Free mrtg eth probe 1.5.5 software for linux

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!

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.

ATutor is an Open Source Web-based Learning Content Management System (LCMS) designed with accessibility and adaptability in mind.
Administrators can install or update ATutor in minutes, and develop custom templates to give ATutor a new look. Educators can quickly assemble, package, and redistribute Web-based instructional content, easily retrieve and import prepackaged content, and conduct their courses online. Students learn in an adaptive learning environment.
ATutor is the first fully inclusive LCMS, complying with the W3C WCAG 1.0 accessibility specifications at the AA+ level, allowing access to all potential learners, instructors, and administrators, including those with disabilities who may be accessing the system using assistive technologies. Conformance with W3C XHTML 1.0 specifications ensures that ATutor is presented consistently in any standards compliant technology.
ATutor has also adopted the IMS/SCORM Content Packaging specifications, allowing content developers to create reusable content that can be swapped between different e-learning systems. Content created in other IMS or SCORM comformant systems can be imported into ATutor, and visa versa. ATutor also includes a SCORM 1.2 Runtime Environment (LMS RTE3) for playing and managing SCORM based Sharable Content Objects (SCOs).
ATutors base in Open Source technology makes it a cost effective tool for both small and large organizations presenting their instructional materials on the Web, or delivering fully independent online courses. Comprehensive help is available through the ATutor HowTo documentation, through a number of support services, or through the public forums, and full language support is available through the ATutor Translation Site.

MRTG short from Multi Router Traffic Grapher is a tool to monitor the traffic load on network-links.
Routers are only the beginning. MRTG is being used to graph all sorts of network devices as well as everything else from weather data to vending machines.
MRTG is written in perl and works on Unix/Linux as well as Windows and even Netware systems.
Enhancements:
- SNMVv3 handling was improved.
- Support for SNMPv2/3 devices WITHOUT HC counters was added.
- Indexmaker parsing was made more robust.
- Netware support was updated.

MRTG::Parse is a Perl extension for parsing and utilizing the logfiles generated by the famous MRTG Tool.

SYNOPSIS

use strict;
use MRTG::Parse;

my $mrtg_logfile = "/var/www/htdocs/mrtg/eth0.log";
my $period = "day";
my $desired_unit = "GB";

my ($traffic_incoming, $traffic_outgoing, $traffic_sum) = mrtg_parse($mrtg_logfile, $period, $desired_unit);

print "Incoming Traffic: $traffic_incomingn";
print "Outgoing Traffic: $traffic_outgoingn";
print "= Sum $traffic_sumn";

This perl extension enables its users to parse and utilize the logfiles that are generated by the famous MRTG (Multi Router Traffic Grapher) tool.

mrtg_parse() takes three argument:

1st: filename of the mrtg logfile
2nd: time period to genereate the output for
valid values are:
- individual time periods like: 20040821-20050130 (ISO 8601)
- static values: day, month, year
3rd: the desired unit (optional)
valid values are:
- B, KB, MB, GB, TB
- if missing mrtg_parse will chose an adequate one for you
mrtg_parse() returns three values:

1st: Incoming traffic
2nd: Outgoing traffic
3rd: Sum of incoming and outgoing

fprobe is a small NetFlow probe which will listen on a network interface. It isusing libpcap, aggregate the traffic and export NetFlow V5 datagram to a remote collector for processing. A flow is identified by ip protocol, source ip, source port, destination ip, destination port.
Right now only ethernet interfaces are supported. Support for more media types (tunnel, ppp etc) will be added in nex versions.
/fprobe -t IP:PORT [ -i interface ] [ -s scan ] [ expression ]
-t IP:PORT NetFlow collector address
-i interface interface to listen for traffic (default eth0)
-s scan interval in seconds between two flow tables scans (Default: 10)
-c file file with MAC definitions
-p dont put the interface in promisc mode
-b go in background (daemon mode)
-l file log file name
expression a bpf expresion to filter traffic (See libpcap/tcpdump)
For example:
./fprobe -i eth2 -t 127.0.0.1:8182
This will sniff the traffic on interface eth2 and will send the NetFlow data to localhost (127.0.0.1) on UDP port 8182.
Internal flow table is parsed every scan seconds for expired flows which are sent to remote collector.
Enhancements:
- can handle IP fragments
- can set the snmp interface ID based on source/destination MAC address
- fixed uptime in exported flows
- new hash function for internal storage
- delay between udp datagrams emited
