Below is a list of my favorite server applications,
- Monitoring: Zabbix (open source)
An excellent enterprise monitoring tool for your servers and/or other network devices. It can monitor via basic ping, SNMP, Linux/Windows agent, and others.
However, the graphing module dynamically generates the graph images, and can become quite slow after a year of gathering data.
- Monitoring statistics: Observium (open source)
Observium is a network monitoring tool, that uses SNMP and Check_MK to gather data, and generates static graphs.
- Website statistics: Piwik (open source)
Best free website statistics engine out there, with a lot of similarities with Google Analytics, but goes further. For me the best feature is the Visitor Log.
- CMS for developers: MODX Revolution (open source)
MODX is a CMS built for developers, allowing the use of a template language, chunks and advanced snippits of code.
- Alternative CMS (blogging, ease of use): WordPress (open source)
Quick & Easy way of starting a blog, small/personal website. But can also be used for larger sites via additional plugins.
- Support / Ticketing: Atlassian Jira (proprietary, $10/year for basic license)
Great tool for managing tickets, both for development as for support.
- Wiki / Documentation: Atlassian Confluence (proprietary, $10/year for basic license)
Best corporate wiki, useful for managing internal & external documentation, FAQ, portal, etc.
- Document Management System / Portal: Alfresco Community Edition (free)
A document management system with a nice ‘file explorer’ design, can be used via web interface, FTP, SMB/CIFS and NFS.
- Telecom Soft-Switch: FreeSWITCH (open source)
Stable and performant soft switch, supports a variety of protocols (SIP, Google Talk, H323, IAX2 and SCCP), allows for flexible configuration and provides an advanced API.
- Host Intrusion Detection System: OSSEC (open source)
OSSEC performs log analysis, file integrity checking, policy monitoring, rootkit detection, real-time alerting and active response.
- CRM: SugarCRM (hybrid), vTiger (open source) or Zurmo (open source)
Both SugarCRM and vTiger include standard CRM modules and allow for additional modules to be installed. SugarCRM is more polished, GUI wise, but does not provide all modules in the open source version. Zurmo is a very new, and thus basic, CRM, but has a ‘gamification’ engine, giving users badges upon specific task completion.
Let me know which other applications you prefer and why.
