How To Simulate Network Devices Using SNMP SimulatorThis tutorial explains how you can simulate network devices for testing purposes with the free Verax SNMP Simulator. Verax SNMP agent simulator is a tool that can simulate multiple SNMPv1/v2c agents on a single host on standard 161 port through multi-netting. It allows IT personnel to build virtual, simulated networks of devices without purchasing any additional hardware, for instance for testing purposes. Individual simulated agent responses can be initially retrieved from existing devices and modified at runtime by user defined rules.   Req

How To Use Nagios Plugins In Verax NMSThis guide shows how to use Nagios plugins to monitor devices
in Verax NMS Express. Verax NMS is a cross-platform network and application monitoring software. Tools used:Sample Nagios plugin for CPU check in a Shell Script format

How To Set Up Multi-Level/Master-Slave Umbrella Network MonitoringThis guide provides an overview on how to set up umbrella monitoring to monitor applications and devices in distributed networks. Multiple instances of monitoring systems (in this example Verax NMS express) can be configured in a tree-like, master-slave, federated umbrella monitoring structure. This umbrella-like monitoring can be used to monitor geographically distributed
networks e.g. by telecommunications operators to manage regional, state
and national networks or managed service providers for managing their
clients’ infrast

Monitoring Linux And Unix Server Temperatures With OpsviewManaging power consumption in a Datacenter is a key factor in helping keep overall business energy costs down and ensuring servers are running at optimum performance. Overheating can lead to increased costs for cooling and also runs the risk of servers crashing. Opsview server monitoring software can be used to check and alert on server temperature and also the temperature of individual components within a server (Memory, CPU and Hard drives). Thresholds and alerts can be set for when critical temperatures are exceeded, helping to keep

Monitoring OpenStack Swift With OpsviewAs a starting point we’ll perform a ‘front door’ check as this should work no matter what Swift implementation you are using.Note that we’re using Authentication version 2.0 with Keystone rather than tempauth.The following assume you already have both Opsview Server and OpenStack Object Storage (Swift) configured and running.Pre-requisite set up tasksThe machine running the check needs to have a Swift client and an Opsview Agent. If you plan to monitor from a Swift proxy server you should only need the latter; if you plan to execute the checks from your O
