Free mrtg ping probe software for linux

mrtg-misc-probe probes different system features for mrtg to graph.
Currently it can probe:
- percent usage of disk space and inodes for UFS filesystems
- percent usage of disk space for VxFS filesystems
- incoming and outgoing mail messages on sendmail mail server
- total size of mail messages sendt and received on sendmail mail server
- network delay using NTP peers/servers
- number of ClearCase vobs and views
- number of available and used ClearCase and MultiSite licenses
- number of active and disconnected sessions of a Citrix Metaframe server
- number of reachable hosts in a given network range
- network device reachability (ping success)
Enhancements:
- New probes: ctxmf - number of active and disconnected Citrix Metaframe sessions; hostcount - scan given nmap-network-range and return number of hosts found.

mrtg-ntap-probe can probe for Network Appliance NetCache caching appliance and NetApp Filer.

mrtg-ntap-probe retrieves the disk and file (inode) utilization by volume or quota tree name, so you do not need to find the right OID, which might change over time as you add and/or remove volumes and quota trees.

You need a recent release of mrtg 2.x, perl 5.003 or better, a NetApp NetCache appliance with NetCache release 5.1 or better and/or a Network Appliance Filer running Data Ontap 6.0 or better.

If you have a Network Appliance service contract and access to their software tools library on now.netapp.com, you should also take a look at their mrtg-filer and mrtg-netcache packages!

BSNMP ping is a module for bsnmpd which allows you to measure latency and reachability. It sends out ICMP packets to the configured hosts.

A history of received packets is maintained, and you can query via SNMP how many dropped packets, maximum/minumum latency and other stats for that history period.

As bsnmpd only runs on BSDs (seems that way), this will also be the case for bsnmp-ping.

EXAMPLES

The following example pings two hosts. The first gets pinged once per second, and keeps a history for 300 seconds. The second is pinged 5 times per second, and the history is kept for 30 seconds.

The following would be added to /etc/snmpd.config:

begemotSnmpdModulePath."ping" = "/usr/local/lib/snmp_ping.so"
%ping
pingHost.1 = "10.8.9.2"
pingInterval.1 = 100
pingHistory.1 = 300

pingHost.2 = "2.2.2.2"
pingInterval.1 = 20
pingHistory.1 = 150

fping is a ping like program which uses the Internet Control Message Protocol (ICMP) echo request to determine if a host is up. fping is different from ping in that you can specify any number of hosts on the command line, or specify a file containing the lists of hosts to ping.

Instead of trying one host until it timeouts or replies, fping will send out a ping packet and move on to the next host in a round-robin fashion.

If a host replies, it is noted and removed from the list of hosts to check. If a host does not respond within a certain time limit and/or retry limit it will be considered unreachable.

Unlike ping, fping is meant to be used in scripts and its output is easy to parse.

Problem and Issues:

With a large a number of IP addresses in use, its becomes more and more time consuming to check on which IP addresses are actively in use, and which critical machines (routers, bridges, servers, etc) are reachable. One example is we have a program which goes through all of our routers arp caches looking for IP addresses that are in use. After finding a list of IP addresses that arent in any arp caches fping can then be used to see if these IP addresses really arent being used, or are just behind the routers. Checking 2500 hosts (99% of which are unreachable) via ping can take hours.

fping was written to solve the problem of pinging N number of hosts in an efficient manner. By sending out pings in a round-robin fashion and checking on responses as they come in at random, a large number of hosts can be checked at once.

Unlike ping, fping is meant to be used in scripts and its output is easy to parse.

Web Ping is a program for testing your internet connection.

Web Ping is a simple application to test an internet connection to a perticular site. I created this application after my work moved locations and half our network stayed in the old building and the other half moved with us to the new location.

A flaky (significant point) VPN was set up to keep the two connected. Since a couple of the unmoved servers were of interest to me, I keeped checking to see if they were still accessable with the ping command before doing any serious work with them.

A quick and pathetic Google resulted in no other program that meet my needes, so I wrote one.

Insted of doing an actual network ping, Web Ping tests a connection by downloading a web page on a given server. The size of the page and time are stored in memory and the times are graphed. In this way, sites that block network a ping can still be tracked.

Web Ping also keeps track of the largest and smallest download times per session and also tracks the max and min values currently on the graph. Times of interest are graphed in a color which represents if it is a max or a min. (see figure one). The history tab also lists all the max values as they have been recevied.

A running average is also calculated with each download. The files downloaded are not processed or stored in any way. This prevents any security problems that can normaly happen in a web browser enviroment. The only two pecies of information retained about a downloaded file is the size and time.

Usage:

There are two ways to use Web Ping, GUI or CLI mode. The simplest of the two modes is CLI. Web Ping can be started in CLI mode by passing a url to the jar file in a command line interface like this: "java -jar WebPing.jar http://localhost". Web Ping will automaticly start getting statistics on the requested url, printing results to the screnn.

To quite, press q and then then ENTER key. CLI allows the user to Most people will probably want to use the GUI mode which has a history graph and allows the user to start and stop the session.

The best way to run Web Ping is in GUI mode. GUI mode allows the user start and stop the ping process at will and to change the site that is pinged. Users can also see more information about about the history of the pings and view max values and min values easily. There are three tabs on the top of the page, the first is the application, second is the history list, and the last give information about the application.

KDE Ping is a network/IP ping utility for KDE.
