Network Analysis & Troubleshooting

Contact Us for Expert Help

How do you manage the madness without ending up in a straitjacket?

You can’t troubleshoot what you can’t see … or find … or don’t know.

Avaria troubleshoots business computer networks by pro-actively implementing granular-level end-to-end monitoring with pre-set thresholds. Best-practice network and server management is in our DNA.

That’s why we are infatuated with device & service metrics, alerts; and we provide round-the-clock proactive maintenance. When things exceed threshold values, or simply stop working, our experienced team of engineers focus on immediate remediation and post-failure analysis. And after successful remediation, recommend and implement changes to mitigate similar situation in the future.

Overview

At the most basic level (we won’t bore you with too many details), a business technology network may have:

• Network switches, firewalls and routers, wireless access points, and printers: all of which have CPUs, memory, and operating systems
• All these devices pass all sorts of network traffic; have all sorts of resources utilization
• There are storage devices, which in turn, have their own embedded devices such as network cards, and embedded operating systems, and data traffic (think iSCSI)
• There are physical hosts (e.g. vmware), and then there are guest VMs living on these physical hosts.
• Hosts have their own OS, and physical resources (RAID controllers, network cards, CPUs, memory, system boards etc.).
• Guest VMs present their own set of variables such as virtual CPU (vCPU), virtual RAM, guest OS, and hundreds of services (think RDP, SSH, http, ftp, MS Exchange, SQL, etc) PER VM.
• Let’s not forget power devices such as UPSs and PDUs, which generate their own data.

Once you multiply all of these, you end up with thousands, if not hundreds of thousands, of things that can go wrong. Knowing, in real-time, and with real-time networking knowledge to go straight to the issue, IS HOW AVARIA MANAGES UPTIME FOR YOUR BUSINESS NETWORK.

Avaria’s network management engineers:

• Discover, Inventory and Document ALL of your IT infrastructure resources (end-to-end, single site or multi-sites).
• Set up metric thresholds, implement monitoring, and setup alerts of ALL resources.
• Assign right engineering manpower to tackle the ‘red alarms’.
• Make sure red alarms are tackled within minutes and not hours. Escalation thresholds are managed by account managers and service desk managers.
• And maintain a robust CHANGE MANAGEMENT system. 80%+ problems happen AFTER a change; change management is the only way to go!

Network Topology Discovery & Mapping

Network Topology Discovery & Mapping
	Discover and diagram network topology. Discovery methods including SNMP, ICMP, WMI, CDP, VMware®, Microsoft® Hyper-V® & more. Leveraging a unique multi-level network discovery technique, our mapping tools discover your LAN or WAN and we produces a comprehensive, easy-to-view network diagram that integrate OSI Layer 2 and Layer 3 topology data.

Multi-Level Network Discovery
	Our powerful network discovery software performs multi-level network discovery to produce an integrated OSI Layer 2 and Layer 3 network map that includes detailed device information.

Network Mapping for Regulatory Compliance
	Our powerful network mapping software, Network Topology Mapper, allows you to directly address PCI compliance and other regulations that require maintenance of an up-to-date network diagram.
