repositories of your Citrix XenServer and provides the required visibility into their performance .
HCI	Nutanix	Discover your Nutanix cluster and monitor all hosts and VMs under that cluster.
Storage Monitoring		Helps you monitor and manage the storage devices such as RAIDs and tape libraries. You can also manage Fiber Channel switches in your network. Learn more.
Agent-based monitoring		Helps you monitor the devices in your network with the help of a light piece of software called the agent that is installed on the end devices. The agent gathers the data from the devices and then sends it to the main server for further analysis. Learn more.
UCS monitoring		Helps you monitor the status and availability of UCS devices. Learn more.
Health monitoring	Hardware health monitoring	Helps you monitor the hardware health and key metrics such as temperature, voltage, power, etc .
	IPMI monitoring	IPMI is a widely accepted standard supported by a lot of hardware vendors. OpManager uses IPMI to monitor the health of hardware devices in real-time using SNMP/ API.

Once the monitors are all set, it is important to identify baseline values(Thresholds) that ensure the optimum functioning of the devices. Breach of these thresholds will trigger an alarm according to the criticality of the situation.

How to configure thresholds in OpManager?

In order to ensure the proper functioning of devices, thresholds are set. To prevent overclocks, and ensure the optimum functioning of the devices, OpManager cross-references the monitor data with the defined thresholds. In case a discrepancy is found, OpManager will alert the concerned person at the earliest according to the criticality of the situation. This ensures maintaining the optimum performance of devices. Users can configure thresholds to devices by the following:

Automated threshold configuration: Adaptive Thresholds is an automated threshold configuration feature that enables network admins to perform threshold configuration easily by advanced predictive algorithms and percentage-based calculations.
Manual threshold customization: Thresholds can be customized for all the monitors that are associated with your devices. These thresholds serve as a metric to generate alerts when violated. Learn more.
