Cherry network monitoring / News: Recent posts

There are two major changes in this release, first is the fact that the connector between webapplication and collector daemon has been re-coded and doesn't suffer from 'reconnect' problems anymore. Second and most important update is the new SNMP stack that's being used. Westhawk SNMP stack is mucht lighter than the previous one, making the entire application about half its original size.

The complete list of changes:
- Changed SNMP libraries to Westhawk
- New daemon-web connector -> fixed connector issue
- Updated 'Monitoring - Overview' page
- Fixed history graph regeneration
- Added experimental upgrade option to the build script ... read more

Version 0.5 of the Cherry monitoring application allows users to monitor any SNMPv1 or SNMPv2 parameter and generate neat history graphs of them. Easy use by means of a webinterface, combined with a powerful and flexible script and graphing system make this a good alternative to monitor components (switches, routers, servers, anything really). Cherry is completely written in Java and based around the Open Source RRDtool for efficient storing and graphing of data.... read more

Cherry is a Web and Java based application built around RRDtool and used for monitoring and trend analysis of SNMP collected data. Extensive per component configuration and graphing abilities make this a useful tool for the network administrator.

Originally developed for a Belgian company the first release of Cherry is dubbed 'Ponder Stibbons'.

Features include:
- Basic authentication (read/write user)
- Basic (fixed) network topology information system
- Fully configurable through a web interface, once set up, not necessary to edit configuration files
- Automated monitoring of all kinds of numerical SNMP data
- Easy per component configuration based on SNMP retrieved interface list
- Extensive per component configuration, allowing multiple monitorscripts to be run for a same component,
but at different intervals
- Simple and efficient re-use of monitoring and graphing scripts by means of templates
- Graph configuration and generation using the full power of RRDtool graphing capabilities
- Efficient storage of data by the use of RRDtool (once a database is written, it never grows in size)
- Simple baselining of data (baseline profiles), useful for trend analysis
- Multi threaded collector daemon for efficient collecting and storing of SNMP data for many components... read more
