Visual ping tool series#

Two options are currently available: name which represents name under which the series will appear in graph and depth which defines number of values that series will store. Series options should be stored in data node of host's node. Number of sent pings used for recent history.Р”Р„dditional options are available for data series that represent source for showing hosts' statistics in graphs. Time between unsuccessful try and new try to obtain host's IP address using DNS. Number of unsuccessful pings before pinger declares host as dead.

Time that pinger waits after it receives reply from previous ping and before it sends another ping. If IP address is not specified, pinger uses this host name to query DNS server and obtain IP address of the host. If IP address is not specified, pinger uses this name to query DNS server and obtain IP address of the host. Host pinger can be configured with following options: Name of XML element in the configuration file that stores option How long the host status has been unknownР”В¬learStatistics method does as its name suggests, it clears all statistics, but offers a user the option to retain statistics that measure time durations.Р”Р„nd finally, the Save method will write ping options and host information using the provided XmlWriter object. How long the pinger has not been able to obtain IP address of the host from its name GetStatusDuration method provides this information Percent of recently lost packetsР”В¬urrent response time of the host Р”Р„verage response time of the host Maximal number of consecutively lost packets recorded Host's statistics provided by this class are listed below: Name/Description Void LogStatusChange(HostPinger host, HostStatus oldStatus, HostStatus newStatus) HostPinger class is built on top of the Ping class and it is in charge of pinging the host and calculating, storing and providing statistics about it.

Based on this simple method, we need to provide some meaningful and useful statistical information. PingReply reply = pinger.Send( new IPAddress( new byte ),Р”В«ut it is only one half of the story. PingReply reply = pinger.Send( ' localhost', 1000) PingReply reply = pinger.Send( ' localhost') PingReply reply = PingOptions pingerOptions = new PingOptions( 127, false) first parameter is TTL and second sets flag in IP header to // tell routers not to fragment the datagram The method has several overloads, but all of them return an instance of the PingReply class which contains results of echo request and response time. The heart of the class is the Send method that sends echo message and waits for the response. Ping class goes together with some other classes and data types such as PingOptions and PingReply classes and IPStatus enumeration. NET Framework that wraps this type of ICMP message to make your life easier and save yourself from implementing the protocol by yourself. As it was stated at the beginning of the article, you can use Ping class available in. The most common way to ping another host is to send ICMP echo message and then wait for the response from the targeted host.

In addition to these network tools, the application also tracks statistics about tracked hosts and allows the user to display those statistics as graphs. This article demonstrates the usage of Ping class located in the namespace in different scenarios such as host monitoring, tracing routes and scanning range of IP addresses.
