Open Source Network Monitoring Software

Simple Network Management Protocol (SNMP) .Net library written in C# (csharp). Implements protocol version 1, 2 and 3

Easy-to-use C++ library for various SNMP tasks. Is meant to be used as a C++ wrapper to net-snmp. Requires netsnmp-dev.

Python API library and shell utilities to monitor file system events. A simple program that uses watchdog to monitor directories specified as command-line arguments and logs events generated. Watchdog comes with an optional utility script called watchmedo. Please type watchmedo --help at the shell prompt to know more about this tool. You can use the shell-command subcommand to execute shell commands in response to events. watchmedo can read tricks.yaml files and execute tricks within them in response to file system events. Tricks are actually event handlers that subclass watchdog.tricks.Trick and are written by plugin authors. Trick classes are augmented with a few additional features that regular event handlers don't need. The directory containing the tricks.yaml file will be monitored. Each trick class is initialized with its corresponding keys in the tricks.yaml file as arguments and events are fed to an instance of this class as they arrive.

libnfdump provides simple API for reading files generated by nfdump tools. NOTICE: This is very first, experimental, version of the library. API will probably change in future versions. The library is based on slightly modified source codes of nfdump v1.6.12. It supports reading and filtering of flow records exactly as nfdump does. Aggregation, statistics and writing of new files is not supported yet. In addition to nfdump, the library allows to use several filters at once, in one pass over a file, which may reduce number of disk accesses significantly in many applications. Please, report any issues to ibartosv@fit.vutbr.cz.

This Perl library will help you writing Nagios3 Plugins.

snmpAdaptor4j is an adaptor for Java Management eXtensions (JMX) providing a simple access to MBeans via the SNMP protocol. Thus, this adapter you allow to connect most monitoring tools (like Nagios and Cacti) to your Java applications. For each MBean, an XML mapping file allows to establish the relationships between attributes and the MIB of the SNMP adapter. No additional code is necessary to integrate the MBeans in the SNMP protocol. This adapter can work in a multi-applications environment (such as application servers).

The Zabbix trap (zabtrap) client library allows you to send traps to a zabbix trap item configured on a zabbix server from your Java applications. For a full JMX Zabbix bridge (zabbix agent), check out http://www.kjkoster.org/zapcat/
