Diagnostic Tools

Oputils' diagnostic tools are used to check the availability, route and health of a system in a network using ICMP and SNMP. By drawing a graph with the available details, the tools show the status of a node. The tools also scan and check a range of IPs and come up with their status.
Tools included in this category are:

Ping – This tool is the graphic representation of the ICMP PING utility. It helps in discovery of the status of a network device, that is whether the device is alive or not. Before you ping a device you can configure the ping settings such as number of packets, time to live, size, and timeout.

Enhanced Ping – This tool compares the response time and packet loss of the given IP nodes. With options to view the data as a line graph or a bar graph, the enhanced ping shows the response time, the percentage loss, and an average value for each device pinged.

Ping Scan – Using this tool you can scan an entire range of IP Addresses to check their availability. The tool displays the IP Address, the response time, and the DNS name of the discovered device. This tool uses the basic PING function as a base to perform the scan.

SNMP Ping – This tool checks whether a node is SNMP-enabled or not. It helps the network engineers know the availability of a device and provides basic information such as DNS name, system name, location, system type, and system description. Following the SNMP discovery, if required, more details of the node can be retrieved using SNMP Tools such as SNMP walker, MIB Browser and SNMP Graph

SNMP Scan – Using this tool you can scan an entire range of IP Addresses using SNMP ping and check for their availability. The tool displays the IP address, response time, DNS name, system name, and system type.

Proxy Ping – The Proxy ping tool enables you to ping a target device using a Cisco router. The router acts as the proxy for the target device and responds to the ping request.

Trace Route – This tool records the route followed in the network between the sender’s computer and a specific destination computer. The user can configure the settings such as number of hops, and timeout.


Address Monitoring Tools

Address monitoring tools are used to manage IP Address, MAC address and DNS name of a network.
Tools included in this category are:

DNS Resolver – Network engineers can use this tool to quickly get the host name of any node whose IP Address is known and vice versa. It also shows details like the default netmask, network type, and the status for the forward and reverse lookups.

DNS Scan – Using this tool one can scan a range of IP addresses to see whether the forward and reverse lookup actions are working fine for the devices. It also shows the response time. In cases where an IP is not used in the network, the tool prompts that the system does not exist in the network.

MAC IP List - Provides a list of MAC Addresses and its corresponding IP Addresses and DNS names that are collected over a period.

MAC Address Resolver – The tool can fetch the MAC Address for any SNMP-enabled node, with the provided IP Address. This tool also discovers the physical address of a device and maps it with the corresponding IP address. In addition to showing the MAC address, the tool also shows the SNMP availability, IP address, DNS name, port number, community, system type, and system description.

MAC Address Scan – This tool scans a given range of IP Addresses and displays the MAC addresses for various devices available in the given range. The tool also displays the IP address, port number, community, MAC address, DNS name, system name, and system type.

Subnet List – This tool helps in retrieving the list of subnets accessible for a given SNMP node.

IP Address Manager – Using this tool, network engineers can identify whether an IP Address is currently available or not. The tool helps manage the IP addresses in a static DNS environment, using pre-defined user policy. The tool scans a subnet and provides the availability status of IP addresses in that subnet. One can check whether a particular IP is reserved or available. The tool accept multiple subnet inputs, which helps in scanning your entire network to get the status of the IP Addresses.

DHCP Scope Monitor – The tool fetches all the scopes that are defined in the DHCP Server and displays the total, used, and available IP Addresses in each scope. When the number of available IP addresses falls below a defined value, the display turns red to indicate the criticality.

Rogue Detection – When OpUtils detects a new MAC Address in the network either through periodic or manual scanning of subnets, the device gets added to this result as a rogue device. Initially, all the discovered MAC addresses will be shown here. The administrator has to verify the list and delete the valid devices. This is a one time configuration after scanning the entire network. Later on, if any new MAC address is found during the scanning process, it gets listed here.


Server Monitoring Tools

Server monitoring tools are used to monitor any desktop for CPU usage, hard disk usage, installed software, running processes, etc., through SNMP. This toolset also offers detailed information about the monitored device.

The tool discovers the devices plugged into each port of a specified switch. The tool is useful for system and network engineers to gain visibility into the IP, MAC, status and availability of ports. Since this is a real-time discovery you can also view the operational status and speed of each port. This tool maps switch ports to the devices connected to them. The tool accepts multiple switch inputs, which enable you to scan all the switches in your network simultaneously.

Performance Monitor – This is a utility to monitor and collect traffic statistics of any switch or router or any node. This is a real-time network monitoring tool that scans traffic for errors and discards, octet flow, and packet flow.

Network Monitor – The tool continuously monitors the response time of multiple devices and generates e-mail alerts based on the severity. These alerts are set up at three different levels and show the different status of the nodes.

Network Scan – The tool is a utility to scan a network for retrieving data such as machine types for each node in the network, the interface types, the OS present in the machine, the cable types available for the machine etc.

IP Network Browser – The tool is similar to the IP node browser but works with multiple nodes. The tool fetches comprehensive information on any node such as system details, interface details, TCP/IP network details, routes details, protocol statistics, and system information.

Wake-On-LAN – This tool remotely 'wakes-up' a machine (boots-up a machine) that is present in the network but not alive. For the tool to work, the PC should be configured to accept the Wake-On-LAN remote command. The tool enables you to 'Wake-up' multiple hosts simultaneously.

Port Scanner - This tool scans the given ports either in a range of IP Addresses or for a single IP to find the status of the scanned ports. The status of the ports can be either listening or not listening. You can associate the ports with the known services, which enables you to know the unknown/unwanted services running in the system.

System Details Update- This tool comes handy when the administrator has to update the system details, such as System Name, System Description, and System Location in a range of devices. The administrator can first scan a range of devices to view the existing details and then can modify as required and update them all at once.

SNMP Tools

It is common to have heterogeneous network environment hence the available tools in the OpUtils toolset might not be sufficient to monitor a wider range of devices. In such a scenario the SNMP toolset can be used to monitor such devices. The MIB database has a huge number of both private and standard vendor MIBs. Using tools such as SNMP walker, SNMP Graph and MIB browser one can monitor any SNMP device.
Tools included in this category are:

MIB Node Viewer – Many a times network engineers are aware of the MIB node (OID name) but not sure of the OID and its properties. In such situations this tool would be of great use. It accepts the node name or the OID as input and provides the complete information on the MIB node including MIB name, parent node name, OID, OID type, status, syntax, access, definition, and the next node.

MIB Module Viewer – This tool provides a snapshot of a given MIB. It provides some general information on the MIB, the defined attributes, total number of nodes, defined TCs, and the defined traps. It also provides the SMIv2-specific details.

SNMP Walker – A utility to retrieve specified number of MIB objects value using SNMP GET-NEXT operation. Using this tool you can provide any OID value and query a device for the next consecutive OIDs.

SNMP Graph – This SNMP tool gathers real-time data and draws a graph for any SNMP IP node. It also provides the MIB node information such as OID, syntax, description and MIB node properties.

Trap Receiver– This tool listens for real-time network traps and processes them.

MIB Browser –The MIB Browser tool is a utility that enables you to load and browse MIBs and perform SNMP operations. With this tool, you can perform all SNMP-related operations such as GET, GET-NEXT, GET-BULK, and SET. The above SNMP operations can be performed on the specified agent.

Community Checker – The Community Checker tools helps the administrators to identify the read and write SNMP communities of the SNMP-enabled devices in the network. This tools operates based on the standard and popular SNMP Community strings that are stored in the database. The administrator can add or edit the list to include all the community strings of the devices in their network.


Custom SNMP Dashboard (Professional Edition only)

While OpUtils provides a set of widely used tools to monitor the network, it also lets the administrators to create their own tools to suit their need. It allows creation of custom SNMP tools to monitor their SNMP devices. The Custom tool provides both the graphical and tabular views of the monitored MIB nodes. The tool thus created can be used to monitor any of the network deivces; no need to create separate tools for individual devices.

Custom SNMP Graph Tool – It enables monitoring any MIB nodes (of counter & integer data types) continuously and view the graphical representation of the monitored MIB node. All the related MIB nodes can be grouped to form a single multi-line graph for effective comparison. It also allows creation of multiple groups in a single tool.

Custom SNMP Tabular Tool – It enables real-time monitoring of any MIB node. The administrator can add all the required MIB nodes to this tool. This can then be used to view the current values of these nodes in any of the SNMP devices in the network
